The document discusses the need for renewable energies as alternatives to traditional energy sources. It notes that conventional energies have negative consequences like excessive consumption, depletion of resources, pollution, and global warming. In contrast, renewable energies are inexhaustible and do not cause pollution or greenhouse gases. The document then provides examples of various renewable technologies like hydropower, solar photovoltaics, solar thermal, wind power, biomass, hydrogen, geothermal, and wave/ocean current. It also discusses the concepts of distributed energy generation using smaller local sources rather than large centralized plants, and microgrids which operate connected to but also semi-autonomously from the main grid. Energy production cooperatives are presented as a way for communities to

22. Microgrid
A microgrid is a localized grouping of electricity generation,
energy storage, and loads that normally operates connected
to a traditional centralized grid (macrogrid).
