What is Green electricity?
Electricity is 'green' when it is produced from renewable energy sources: the sun, wind, geothermal sources, water falls, tides and plants.Contrary to fossil fuels (coal, oil, gas, uranium) whose finite reserves are being consumed daily (energy 'stocks') these renewable sources are in theory inexhaustible (energy 'flows'). In addition these engender no direct CO2 emissions. These are the energies of the future.
An urgent situation for the planet
Today, climatic change is no longer simply a question of concern. It is now vital. However, in spite of the political will to support non-polluting energies and respect of the engagements fixed by the Kyoto Agreement in terms of reducing greenhouse gases (GHG) emissions, renewable energies still remain very largely under exploited, representing only 18% of the world's energy production (1).In spire of their almost unlimited potential, the benefits resulting from their exploitation are multiplex, both in terms of reducing CO2 emissions and the economic and social advantages.
