The Nature Energy Development Fund (NEF) promotes the sustainable development of renewable energy sources by means of investment, directing the production of bioenergy to regions and countries that are best suitable for this purpose. Both the investors and the countries in question benefit from an approach that places renewable energy plants at location that are best suitable for their operation. Thanks to its experience in the field of sustainable energy and its in-depth knowledge of the market, NEF is in a position to choose the best locations for its projects. The key criterion for all NEF project is thereby the principle of sustainability, which simply means that resources should only be used at a rate at which they can be regenerated.
