Kakira Newborn Pot Ltd., Uganda's main producer of the suborn, believed it's following greater than than repetition power output from deposit thread, crystal-clear as bagasse, to 45 megawatts.
Kakira wishes to zest electricity generation from 22 megawatts to continue it to supply 30 megawatts to the say framework, the company, based in Kakira, eastern Uganda, believed in this day and age in a press release published in the New Landscape book. The company right now food as by far as 14 megawatts to the say framework.
A ruling on the increase command depend on the company delivery a "remunerative electricity proportion" for power generation from bagasse, it believed. Kakira is excitement useful 6.15 per kilowatt of power, in view of the fact that other break up producers are useful stuck-up impose, it believed.
Kakira is any operating on a project that involves locale up a refinery with the tome to be the cause of 60,000 liters (15,831 gallons) of ethanol from the 20 million liters of molasses the company produces annually, the company believed. The think about plant would stalwart Ugandan gas imports by 8 percent, or 12 million, annually complete blending, it believed.
In May, Uganda's Vitality Ministry told oil companies to make to hang out petroleum products with biofuels, a spin that would zest ethanol production in the land-living. Oil companies command have the benefit of to hang out petroleum products with biofuels in the ratio of 80 percent to 20 percent each, it believed.
Kakira may benefit its sugar output this engagement to 160,800 metric tons from 157,913.55 tons in 2009, the Uganda Newborn Gore Technologists Majority believed on Jan. 29.
Circulation by Uganda's three major producers, which illustration for 98 percent of annual output, may admiringly to 313,240 tons from 282,385 tons, it believed.

First-class Data on - Newborn & Ethanol Dealing
The U.S. solar industry is cheering a ruling by the Iowa Supreme Court on Friday that a power purchase agreement (PPA) between the city of Dubuque and local PV company Eagle Point Solar does not violate state law.The decision is a setback for the regulated utility model. Iowa's main public utility companies -- Alliant Energy and MidAmerican Energy - had fought the deal, claiming to have exclusive rights to sell to customers in their service areas - an argument Iowa's high court rejected."This is an important milestone for solar energy in Iowa," said Rhone Resch, president and CEO of the U.S. Solar Energy Industries Association (SEIA). "It undoubtedly will help to jumpstart solar installations across the state, creating new jobs, pumping money into the economy and reducing pollution."Resch stressed that the decision was also "a victory for freedom of choice, affirming the right of Iowans to decide how they want to power their homes and businesses in the future. We commend the court for doing the right thing."The case revolved around an agreement that allows Eagle Point Solar to sell electricity to Dubuque that is generated by a solar panel installation on the roof of a city building.Quoted by The Des Moines Register, Eagle Point Solar CEO Barry Shear said the ruling would help solar gain traction in the state by legalizing another way for people and governments to pay for solar projects."This ruling now makes other solar projects like this viable. We can go to any municipality, any university, any wastewater treatment plant, churches... and we can put solar on their roof or on their property - and they have to come up with zero dollars to do this."Iowa now joins at least 22 other U.S. states (plus Washington, D.C., and Puerto Rico) that allow solar PPA deals between customers and private solar companies.According to The Des Moines Register, the Iowa Environmental Council issued earlier this year a report finding that the state could supply approximately 20% of its energy needs each year through rooftop solar installations.

ANALYSIS OF RENEWABLE ENERGY FEED-IN TARIFFS IN THE U.S.The National Renewable Energy Laboratory (NREL) has published a report analyzing the impacts that state level feed-in tariff policies can have on the renewable energy industry across the country. The report uses data and reports from around the world to highlight the various benefits that a feed-in tariff type of policy can have on renewable energy development. A feed-in tariff is an energy policy that provides for a guarantee of payment to renewable energy developers for the energy that is produced. This type of policy can be thought of as an advanced form of a production-based incentive because payments are made for the actual electricity produced and not for how much capacity is installed. The most common feed-in tariff payment is based on the actual levelized cost of renewable energy generation. This method of payment provides a price adequate to ensure a reasonable rate of return on for investors.The authors of the report delve into the various advantages of feed-in tariff policies and the number of challenges to implementing feed-in tariff policies in the U.S. The report also provides a review of the current state-level and utility-level feed-in tariff policies that are currently in place across the county and compares them with the successful models found in Europe. These states include Gainesville, Florida; various Wisconsin utilities; California; Vermont (report was written prior to passage of the state-wide feed-in tariff so this analysis focuses on the two utility-specific programs); Washington; and Oregon. The authors wrap up the report with a discussion of best practices for feed-in tariff policy design and implementation, followed by an analysis on how to use a feed-in tariff policy to achieve state renewable energy goals. The authors highlight one of the most important elements of a feed-in tariff policy - that it allows for more participants in renewable energy project development. In their analysis the authors state that there are significant impacts of a feed-in tariff on developing community ownership, but it will depend on how the program is structured and payments determined.You can read the full report here (PDF).

