One controversial idea is known as bioenergy with carbon capture and storage, or BECCS: You’d grow crops and burn them for energy, then capture the emissions coming out of the facility and pump them underground as liquefied gas.

The problem stems from a combination of factors: aging infrastructure, a discombobulated electrical grid that makes it difficult to get renewable energy from where it is produced to where it is needed, and the overwhelmed regulators responsible for approving the projects.

Studies from the Natural Resources Defense Council (NRDC) have found that more than 100 billion kilowatt-hours are wasted every year because of vampire energy, “costing American consumers over $19 billion—about $165 per US household on average—and 50 large (500-megawatt) power plants’ worth of electricity.”.

“On that very first weekend when the price cap change came in, our inquiries increased by 300 percent,” says Richard Moule, a director at the Sheffield-based solar installers All Seasons Energy.

But a pair of recent studies suggest that those estimates are woefully out-of-date and undercounted, failing to include the energy-intensive processes required to produce modern, anode-ready graphite.Knowing the approximate carbon intensity of the power supply, he began mapping out the laborious steps for turning that graphite into anodes.

More than 200 longtime Wikipedia editors have requested that the Wikimedia Foundation stop accepting cryptocurrency donations.Earlier this month, the Mozilla Foundation announced it would stop accepting cryptocurrencies that use the energy-intensive proof-of-work consensus process.

That shift is clear in a darn near uplifting paper that publishes today in the journal Nature: Modeling by an international team of scientists shows that if nations uphold their recent climate pledges, including those made at COP26, humanity may keep warming under 2 degrees Celsius above pre-industrial levels, the goal outlined in the Paris Agreement.

“The IPCC tells us that we have the knowledge and the technology to get this done through a rapid shift from fossil fuels to renewable and alternative fuels,” said Inger Andersen, under-secretary-general of the UN and executive director of the UN Environment Program, speaking at the press conference.

Companies use energy and produce greenhouse gases directly, of course—by operating offices and data centers , making products, and converting carbon-absorbing wilderness into wasteland.

Of all the potential fixes for the climate crisis, none has captured hearts and minds quite like tree planting.If newly planted forests aren’t properly cared for and monitored, the trees can die and any carbon they stored will be released back into the atmosphere.

Next-generation ground-based observatories will be enormous, such as the Extremely Large Telescope, which will eclipse the size of the Colosseum in Rome when it is completed in 2024.Now some researchers are thinking about the carbon footprint of modern astronomy and realizing that they, like everyone else, might have to consider alternative ways of doing business in order to keep climate-warming emissions in check.

A spokesperson for the UK’s Department of Business, Energy and Industrial Strategy told WIRED the government is exploring a range of options, including extending the operation of coal-fired power stations that are due to close in September.

Do this again and again in a series of centrifuges known as a cascade, siphoning off the U-235 each time, and pretty soon you’ll have low-enriched uranium, fuel for a traditional nuclear reactor.

Or, in the winter, a heat pump can warm a building by operating as a sort of “reverse refrigerator,” extracting heat from even cold outdoor air and bringing it inside.

The test was years in the making, one of the final rituals in a drawn-out courtship between the Ukrainian and European power grids known as “synchronization.” But before it could join with Europe, Ukrenergo first had to prove it could keep the lights on without its connections to Belarus and Russia—in “island mode.” The plan was to reconnect with its neighbors after a few days.

But a hidden crisis is unfolding too: The carbon emitted by war machines is helping warm the planet at a critical moment in human history, when every day not spent decarbonizing adds to the compounding misery of climate change.

It turns out that massive wind turbines may interfere with marine radar systems, making it risky for both big ships passing through shipping channels near offshore wind farms and smaller vessels navigating around them.

While Baerbock said peace and freedom didn’t have a price tag, former Russian president Dmitry Medvedev was happier putting a number on the cost of shutting Nord Stream 2 down: “Welcome to the brave new world where Europeans are very soon going to pay €2,000 ($2,225) for 1,000 cubic meters of natural gas,” he tweeted.

Heating and cooling power consumption could range from a few hundred watts when the ambient temperature is close to optimal, 1-2 kW when the environment is very hot or cold, or even up to 5+ kW if the vehicle is starting off very cold and the battery needs to be warmed up by a resistive heater.”.

The state-owned company had been under pressure from the Swedish government to lower its carbon footprint by getting rid of the power plants and their coal pits, which sprawl across a vast stretch of eastern Germany close to the Polish border.

The Bitcoin and Ethereum platforms operate on a principle called “proof of work” (PoW), in which computers solve complex puzzles to verify a transaction, for which that computer (or “miner”) is then rewarded with some amount of the cryptocurrency.

If the goal is to charge up your electrical vehicle in, say, five minutes, that extra current meeting resistance means temperature-related problems inside the battery and out.“I question the wisdom of why we need to have 500-mile range in an electric car and also want fast charging in five minutes,” he says.

The wind powers a chemical plant that makes ammonia, which can not only be spread as fertilizer under the turbines, but also fuels an experimental tractor, stores energy for a non-windy day, and—soon—will heat the barns that dry their grains.

Last week, along with other battery and aviation experts, Viswanathan published in Nature what he considers a “wake-up call” to the industry to invest in basic science beyond moving around lithium ions.

This is digital, more of a timing strategy than a real battery, aimed at getting data-hungry companies like Google, Meta, Amazon, Apple, and Netflix to use clean power when it’s plentiful so utilities can avoid burning fossil fuels when it’s not.

Its neighbor Belgium currently sources nearly 40 percent of its electricity from nuclear power but has committed to closing down its seven remaining reactors by 2025.Critics of Europe’s nuclear shutdowns say losing reliable sources of low-carbon energy is the last thing we should be doing when we need to reduce emissions.

If there was any product revealed at CES last week that pushed battery life claims to a whole new level—and raised some eyebrows too—it was HyperX’s pair of 300-hour headphones.Srinivasan, like many other technologists these days, is optimistic that relatively new developments in silicon-anode technology will improve battery life.

Lia Siegelman had just been studying the swirling waters of the Southern Ocean, which surrounds Antarctica, when she happened to come across a poster image of cyclones around Jupiter’s north pole, taken by NASA’s Juno spacecraft .

Meta’s data center is “too big for a small town like Zeewolde,” says Schaap, who has become one of the project’s most vocal opponents.Like Schaap, other residents of Zeewolde are outraged that Meta has chosen their town for its first gigantic data center in the Netherlands.

As each block descends, the motors that lift the blocks start spinning in reverse, generating electricity that courses through the thick cables running down the side of the crane and onto the power grid.
