There are about 440 nuclear power reactors operating in more than 30 countries that supply about 10% of the world’s electricity, according to the World Nuclear Association. Currently, 55 new reactors are being constructed in 19 countries, and 19 of those are in China. The U.S. only has two underway…. Currently, three new nuclear reactors are being built in Russia. But Russia is also the world’s top nuclear technology exporter….

As Russia and China have risen to prominence, the United States has lost “the muscle memory” to build conventional nuclear reactors, Luongo said. Nuclear power got a poor reputation in the United States after the nuclear accident at Three Mile Island in 1979 in Pennsylvania, and more globally after the accidents at Chornobyl in the Ukrainian Soviet Union in 1986 and Fukushima in Japan in 2011. But the tide is starting to turn. The Biden administration’s solution was included in the Bipartisan Infrastructure Law, which was signed into law November, and was effectively a big subsidy. The law includes a $6 billion program intended to preserve the existing U.S. fleet of nuclear power reactors…. At the same time, the Russia-Ukraine war gives the United States leverage to pry open more of a footprint in the global market. While the war is tragic, “it’s going to result in more opportunity for U.S. nuclear firms as Russia really disqualifies itself,” said John Kotek of the Nuclear Energy Institute [a U.S. nuclear industry trade association]. Russia’s dangerous attack at Zaporizhzhia nuclear power plant in Ukraine and China’s decision to not vote in favor of the IAEA’s resolution to prevent the kind of attack “will blowback on both countries’ nuclear export reputation,” Luongo told CNBC….

Nuclear plants are expensive to build and have, in many places, become more expensive than other baseload energy alternatives like natural gas. However, the U.S. is pushing hard into what could become the next generation of nuclear. “The United States has made a decision that they don’t want to allow Russia and China to dominate that next phase of the nuclear market. And so the U.S. is pouring billions of dollars — shockingly — billions of dollars into the development of what are called small modular reactors,” Luongo said. Specifically, the government is using the Idaho National Lab as a testing ground for these reactors.
Without specifically mentioning nuclear energy, former Gawker editor Alex Pareene recently argued a program of “mass electrification and renewable energy” could diminish the power of “oligarchic petrostates.”

“With a venture creating the same little power plants for apartment buildings, Texas has become a national leader in residential solar power installations.”

From 2019 to 2020, small-scale solar capacity in Texas grew by 63 percent, to 1,093 megawatts from 670 megawatts, according to the Energy Information Administration. In the first three quarters of 2021, another 250 megawatts of residential solar were installed in the state, according to the Solar Energy Industries Association. In last year’s third quarter alone, Texas ranked second behind California in the amount of power from new installations during the period, the industry’s Washington, D.C. trade group said.

Surging demand for residential solar power in Texas after the February 2021 freeze put pressure on installers to keep up, said Abigail Hopper, president and CEO of the association. The race to buy new rooftop panels has slowed some, she said, but Texas remains among the top three states for new installations. And the shrinking price of solar cells will help support its growing popularity, Hopper said.

“I think as more and more Americans really struggle with the impact of severe weather — everything from fires, the cold, hurricanes, droughts — and see the impacts on power and power outages, you’re going to continue to see folks looking for resiliency,” Hopper said.

That alone amounts to a major scaling up of offshore wind capacity in the US. The nation so far only has two operational wind farms along its coasts — off the shores of Rhode Island and Virginia — with a combined capacity of just 42 MW. That’s set to change dramatically over the next few years. Orsted and Eversource, the energy companies developing South Fork, have an even bigger project in the works nearby: Sunrise Wind, a 924-MW wind farm that’s expected to break ground next year. Altogether, all the offshore projects under development in New York state’s current portfolio total over 4,300 MW of clean energy. By 2035, the state hopes to harness more than twice as much renewable energy from offshore wind.

Habeck intends to remove restraints on onshore wind development caused by concerns about radar installations for civilian and military aviation. He estimates the government plan could free up 4 to 5 GW of new wind projects currently blocked by aviation radar, and an additional 4 GW currently blocked by the military. Support for renewable energies will be paid from the state budget, reducing the burden on low income households and small businesses. The package is also said to define the energy transition as a ‘matter of public interest’ in order to prioritize wind energy projects over other forms of land use — an important precondition to streamlining the permit process and finding new sites for wind energy projects.

