Fossil fuel proponents may claim that even renewables or “clean energy” have harmful impacts on the environment to justify continued drilling and mining — but that’s not the whole truth. Here’s the reality — all forms of energy production, and really any form of human development, can have impacts. But renewables like wind and solar are called clean for a reason. Their impacts are many times smaller than those of other energy sources. Scott Tinker’s recent commentary in The Hill arguing the environment damage renewable cause contains outdated and incorrect information about renewable energy.
