​(5) When it comes to energy efficiency, the leader of the renewable
energy pack is wind energy. Behind wind comes geothermal
energy.
hydropower, nuclear energy, and then solar power. Wind power
serves both individuals and entire communities. It is versatile, and
can be produced from small-scale windmills or wind turbines on
residential properties. It can also be produced from large-scale
offshore wind farms in the ocean.




(6) We generate geothermal power by tapping into underground
reservoirs of hot water and steam. Geothermal electricity can
directly heat and cool buildings. Generated from the energy of
moving water, hydroelectricity (also known as hydropower) is
produced when water behind a dam causes turbine blades to move
as it flows through an intake. The turbine blades then rotate a
generator to produce electricity that is sent to power homes.




(7) Nuclear energy is created in the form of heat through the fission
process of atoms. The initial fission process creates energy and
triggers a chain reaction that repeats the process and generates
more energy. In nuclear power plants, the heat that fission
produces
creates steam. The steam then rotates a turbine, which leads to the
production of electricity.