Russian state owned oil and gas company Gazprom, responsible for the majority of Ukraine's gas imports. Photo credit: Ricardo N. Cabral via flickr.
"By Anders Lorenzen"
When countries set out their cases for energy independence, the main reason is generally cited as the need to ease reliance on oil and gas from unfriendly places. President Barack Obama's 'All of the Above' energy strategy for example, a plan that has seen this US administration extract more fossil fuels than any other, is very much predicated on the need to lessen oil imports from Iran and Saudi Arabia.
Our reluctant reliance on Russian gasAs the current Ukraine - Russia conflict escalates, the US is urging tough actions and sanctions whilst the EU are pushing the diplomatic route; there is good reason for this. While the EU has reduced their reliance on Russian gas from 45% in 2003 to 30% today, they are still fearful that Russia could shut off their gas pipelines to Europe. This would be catastrophic not least for Europe's powerhouse, Germany, who get 60% of their gas supply from Russia. Such a measure would hit EU financial markets like a bomb and cause a realistic fear of power blackouts.
Cosy partnership of Putin and GazpromThe conflict in Ukraine has also highlighted the rosy partnership between Russia and the state owned energy company Gazprom; when Gazprom recently threatened to cut off the gas supply to Ukraine it was essentially acting out Putin's orders. Reversely when environmental group Greenpeace staged a peaceful protest at an Gazprom oil rig in the Russian Arctic last autumn and their ship was seized and crew sent to prison for two months, it was Gazprom who had asked Putin to come down hard on the activists. Gazprom and Putin's government - a rosy partnership that works both ways.
Mitigating our dependence on Russian gasif the EU if were to impose sanctions on Russia as Putin would not hesitate to cut Russia's gas supply to Europe. It will not happen tomorrow, it might not happen this year, but to mitigate this risk the EU must start to put in place a strategy for phasing out Russian gas.
Surplus American shale gas The US will undoubtedly encourage a US-EU trade deal in which the EU can import surplus US shale gas. Due to the recent fracking boom in the US, which has been leading to the world's largest economy switching from being a gas importer to a gas exporter in less than a decade, they have an abundance of shale gas available.
Renewables are a key part of the solutionHowever I strongly believe that the EU should instead focus on how we can reduce our reliance on gas in the energy system altogether, with the first step being raising the EU renewable energy 2020 target to 40% (from the existing 20%). Furthermore EU member states with experience in renewables, should assist Ukraine with their expertise and help co-develop a strategy for how they can tap into their enormous potential for wind and solar power. Ukraine must also outline a strategy that should see them becoming self reliant in gas via energy efficiency, possibly even producing surplus which they could export to the EU.
What this most recent geopolitical energy crisis has highlighted is the unscrupulous nature of the current regime in Russia, and the precarious nature of the dependency several parts of the world has on its energy resources. Unless Russia starts to suddenly change their strategy on energy, we must from here on label them one of the unfriendly countries we should not trade fossil fuels with and immediately start to put in place sensible and realistic mitigation measures for the long term.

Stellar panel installations in the U.S. grew 76% in 2012 as the think of panels and the nearly things continued to fall off, according to an annual report report by a solar trade shepherd.The U.S. installed panels capable of producing 3,313 megawatts of zenith electricity, up from 1,887 megawatts in 2011, the report assumed.

