Solar and wind keep getting cheaper as the field becomes smarter

As solar and wind energy ramps up in the United States, the industries have gotten better at installing and operating their facilities. This experience can be seen in how the facilities are financed. According to new research, people working in the fields—and adjacent ones—have learned to be more efficient, reducing the overall cost of power. Further, according to Mark Bolinger, a research scientist at Lawrence Berkeley National Laboratory and one of the paper’s authors, this so-called learning rate can be extrapolated into the future, and it spells good news for the two renewable sources of energy.

“The people who operate these turbines naturally get better over time as they do more of it. They get more efficient, and it allows them to lower their costs a bit,” Bolinger told Ars, adding that the same holds true for the workers manufacturing the facilities. “Some of them have been doing it for a really long time… All things being equal, that should lead to a reduction in manufacturing costs.”
