Through its energy and climate policies, the U.S. has set recently a number of ambitious goals (e.g. by 2020 the share of renewable energy sources should increase to 20% of total energy consumption). At the same time the use of RES in the U.S is still significantly low compared to the European Union (EU). Therefore, it is particularly important to support information flow, raising awareness, and involvement of organizations in RES research and technology demonstration projects. The U.S. currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are non-renewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve.
