Everyone agrees that we have to overcome the current economic crisis. But how can we do this? In many countries, tax money is used to finance economic stimulation packages. This mainly boosts government debt, which must be repaid by future generations. Economic stimulus programs which do without government funding present a much better option. Governments and parliaments have to provide incentives for private investment through targeted regulation – this enables the creation of economic stimulus packages which revive the economy without amassing additional debts. This kind of option should simultaneously help to solve other serious problems, such as climate change and secure energy supplies. The Renewable Energies Act (EEG), which was introduced in Germany in 2000, is just this kind of stimulation package.
