Manufacturers are designing larger wind turbines capable of generating more electricity per turbine in an effort to improve these economics.

Together the projects are expected to create more than 500 wind turbines, generating 1, 500 megawatts of electricity - or 1.5% of the UK's energy needs.

While it is absolutely essential that we continue to drive down the costs of generating electricity from solar (and wind, which is indirect solar energy, ) doing so alone will not make these renewable energy sources competitive with traditional hydro, fossil or nuclear generated electricity.

He explains that the technology works by first generating electricity in the traditional manner of a wind turbine.

It says the world's installed wind capacity at the end of 2002 was 31, 128 megawatts, with Denmark the leading user, generating 20 percent of its electricity from the wind.

Indeed, various companies, including GE, are investing heavily in ways to come up with cost-effective systems to store the wind and solar energy that their wind turbines and solar technologies capture in combination with other means of generating electricity and power.

There are 3, 400 onshore wind turbines across the UK at 324 different sites, generating 3% of the UK's electricity.
