How is capitalism the problem?

Capitalism is the solution, it’s the cause of this huge deployment of solar.

Market forces have chosen the cheapest cost and that has been deployed. That itself through supply and demand and impacted the price of electricity. This has caused low and even negative prices in the day.

Denholm says that as solar continues to drop in price, installing solar that is curtailed regularly can still be cost-effective. “Throwing away some amount of renewable energy can absolutely make economic sense,” he said.

Those same market forces and causing the huge development of batteries as people can make money buying low selling high in the evening. The issue is that solar is causing excess costs to the grid, as such that cost needs to be recouped or the grid will fail and people won’t have power at all.
