Prepaid electric bill for life.
Since we have been used to paying electric bills on a monthly basis, most customers don’t realize how expensive electricity is over a long period of time when they see the cost of buying solar power to energize their home. I noticed when consumers buy a clean energy system, all of a sudden they start thinking about energy efficiency although when just paying month to month for electricity from the utility company customers are more wasteful. It seems like when customers become their own producers, they start to appreciate the long term value of electricity. Why do you think people who buy their own clean energy system become more cautious of their electric usage after they install a system?
