Both the industry and government are betting that a quick takeoff in electric-car sales will drive down the battery prices
“That was the bet for solar panels, too. Thats why every roof in America is covered with cheap solar panels today.”
The cost of solar panels actually has decreased (especially when you factor in dollar inflation), but not to the degree that most consumer electronics have. I don’t see battery prices dropping as fast. I have been studying the economics of photovoltaics for an off-the-grid cabin. Batteries unfortunately constitute half the cost and won’t last long enough to ever pay for themselves, whereas the panels themselves can.

To an extent. But not to nearly the extent necessary to make them economic. I’d like to have them on my roof. But the cost-benefit is still way out of whack.
Thirty years of subsidies have not made much of a dent. Which is, of course, why subsidies. Were there an economic scale-up where someone could make a lot of money on mass-produced solar panels, the market wouldn’t need the help.
