In July 2017, China’s National Energy Administration ordered the plant’s owners to stop construction of two 1,000 megawatt units at the plant; in September 2017 the order was changed to “postpone.” Construction on the two units officially resumed on 28 March 2019.

In tougher times, China falls back on coal – “There’s a deep contradiction in this”

By Stephanie Yang 23 December 2019 BEIJING (The Wall Street Journal) – China’s efforts to wean itself off coal are losing steam, as the world’s biggest carbon emitter is putting economic growth and energy security above its ambitions to be a leader in combating climate change. Coal consumption is back near peak levels after rebounding […]

Apple and Google named in U.S. lawsuit over Congolese child cobalt mining deaths

By Annie Kelly 16 December 2019 (The Guardian) – A landmark legal case has been launched against the world’s largest tech companies by Congolese families who say their children were killed or maimed while mining for cobalt used to power smartphones, laptops and electric cars, the Guardian can reveal. Apple, Google, Dell, Microsoft, and Tesla […]

Radar plots of urban types based on identified factors. For each city we collect information on 64 urban indicators, from which we identify nine dominant factors: metro, bus rapid transit (BRT), bikeshare, development, population, sustainability, congestion, sprawl, and network density (Oke, et al. 2018). We then cluster the 331 cities on these nine factors, producing 12 unique city types Radar plots indicate normalized factor scores (from 0 to 1) averaged for all cities in each type; adapted from Oke, et al. (2018). The “Congested Boomer” type represents rapidly growing megacities with severe congestion problems and low metro availability, particularly in India; notable members are Bangalore, Mumbai, and Delhi.

Why the electric-car revolution may take a lot longer than expected – MIT analysis finds steady declines in battery costs will stall soon

By James Temple 19 November 2019 (Technology Review) – A new report from the MIT Energy Initiative warns that EVs may never reach the same sticker price so long as they rely on lithium-ion batteries, the energy storage technology that powers most of today’s consumer electronics. In fact, it’s likely to take another decade just to eliminate […]

Photo gallery: Inside the Icelandic facility where Bitcoin is mined – Cryptocurrency mining now uses more of Iceland’s electricity than its homes

By Laura Mallonee 3 November 2019 (Wired) – Less than two miles from Iceland’s Reykjavik airport sits a nondescript metal building as monolithic and drab as a commercial poultry barn. There’s a deafening racket inside, too, but it doesn’t come from clucking chickens. Instead, tens of thousands of whirring GPUs perform the complex, exhaustive calculations […]

Wyoming landfill begins burying turbine blades – Burial site “to last hundreds of years”

By Kody Allen 18 September 2019 CASPER, Wyoming (Wyoming News Now) – One wind farm in Glenrock and two from the Saratoga area have partnered with the Casper Regional Landfill to dispose of their old wind turbine blades. More than 900 blades will be brought to the landfill beginning now until the end of next […]

Wind turbines tossed into dump stirs debate on wind power’s dirty downside

By Chris Martin 31 July 2019 (Bloomberg) – Wind turbines may be carbon-free, but they’re not recyclable. A photograph of dozens of giant turbine blades dumped into a Wyoming landfill touched off a debate Wednesday on Twitter about wind power’s environmental drawbacks. The argument may be only beginning. Fiberglass turbine blades — which in some […]

Earth Overshoot Day 2019 is July 29, the earliest ever

OAKLAND, California, 23 July 2019 – On 29 July 2019, humanity will have used nature’s resource budget for the entire year, according to Global Footprint Network, an international sustainability organization that has pioneered the Ecological Footprint. It is Earth Overshoot Day. Its date has moved up two months over the past 20 years to the […]

It is probably too late to stop dangerous global warming – “The hard truth is that we are not on track”

By Sam Arie 17 July 2019 (Financial Times) – Few things should make you as optimistic — or as pessimistic — as the rise of renewable energy. Optimism comes from a new sense of urgency as the UK, Germany, and Spain set record highs for use of wind and solar power, and record lows for […]

Nuclear power, once seen as impervious to global warming, threatened by heat waves – “You need to solve global warming for nuclear plants to survive”

By Alan Neuhauser 1 July 2019 (US News) – There’s a reason nuclear plants are built close to water. Harnessing the enormous power of nuclear fission, plants generate steam, which shoots through pipes to spin a turbine that generates massive amounts of electricity. To keep from getting dangerously hot, the plants suck up surrounding water […]

“Committed” CO2 emissions jeopardize international climate goals – Existing, planned fossil fuel-burning infrastructure must be retired early, replaced – “Without such radical changes, we fear the aspirations of the Paris agreement are already at risk”

IRVINE, California, 1 July 2019 (UCI News) – The nations that have signed agreements to stabilize the global mean temperature by 2050 will fail to meet their goals unless existing fossil fuel-burning infrastructure around the world is retired early, according to a study [pdf] – published today in Nature – by researchers at the University […]
