One of the biggest renewable energy manufacturers in Britain announced on Tuesday it is to cut more than half its UK jobs - blaming the government for failing to support the sector. In a grave blow to the government's ambitions to create a "green" export industry, Vestas, the world's biggest maker of wind turbines, will axe about 600 of its 1,100 UK employees, probably closing its factory in the Isle of Wight and cutting jobs elsewhere in the UK.

Another one in a series of studies on this topic. This one predicts an 87,000% increase in the demand for battery materials which is not very helpful. Exponential extrapolation from a small basis over a long time horizon can basically come up with any growth figure. The logistic growth curve is a much better and proven model for technology transitions.

"Demand for cobalt, copper, lithium, cadmium, and rare earth elements needed for solar photovoltaics, batteries, electric vehicle motors, wind turbines, fuel cells, and nuclear reactors is set to explode in the coming years as countries around the world invest heavily in greening their economies".

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.

Last week the Spanish government announced plans to cut subsidies for solar photovoltaic (PV) power by about 75%. Although the nation expects to surpass its 2010 goal for installed solar by four fold, the down side is that generous subsidies for the industry have resulted in a ballooning tariff deficit for the country, which has risen to 4.85 billion euros, upfrom 745 million last year. Reuters reported that lending to the Spanish photovoltaic plants has risen to $3.59 billion in the year to day, up from $230.9 million euros last year and $192.44 million in 2006. As a result, the Spanish government will as the energy regulator to cap subsidies for new PV solar capacity at 300 megawatts (MW) per year--200 MW for rooftop systems and 100 MW for ground-mounted systems, which have been the highest growth area. CSP has been slower than PV technology in its emergence on the renewable energy scene, but expectations for the technology, which focuses the heat of the sun to produce steam to drive electricity producing turbines. Projects underway in the U.S. and Spain are expected to produce electricity that is cost-equivalent to electricity produced from burning coal or natural gas.

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.

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.

This main report is intended for government policy makers and organisations considering installing small wind turbines at their sites, but will also interest other readers.

Czech utility, CEZ Group (CEZ.BE), is investing 1.1 billion euros in a Romanian wind farm with a projected capacity of 600 megawatts (MW), which--when completed--will be the largest onshore wind farm in Europe. CEZ bought the development rights for two projects from Continental Wind Partners LLC (CWP), which will manage the construction, set to begin next month. The project will combine adjacent Fantanele and Cogealac wind farms. Together, the two projects will be about twice the size of the next largest fully permitted onshore wind farm in Europe, and triple the size of the largest operational wind farm in Europe. The project, which is located about 17 kilometers from the Black Sea, will be completed in two stages. The first stage of 347.5 MW is expected to be completed by the end of 2009. It will comprise 139 GE wind turbines.

HYBRID-electric vehicles (HEVs) could become cheaper thanks to a breakthrough that would allow inexpensive lead-acid batteries to replace the nickel-metal hydride (NiMH) batteries they now use. Similar battery systems could also be used to smooth out fluctuations in the power output of wind turbines.
