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.

After the destruction inflicted across the Caribbean by hurricanes Harvey, Irma, and Maria, renewable energy advocates are calling for a rethink of the region’s devastated power systems. Rather than simply rebuilding grids that delivered mostly diesel generation via damage-prone overhead power lines, renewables advocates argue that the island grids should leapfrog into the future by interconnecting hundreds or thousands of self-sufficient solar microgrids.
“Puerto Rico will lead the way for the new generation of clean energy infrastructure. The world will follow,” asserted John Berger, CEO for Houston-based solar developer Sunnova Energy in a tweet before meeting in San Juan with Puerto Rico Governor Ricardo Rosselló this week. Rosselló appears to be on board, inviting Elon Musk via tweet to use Puerto Rico as a “flagship project” to “show the world the power and scalability” of Tesla’s technologies, which include photovoltaic (PV) rooftops and Powerwall battery systems.
Some power system experts, however, say the solar-plus-batteries vision may be oversold. They say that the pressing need to restore power, plus equipment costs and other practical considerations, call for sustained reliance on centralized grids and fossil fuels in the Caribbean. “They need to recover from the storm. Unfortunately I think the quickest way to do that is to go back to how things were before,” says Brad Rockwell, power supply manager for the Kauaʻi Island Utility Cooperative that operates one of the most renewable-heavy grids in the U.S. Continue reading

It’s moving day at the Legislative Assembly of British Columbia on a sunny summer morning in Victoria, Canada, and climate scientist-turned politician Andrew Weaver is battling to retain an expansive leather sofa for his new basement office. Just a few weeks earlier, in May 2017, thousands of people in and around Victoria cast their votes for the British Columbia Green Party, which Weaver leads, growing the caucus from his one lonely seat to three. The wider of the office’s sofas, he explains, will be crucial during long nights of debate and voting. “This is the one you can sleep on. And we need that.”
Three seats in an 87-seat legislature might sound modest, but it’s enough to make Weaver — a professor at the University of Victoria — into a political kingmaker. The incumbent Liberal Party and the opposition New Democratic Party (NDP) each garnered fewer than half of the seats, giving Weaver’s Green Party the balance of power. Weaver exercised his new-found influence in the weeks after the election to remove Christy Clark, the Liberal premier of British Columbia, who had championed fossil fuels and neglected climate policy. He negotiated climate-friendly terms with the NDP to install John Horgan as the party’s first premier in 16 years.
Weaver is an internationally recognized pioneer of models that represent Earth’s physical systems at a modest resolution, facilitating the simulation of climate over tens of thousands of years. His ascent from academic to political power broker is a far cry from the attacks on climate scientists that are under way in the United States. But there are US researchers who dare to dream that they too can tilt the political balance. In fact, dozens have declared the intent to run for local, state or national office, promising to reverse the dismissal of climate change and other anti-science positions espoused by US President Donald Trump’s administration and other Republican Party leaders.

The world’s first wind farm employing floating turbines is taking shape 25 kilometers off the Scottish coast and expected to begin operating by the end of this year. New research by atmospheric scientists at the Carnegie Institution for Science in Stanford, Calif. suggests that the ultimate destination for such floating wind farms could be hundreds of kilometers out in the open ocean. The simulations, published today in the Proceedings of the National Academy of Sciences, show that winds over the open ocean have far greater staying power than those over land.
Wind power generation is obviously contingent on how fast and how often winds blow. But only over the past decade have scientists and wind farm developers recognized that the winds measured prior to erecting turbines may not endure. For one thing, dense arrays of wind turbines act as a drag on the wind, depleting local or even regional wind resources. Continue reading

The sweeping multi-year assessments produced by the Intergovernmental Panel on Climate Change set the gold standard for global scientific consensus on how humanity is altering Earth’s climate, and how to anticipate and minimize those changes. Some top climate scientists, however, are reviving a harsh critique of the IPCC’s assessment process, saying that it takes too long and that the delay could actually be creating an excuse for political inaction.
That process is moving forward this week with little sign of changing as scientists and government officials meet in Montréal to nail down a detailed blueprint for the sixth assessment since the IPCC’s creation in 1988. On Wednesday, IPCC Chair Hoesung Lee called the meeting the “most important” in the production cycle for what will become IPCC Sixth Assessment Report—a cycle that began in 2015 and will not conclude until 2022.
That seven-year schedule is simply unacceptable for a document that is “relied on by countless decision makers around the world every day,” said Katharine Hayhoe, an atmospheric scientist and co-director of the Climate Science Center at Texas Tech …
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
U.S. President Donald Trump called health insurance an “unbelievably complex subject” when Congress was debating health care in February. “Nobody knew health care could be so complicated,” said Trump as Republicans in Congress struggled to find consensus on how to repeal and replace the Affordable Care Act. Given developments in Washington, D.C., over the past week, he could soon be issuing similar tweets about unimagined intricacies in energy policy—intricacies with critical implications for technology developers.
Last week’s main affair in Washington, of course, was Trump’s firing of FBI director James Comey, and the ensuing ‘political firestorm’. But two big energy issues were also playing out, exposing policy rifts among Republicans—cracks that that could ultimately shift the course of U.S. and global policy. Continue reading
