Our company is dedicated to the design and implementation of energy efficient software tools. As phenomena like climate change, outgoing natural resources, and nuclear threats become more and more obvious, the German government declared the energy-turn (Energiewende). The goal is to replace fossile (oil, gas, coal) and nuclear energy by renewable energy (wind, solar, water, biomass) and to reduce energy consumption in general.
