Reliance on Gas Power Plants Fuels Inequity

Union of Concerned Scientists

Most notable of these polluting emissions are nitrogen oxides (NOx). But studies show that at least 80 to 90% of the US grid could be reliably served with renewable energy and there is limited to zero need for new gas plants for reliability. It indeed accounts for 40% of the electricity currently generated for the grid.
