- A project linking solar power from the Sahara to energy users in Europe and North Africa could create 240,000 German jobs and generate 2 trillion euros ($2,822 billion) worth of power by 2050, a study published on Thursday found.

The dramatic growth in wind turbines around the British Isles may lead to huge spikes in power prices by 2030 and threaten the viability of backup plants needed for calm periods, according to Poyry Energy Consulting.

Global investment in clean energy and climate-friendly technologies leapt in the last three months but full-year levels won't recover until 2010 or 2011, analysts said on Wednesday.

Falling energy demand and more expensive debt have hurt large renewable projects for example in wind and solar power. Recession has cut risk appetite, curbing funding for clean technology start-ups.

Current trends in energy supply and use are clearly unsustainable

The proliferation of wind energy as a viable alternative to fossil based fuels used in the production of electricity is well documented. (1) While media reports on the influx of wind power farms often shed a positive light on the use of wind for generating electricity, few reports have squarely addressed the challenges faced by states, municipalities, and investors in implementing such projects.

A Bangladesh-Japan joint venture has offered to generate 1,000MW power by installing environment-friendly windmills in Bangladesh.

The United States may become the largest market for renewable energy for E.ON, the world's largest utility by sales, within six years, the head of the company's green energy unit told Reuters in an interview.

Norway's government proposed a new law on Friday to develop sea-based wind power as part of a plan to diversify from offshore oil and gas toward renewable energy.

"Offshore wind energy may become the next adventure for the Norwegian industry and energy sector," Oil and Energy Minister Terje Riis-Johansen said in a statement of a draft bill presented by the center-left government.
