Extreme weather events have knocked both nuclear and coal-fired power plants offline in just the past six months, undercutting the Trump Administration’s argument that subsidizing these aging energy generators is crucial for bolstering grid stability. The latest failure came late last week when Winter Storm Gregory forced a nuclear plant in New England offline, ratcheting up the challenge facing grid operators amidst the “bomb” cyclone’s high winds and freezing temperatures.

U.S. President Donald Trump’s Rose Garden declaration yesterday that he will pull the country out of the Paris Agreement on climate change painted the United States as an economic victim, swindled into an “unfair” deal by the global community. He is right that the world is united: Nearly 200 countries back the 2015 Paris deal, with only Syria, Nicaragua and now the U.S. opting out. But fact checkers had a field day with Trump’s justification: his claim (against all evidence to the contrary) that the treaty imposes “onerous energy restrictions” on the U.S. that would beget “lost jobs, lowered wages, shuttered factories, and vastly diminished economic production.”
Nicaragua opted to stay out because it viewed the treaty’s reliance on voluntary national pledges rather than binding greenhouse gas reduction targets as “a path to failure” that would allow human-caused global warming in this century to surpass the agreed limit of 1.5 to 2 degrees Celsius. Trump said yesterday he would keep the U.S. in the Paris deal only if he can renegotiate it to be weaker still, though his language belied a lack of conviction. “If we can, that’s great. If we can’t, that’s fine,” equivocated Trump.
The President’s retreat from one the great technological challenges of the 21st Century marked a sad day for America’s innovation leaders, and a breaking point for Elon Musk. The tech titan behind such fast-growing engineering powerhouses as Tesla Motors and SpaceX insisted on Tuesday that he had worked mightily, both directly with the President and through his membership on three Presidential economic councils, to convince Trump to stick with Paris. Within minutes of Trump’s speech yesterday, Musk tweeted that he was pulling himself from Team Trump:
Musk had considerable company. A sweeping set of U.S. innovators, mayors, governors, and business leaders spoke up yesterday, vowing to stick with the goals of the Paris Agreement even if the federal government does not. They have another three years to work on Trump’s stance, because the treaty’s rules impose at least a three year wait for a signatory to pull out. Continue reading
President Donald Trump surrounded himself with coal miners at the EPA yesterday as he signed an executive order calling for a clean sweep of all federal policies hindering development of fossil fuel production in the United States. The order’s centerpiece is an instruction to federal agencies to cease defending EPA’s Clean Power Plan and thus, according to Trump’s rhetoric, revive coal-fired power generation and the miners who fuel it.
The electric power sector, however, responded with polite dismissal.
What separates President Trump and some of his top officials from power engineers and utilities? The latter operate in a world governed by science and other measurable forces. Unlike President Trump, scientists, engineers, and executives suffer reputational and financial losses when they invent new forms of logic that are unsupported by evidence. And a world of fallacies underlies the President and his administration’s rejection of climate action. Continue reading
Last month I argued that the primary reason Chinese wind farms underperform versus their U.S.-based counterparts is that China’s grid operators deliberately favor operation of coal-fired power plants. Such curtailment of wind power has both economic and technical roots, and it has raised serious questions about whether China can rely on an expanding role for wind energy. New research published today appears to put those concerns to rest, arguing that wind power in China should still grow dramatically.
The report today in the journal Nature Energy projects that wind energy could affordably meet over one-quarter of China’s projected 2030 electricity demand—up from just 3.3 percent of demand last year.
In fact the researchers, from MIT and Tsinghua University, project that modest improvements to the flexibility of China’s grid would enable wind power to grow a further 17 percent. That, they argue, means that China’s non-fossil resources could grow well beyond the 20 percent level that China pledged to achieve under the Paris Climate Agreement. Continue reading
What do you get when you mix a desert beetle, a pitcher plant, and a cactus? Pick the right parts and you get an extremely slippery surface with an uncanny capacity to condense and collect water, according to research reported today in the journal Nature.
The advance could be a big deal for the energy world because, when it comes to energy efficiency, condensation lies somewhere between a necessary evil and a major drag. Nuclear, coal, and thermal solar power plants, for example, require large heat exchangers to condense the steam exiting from their turbines so that they can raise a new round of hotter steam. For other devices, such as wind turbines and refrigerator coils, condensation is the first step towards energy-sapping ice formation. Continue reading
XPRIZE—the organization behind grand technology challenges such as the race to space won in 2004 by SpaceShipOne and current contests to land a Lunar rover and a Star Trek-style medical tricorder—unveiled a competition today that tackles a more mundane yet critical challenge: transforming carbon dioxide emissions from power plants into saleable products to help slow or reverse climate change. The competition’s $20 million kitty has been raised from major carbon emitters: a coalition of oil and gas producers producing high-carbon oil from Alberta’s oilsands, and New Jersey-based electric utility NRG Energy.

Chinese censors took down a hugely popular documentary on China’s air pollution crisis this past weekend, according to reports by the Wall Street Journal and the New York Times. Under the Dome, a polished, 104-minute report by Chinese broadcast journalist Chai Jing [embedded below], had gone viral after its release last week, attracting several hundred million views in China before censors restricted domestic access to the video and squelched news coverage of it.
The film is a damning account of China’s declining air quality, the sources of its pollution, and the toothlessness of environmental agencies charged with controlling it. It’s a wide-ranging production that tries to explain the price China has paid for its industrialization and wealth generation, as well as a passionate call to action.
For me, the film’s visceral portrayal of contemporary life amidst smog—and the movie’s historic sweep—sparked flashbacks to my own discomfort breathing in Chinese air during visits in 1991, 2005, and 2006.
In 1991, my eyes burned as the aging cruise liner I’d taken over from Japan motored up the Huangpu River, past the petrochemical plants then lining the river’s eastern banks, on its way into Shanghai. But the historic city across the river was clean. Aside from a few buses, it was a city that still moved on pollution-free pedal power, its streets a flood of bicycles. And as I traveled inland for several weeks, the pollution faded further, revealing China’s natural beauty.
When I flew into Shanghai 14 years later to report on China’s rising tide of electric bicycles for IEEE Spectrum, Shanghai itself seemed still cleaner than I’d recalled. While cars and trucks were on the rise, the East-bank industry had been cleared to make way for gleaming skyscrapers.
But China was clearly changing. I visited smaller cities where smog nearly blocked out the sun. Continue reading
