Opinion: Carbon-free energy requires a mix of sources

MAINE SUNDAY TELEGRAM • March 14, 2021

In a March 6 commentary, Sarah Leighton of Sierra Club Maine advocated for the electrification of our heating systems to reduce the use of fossil fuel, which is fine. However, this is the same Sierra Club chapter that is working side by side with the fossil fuel industry to stop New England Clean Energy Connect, which would replace 1,200 megawatts (the capacity of the Seabrook nuclear plant) of fossil fuel-generated electricity. Because of the intermittent power of solar and wind, lithium battery storage and fossil fuel will be required to meet demand. ~ Joe McNeill, Portland
