As the world responds to climate change, we explore whether sustainable energy can satisfy our need for endless economic growth, without radical changes in the way we live. This album examines power sources which provide cleaner alternatives to fossil fuels, such as wind power, biomass, hydro power, wave and tidal power, solar and geothermal power. The nine video tracks introduce the different approaches adopted in Britain and across Europe, the challenges faced and the projects of the future. This material forms part of S278, Earth's physical resources: origin, use and environmental impact.
