The Future of Renewable Energy

As constant pollution and the looming effects of climate change make it increasingly urgent to phase out fossil fuels, we are turning to renewable energy to replace our current sources. As of 2019, 17% of U.S. power generation comes from renewable energy, a combination of various types including wind, hydroelectricity, solar, and geothermal. Now that plans are being made to invest in and increase usage of renewable energy, many people ask which source is the best. Which is the cheapest, the most efficient, the most environmentally friendly? However, there is not a clear answer to this question, as each renewable has its own unique pros and cons and may be better in some areas than others.
