Variable resources such as wind and solar power can provide up to about half of U.S. electricity, with the remaining 30 percent from other renewable sources.
Increasing renewable to supply 80 percent of U.S. electricity does not, however, limit energy choices to one specific pathway. Rather, the NREL study shows that a range of renewable energy scenarios provide the nation with multiple pathways to reach this goal.
Regardless of whether its wind or solar-powered, renewable energy will always be cleaner than fossil energy, which pollutes the air, water, and soil, negatively impacting health, agriculture and natural resources. And, it’s getting cheaper. These factors make renewable energy vitally important – especially to people who depend on the Earth to make a living.
