Florida, Virginia and South Carolina are states that see plenty of sun — and few homes with solar panels.

A recent Los Angeles Times article pointed out that the states with the most sun are also states where energy industries — from coal to electric — feel the most threatened and, as a result, increase lobbying efforts for laws that make it difficult for individuals to harvest solar energy.

Oklahoma and Arizona have both passed anti-solar bills this year. The bills allow utility companies to charge fees for customers who buy, install and operate their own solar panels. Proponents of the bills argue that utility companies are not compensated by solar-panel owners for the cost of maintaining infrastructure, but the only cost is transferring extra energy that solar-owners don’t use back to the utility’s main grid. That’s energy that utility companies normally pay solar-panel owners in the majority of states where net metering laws have been enacted.

Energy tycoons like the Koch brothers, who have made fortunes in the oil and gas game, have backed both the bill in Arizona and in Oklahoma as well as other efforts to dismantle the growing solar industry in states where consumers could benefit.