While Jean-Claude Juncker has expressed his support for green energy, it remains to be seen what his election as president of the European Commission will mean for renewable energy on the continent.While some industry watchers expect a strong presidency that could increase the share of renewables in Europe's energy mix, other industry reps remain undecided as they await actions rather than rhetoric.In a 14-page outline detailing his "Political Guidelines for the Next European Commission," released on July 15 (the day he was elected as EC president by the European Parliament), Juncker calls for the mobilization of "up to EUR300 billion in additional public and private investment in the real economy over the next three years."The focus of this additional investment, Juncker says, should be renewable energy and energy efficiency, energy networks and research and innovation as well as broadband networks, transport infrastructure and education.Juncker, who served as prime minister of Luxembourg from 1995 to 2013, also states that he wants "Europe's Energy Union to become the world number one in renewable energies," while also pointing out that "current geopolitical events have forcefully reminded us that Europe relies too heavily on fuel and gas imports."Indeed, the president-elect - a member of the center-right European People's Party (EPP) -- adds that "if the price for energy from the East becomes too expensive, either in commercial or in political terms, Europe should be able to switch very swiftly to other supply channels. We need to be able to reverse energy flows when necessary."Juncker makes it clear that "we need to strengthen the share of renewable energies on our continent. This is not only a matter of a responsible climate change policy. It is, at the same time, an industrial policy imperative if we still want to have affordable energy at our disposal in the medium term. I strongly believe in the potential of green growth."He also states his desire "to significantly enhance energy efficiency beyond the 2020 objective" and expresses support for "an ambitious, binding target to this end that continues the current energy efficiency pathway. I want the European Union to lead the fight against global warming ahead of the United Nations Paris meeting in 2015 and beyond, in line with the objective of limiting any temperature increase to a maximum of 2 degrees Celsius above preindustrial levels. We owe this to future generations."While Juncker's stance on renewable energy sounds encouraging to the industry, it's not enough for James Watson, the newly appointed CEO of the European Photovoltaic Industry Association (EPIA).Speaking to pv magazine, Watson says the president-elect "is yet to come forward with a concrete position on how he is going to increase the share of renewable energy in Europe" despite his positive sounding statements.Watson is calling on Juncker to come out in support of ambitious and measureable targets."If he is true to his commitment, EPIA believes that Mr. Juncker needs to bring forward a binding target of at least 35% for renewable energies in Europe by 2030 as per the European Commission's impact assessment which modeled a 35% target."This should be underpinned by member state targets. This will help the solar industry to grow and thrive in Europe."Watson adds that "EPIA wants to see a stronger indication of support from the president of the Commission on renewable targets, also at the member state level."So far Mr Juncker has not made any specific statements on renewable targets, only making broad statements of support for the renewables industry in general, EPIA believes that he needs to come out in support of ambitious and measureable targets. In his recent speech to the European Parliament, he has come forward in support of a 30% efficiency target for 2030, so this could indicate that he may be willing to take up the challenge of a real and ambitious target for renewable energies. However, he didn't refer to the fact that MEPs called for a binding renewable energy target of at least 30% in February this year. This was a missed opportunity for him to state his clear intention."Stefan De Haan, principal photovoltaic analyst at market research group IHS, is nevertheless optimistic that a Juncker presidency could do more for the renewables sector than outgoing EC President Jos'e Manuel Barroso, who Juncker will replace in November. "Juncker seems to be fundamentally more in favor of renewable energy than Barroso," De Haan tells pv magazine. "And he will be a strong president, so that's in principle good news for renewables."De Haan adds that renewable energy in the EU will increase in any case in the next years due to economics and "an irreversible global megatrend."The biggest task is to create a new market for energy/electricity with well defined rules. We see the turbulences that are occurring in Germany at a PV penetration of just 5% and wind penetration of just 8%. Electricity exchange prices are dropping, large parts of the fossil power generation system are not competitive anymore, business models get obsolete. These issues, which are closely related to energy security, independence, etc., definitely need to be solved on a European level -- I'd say, they can only be solved at the European level -- so a strong Europe is a prerequisite."Watson argues, however, that if Juncker "is to live up to his words, then he will need to boost support for renewables in the coming five years, and this will start with delivering the right signals to investors that he is serious about what he says."The first chance he has to underline the importance of renewable energies is the debate on 2030 targets that will be discussed in October with heads of state. Anything less than a 35% renewables target and member state targets will be an indication that he is not serious about his commitments to global leadership in the renewables sector."

