      ‘It could wreak havoc’: Kenya’s nuclear plan casts a shadow over wildlife and tourism hotspot

      news.movim.eu / TheGuardian · Monday, 17 June - 05:00

    Unease and anger are rising over proposals to build country’s first facility on Kilifi coast, home to white sand beaches, coral reefs and mangrove swamps

    Kilifi County’s white sandy beaches have made it one of Kenya’s most popular tourist destinations. Hotels and beach bars line the 165 mile-long (265km) coast ; fishers supply the district’s restaurants with fresh seafood; and visitors spend their days boating, snorkelling around coral reefs or bird watching in dense mangrove forests.

    Soon, this idyllic coastline will host Kenya’s first nuclear plant, as the country, like its east African neighbour Uganda , pushes forward with atomic energy plans.

      Ecuador’s president won’t give up on oil drilling in the Amazon. We plan to stop him – again | Nemonte Nenquimo

      news.movim.eu / TheGuardian · Sunday, 16 June - 13:06 · 1 minute

    This forest is our home, our existence and our children’s future. Politicians who can’t resist selling it for oil cash will feel the strength of the Waorani people

    In 2019 I helped lead a movement that defeated the Ecuadorian government’s plans to auction half a million acres of Waorani territory in the Amazon to oil companies. We showed in court that the government had violated its legal obligation to obtain free, prior and informed consent from Indigenous communities. We won a moral and legal victory on behalf of our ancestral home in that moment – or so we thought. Now, however, Ecuador’s president plans to plough through that legal judgment and recommence oil drilling on nearby Indigenous lands. He obviously hasn’t reckoned with the strength and tenacity of the Waorani people.

    In winning that landmark legal case, we protected pristine rainforest lands, Indigenous autonomy and our planet’s climate from further deforestation. We protected our homes, our children’s future and the forests where I grew up playing with my siblings and pet monkeys, learning to garden and make fresh chicha, and where my people still live today. No more destroying our lives, homes and forests to pump the blood of our ancestors from beneath the soil.

      Will I need to spend a lot insulating my home to get a heat pump?

      news.movim.eu / TheGuardian · Thursday, 13 June - 14:15

    Many people fear the UK’s draughty old properties are too great a challenge for the technology

    Heat pumps could be the single largest step a household can take to reduce their carbon emissions while saving money on their bills. But many in Britain fear that, even though millions of homes across Europe have benefited from the shift away from gas or oil boilers, the UK’s draughty old homes could prove too great a challenge for the technology.

    The concern is unsurprising given that the UK has some of the least energy efficient homes in Europe. A study by the smart home company tado° monitored 80,000 users across Europe to find how quickly properties lose heat when outdoor temperatures fall to zero. It found that UK homes lost on average 3C after five hours without heating, compared with just 1C in Germany and 0.9C in Norway.

      Ugandan oil pipeline protester allegedly beaten as part of ‘alarming crackdown’

      news.movim.eu / TheGuardian · Wednesday, 12 June - 13:02

    Stephen Kwikiriza is one of 11 campaigners against EACOP targeted by authorities in past two weeks, rights group says

    A man campaigning against the controversial $5bn (£4bn) east African crude oil pipeline (EACOP) is recovering in hospital after an alleged beating by the Ugandan armed forces in the latest incident in what has been called an “ alarming crackdown ” on the country’s environmentalists.

    Stephen Kwikiriza, who works for Uganda’s Environment Governance Institute (EGI), a non-profit organisation, was abducted in Kampala on 4 June, according to his employer. He was beaten, questioned and then abandoned hundreds of miles from the capital on Sunday evening.

      From ‘hug a husky’ to ‘max out the oil’: the Tory environmental journey

      news.movim.eu / TheGuardian · Wednesday, 12 June - 05:00

    We look back through 14 years of Conservative manifestos at policies on net zero, energy, transport and more

    It’s been a long journey on environmental issues for the Tories – but somehow it feels as if it has been in the wrong direction. Eighteen years on from David Cameron’s “hug a husky” campaign of 2006, where the climate and nature crises were largely viewed with cross-party consensus, we look back through the (many) Tory manifestos since 2010 to see how the Conservatives’ environmental message has evolved.

      Salt, air and bricks: could this be the future of energy storage?

      news.movim.eu / TheGuardian · Monday, 1 April - 07:00

    Start-ups turn to heat over batteries as they aim to industrialise the practice

    Think of battery ingredients and lithium, cadmium and nickel come to mind. Now think again. What about salt, air, bricks, and hand-warmer gel? In our electricity-hungry future they’re set to provide heat to manufacturers who need it, and to help keep the lights on at times when energy is short.

    Energy storage has a dual purpose: it plugs gaps when the wind drops or the sun stops shining, and it allows users to buy cheap off-peak power and use it when they need it.

      Surge of new oil and gas activity threatens to wreck Paris climate goals

      news.movim.eu / TheGuardian · Thursday, 28 March - 06:00

    World’s fossil-fuel producers on track to nearly quadruple output from newly approved projects by decade’s end, report finds

    The world’s fossil-fuel producers are on track to nearly quadruple the amount of extracted oil and gas from newly approved projects by the end of this decade, with the US leading the way in a surge of activity that threatens to blow apart agreed climate goals, a new report has found.

    There can be no new oil and gas infrastructure if the planet is to avoid careering past 1.5C (2.7F) of global heating, above pre-industrial times, the International Energy Agency (IEA) has previously stated . Breaching this warming threshold, agreed to by governments in the Paris climate agreement, will see ever worsening effects such as heatwaves, floods, drought and more, scientists have warned.

      Sellafield’s head of information security to step down

      news.movim.eu / TheGuardian · Wednesday, 27 March - 16:21


    Richard Meal is second senior leader to depart following Guardian investigation into failings at UK nuclear waste site

    A former Royal Air Force officer who has led Sellafield’s information security for more than a decade is to leave the vast nuclear waste site in north-west England, it can be revealed.

    Richard Meal, who is chief information security officer at the Cumbrian site, is to leave later this year.

      Perovskite + silicon solar panels hit efficiencies of over 30%

    In most industrialized countries, solar panels account for only a quarter to a third of the overall cost of building a solar farm. All the other expenses—additional hardware, financing, installation, permitting, etc—make up the bulk of the cost. To make the most of all these other costs, it makes sense to pay a bit more to install efficient panels that convert more of the incoming light into electricity.

    Unfortunately, the cutting edge of silicon panels is already at about 25 percent efficiency, and there's no way to push the material past 29 percent. And there's an immense jump in price between those and the sorts of specialized, hyper-efficient photovoltaic hardware we use in space.

    Those pricey panels have three layers of photovoltaic materials, each tuned to a different wavelength of light. So to hit something in between on the cost/efficiency scale, it makes sense to develop a two-layer device. This week saw some progress in that regard, with two separate reports of two-layer perovskite/silicon solar cells with efficiencies of well above 30 percent. Right now, they don't last long enough to be useful, but they may point the way toward developing better materials.
