There has been a strong push to promote increased investments in new nuclear power as a strategy to decarbonize economies, especially in the European Union (EU) and the United States (US). The evidence base for these initiatives is poor. Investments in new nuclear power plants are bad for the climate due to high costs and long construction times. Given the urgency of climate change mitigation, which requires reducing emissions from the EU electricity grid to almost zero in the 2030s (Pietzcker et al.1), preference should be given to the cheapest technology that can be deployed fastest. On both costs and speed, renewable energy sources beat nuclear. Every euro invested in new nuclear plants thus delays decarbonization compared to investments in renewable power. In a decarbonizing world, delays increase CO2 emissions. Our thoughts focus on new nuclear power plants (not phasing out existing plants) in the US and Europe. In Europe, new nuclear power plants are planned or seriously discussed in France, Czechia, Hu

Several nations plan to build new coal power plants, with China alone approving nearly 100 gigawatts. Each gigawatt is the equivalent of installing more than 3 million solar panels.

Climate change is reducing output and raising safety concerns at nuclear facilities from France to the US. But experts say adapting is possible—and necessary.

As China's record heatwave starts to subside, farmers are assessing the damage caused by a prolonged drought and the government is urging them to replant or switch crops where they can.

The U.N. nuclear chief warned that Europe’s largest nuclear power plant in Ukraine “is completely out of control” and issued an urgent plea to Russia and Ukraine to quickly allow experts to visit the sprawling complex to stabilize the situation and avoid a nuclear accident. Rafael Grossi, director general of the International Atomic Energy Agency, said in an interview Tuesday with The Associated Press that the situation is getting more perilous every day at the Zaporizhzhia plant in the southeastern city of Enerhodar, which Russian troops seized in early March, soon after their Feb. 24. invasion of Ukraine. “Every principle of nuclear safety has been violated” at the plant, he said. “What is at stake is extremely serious and extremely grave and dangerous.”

A coal-fired power plant that had been mothballed has become the first of its kind to be put back on to the network in Germany, as debate rages over how Europe’s largest economy will cope without Russian gas. The facility in Lower Saxony, which is owned by the Czech energy company EGH, has received emergency permission to run until April in an attempt to boost energy production.

Coal plants will be reactivated if Russian President Vladimir Putin threatens a gas cutoff, a government official said. That would trigger the second of a three-stage Germany’s gas emergency plan.

Humankind is revealed as simultaneously insignificant and utterly dominant in the grand scheme of life on Earth by a groundbreaking new assessment of all life on the planet. The world’s 7.6 billion people represent just 0.01% of all living things, according to the study. Yet since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds.

Our new research suggests that temporary nature-based carbon storage can help achieve our climate goals. However, the most tangible effect — a decrease in peak warming — would only occur if we also eliminate fossil fuel emissions.

When the lights went out at Chornobyl Nuclear Power Plant on 9 March, the Russian soldiers holding Ukrainian workers at gunpoint became the least of Anatolii Nosovskyi’s worries. More urgent was the possibility of a radiation accident at the decommissioned plant. If the plant’s emergency generators ran out of fuel, the ventilators that keep explosive hydrogen gas from building up inside a spent nuclear fuel repository would quit working, says Nosovskyi, director of the Institute for Safety Problems of Nuclear Power Plants (ISPNPP) in Kyiv. So would sensors and automated systems to suppress radioactive dust inside a concrete “sarcophagus” that holds the unsettled remains of Chornobyl’s Unit Four reactor, which melted down in the infamous 1986 accident.

Oil companies love to tell the world about the super cool technologies that have that will allow us to keep burning fossil fuels without cooking the climate. But those technologies are largely bullshit.

CCS - Carbon Capture and Storage: A research brief published by the Institute for Energy Economics and Financial Analysis (IEEFA) concludes that the abrupt recent shutdown of the Petra Nova coal-fired carbon capture plant in Texas should be seen as a strong signal for investors to avoid such projects.

Pledges to plant trees fall from politicians’ lips like leaves in the autumn, especially during elections and climate summits. Yet ambitious government planting targets are likely to be missed because there are not enough trees or people to plant them, leading forestry figures have warned.

Thanks to Victorian street planners, many British streets were designed to be full of big trees and, with 84% of the population living in urban areas, most people are more likely to encounter trees in the streets than they are in forests.

Operators say the Orca plant can suck 4,000 tonnes of CO2 out of the air every year and inject it deep into the ground to be mineralised

Lake Oroville’s water level has fallen so low that on Thursday, for the first time since the dam was built in 1967, its power plant was shut down because there is no longer enough water to spin the turbines and generate electricity.Last Friday, hoping to avert any more power shutdowns, Gov. Gavin Newsom issued an emergency order that temporarily waives some air pollution rules to allow natural gas power plants to generate more electricity and pays industries $2 a kilowatt-hour to reduce their electricity use during heat waves.
