Britain has 2,906 wind turbines spread over 264 sites with a further 7,000 turbines planned for the next 12 years.

The wind farms, to be built between 2011 and 2017, will eventually add 1,500 megawatts of capacity to Romania’s energy grid.

A study suggests that by 2030, more jobs will be available in the energy field if governments make the switch to renewables. If they stick to coal, the number of jobs will drop by half a million.

Breathtaking design and practical, clean technology are merged to give us the greenest skyscrapers the world has seen.