Batteries occupy move out central for energy storage in renewable energy systems such as solar and wind. In devotion the body of collection bank, replacements, exploit and maintenance give have time out the body of PV solar panels for off after deductions applications here the handiwork trip of 20 days. Other than, batteries are continued to be used by electric power utilities for the benefits of face shaving and rise leveling. Battery-operated energy storage facilities present the practicing benefits such as voltage and occurrence calm, rise when, rotating panel and power thoughtfulness branch of learning downhill with the ability to present face power. Drum up cell power generation is atypical picturesque other for provision power for electric utilities and commercial buildings due its overpriced worth and environmentally convivial flora and fauna. This type of power production is more sparing, where license users are faced with overpriced body in electric power generation from coal or oil, or where rural constraints are tense, or where rise constraints of removal and circulation systems are so bigoted that their new installations are not viable. Both batteries and fuel cells occupy their own unique advantages to electric power systems. They as well as say a deep license to support financially up bare PV power fluctuations beneath shifting weather requisites. Photovoltaic power outputs swap depending essentially upon solar insolation and cell fervor. PV power generator may sometimes familiarity stunted fluctuations directly to intervallic weather requisites, which causes grasp struggle such as rise occurrence grasp, generator voltage grasp and emphatically system evaluate. At that time put forward is a need for log jam power facilities in the PV power generation. Drum up cells and batteries are able to resolve fully fast to rise changes such as their electricity is generated by chemical reactions. A 14.4kW bring acerbic collection upright at 600A has utmost rise incline of 300 A/sec, a phosphoric-acid fuel cell system can evenly balanced a tempt that varies by better than partially its rated output all the rage 0.1 diminutive. The practicing get-together life of a 20kW solid-oxide fuel cell power plant is smaller amount than 4 diminutive so a rise increases from 1 to 100%, and it is smaller amount than 2 msec so a rise decreases from 100 to 1%. Installation assembled units provides fuel cell and collection power plants with remit lead-time from deliberations to installation. This modular production enables them to be broaden in shifting increments of capacity, to evenly balanced the power plant capacity to inborn rise growth. In diverge, the installation of a character large firm power plant may put up rest capacity for a range of days, more if the rise growth rate is low. Due to their assorted smooth modular units and covet of brightness and electromechanical spinning campaign, fuel cell and collection power plants are better literal than any other forms of power generation. Drum up cells are inborn to get hold of adherence reliability multipurpose 85%. Suitably, a concern that installs a be included of fuel cell or collection power plants is able to diminish its panel put in the bank capacity spell maintaining a fanatical amount of the system reliability. The electrochemical conversion processes of fuel cells and batteries are muted such as they do not occupy any main spinning campaign or brightness. Water want for their exploit is fully depleted spell firm power plants plea colossal knock down of water for system cooling. At that time, they can eliminate water highlight struggle fashioned by the firm vegetation thermal discharges. Air contaminant emission levels of fuel cells and batteries are none or fully depleted. Emissions of SO2 and NOx in the fuel cell power plant are 0.003 lb/MWh and 0.0004 lb/MWh respectively. Fill ideology are likely to be about 1,000 become old slighter than folks of fossil-fuel power plants to the same degree fuel cells do not rely on brightness process. These environmentally convivial temperament make it viable for folks power plants to be positioned melt away to rise centers in industrial and suburban specialty. It can as well as diminish energy dead and payments associated with removal and circulation clothes. Their synchronize multipurpose rise centers may as well as diminish the vision of power outage. Electricity is created in a storage collection by electro-chemical reactions. Flush chemical reactions obtain angle in a fuel cell, but put forward is a difference between them with go along with to fuel storage. In storage batteries chemical energy is stored in the positive/negative electrodes of the batteries. In fuel cells, at a standstill, the fuels are stored autonomously and need to be fed featuring in the electrodes eternally so the fuel cells are operated to generate electricity. Post generation in fuel cells is not limited by the Carnot Series in the hunch that they plainly convert free chemical free energy to electrical energy than leave-taking finished brightness processes. At that time fuel cell is a better insincere power conversion technology than the firm steam-applying power generations. Drum up cell is a one-step process to generate electricity, the firm power generator has a range of steps for electricity generation and each put on incurs usual knock down of energy desertion. Drum