I Fully Converted a Home to Electricity. Here’s How It Worked — and What It Cost
by Barry Cinnamon for Green Tech Media
Currently available solar, battery and heat pump technology means every building under two stories with a sunny roof can be a net generator of energy. — essentially carbon-negative. Moreover, with grid-connected batteries, buildings can easily provide the resiliency that our grid needs during power shortages and blackouts.
Altruism aside, generation is less expensive than conservation for existing buildings. It is more cost-effective to add solar and storage than to improve the efficiency of the building shell or to replace existing HVAC equipment prior to its end of life with new high-efficiency equipment.
