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 →
NASA’s telescope on DSCOVR snapped a solar eclipse over South America in February
Al Gore didn’t really claim to invent the Internet in 1999, but he did champion a NASA mission that installed a deep space webcam pointed at Earth in 2015. And yesterday President Trump put a bullseye on that mission. Or, rather, on part of it. Trump’s 2018 budget blueprint asks Congress to defund the Earth-facing instruments on the Deep Space Climate Observatory (DSCOVR). Its sensors tracking magnetic storms emanating from the Sun would keep doing their jobs.
Selectively deep-sixing well-functioning instruments on a satellite 1.5 million kilometers from Earth is one of the stranger entries in President Trump’s first pass at a budget request. But it fits a pattern: Throughout the document programs aimed at comprehending or addressing climate change take deep cuts, even where there is no obvious fiscal justification. Continue reading →
President-elect Donald Trump is a self-declared climate-change denier who, on the campaign trail, criticized solar power as “very, very expensive” and said wind power was bad for the environment because it was “killing all the eagles.” He also vowed to eliminate all federal action on climate change, including the Clean Power Plan, President Obama’s emissions reduction program for the power sector.
So how will renewable-energy businesses fare under the new regime?
Trump’s rhetoric has had renewable-energy stocks gyrating since the election. But the impact could be far less drastic than many worst-case scenarios. “At the end of the day what Trump says and what is actually implemented are two completely different things,” says Yuan-Sheng Yu, an energy analyst with Lux Research …
Synthetic inertia is achieved by reprogramming power inverters attached to wind turbines so that they emulate the behavior of synchronized spinning masses.
Montréal-based Hydro-Québec TransÉnergie, which was the first grid operator to mandate this capability from wind farms, will be sharing some of its first data on how Québec’s grid is responding to disruptive events such as powerline and power plant outages. “We have had a couple of events quite recently and have been able to see how much the inertia from the wind power plants was working,” says Noël Aubut, professional engineer for transmission system planning at Hydro-Québec.

Electrification is associated with a seemingly endless list of social and economic goods. Nations that use more power tend to have increased income levels and educational attainment and lower risk of infant mortality, to name but a few. So I was baffled to stumble across a pair of economic analyses on electrification in India and Kenya, posted last month, that cast serious doubt on what has long assumed to be a causal link between the glow of electricity and rural development.
“It is difficult to find evidence in the data that electrification is dramatically transforming rural India,” concludes Fiona Burlig, a fourth-year UC Berkeley doctoral student in agricultural and resource economics who coauthored the India study. “In the medium term, rural electrification just doesn’t appear to be a silver bullet for development.” 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 →
But, upsetting as any killing of birds is, avian mortality is a downside common to many modern human creations—including buildings, highways, and powerlines. The best data on bird mortality at Ivanpah, macabre as it might be, shows the death rate to be small and likely of little ecological significance.
Meanwhile, operational adjustments at both Ivanpah and Crescent Dunes are pushing avian impacts even further below levels that could threaten local bird populations. “The data does support a low level of avian mortalities and hopefully, through adaptive management and deterrence, it will go even lower,” says Magdalena Rodriguez, a senior environmental scientist with the California Department of Fish and Wildlife.
