The two probable major-party U.S. presidential candidates hold very different views on energy and climate. One intends to focus on expanding and developing America’s fossil-fuel industries, while the other plans to grow renewable energy and promote efficiency. Can you guess who’s who? Fossil vs. Renewable Donald Trump, the presumed Republican nominee, presented his “America-First Energy […]

The average capacity factor for U.S. natural gas–fired combined cycle power plants (CCPPs) exceeded that for coal-fired plants in 2015 for the first time since the Energy Information Administration (EIA) has been keeping records, the agency noted on April 4. Gas generation exceeded coal generation for most of 2015, though coal ended slightly ahead for […]

In a joint report issued April 5, a group of California agencies and utilities said that if the Aliso Canyon natural gas storage facility north of Los Angeles cannot be returned to service after a major leak this past winter, repeated gas curtailments could occur this summer, leading to significant loss of generating capacity in Southern […]

The Energy Information Administration (EIA) said in its March 8 Short-Term Energy Outlook that natural gas would supply the largest share of U.S. electricity in 2016, continuing its rise against coal. EIA data from 2015 showed that gas and coal pulled into a near-tie on the year, with coal generating 1,356 TWh, for a 33.2% […]

Battered by stubbornly low natural gas prices and regulatory headwinds, coal-fired generation fell into a near-tie with natural gas in 2015, according to data released on Feb. 26 by the Energy Information Administration (EIA). For all of 2015, coal generated 1,356 TWh, while gas-fired generation produced 1,335 TWh, giving coal a slight 33.2% to 32.7% […]

New reports released this week see big growth in renewables from the recently extended federal tax credits, but big uncertainty due to the possible end of the Clean Power Plan (CPP). New York-based consulting firm Rhodium Group says investment plans in the power sector will be radically different if the Clean Power Plan doesn’t happen. […]

Use of natural gas for power generation in the U.S. is skyrocketing. From 2005 to 2015, the share of energy produced from gas has increased over 80%, with gas now comprising about 35% of the fuel mix. This

Florida regulators on Jan. 5 approved the 1,600-MW Okeechobee Clean Energy Center under development by NextEra Energy subsidiary Florida Power & Light (FPL) near Vero Beach. The plant will be the fifth advanced combined cycle power plant FPL has commissioned since 2009. The three-unit Okeechobee plant will join the 1,335-MW 3,750-MW [Ed.-Corrected 1/14/16] West County […]

China Makes Nuclear Export Gains in Argentina, Romania. As it boosts its domestic nuclear power capacity, China is also snapping up lucrative contracts to build new reactors abroad. This November, China

The near-simultaneous surge in U.S. natural gas production and recent enactment of environmental regulations will usher U.S. power supply from reliance on coal to increased usage of natural gas and renewables

Levelized Cost of Electricity

Coal has been the dominant source of electricity in the U.S. power mix for more than a century, but that may be coming to an end sooner than expected. For only the second time ever, but also the second time this year, gas generated more electricity in the U.S. than coal. According to statistics from […]

Russia and Vietnam Ink Deal for First Ninh Thuan Nuclear Unit. Russia’s nuclear group Rosatom and Vietnam’s state-owned power company Electricity of Vietnam (EVN) on July 30 signed a general framework

King Coal has lost his crown—at least temporarily. Electricity generation data from the Energy Information Administration (EIA) for April 2015 showed the U.S. generated 92.5 TWh from natural gas and 88.8 TWh from coal, the first time the nation has gotten the largest share of its power from anything other than coal. That represents a […]

The U.S. Environmental Protection Agency (EPA) on June 4 released a draft assessment of the potential impacts of hydraulic fracturing on the nation’s water supplies, concluding that there was no evidence of widespread impacts but conceding that data on the subject is limited. The assessment, conducted at the request of Congress, follows water used for […]

Electricity generation from existing coal-fired power plants will increase from 2012 levels through 2025, according to the Reference case presented in the U.S. Energy Information Administration’s Annual Energy Outlook 2015, released on April 14. In addition to the Reference case, five alternative cases—Low and High Economic Growth cases, Low and High Oil Price cases, and […]

A Gallup poll completed last month found that only 32% of adults in the U.S. worry a “great deal” about global warming or climate change, while 45% worry “only a little” or “not at all.” The survey was taken via telephone interviews conducted during the first week of March using a random sample of 1,025 […]

Düsseldorf, Germany–based energy supplier E.ON announced on Jan. 12 that it would sell its Italian coal and gas generation assets to Energetický a Průmyslový Holding (EPH), a Czech energy company. E.ON has been looking for a suitor for the Italian operations since at least Nov. 30 when it announced it was embarking on a new […]

A sustained Arctic blast composed of freezing rain, record snowfalls, and high winds hit 22 states, from Mexico to New England in early February 2011. The extreme weather severely affected the power generation

The Tennessee Valley Authority (TVA) is poised to decide on the fate of a coal-fired power plant in Tennessee.  At its next meeting on Aug. 21, the TVA board will likely choose to retire three existing coal-fired units at the Allen Fossil Plant in Shelby County, Tenn., by December 2018 and replace them with a […]

Many utilities have taken advantage of relatively low-cost natural gas to address environmental pressures and upgrade their power generation portfolio in one of three distinct ways—replace, repower, or

Gas Power Reciprocating gas engines find work in multiple power generation applications, from providing fast-start backup generating capacity for intermittent renewable resources to offering scalable and

Pressures on competitive power markets have fueled substantial declines in plant valuations over the past five years, with coal plants taking the brunt of the damage. That’s the conclusion of a new report from financial services firm Fitch Ratings released on Wednesday. The report, which calculated the net present value of plants across the country […]

U.S. states vary widely on how they are regulating the booming business of producing natural gas from shale formations, according to a study released this summer by the Washington environmental think tank Resources for the Future (RFF). “As the shale gas boom has taken off,” says RFF, “states have updated their regulations, each with varying […]

The revolution that has toppled coal from the top of the generating queue in the U.S. has not reached the rest of the world, according to the “BP Statistical Review of World Energy.” While natural gas may have supplanted coal as king of the hill in the U.S. electric generating mix, the solid mineral—geographically the […]

Much recent debate about shale gas recovery through horizontal drilling and hydraulic fracturing has focused on methane emissions from shale gas wells. The general take on this topic is that methane (the remarkably simple molecule CH4) is a greenhouse gas “20 times” or “25 times,” or some other number, more “potent” than carbon dioxide, the […]

The shale gas revolution has so far been a U.S. phenomenon. But hydrocarbon-containing Devonian shale formations are far from a U.S. or even North American phenomenon. Geologic forces didn’t follow political boundaries in the Devonian period 400 million to 300 million years ago. Indeed, the continents then were not where they are today by large […]

If you’ve been paying attention to energy issues in the media lately, you may have encountered a curious narrative that’s starting to gain traction among supporters of renewable energy. Namely, that the core problem with wind and solar photovoltaic (PV) generation, which is matching moment-to-moment demand with the intermittency wind and sunlight, isn’t really a […]
