Factor 4 Energy Projects GmbH

(in the following Factor 4), is a manufacturer-independent consultancy firm for the application of renewable energy and sustainable energy projects. It derives its name from the latest report for the Club of Rome (Factor Four: Doubling Wealth, Halving Resource Use - A Report to the Club of Rome, by E. U. von Weizäcker, Amory & Hunter Lovins, 1995). This report argues that the industrial civilisation can only survive when the efficiency on both the input and output side of all industrial processes is doubled - hence, a factor 4 is needed for resource productivity. In other words: only through using half the amount of natural resources at twice the efficiency, industrial society can survive in the long run. At the same time, we can live twice as well and place half the stress on our environment.

For wind energy and other renewable energy technologies, technical advances have resulted already in a resource productivity beyond the factor 4, i.e. a contemporary utility-type wind turbine (~ 3,000 kW installed capacity) uses wind energy, as well as the natural resources for its construction, more than 4 times as efficient as the first generation wind turbines back in the 1980s.

Founded in 1995, Factor 4 Energy Projects has worked in all fields of new and renewable energies apart from large and medium-sized hydro power. In the wind energy sector, activities of Factor 4 covered all aspects from planning to operation, including site evaluation, utility personal training, project planning, resource estimation, tendering, supervision of installation, commissioning and wind park performance monitoring. Another focus of Factor 4 is the efficient use of biomass ressources (household energy) and the autonomous energy supply of (small) isolated grids/islands. Factor 4 is based in Wismar at the Baltic Sea in Northern Germany (approx. 200 km North of Berlin).
