This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

DOE announced on September 8 that it will award $6.6 million in competitive grants for 15 state-level projects, nine of which focus on developing policy and regulations to support gigawatt-scale clean energy capacity, and six of which focus on developing advanced building codes. Of these awards, $4 million will go to the gigawatt-scale clean energy capacity projects, which will develop policy and regulatory frameworks that will enable gigawatt-scale clean energy, either through renewable energy or demand-side reductions. Although no cost share was mandated, state partners will contribute up to $1.8 million for these projects. The six advanced building codes projects will receive $2.6 million, which will assist states in developing and implementing residential, commercial, or overarching building codes. Along with its financial assistance, DOE will support these projects with ongoing technical assistance.

Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity. Speaking at the Euroscience Open Forum in Barcelona, Arnulf Jaeger-Walden of the European commission's Institute for Energy, said it would require the capture of just 0.3% The scientists are calling for the creation of a series of huge solar farms - producing electricity either through photovoltaic cells, or by concentrating the sun's heat to boil water and drive turbines - as part of a plan to share Europe's renewable energy resources across the continent. A new supergrid, transmitting electricity along high voltage direct current cables would allow countries such as the UK and Denmark ultimately to export wind energy at times of surplus supply, as well as import from other green sources such as geothermal power in Iceland. Energy losses on DC lines are far lower than on the traditional AC ones, which make transmission of energy over long distances uneconomic. The grid proposal, which has won political support from both Nicholas Sarkozy and Gordon Brown, answers the perennial criticism that renewable power will never be economic because the weather is not sufficiently predictable. Its supporters argue that even if the wind is not blowing hard enough in the North Sea, it will be blowing somewhere else in Europe, or the sun will be shining on a solar farm somewhere.

Mr Obama's stimulus includes calls for $38bn in direct government spending and $18bn in tax breaks for clean energy spread over the next 10 years, according to Dewey & LeBoeuf, the law firm. Owners of solar, wind, and other clean energy facilities will be able to claim tax credits against the cost of new equipment, helping attract big institutional investors who have been put off investing in clean energy because of uncertainty about taxes. But the short timeframe - credits can only be claimed for projects that are up and running within the next three to four years - means projects still on the drawing board may not be ready in time to qualify.

BOSTON (Reuters) - U.S. conglomerate General Electric Co (GE.N: Quote, Profile, Research, Stock Buzz) and Abu Dhabi investment agency Mubadala Development Co said on Tuesday they have entered into an $8 billion joint venture with an initial focus on providing commercial finance in the Middle East and Africa.The two companies also plan to work together in the clean energy and water, aviation, and oil and gas sectors, they said."This partnership is consistent with our global growth initiatives and builds on our long-term relationships in a high-growth region like the Middle East," said Jeff Immelt, chief executive of GE, the second-largest U.S. company by market value.The companies said Mubadala "plans over time" to become one of the Fairfield, Connecticut-based company's ten largest shareholders, by acquiring shares in the open market.They also aim to establish a clean energy technology center in Masdar City, a new city in Abu Dhabi that aims to be carbon neutral. GE plans to commit up to $50 million for Masdar's second clean-tech fund.Growth in the Middle East has been a major thrust for GE in recent years. Last year the company generated $5 billion in revenue in the region, up 50 percent from the prior year.

President Obama yesterday outlined plans to spend about $59 billion in economic stimulus funds and $150 billion from the federal budget to promote what he calls America's "clean-energy future." "We will attack the problems that have held us back for too long," including dependence on foreign oil, Obama told a gathering of clean-energy entrepreneurs and leading researchers at the Eisenhower Executive Office Building

ArcelorMittal (NYSE: MT), a steel manufacturer based in New Deli, launched a clean technology venture capital fund to support ventures that have relevance for the carbon-intensive steel industry. The Fund has made its first investment of US$20 million in Miasolé, a California-based pioneer in the development of thin-film solar panels Miasolé has developed unique high volume manufacturing processes that enable efficient production of Copper Indium Gallium Selenium (CIGS) solar products on a flexible stainless steel substrate. This technology promises to dramatically lowers the installed cost of Photovoltaic (PV) systems and will enable renewable energy from the sun to replace carbon generating fossil fuels. Fund managers will be working with leading venture capital firms, including Bessemer Venture Partners, Khosla Ventures, and Kleiner Perkins Caufield & Byers, to identify worthy cleantech ventures. ArcelorMittal also announced that it has created a new carbon fund in order to strategically engage in the carbon market and promote climate friendly solutions that are relevant for the steel industry. The fund, which has an initial investment commitment of €100 million (US$ 157 million) is currently looking at investment opportunities in renewable energy, energy efficiency, methane capture and greenhouse gas reducing technologies--all of which have the potential to generate carbon credits under the Kyoto Protocol. ArcelorMittal intends to use the carbon credits received from these Clean Development Mechanism and Joint Implementation projects for compliance in the EU Emissions Trading Scheme.

