Client Comments:
"Positive Energy homes use non-carbon-based sources of energy to produce 100% of the energy needed for appliances, heating, and lighting. Additionally, the home generates enough energy to power an electric car. Most importantly, a positive energy home does not produce carbon emissions, which are responsible for global warming."Start The Project Conversation
