Big energy hugely underestimates electric cars, renewable power

2016 BMW i3Mass adoption of electric cars and renewable energy could significantly decrease global consumption of fossil fuels. But does the established energy industry view these new developments as a threat? In a recent report, ExxonMobil said coal could continue to provide the majority of the world's electricity-generation capacity in 2040, and that...

3 California battery storage sites come online, one from Tesla

Tesla and SolarCity energy storage array on Ta'u, American SamoaLong a leader in the push to reduce vehicle emissions and switch to renewable energy, California marks another milestone this week. The last of three battery energy-storage sites will come online in Southern California, providing storage and buffering for unpredictable renewable energy. Together, the three sites add up to capacity equal to fully...

Exxon says coal will endure; other analyses beg to differ

Coal, by Flicker user oatsy40 (Used Under CC License)Renewable energy sources may eventually render fossil fuels irrelevant in energy generation, but when will the switch between the two energy sources occur? It's a question that fosters much debate among policymakers, environmental advocates, and financial analysts. For its part, ExxonMobil believes fossil fuels—notably including...

Energy storage batteries face biggest test in California

Tesla and SolarCity energy storage array on Ta'u, American SamoaFrom the perspective of both renewable-energy advocates and electric utilities, grid-scale energy storage offers many potential benefits. By storing energy in battery packs for later use, energy storage can make intermittent renewable sources like solar and wind into more reliable forms of power. It also helps utilities "balance" the gird by...

First carbon-capture power plants come on line this year

Coal, by Flicker user oatsy40 (Used Under CC License)For electric utilities eager to hang onto their existing coal-fired power plants, carbon-capture technology must offer an exciting chance at salvation. As the name says, carbon capture retains and stores the emissions produced by coal power plants in particular, in theory mitigating some of their environmental impact. Power plants equipped with...

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...

UK moves ahead on lower-carbon power to end coal use by 2025

Coal, by Flicker user oatsy40 (Used Under CC License)The United Kingdom is increasing its use of low-carbon energy sources as it moves to phase out coal-fired power plants altogether by 2025. Renewable-energy sources such as wind and solar, combined with nuclear power and generating plants fired with renewable wood pellets, are displacing fossil fuels in the country's electricity-generation mix...

Scotland shows path toward boosting renewable energy in a big way

Nissan Leaf in ScotlandScotland isn't known for having the most pleasant weather. But its persistent winds make the country a great place for renewable energy. Over the past few years, officials have overseen the construction of numerous wind turbines, in hopes of turning Scotland's weather into a useful resource. CHECK OUT: What Country Powered Itself Entirely On...

Smallest state poses big question: natural gas or renewable energy?

wind farmThe smallest U.S. state now faces a big question on energy policy. Rhode Island is in the midst of deciding whether to continue getting a large portion of energy from fossil fuels, or to switch to renewable energy. Those options are represented by two competing projects: a large natural-gas power plant, and an offshore wind farm. DON'T MISS: Dirty...

DoE energy-loan program (notorious for Solyndra) now turning a profit

Photovoltaic solar power field at Volkswagen plant in Chattanooga, TennesseeThe U.S. Department of Energy (DOE) loan program that became a lightning rod during the 2012 presidential election is now turning a profit. The program became infamous for backing solar company Solyndra, which later went bankrupt. Three years after Soyndra's failure, though, the program is now in the black.

Carbon emissions from U.S. power generation fall to 25-year low

Wind farm, by Flickr user Patrick Finnegan (Used under CC License)While automakers work to meet stricter carbon-emissions standards, another sector of the U.S. economy has already made notable progress in reducing ts emissions. Carbon-dioxide (CO2) emissions from electricity generation during the first six months of 2016 were the lowest since 1991, according to the U.S. Energy Information Administration (EIA)...

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...
