Biomass

Biomass is organic material from living or recently living organisms that contains stored energy from the sun.

Hydropower

Hydropower is a form of renewable energy that uses the force of falling or flowing water to generate electricity.

Renewable energy standard (RES)

A renewable energy standard requires that a certain percentage of electricity comes from renewable sources, such as wind and solar. May also be known as a renewable portfolio standard (RPS).

Renewable portfolio standard (RPS)

A renewable portfolio standard requires that a certain percentage of electricity comes from renewable sources, such as wind and solar. May also be known as a renewable energy standard (RES).

Renewable energy

Renewable energy is energy that is produced from natural resources that regenerate and can be sustained indefinitely. Michigan’s renewable energy standard includes wind, solar, hydropower and biomass.

Solar energy

Solar power is the conversion of sunlight into electricity. Sunlight can be converted directly into electricity using photovoltaics, also known as solar cells. It can also be converted indirectly into electricity through solar thermal/electric power plants.

Wind power

Wind power is the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power which is then converted into electricity.
