In this module, we have seen that to achieve energy sustainability we should begin with conserving energy and increasing energy efficiency. Energy conservation refers to finding ways to use less energy. Increasing energy efficiency means achieving the same amount of work from a smaller quantity of energy. Sustainable design of buildings and communities can decrease energy use. We also looked at different categories of renewable energy resources. Potentially renewable energy sources can regenerate if we do not consume them more quickly than they can be replaced. Nondepletable energy resources such as the wind cannot be depleted no matter how much we use. In the next module, we examine two important renewable resources, biomass and water that is used for generating electricity.
