Bangladesh has installed a million solar power systems, and is installing hundreds of thousands of new ones per year.

"One solar energy system every four minutes" in the US sounds impressive, but it amounts to only some 130,000 a year — far below what we could achieve if policies were set up to encourage it instead of obstructing it.

California electric utilities are trying to obstruct local solar electric generation.

The excuse that the utilities give is incoherent. Suppose someone did get energy from the grid to charge a battery, and sold it back later. If the prices are unvarying, he'd lose money on the deal, because the utility would sell it at a higher price and buy it back at a lower price. Therefore, the systems would be designed to avoid this.

If, however, the price of electricity varies from moment to moment according to usage and availability (which is a recommended practice), people would have an incentive to charge their batteries when electricity is cheap and sell the electricity back to the grid when electricity is expensive. And this is exactly what society needs to reduce the problem of peak demand.
