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.

Relations between the United States and Mexico are strained at the national level, with President Donald Trump pushing his promised border control wall and demanding a U.S.-favored rewrite of the North American Free Trade Agreement (NAFTA). But Mexico and the southwestern states have continued working towards an international agenda for electricity, and regional players are talking up a first set of projects due to be completed before Trump’s term is up — projects that put the region on a path to a far more electrically-porous border.
These projects include a trio of new crossborder links between California, Arizona and Mexico to be completed in the next three years. They also include grid studies, revised market rules, and new power lines within Mexico that could rapidly expand flows over all of the U.S.-Mexico interties. “The proposition right now is fairly small because the interconnections are small. But that’s going to change,” says Carl Zichella, director for Western transmission at the Natural Resources Defense Council. Continue reading
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.

For all of the excitement about using solar power to bring electricity to the more than 1 billion rural poor worldwide living without it, big picture trends provide a sobering reality check. In spite of innovative off-grid technology and business plans and high profile initiatives aiming to power remote villages in subsaharan Africa, for example, electrification there is still falling behind population growth. In 2009 there were 585 million people in sub-Saharan Africa without power, and five years later that figure had risen to 632 million, according to the latest International Energy Agency (IEA) statistics.
A first-of-its-kind deep-dive analysis of the flow of capital, released by the United Nation’s Sustainable Energy for All (SEforALL) program today, shows that off-grid systems simply are not getting the support they deserve. “This research shows that only 1 percent of financing for electrification is going into this very promising and dynamic energy solution,” says SEforALL CEO Rachel Kyte, who says the findings are “a wake up call” for the international community.

“Public trust is at stake here, folks.” That’s how South Carolina’s top power industry regulator described the gravity yesterday of local utilities’ decision to walk away from a pair of partially-built nuclear reactors, according to Charleston’s Post and Courier newspaper. Public Service Commission chairman Swain Whitfield added that the reactors’ cancellation after $9 billion of investment — more than the state’s annual budget — “is going to shatter lives, hopes and dreams” in South Carolina.
South Carolina-based Santee Cooper and SCANA’s abandonment of their pair of new reactors, announced on Monday, also have broader ramifications for the nuclear industry’s self-declared “nuclear renaissance.” In March the cost overruns and delays afflicting this project and a sister project in Georgia drove the reactor designer and builder Westinghouse Electric Co. into bankruptcy. Cost overruns and political concerns are also squeezing nuclear suppliers from France, South Korea, and Russia. Continue reading
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
