What would be the next step towards energy independence? Plug a vehicle into the equation. Homeowners could opt to invest in an all electric or hybrid plug in vehicle that can be simultaneously charged over the night with the solar system's excess stored energy. This would save charging time during the day, and would ensure the electric/hybrid vehicle owner that her/his energy is coming from a clean source. Let us know what you think!