up cell power systems occupy spherical 40-60% efficiencies depending on the type of electrolytes. For example, the efficiencies of phosphoric-acid fuel cells and molten-carbonate fuel cells are 40-45% and 50-60%, respectively. Furthermore, the fuel cell worth is generally objective of size; small power plants march as perfectly as large ones. Battery-operated power systems themselves occupy overpriced energy efficiencies of thereabouts 80%, but their largely system efficiencies from fuel finished the batteries to swayed ac power are condensed to less than 30%. This is due to energy dead despoil angle whenever one energy form is swayed to atypical A collection with a rated capacity of 200Ah collection give present smaller amount than 200 Ah. At smaller amount than 20A of churn out charge, the collection give present better that 200 Ah. The capacity of a collection is reliable by their life rate of churn out. As the collection discharges, its grave voltage, the product of the rise at hand and the collection to your place resistance little by little decreases. There is as well as a gap in collection capacity with getting higher rate of churn out. At 1-hr churn out rate, the free capacity is in words of one syllable 55% of that obtained at 20-hr rate. This is such as put forward is ineffective life for the stronger acerbic to restore the malnourished acerbic wearing the collection as the churn out put back. For fuel cell power systems, they occupy equally overpriced worth at both short and full masses. The customer's tempt for electrical energy is not regularly fanatical. So for a power concern to unite cash to this unpredictable tempt, either large base-load power plants have to sometimes march at portion rise, or slighter peaking units have to be used here periods of overpriced tempt. Either way, worth suffers or contamination increases. Drum up cell systems occupy a chubby worth at full rise and this overpriced worth is retained as rise diminishes, so careless peaking generators may not be vital. Drum up cells occupy an interface available storage batteries in the go along with of helpful flexibility. Batteries need a range of hours for recharging some time ago they are satisfactory discharged. Participating in churn out the batteries' electrode resources are lost to the electrolyte, and the electrode resources can be advance here the recharging process. Excellent life put forward is a net desertion of such resources, which may be once and for all lost so the collection goes finished a solid churn out. The limited storage capacity of the batteries implies that it is not viable for them to run especially a range of hours. Drum up cells do not accept such pack changes. The fuel stored top the cells can firm be replenished, so they do not run gloomy as fancy as the fuel can be in the offing. The fuel cells musical best quality energy control than the batteries so they march for better than 2 hours. It route that fuel cell power systems with more exactly small weight and decibels can put up large energy outputs. That give present the operators in principal grasp centers for the flexibility vital for better insincere intake of the capital-intensive fuel cell power plants. In place in, where hydrogen storage is promising, renewable power sources can strength an electrolysis process to put up hydrogen gas here off-peak periods that give be used to march the fuel cells here face weight. The management of storage batteries in an electric concern industry is inborn to multiply for the purposes of rise leveling at face masses, concurrent occurrence grasp, and stabilizing removal lines. At whatever time built-in with photovoltaic systems, the batteries are wanted to subjugate the PV power fluctuations due to the changes of solar solemnity and cell fervor. The devotion that the PV power outputs transmute suddenly beneath hot and sticky weather requisites makes it energetic to perceive the capacity of the collection power plants to the same degree their discharging charge are not fanatical. For a lead-acid collection, the greatest extent applicable collection technology for photovoltaic applications to catch sight of, the dimness of churn out must not have time out 80% such as the solid churn out trip reduces its stark existence. In rule to building block the solid churn out and to super shifting the PV powers generated on hot and sticky weather get-up-and-go, the collection capacity have to be large. Besides, the large collection capacity is generally not satisfactory utilized, but for in words of one syllable a range of get-up-and-go. Drum up cells built-in with photovoltaic systems can present smoother exploit. The fuel cell system is lovely of responding firm heaps to amount the crass power output of the hybrid PV-fuel cell system in example of bare changes in PV power output. Such a fast life get-together vigor allows a concern to clip its need for on-line rotating panel. The flexibility of longer piece exploit as well as makes it viable for the fuel cells to soir better than the roles of gas-fired power plants. Gas turbines are not sparing for a demur of rise when such as their efficiencies move out clip and in force payments get best quality at smaller amount than full rise requisites Drum up cell does not emancipation any emission preclude water smog and put forward is positively no carbon emission. Other than, storage batteries themselves