Renewable Energy

Power from the wind, sun, land. It's renewable!

Renewable energy comes from renewable sources, including sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy technologies collect this energy to heat our water, generate our electricity needs, cook our food, and cool our homes.

Installing renewable energy technologies in your home is an investment in the environment and in our future, and there are many options to explore.

Solar energy

The sun provides us with light and heat. Sunlight is a renewable resource that can be captured through solar photovoltaic or solar thermal technology systems. Both systems collect the sun's rays, but solar photovoltaic systems are used to produce electricity and solar thermal systems are used to produce heat.

Geothermal energy

Geothermal energy uses the constant temperature in the Earth to heat and cool buildings. A series of pipes are dug into the earth and connected to a pump. This pump uses a basic refrigeration cycle to capture and distribute heat from the ground into a house during the winter, and from the house into the ground during summer.

Wind energy

Wind energy results as the wind blows and turns the blades of large windmills, also called turbines. This motion generates power that is converted to electricity. Wind turbines are often associated with large wind farms, but some individuals have them for home energy needs. These are more common in rural areas, as most cities and towns have by-laws in effect that restrict the height of structures.

Wind energy is the fastest growing energy source in the world with a growth rate of 11% and more each year!
