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 wide sofa, 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 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 to install a new government under climate-friendly terms. Now US researchers are daring to dream that they too can follow in Weaver’s footsteps, and tilt the political balance. … READ ON AT NATURE.COM
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. Atmospheric scientists at the Carnegie Institution for Science argue that the ultimate destination for such floating power farms could be hundreds of kilometers out in the open ocean. Their 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.
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 deep-dive analysis of capital flows, released today by the UN’s Sustainable Energy for All program, 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 calls the findings “a wake up call” for the international community.

Can you imagine an electric cooler compact enough to fit in your pocket and flexible enough to wear? If not, think again because engineers at the University of California at Los Angeles and SRI International have one working: A 5-millimeter-thick device that is the world’s first solid-state cooler combining practicality, energy efficiency, and high performance. Solid-state cooling has become a highly-competitive field in recent years, as researchers race to develop alternatives to refrigerators and air conditioners that gobble energy and release potent greenhouse gases. In 2014 General Electric heralded a “breakthrough” using materials that heat and cool when moved near and away from magnets, enthusing that its “magnetocaloric” system could be “inside your fridge by the end of the decade.” The comparatively simple working device from UCLA and SRI, reported in today’s issue of the journal Science, may give GE the chills.
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. The production cycle for what will become IPCC Sixth Assessment Report—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.

“Public trust is at stake here, folks.” That’s how South Carolina’s top power industry regulator described the gravity of local utilities’ decision to walk away from a pair of partially-built nuclear reactors, according to Charleston’s Post and Courier. 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.” 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 “Palmetto State’s $9-bn Nuclear Boondoggle”
A battle royale between competing visions for the future of energy blew open today on the pages of a venerable science journal. The conflict pits 21 climate and power system experts against Stanford University civil and environmental engineer Mark Jacobson and his vision of a world fuelled 100 percent by renewable solar, wind, and hydroelectric energy. The criticism of his “wind, water and sun” solution and an unapologetic rebuttal from Jacobson and three Stanford colleagues appear today in the Proceedings of the National Academy of Sciences. In fact, while both sides claim to be objectively weighing the energy options, the arguments and backgrounds of the protagonists belie well-informed affinities for various energy sources (and informed biases against others). As sociologists of science would say, their choice of data and their reading of it reflects hunches, values, and priorities.
