Transforming energy

As we come to the end of the Oil Age, there is a general acceptance that the next era of human existence will have to be powered by renewable energy sources. This level-headed, non-cranky analysis examines how the three key alternative energy sources - solar, wind and biomass - are being developed for everyday applications and how they point the way towards genuine energy sustainability for future generations.

·          A property developer who builds housing estates where you buy a package consisting of a fuel-efficient home, an electric car that plugs into the garage at night and a share in the estate's renewable energy power plant.

·          A commercial company that manufactures some of the world's biggest wind turbines.

·          A builder who builds super-efficient houses that cost less than a dollar a day to heat.

·          Activists campaigning for a more level playing field between traditional and renewable energy sources.

·          A leading biomass scientist who demystifies the production of ethanol-based fuel for vehicles.

·          A remote family home in Iowa powered solely by solar and wind.

·          A number of leading global commentators giving their perspectives on the macro issues.

The film serves as a reminder that alternative energy has moved beyond the sphere of the crank and into the lives of everyday families and commercial businesses.

"There is little doubt that we can create a sustainable world with the use of even our current technology. Whether we will or not will depend on the commitment, the passion, the spirit of so many different kinds of people whose life energy can transform, even save, our world."
