Renewable Energy

Renewable energy is defined as energy that is produced by natural resources such as sunlight, wind, rain, waves, tides, and geothermal heat that are naturally replenished within a time span of a few years. Renewable energy includes the technologies that convert natural resources into useful energy services:

• Wind, wave, tidal, and hydropower (including micro- and river-off hydropower)

Solar power (including photovoltaic), solar thermal, and geothermal

• Biomass and biofuel technologies (including biogas)

• Renewable fraction of waste (household and industrial waste)

Household and industrial waste is composed of different types of waste. Some parts are considered renewable energy sources for example, potato peel whereas other parts, such as plastic products, are not. Only the fraction of waste that is naturally replenished is usually included in the definition. In this book, however, for practical reasons, the whole waste fraction is included as part of the renewable energy sources identified in most analyses.
