According to the Federal Environment Agency, wind energy saves 0.67 tons of CO2 equivalents per megawatt hour produced. As an example, wind energy alone produced 36.5 TWh in Germany in 2019. This means that last year, wind energy saved about 24.5 megatons of CO2 equivalents. If this is compared with the 800 million CO2 equivalents emitted in Germany, the greenhouse gas savings amount to about 3%. Obviously, this is only a small percentage, but anyway a step in the right direction to mitigate climate change. Europe and especially Germany have still a high potential to profit-ably expand wind energy, both economically and ecologically.