There are now at least 35 companies trying to prove that fusion can be a practical power source, most of them established in the past decade, according to the three-year-old Fusion Industry Association. The promise of fusion was buoyed with significant developments this year. In May, scientists in China used their own specially designed tokamak to sustain a fusion reaction of 120 million degrees Celsius for 101 seconds, the longest on record. In September, Whyte’s team at MIT and his colleagues at Commonwealth Fusion Systems demonstrated that, while using relatively low-cost materials that don’t require a large amount of space, they could create the most powerful magnetic field of its kind on Earth, a critical component of the prototype reactor they’re building in Devens.

“We have come a long way,” said Bob Mumgaard, CEO of Commonwealth Fusion Systems, who compared their advance to similar breakthroughs that made flight possible. “We’re a pretty conservative science bunch, but we’re pretty confident.” With some $2 billion raised in recent years — more than any of the other fusion startups — his company is racing to prove that their prototype, called SPARC, will produce more energy than it consumes in 2025. If they succeed, the company plans to start building their first power plant several years afterward. Ultimately, he said, their goal is to help build 10,000 200-megawatt fusion power plants around the world, enough to replace nearly all fossil fuels. “This is a solution that can scale to the size of the problem that decarbonization requires,” he said.

Phil Warburg, a senior fellow at Boston University’s Institute for Sustainable Energy, disagrees. “Fusion has been an elusive fantasy for a half-century or more,” he tells the Boston Globe. “Along with the technical hurdles, the environmental downsides have not been seriously examined, and the economics are anything but proven… The current wave of excitement about fusion comes at a time when we’ve barely begun to tap the transformative potential of solar, wind, storage, and energy efficiency — all known to be technically viable, economically competitive, and scalable today. The environmental advocacy community needs to focus on vastly expanding those clean-energy applications, leaving fusion to the scientists until they’ve got something much more credible to show for their efforts.”

But Elizabeth Turnbull Henry, president of the Environmental League of Massachusetts rejected the argument that fusion research detracts from investments in renewables as a “false choice…. We’re at a very different moment now, and it’s good to have a lot of different horses in the race.”

The also article notes that officials at America’s Nuclear Regulatory Commission told them federal officials are already holding meetings to discuss how they’d regulate fusion reactors.

The Spirit of Innovation didn’t stop there, though. Rolls-Royce affirms that it smashed another record when it reached 9,842.5 feet (3,000 meters) in 202 seconds, beating the current record by 60 seconds. In the company’s view, it also took the title of the world’s fastest all-electric vehicle when it reached a maximum speed of 387.4 mph (623 km/h) during its flight tests. The company’s aircraft is powered by a 400kW electric powertrain and “the most power-dense propulsion battery pack ever assembled in aerospace.” “Following the world’s focus on the need for action at COP26, this is another milestone that will help make ‘jet zero’ a reality and supports our ambitions to deliver the technology breakthroughs society needs to decarbonize transport across air, land and sea,” CEO Warren East said in the news release.

Toyota’s hydrogen-powered car underscores the automaker’s belief that a wide variety of vehicle types — including hybrids and hydrogen-powered cars, in addition to electric vehicles — will play a role in decarbonizing its fleet over the coming decades. That puts the company in contrast to others, such as General Motors Co., Jaguar Land Rover and Volvo Car AB, which say they’ll sell only EVs two decades from now. “The enemy is carbon, not internal combustion engines,” Toyoda said at a briefing Saturday. “We need diverse solutions, that’s the path toward challenging carbon neutrality.”

Toyota says that that different emissions-reducing car technologies are needed for different regions of the world. EVs are a good option for places like Europe, where batteries can be charged with electricity derived largely from renewable sources, the automaker says. Other options, such as hydrogen or hybrids, may be a better fit in other regions.

The technology is separate from the company’s other big bet on hydrogen — hydrogen fuel cells such as those that power the Mirai passenger car. While fuel cells use the chemical reaction between hydrogen and oxygen to generate electricity, which in turn runs a motor, the hydrogen engine burns the element just like gasoline. Traditional engines only need to be tweaked in minor ways, such as changing out the fuel supply and injection systems, to make them capable of running on hydrogen, Toyota Chief Engineer Naoyuki Sakamoto said in a briefing last month. That also makes the technology a way to save some of the hundreds of thousands of jobs making parts related to combustion engines that are predicted to disappear in Japan if the automotive sector makes a full shift to EVs, according to Toyoda.
