Wind Power
• Converts kinetic
energy from wind, to
mechanical or electrical
energy
• Wind farm turbines
• Stand alone wind
turbines, connected to
a building
Wind turbine components

Geothermal energy
• It uses the constant
temperature of the
ground
• Used to heat or cool
buildings
• Ground-source heat
pump is needed in the
geothermal system
Air-source heat pump
• Can be used to lower
heating costs in a
building
• Air-source heat
pump can’t be the
only heating system
in a building