The redeveloped World Trade Center will be "one of the largest fuel cell installations in the world" according to the New York Power Authority (NYPA). Under the US$10.6 million agreement between NYPA and fuel cell developer and provider UTC Power, fuel cells with a total capacity of 4.8MW will provide an on-site supplement to the renewable and other clean energy that will power the rebuilt centre. The first fuel cells will be delivered to the Freedom Tower in January 2009, and will be owned and operated by the Port Authority, which also owns the building. The fuel cells for the other three towers will be owned and operated by World Trade Center Properties, LLC. "Fuel cells are one of the environmentally beneficial technologies that the Power Authority is investing in under Governor Paterson's leadership to combat greenhouse gas emissions and diversify the state's energy mix. To date, we've installed 15 fuel cells in New York City and other locations, and expect to add to this total in support of the Governor's ambitious goals for significant increases in the state's renewable power," says Roger B Kelley, NYPA President and Chief Executive Officer.

The visit seemed destined to be a genial affair in which Obama and President Piñera could celebrate energy cooperation and entrepreneurship, enter into a nuclear cooperation agreement and discuss the benefits of the clean and green economy. With the global energy calculus again once again shaken by dramatic events, that simple narrative is no longer plausible.

MOSCOW (Reuters) - Russia this week pledged budget funds for clean energy and called for limits on greenhouse gas emissions in a reversal of the country's earlier reluctance to embrace the Kyoto Protocol and energy efficiency.

Ireland's OpenHydro and Germany's RWE are spending millions to try to turn the power of waves into electricity With oil prices hitting almost daily record highs and global warming climbing up the public agenda, the need for alternative energy sources has never been more urgent. But while wind and solar have dominated the recent rush to invest in renewables, market watchers reckon it could now be marine energy's turn to shine. Ocean power-using the energy from waves or tidal flows to produce electricity-is quickly coming of age as a viable green resource that could help meet ambitious global targets to reduce greenhouse gases and dependency on fossil fuels. European and North American power companies such as Canada's Emera (EMA.TO) and Germany's RWE (RWEG.DE) are spending millions to fund wind and tidal projects. This investment has led to a new generation of more efficient technologies, with dozens of prototypes expected to be ready for commercial deployment within the next five years. "There's huge interest in both wave and tidal technology," says Thomas Boeckmann, clean tech analyst at market research firm StrategyEye in London. "It's gaining a lot of attention from energy companies, which will be able to offer financial backing and technical expertise to these startups."

"Green energy could give many more Indians access to electricity. "Forty per cent of India is still not connected to the grid," says Krishnan Pallassana of the Climate Group, an international think tank. "Clean energy, particularly solar and wind, could eventually connect these homes via renewable sources, and revitalise India's failing energy system.""

it is my professional responsibility - both to myself and to those I serve - to begin speculating how the current crisis may affect the realm of clean energy.

Venture capital is one of the pulses of the industry, and so a headline that VC investments are dropping by double digits is enough to catch the eye of anyone involved in the high tech ecosphere. But when you look at more data, things don't look bleak. On one hand, according to Dow Jones VentureSource, investment is down:\n\nIn the second quarter of 2008, quarterly venture capital investment in U.S. companies slipped below the $7 billion mark for the first time in 18 months. According to the Quarterly U.S. Venture Capital Report released today by Dow Jones VentureSource (http://www.venturecapital.dowjones.com), investment fell 12% in the second quarter compared to the same period last year with $6.64 billion put into 602 deals, the lowest quarterly deal count since 2005. The $7.58 billion invested in second quarter of 2007 was the second-highest quarterly totals recorded since the end of the dot-com boom in 2001.\n\nYet it's not all bad news because there was " steady deal activity and investment in the first half of the year," according to Dow Jones VentureSource director of global research Jessica Canning.\n\n"The movement of venture dollars from the traditional areas of information technology and health care toward burgeoning sectors like renewable energy, power management, and agriculture - or 'clean technology' areas - proves that venture capitalists are making good on their promise to tap opportunities in the massive energy market," said Ms. Canning.

Venture-capital and private-equity investments in the clean-technology sector more than doubled to nearly $6 billion across the globe in the second quarter, just as oil traded at record levels near $150 a barrel and the stock market moved lower on economic woes. Money for companies in the business of cutting carbon-dioxide emissions totaled $5.8 billion, up from $2.6 billion in the year-ago period, according to a report from research firm New Energy Finance, released Tuesday.
