The Energiewende is seen as a longer-term "investment" which comes with significant costs. The German government has spent about €500 billion on electricity subsidies to date. But it expects it will have beneficial outcomes out to 2030 in terms of economic development, as well as by creating a decarbonised energy system. Germany's "integrated" policy seeks to lower emissions across the country's electricity, industrial and transport sectors. It also seeks to increase energy security by reducing the country's coal, gas, petroleum and uranium imports.