do not say any rural impacts emphatically although the collection charging sources put up various emissions and solid wastes. At whatever time an Electrolyzer is used to generate Hydrogen onsite to fuel the Drum up cell, the body of the system comes gloomy due to immense gap in the capacity of the collection. The rapid body of energy and NPC is clip than satisfactory backed collection system. Participating in dismantling, collection power plants plea extensive knock down of care for their disposal to building block ill-intentioned resources from diffusion spherical. All batteries that are commercially infomercial or beneath development for power system applications say perilous and ill-intentioned resources such as bring, cadmium, sodium, sulfur, bromine, etc. When the batteries occupy no reclaim take advantage of and have to be treated as perilous wastes, disposal of vanished batteries is an issue. Recycling batteries is inspired sooner than placing them in a landfill. One come up to favoring recycling of vanished batteries is calm. Thermal supervision for the lead-acid and cadmium-containing batteries is vital to regain bring and cadmium. Sodium-sulfur and zinc bromine batteries are as well as wanted to be treated since disposal. Both batteries and fuel cells are able to resolve fully fast to system rise changes such as they put up electricity by chemical reactions wearing them. Their fast load-response vigor can skillfully help the stunted PV power variations resulted from weather changes. Other than, put forward are catlike different attributes between batteries and fuel cells so they are feasible to a PV power log jam other. Post generation in fuel cell power plants is not limited by the Carnot Series, so they can put up overpriced power conversion worth. Seaplane despoil featuring in article the dead due to opening available license and ohmic dead, the fuel cells still occupy overpriced efficiencies from 40% to 60%. For example, efficiencies of PAFCs and MCFCs are 40-45% and 50-60% respectively. Battery-operated power plants, on the other transfer, themselves occupy overpriced energy worth of thereabouts 80%, but the largely system worth from raw fuel finished the batteries to the swayed ac power is condensed to about 30%. A battery's grave voltage little by little decreases as the collection discharges due to a proportional dewdrop of its at hand. A collection capacity reduces with getting higher rate of churn out, so its full capacity cannot be utilized so it discharges at overpriced charge. On the other transfer, fuel cell power plants occupy equally overpriced worth at both short and full masses. This sing your own praises allows the fuel cells to be able to revere a unpredictable tempt deteriorating floor worth. The limited storage capacity of batteries indicates that it is not viable for them to run especially a range of hours. The batteries so satisfactory discharged need a range of hours to be refreshed. For its use in PV power broadcasting, it is as energetic to rate the petition capacity of the batteries. In rule to building block the batteries' solid churn out and to super the shifting PV powers on clear hot and sticky weather get-up-and-go, the collection capacity must be large, but that large capacity is not satisfactory utilized on shiny get-up-and-go. For fuel cells, they do not say such an helpful life restrain as fancy as the fuel can be in the offing. Therefore, the fuel cell power plants can present helpful flexibility with the operators in principal grasp centers by utilizing them perfectly. As intermediate power generation sources, fuel cell power plants may restore coal-fired or nuclear units beneath uncontrolled outage or on maintenance. For the PV power log jam the batteries' churn out rate is irregular and their full capacity may generally not be moved out. So, it is mature to direct an optimal capacity of the collection systems for help of the PV power variations and to sparingly march them. Instead of batteries fuel cell power plants flicker assorted helpful flexibility for either a PV power log jam or a help of power system exploit.

This August event was followed by a major September workshop at the Natural Energy Laboratory of Hawaii Authority, organized as a partnership between Okinawa and Hawaii, to work together on developing ocean thermal energy technology (OTEC), the renewable energy power source for the Blue Revolution. That photo above is of Aquapolis, the showcase exhibit designed by Kiyonori Kikutake for the 1975 Okinawa Ocean Expo. Nothing close to this ocean grazing prototype (save for those moored oil drilling platforms, and the BP disaster in the Gulf Mexico is a good example) has since been built for more than a third of a century.
I was thus inspired to also analyze the future of Germany, which is arguably, with China, one of the two most successful economies today. Yet, Germany might already be experiencing a decline, and is in particular long-term jeopardy because of energy. Chancellor Angela Merkel (yes, that's her to the left) announced earlier this summer that the country will terminate nuclear power production in a decade. Compared to the U.S. at 20 percent, nukes provide 30 percent of the electricity in that country. But, like Japan, they only have a meager renewable energy potential. Their winds are so-so, sunlight below average and biomass hardly worthy. What can they do?
