Researchers combine electricity prices, emissions rates, and weather data to map the changing value of PV at ~10,000 locations across the US. Cost declines are found to have outrun value declines, such that the energy, capacity, health, and climate benefits of PV outweigh utility-scale PV costs at the majority of locations modeled.

When governments need to raise public revenues, they should tax non-renewable resources more than regular commodities according to a dynamic rule. For carbon resources, that means augmenting the carbon tax in a way that further reduces their development and slows down their exploitation, which goes further in the direction of resolving the climate problem.
