In a new report, the International Energy Agency (IEA) says solar is now the cheapest form of electricity for utility companies to build. That's thanks to risk-reducing financial policies around the world, the agency says, and it applies to locations with both the most favorable policies and the easiest access to financing. The report underlines how important these policies are to encouraging development of renewables and other environmentally forward technologies. Carbon Brief (CB) summarizes the annual report with a lot of key details. The World Energy Outlook 2020 "offers four 'pathways' to 2040, all of which see a major rise in renewables," CB says. "The IEA's main scenario has 43 [percent] more solar output by 2040 than it expected in 2018, partly due to detailed new analysis showing that solar power is 20 [to] 50 [percent] cheaper than thought." The calculation depends on financing figures compared with the amount of output for solar projects. That means that at the same time panel technology gets more efficient and prices for basic panels continue to fall, investors are getting better and better financing deals. So the statistic "20 to 50 percent cheaper" is based on a calculus of companies building solar projects, not something that has throughput for consumers or even solar homeowners. But it's still a big deal, because the cost to build power plants is a major part of why so much of the world has stuck with coal and gas power.