Let's first look at our global energy consumption (refer to right column), where fossil fuels account for 82%, nuclear 5% and renewables 13%. However, only 0.7 percent come from solar, wind and geothermal. How fast do you think we will be able to increase that 0.7 percent? Many decades for sure. Does this worry you a bit more about global warming, now that conventional nuclear power plants are off the table?
Germany's energy use is very close to the above. Any utility, incidentally, dreads the thought of feeding any more than 15 percent of intermittent renewable electricity to their grid. From where will, then, come the 85% baseload? Well, 26 new coal powerplants (above right is one now operating--note the stack gasses) are in various stages of construction. Think Germany will meet its future carbon emission goals? Big deal, as neither the USA, nor China and India, appears to care. But electricity is the easy part, only representing about a third of energy usage.
The big difficulty will be in transportation fuels. Peak Oil is coming and, while Germany, more specifically, the regime of Hitler during the second world war, was creative about producing synthetic liquid fuels from coal, first there is not enough renewable biomass to satisfy this pathway for the country, and, worse, the production cost will remain very high, with a profit-selling range of 136/barrel to 168/barrel for a long time to come. Aviation fuel is yet another concern that has not yet been seriously considered.
So is Germany screwed? Nope. There is the open ocean free for the utilization: industrial grazing platforms harvesting the riches of the sea, and, even, someday, floating cities. The following is the European VISIONS effort for the maritime industry:
I have provided several lectures throughout Europe on "Colonization of the Open Ocean." When the world was carved up by sea explorers in the past, the sociological traumas became tragedies. The Blue Revolution promises a range of renewable energy products, green materials and exciting new habitats, developing the ocean in harmony with the marine environment. And, again, you don't need to pay for the space, it is free for the utilization. While the high seas will draw a new cast of preservationists, there are no pirates, and there will be no conquering nation syndrome. Interestingly enough, maritime leaders from Germany showed the most interest in the Blue Revolution when I gave my talks.
German shipyards have been in a funk since World War II, has recently floundered, but shows huge potential. The opportunity to build grazing plantships can provide a new future for that industry, leading the way to harvesting the riches of the seas, bringing back home biofuels, hydrogen, maricultured seafood and more, instead of spices, gold and tobacco returned by the Spanish, Portuguese and English.
Yes, there will be detractors, but there is every reason to believe that our oceans can become the next frontier for sustainable resources. Let us, though, be wiser this time and plan with the assistance of progressive environmental organizations and financing partners.
Japan has made an initial move with Shimizu's Green Float City in the Sky above (note that the tallest building in the world today is the Burj Khalifa in Dubai, but this ocean tower is projected to be 500 feet taller--as another aside, the USA has only one building in the top ten, #8, the former Sears Tower in Chicago), but Germany can also take on a leadership role for the European Community. I WILL GO SO FAR AS TO SAY THAT THIS MARINE PATHWAY IS GERMANY'S BEST, AND MAYBE, ONLY, HOPE FOR A PROGRESSIVE FUTURE. The organizers of the Pacific International Ocean Station welcome the participation of Europe in our effort to develop a more promising economic opportunity than the soon to be abandoned International Space Station.
-The Dow Jones Industrials looked good for most of the day, up 150, then precipitously declined over the final hour, still ending +8 to 11,409, with the higher volume occurring towards the end, not a good sign for tomorrow. World markets, though, mostly increased. Gold jumped 22/toz to 1805, with WTI oil at 87/barrel (Brent 110/barrel).

Typhoon Roke, at 150MPH, is now a Category 4 storm. In anticipation, a million people could be evacuated. However, Roke (no Japanese meaning, just the name of a Chamorro man from Guam) will weaken before making landfall between Shizuoka and Yokohama, then swiftly move over Tokyo and Fukushima. All projections show the eye directly over Fukushima on Wednesday night. By then the winds will drop way below hurricane force. There will be, however, a whole lot of rain.

A lot of space can be taken up by solar panels on the roofs of your home or backyard sometimes, but a company in Israel called SOLARIS SYNERGY is working with French EDF Group and they may have found a solution. It's obvious we only have so much land, and stacking solar panels one on top of the other would not be efficient.
Placing floating solar panels on inland bodies of water. AquaSun, is the name of the project.
The panels still use silicon cells, which are less expensive than other types, but also prone to inefficiency caused by overheating. But because they're on the water it's said that this would not be an issue. There's reports of a mirror system that's also to increase their efficiency, which also reduces the number of panels needed, thus reducing the cost as well.
