Other economists pointed out Biden’s decision may have the reverse effect in his fight against climate change.

“There’s only so much [Europe] can do with renewables because battery technology has its limitations currently,” Philip Rossetti with R Street Institute told DVJournal. “They’re going to need coal, which is what you saw Germany doing, ramping up a lot of coal production.”

Producers have been able to cut pollutants from U.S. coal plants through carbon capturing. That technology is still under development. Plus, China and India use coal-fueled power plants the most due to coal’s cheapness and availability.

As for relying on social media influencers to make climate policy, Rossetti quipped, “Policy decisions need to be focused on what credible analysis shows delivers the best outcomes for everyone, and not just what’s popular in some circles.”
