Cutting greenhouse gas emissions does not harm the economy. From 1990 to 2010 Germany cut emissions of carbon dioxide by about 25 percent, while the economy grew at a constant rate. Renewable energies are a driving force in the German industry, generating 37.5 billion Euros in turnover in 2010. The number of people employed in the renewable energy sector will go up to 500,000 by 2020 from today’s 367,000 people.
