Solar energy

• Solar energy is generated by converting sunlight directly into electricity using photovoltaic cells. Solar power is one of the fastest growing renewable energy sources(7)

Wind energy

• Wind turbines convert the kinetic energy of wind into electricity. Wind power has become one of the cheapest energy sources in the U.S. and is a major renewable energy source(7)

Hydroelectric power

• Hydropower uses the energy of flowing water to spin turbines and generate electricity. It is the largest source of renewable electricity generation in the U.S(7)

Geothermal energy

• Geothermal energy taps into the heat from the Earth's core to produce steam that can be used to generate electricity or provide heating and cooling(7)

Biomass energy

• Biomass energy is generated by burning organic materials like wood, crops, and waste to produce heat or electricity(7)

Nuclear energy

• Nuclear power is not a renewable energy source, as it relies on finite uranium and thorium fuels. However, it’s often considered an alternative energy source since it doesn’t produce greenhouse gas emissions during electricity generation(8)
