A brief decade held considerable cost-efficiency gains in wind and solar. These sustainable technologies are now more cost-effective than any other power generation technologies in general, according to Lazard. Solar and wind technologies simply make more sense.
Further, this analysis excludes subsidies. Solar and wind aren’t just cost-effective when subsidized – they’re cost-effective when not subsidized despite more than a century of fossil fuel subsidies. Solar and wind have actually gotten so cheap that they are now competing with existing coal and nuclear power plants. In other words, new wind and solar farms can be cheaper than continuing to get power from existing coal and nuclear power plants.
