For the second year in a row, wind and solar accounted for roughly two-thirds of new U.S. generating capacity, while natural gas and nuclear made up most of the rest.
Wave power could account for a quarter or more of U.S. electricity needs if we work to develop its potential around our coastlines, and could also provide other countries with a readily available renewable and free energy source.
Jeremy Martin is a Senior Scientist for the Union of Concerned Scientists’ Clean Vehicles Program, in charge of evaluating biofuels and policy. EarthTalk’s Ethan Goffman interviewed him in Rockville, Maryland, where their discussion ranged from the impact of automobiles to surprising findings regarding corn ethanol to the transportation system of the future…
Nuclear fusion may be the most promising energy source that most of us have never heard of. Scientists first discovered fusion as a potential energy source in the 1930’s and have been quietly working on it ever since. Only recently, given societal pressure to find alternatives to fossil fuels, has fusion started to capture the attention of the media and policymakers—and now researchers are hoping the process can become a key source of safe, clean, reliable energy in the near future.
Dear EarthTalk: What’s the latest in cutting-edge, hyper-efficient solar cells? Are we really moving beyond huge photovoltaic panels anytime soon? —Michael Williams, Hartford, CT Many people still consider environmentalists’ favorite black panels as the cutting edge of renewable energy. However, the burgeoning solar industry has […]
Strong winds up and down the East Coast could power our energy future. Offshore wind is one of the most promising means of supplying clean, steady electricity that doesn’t suffer the intermittency of much renewable energy. On the East Coast, offshore wind is the “largest renewable energy resource that can help make an impactful difference […]
South Africa’s slow uptake of sustainable, renewable energy resources, underlined by its dependency on poorly maintained, fossil-fueled power stations and protracted delays in commissioning two new coal-fired stations, has plunged the country in a series of nationwide blackouts. The move to renewable power, as the government struggled with the principle of loosening its grip on […]
