What Trump’s ‘Energy Week’ policies actually mean

Donald TrumpThe White House declared this past week "Energy Week" and offered up a few key points on which the Trump administration plans to focus to unleash what it calls a new American dominance in energy. However, neither the initiatives nor the proposed policy changes hone in on where the world is heading: renewable energy, free of fossil fuels. Instead...

Soaring growth of solar power demonstrated in one chart

Photovoltaic solar power field at Volkswagen plant in Chattanooga, TennesseeSometimes a picture is truly worth a thousand words. In the case of the rapidly rising rate of solar generation for electricity, numerous forecasts by internationally respected bodies have proven woefully conservative. The image in the tweet below, created by Auke Hoestra at the Technical University of Eindhoven, in The Netherlands, shows it...

Clean energy provides far more U.S. jobs than fossil fuels: analysis

Photovoltaic solar power field at Volkswagen plant in Chattanooga, TennesseeYesterday, U.S. president Donald J. Trump signed an executive order to begin the process of rolling back pretty much every vestige of U.S. efforts to address climate change. In both his campaigning and since his inauguration, Trump has claimed that his government and its actions focus on creating or bringing back jobs for working-class Americans...

Solar power hits new U.S. heights: utility use exceeds home panels

Photovoltaic solar power field at Volkswagen plant in Chattanooga, TennesseeNo matter how you measure it, 2016 was a major year for solar energy. More solar-generating capacity was added last year than either natural gas or wind, according to the U.S. Department of Energy. A study by investment bank and research firm Lazard found that utility-scale solar has now become the single cheapest form of unsubsidized electricity...

When lauding renewables, look at utilization, not just capacity

Photovoltaic solar power field at Volkswagen plant in Chattanooga, TennesseeThe news on the renewable energy front continues to be good, with the costs of wind and solar generation falling steadily. By some measures, large-scale renewable energy is now cost-competitive (or close) with the most efficient natural-gas electric plants. Moreover, the amounts of clean generating capacity installed continue to rise, both in...

More solar energy was added in 2016 than natural gas or wind

Photovoltaic solar power field at Volkswagen plant in Chattanooga, TennesseeRenewable-energy growth has accelerated in 2016, but this may go down as a milestone year for one renewable-energy source in particular. Together, all renewable-energy sources are expected to account for 8 percent of U.S. electricity-generation capacity in 2017, according to the Department of Energy, and solar energy is responsible for most of...

Renewable energy to hit 9 percent of U.S. total in 2017

Photovoltaic solar power field at Volkswagen plant in Chattanooga, TennesseeU.S. renewable-energy generating capacity is not only growing, but it is beginning to erode coal's share of the electricity-generating mix, according to new data from the U.S. Department of Energy (DOE). The agency predicts renewable energy—particularly solar power—to continue growing. At the same time, a combination of renewable...

Coal in China: huge problem for clean power, climate efforts

Coal, by Flicker user oatsy40 (Used Under CC License)Over the past few years, China has made impressive strides in renewable-energy investment. The promotion of renewable energy will only become more important as China works to meet its commitments under the recently-ratified Paris climate agreement. But the country's reliance on coal for electricity generation still poses a huge problem for these...

Hydro-power reservoirs emit methane, a greenhouse gas: no free lunch?

Hoover Dam by Flickr user Airwolfhound (Used under CC License)The energy sources used to generate grid electricity can be a major source of greenhouse-gas emissions, and thus they affect the environmental impact of electric cars. The cleaner the electricity used to charge an electric car, the cleaner that car becomes in operation. And among potential energy sources, hydroelectric power from dams would seem...
