Document Summary
Reliance on renewable energy is a characteristic of a sustainable ecosystem and society. Samso used to be like most communities on earth: fully dependant on fossil fuels. Renewable energy = energy from sources that are replenished over short time scaled or that are perpetually available. Sustainable energy = energy from sources that are renewable and have a low environmental impact. Wind energy = energy contained in the motion of air across earth"s surface. To become sustainable, samso would harness the power of its most plentiful natural resources. 11 onshore and 10 offshore wind turbines. Wind turbines can be large or small, all work by the same principles: spinning blades turn a shaft inside a generator and produce electricity. The most abundant source of sustainable energy is one that powers the entire plant - the sun. Solar energy = energy harnessed from the sun in the form of heat or light.
