All our electric power comes from our solar panels. These panels generate 50kW and during a sunny day we pump excess power into the electric grid, even powering our neighbors. When the sun goes down, we take our power back from the grid. The system is self-sustaining and we have not paid a significant electric bill in years. The solar farm generates no noise, harms no creatures, and really requires no maintenance, other than a wash once a year. No carbon footprint. No fossil fuel usage. Green. Beautiful.