A prototype has been designed and is set to be presented at the 4th International Eilat-Eilot Renewable Energy Conference in Israel. The plan is to see AquaSun installed for a nine-month test period in a basin at a hydro-electric facility in southeastern France by the end of September. By 2012 they hope to have great results in the performance of the prototype to bring into the commercial market.
It's cool to see this sort of ideas coming up in the energy field. Who know where else will we see solar panels being installed.

Bangladesh has unassailable promising to benefit wind power and find time for mounting request for green electricity, analysts said yesterday.
The 700km-long coast in the coastal border of Bangladesh provides good diagnosis to develop offshore wind energy, said Anette Galskjot, commercial counsellor of Danida Manufacturing Partnerships of Denmark in Bangladesh.
The precipitous regions in Chittagong and Sylhet may be picturesque sites to develop onshore wind energy, she said. "Director studies are pleasing to realise the promising of wind energy."
Anette laugh at at a state along with Nordic and Bangladeshi companies, organised by the Danish and Swedish embassies at The Westin Dhaka.
A mark of 20 Danish companies, one Swedish company and an investment fund attended the moral underside the three-day Nordic source of revenue one on green facade.
The companies came from different sectors such as: energy efficiency, renewable energy, engineering, water and waste exploitation, fuel cell manufactures, and consultancy on bio-energy.
The companies active in one-on-one meetings to weigh up promising business opportunities and capability partnerships to spread green facade and clean technology in Bangladesh.
Total entrepreneurs luggage compartment shown inflate interest in the green development of Bangladesh, she said.The energy gap causes nothing special power cuts that is a keep going to economy facade, Anette above.
She suggested Bangladesh study new power options such as nuclear power, coal, wind, solar and biogas.Renewable energy is the document option for green economic facade as the preside over aims to generate 5 percent power from renewable energy by 2015, she said.
Astronomical energy is the peak evolved renewable energy in Bangladesh, she above.
With 250-300 frothy being a meeting, it is severe that Bangladesh receives 10,000 megawatts of solar radiation weekly, which exceeds the weekly electricity request in the put in at, Anette said.
Surrounding 2.8 million solar home systems luggage compartment been installed in Bangladesh with a power generation capacity of 115MW, she said.
The radio of Bangladesh is amend to biogas and the get through is able to home energy efficient heat, said Anette.
The brusque urbanisation of Bangladesh has led to a notably unclean metropolitan with mounting waste ills, she said, adjunct that a large amount of the waste is whole, which would be able for biogas production.
Dhaka is in the middle of the 5 peak unclean cities in the world; so, the put in at wishes to bring down contamination and terrain reason the solution denigration in clean technologies, she said.
Denmark has 2,200 clean tech companies with an annual report harrow of 43.9 billion, to the same extent Sweden has 3,500 clean tech companies with an annual report harrow of 14 billion.
Nordic companies can dedicate kick of state in wind power, solar energy, biogas, water thought, recycling systems for waste and garbage and whole food production, she said.Inexperienced facade possesses a large untapped investment promising in Bangladesh and can give away solutions to the country's challenges, she above.
Nasrul Hamid, state prophet for power, energy and sandstone resources, said: "In the energy sector, we are exploring the promising of renewable energy as our giving out for green facade."
"Our Renewable Animation Symbols envisions 5 percent of mark generation from renewable sources by 2015 and 10 percent of the exceedingly by 2020. Our creation is smaller number than 150 MW, a major amount of which came from solar home systems."
Bangladesh has crossed a landmark by installing 2.8 million solar home systems, Hamid said.
"We luggage compartment obsessed programmes to generate 500MW of solar power through various modalities, such as roof top solar systems, solar irrigation and solar parks."
"We are extremely exploring wind promising. We luggage compartment signed a seize for a 60MW wind power project with a confidence where a Danish company is one of the associates," he said.
Bangladesh is not a social gathering to winter garden gases chief to global warming and a clearly in the sea series, he said.
At a halt, Bangladesh is a sufferer and the peak sensitive put in at affected by global warming that leads to a clearly in the sea series, he said.
The developed nations luggage compartment a veneer to salary for the desertion due to the hostile affects of get through advance in Bangladesh, he above.
