As more solar and wind come onto the grid, prices go down but new questions come up
https://phys.org/news/2018-05-solar-grid-prices.html
In particular, our study shows how solar and wind tend to lower energy prices, but they add new complexity for operating the grid, which has big implications for regulators. For consumers, this research is a reminder that making the electricity grid cleaner with wind and solar is an evolving process that requires significant changes to how the power grid is currently run—but one that offers large opportunities, if we as a country can become more flexible when we use electricity.
Previous analyses, including our own, showed that solar and wind already impact wholesale electricity markets, leading to more fluctuations in energy prices.
