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

BLYTH, NORTHUMBERLAND, UK, August 4, 2008. The New and Renewable Energy Centre (NaREC) in the UK and CENER, National Renewable Energy Centre of Spain are working together to find new ways of generating and distributing power from small-scale renewables within communities. The one year project will investigate ways to allow communities to generate and use their own power from renewable energy resources, in a reliable and cost-effective way. With increasing use of renewable energy sources, a significant amount of interest has developed across Europe in so-called 'smart-grid' systems better capable of transmitting and distributing power from different renewable resources in a reliable, flexible electrical network. The team is currently identifying existing communities within Spain and the UK with populations of between 10 and 25 000 which can be used as test subjects for 'smart-grid' renewable systems. The project aims to demonstrate the most appropriate technical solutions for integrating low carbon power generation technologies into a localised, community-based electrical system.

Until November it was virtually impossible for a private developer of renewable energy power plants to become an independent power producer (IPP) in Mexico. Article 27 of the Mexican Constitution precluded private investment stating that electricity generation for public use is an activity to be undertaken exclusively by the Government. Mexico's enactment of a new law for the use of Renewable Energy and the Financing of the Energy Transition ( Ley para el Aprovechamiento de Energías Renovables y el Financiamiento de la Transición Energética ) substantially improves the legal framework for private investment in renewable energy projects. The law regulates renewable energy electricity generation for purposes other than providing public electricity services. The law states that the use of renewable energy for electricity generation is possible for private use and any excess energy can be sold, but only based on regulations and approvals by Mexico's energy regulatory body, CRE .

(Washington, DC) Some of the most influential and competitive organizations in the renewable energy industry have now joined together to create the first trade association for organizations that market renewable energy. The Renewable Energy Marketers Association (REMA) has formed to vigorously promote the economic and national security benefits of domestic renewable energy.

Wind energy's 32% growth rate in 2009 as an example of "the impressive growth rate of renewables" The total global potential for renewable energy "is substantially higher than both current and future projected global energy demand" is the message of the Special Report on Renewable Energy Sources and Climate Change Mitigation released by the UN Intergovernmental Panel on Climate Change (IPCC) today in Abu Dhabi.

According to NREL's Renewable Electricity Futures Study, the increased electric system flexibility needed to enable electricity supply-demand balance with high levels of renewable generation, can come from a portfolio of supply and demand side options, including: · Flexible conventional generation · Grid storage · New transmission · More responsive loads · Changes in power system operations

It's been a long, challenging endeavor, but there are signs that the economic ecosystem built up around wave and tidal power generation is at long last gathering enough momentum to make the jump from R&D-driven to full-fledged commercial industry. Scotland, with its long stretches of west-facing coastlines, North Atlantic latitude and longstanding tradition of maritime engineering and commerce, is now at the leading edge of change when it comes to fostering development of marine renewables. Wavegen's Limpet 500 system has been pumping electricity from the western Scottish Isle of Islay shoreline since 2000 while the company and project developer npower renewables have continued to move forward with plans to develop the Siadar Wave Energy Project, potentially the first under the Scottish government's Marine Supply Obligation program. Marine Current Turbines is getting ready to flip the switch and fully commission a grid-connected 1.2-megawatt (MW) Seagen tidal turbine-based system in Northern Ireland's Strangford Narrow, while elsewhere in the EU, project developers and the marine renewables community await the much-anticipated commissioning of Pelamis's novel, serpent-like wave power system off the northern Portuguese coast.

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.

A vote could come as early as this week in the U.S. Senate on a bill introduced by Senate Tax Committee Chairman Max Baucus (D-MT) and Senate Majority Leader Harry Reid (D-NV) containing a one-year renewable energy production tax credit (PTC) extension and a small wind turbine investment tax credit. The Senate bill, S. 3335, contains a one-year PTC extension at its current value. After December 31, 2009, any further extension would include the "presumption" of a cost cap, which would, through a complex formula, put a ceiling on the value of the credits of no greater than 35% of project value. The small wind ITC has a cap of US $4,000 per system.The 10-year cost for the PTC, including all technologies to which it applies, is projected to be approximately US $7 billion, while the ITC, which includes solar, would cost approximately US $907 million over 10 years. The bill also includes provisions to extend through 2014 the tax credits for solar energy, fuel cell and microturbine property, as well as the residential energy efficient property tax credit. Marine renewable energies could also benefit from the bill as credits to build wave, tidal, current and ocean thermal energy conversion systems of at least 150 kilowatts (kW) are extended through the end of 2011.

German renewable energy companies and bankers will meet officials in Berlin on Monday to discuss ways of preventing the financial crisis from casting a storm cloud over a vital domestic growth industry. Up to 30 companies and organisations are expected to outline the problems facing the renewables sector, whose bullish projections have been overshadowed by concerns about project finance, falling prices and delayed orders.

"A new research report says growing significance of renewable power generation will spur growth in the electrical transformer market for next few years with ABB Ltd., Alstom SA, General Electric (GE) and Siemens AG featured as key vendors in the industry."

"That's according to energy policy group REN21's just-released Renewables 2015 Global Status Report, which attributes this stabilization to "increased penetration of renewable energy and to improvements in energy efficiency.""

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.

Mainstream Renewable Power, a renewable energy company led by Airtricity founder Eddie O'Connor, has announced the successful closing of a €40 million [US $59.6 million] equity fundraising in which Barclays Capital have invested €20 million [US $29.8 million] for a 14.6% stake in the company. The board, management and staff of Mainstream, as well as close associates of the company, have invested an additional €20 million [US $29.8 million]. Together with the initial seed capital of €32 million [US $47.75 million], this brings the total equity raised to date to €72 million [US $107.43 million]. The company is also planning a major fundraiser later this year, with Barclays Capital committing to invest a further substantial amount at that stage. As part of the deal, Mark Brown, head of Barclays Capital Commodities Principal Investment team has been appointed to the board of Mainstream. The money will be used to fund the company's international expansion plans across Europe, North and South America and Australia and will be used to secure the supply of turbines to be delivered in 2009, 2010 and 2011. In June, Mainstream announced its plans to build an initial pipeline of 240 megawatts of projects in Chile with its partner Andes Energy.

Renewable energy needs to become a lot more renewable - a theme that emerged at the Financial Times Energy Conference in London this week.

Leadership in both the U.S. House of Representatives and Senate are calling on the Department of Energy (DOE) to allocate US $250 million of the $2.5 billion in stimulus funding for renewable energy research and development to the emerging marine renewable energy industry. The funding would help develop wave, current and tidal energy technologies

IEA's dire warning on green stimulus and renewables Kate Mackenzie, Financial Times The IEA's report for G8 energy ministers, to be presented this Sunday in Rome, has generated a few stories. Some picked up on the oil supply squeeze that awaits the world due to massive cuts in production investment. I wrote yesterday that the IEA forecasts that, for the first time since World War II, world electricity consumption will decline in 2009. IEA chief economist Fatih Birol said he personally thought the electricity forecast was the most striking finding of the report. However he was also keen to highlight concern about green spending in the G20 stimulus packages: The agency will also tell ministers that its calculation of the stimulus spending required from G20 nations on renewable energy was inadequate and should rise by a factor of six if greenhouse gas emissions targets set by the United Nations were to be met...
