We keep this chart up to date, and you can read the details of our 2006-2007 energy audit, where we document our reduction process. We went from 2500 kWh a month to a twelve month average of 879 kWh. People often ask if we have solar power. We don't. We use a solar hot water heater, which shaves a lot off our monthly bill. At this time, installing a solar power system would cost roughly $35,000, and would take over 40 years to pay for itself. If we ever own an electric car, it may become worth it, but for now a total PV system is cost prohibitive. |
