Wind energy and other renewables are playing a reliable part in reducing Germany's greenhouse gas emissions. While oil and gas use still have the biggest impact on CO2 emissions, renewables contributed 15% more to energy supply in 2007 than in 2006, according to the federal environment office, the Bundesumweltamt. Wind energy produced 39.5 TWh of electricity in 2007 displacing the equivalent volume of fossil fuel generation and contributing 6.4% of gross electricity generation. The warm weather during the winter months of last year and consequent lower demand for oil and gas for heating was the main reason for the 2.4% or 24 million tonne drop in greenhouse gas output to 981 million tonnes. At minus 20.4%, this takes Germany close to its target to reduce climate gas emissions by 21% compared with 1990. But the warm weather was a one-off effect, warns the Bundesumweltamt. A further reduction of greenhouse gases can only be expected if the government diligently implements the climate protection package introduced in December last year. An important part of this package is the continued expansion of renewable energies.
