20% renewable energy by 2020

The European Union has set itself the goal of raising the share of renewable energy sources in the final overall energy consumption of the Union from 8.5% in 2005 to 20% in 2020. This is an ambitious objective, but it is also a necessary contribution to the global fight against climate change and towards better control over our energy dependence. Governments have a crucial role to play through their good example and their support. But each individual can also help to achieve this objective. The various uses for renewable energy sources are examined: electricity for wind and hydraulic energies; electricity or heat for geothermal and solar energies; multiple applications: electricity, heat, and biofuel for biomass, the "Sleeping Giant".
