Welcome to
Reiner Lemoine Institute


The goal of the institute is to scientifically support the long-term transition of the energy supply to 100% renewables. The institute’s basic funding is provided by Reiner Lemoine-Stiftung. Reiner Lemoine was a pioneer of renewable energy. While others were thinking and talking about alternative forms of energy, Reiner Lemoine took the lead and founded the solar companies SOLON and Q-Cells, amongst others.
