A better alternative would be a technology that involves biological intervention.

Levying a price on carbon dioxide released by electric generators could considerably reduce greenhouse gas emissions -- even before the deployment of any environmentally friendly technology -- according to scientists.

Researchers are developing a new, eco-friendly technology that could generate as much electricity as 50 wind farms.

They are investigating ways of painting solar cells onto the flexible steel surfaces commonly used for cladding buildings.
