Ask the average green building professional about solar energy and they will tell you they know how to capture the sun’s energy via either photovoltaic solar or solar thermal.

Learn how to properly tap into the world’s biggest battery with ground source heat pumps and geothermal exchange, a technology that Natural Resources Canada (NRCan) and the US Environmental Protection Agency state is the most energy-efficient, environmentally clean, and cost-effective space conditioning system available on the market today.
