New climate law has bipartisan roots — we need leadership from both parties to realize its potential | The Hill

I have looked for how many degrees C this new climate (etc.) bill will reduce warming long term. I can't find an estimate. It should be pretty easy to contrive. I asked the MIT Climate Group to produce one, but they never responded.

I suspect I know why.

Why the getting financed by one side or the other?

Governments Are Rethinking Nuclear Power

https://www.msn.com/en-us/news/technology/governments-are-rethinking-nuclear-power/ar-AA11grPn?ocid=entnewsntp&cvid=630e6634352a4f90b1f511d28dd4cdd2

The crisis in Ukraine may be rushing in a new golden age for nuclear power. Recent announcements from Germany, California, and Japan—three places where early retirement of nuclear plants has been a heated policy debate—signal that the world’s energy crisis could be turning the tide on nuclear energy.

The process of decommissioning Germany’s nuclear plants has been a decades-long journey as part of its larger energy transition, known as Energiewende, but the retirements were accelerated after the Fukushima accident in 2011. Currently, only three of the 17 nuclear power plants that were operating a decade ago in Germany are still in use, providing about 6% of the country’s electricity; all three of these plants are scheduled to be retired by the end of this year.

“Germany has a really large and really strong anti-nuclear movement, ever since the 1980s,” said Jessica Lovering, the cofounder and executive director of Good Energy Collective, a pro-nuclear research group. “They felt that they were impacted from the fallout of Chernobyl, and that’s where that sort of movement gained a lot of momentum. Germany also has a very strong coal industry. The coal industry has long lobbied to close nuclear power plants, because that’s their competition.”

After Russia invaded Ukraine in March, Germany’s neighbor Belgium almost immediately worked out a deal with its nuclear provider, Engie, to extend the life of two of its reactors, which were set to be retired in the middle of this decade, for another 10 years. Germany, however, seemed set on keeping its initial retirement date, despite soaring energy prices—until this month, when Chancellor Olaf Scholz said he wanted to wait for the results of a comprehensive “stress test” later this year to determine whether or not the plants should be retired.

“It does make a lot of logical sense,” said Lovering. “They don’t have a lot of other options. They’re doing sort of everything they can to reduce gas consumption. And this is a really simple thing that can be done. Easy.”

That’s also the sentiment that seems to be prevailing thousands of miles away, in California. Earlier this month, Gov. Gavin Newsom announced that he would pressure to keep open Diablo Canyon, a 2,240-megawatt plant situated on California’s southern coast, to help with the state’s aggressive decarbonization goals; a draft bill, introduced late on Sunday, provides a pathway to extend the plant’s life an additional five years past its scheduled retirement date in 2025. “In the face of extreme heat, wildfires, and other extreme events that strain our current electrical system, the state is focused on maintaining energy reliability while accelerating efforts to combat climate change,” the governor’s office said in a statement earlier this month.

A slew of complex issues, including water permits and the steep costs of operation, led the California plant’s operator, Pacific Gas & Electric, to announce in 2016 that it planned to retire the facility at the end of its federal license—a welcome piece of news for anti-nuclear environmentalists in the state, who had long protested the plant thanks in part to its location along earthquake fault lines. But the plant, the last functioning nuclear plant in the state, provides almost 10% of California’s electricity, and the new bill allows up to $1.4 billion in loans from the state to keep the facility running.

“If you kept nuclear plants running, you could shut down coal plants,” said Matt Bowen, a research scholar at Columbia University’s Center on Global Energy Policy. “That would mean much lower CO2 emissions as well as much lower air pollution.”

Keeping aging plants open is one thing, but building new ones is a different conversation entirely—one that Japan, of all places, is wading into. Last week, Prime Minister Fumio Kishida said that Japan would consider restarting some of its nuclear plants, many of which have sat idle since the Fukushima disaster. Kishida also said that the country is exploring the option of building new next-generation reactors, with a goal of bringing them online in the 2030s.

“Japan is one of the best in the world in terms of building new nuclear power plants,” said Bowen.

Even though gearing up nuclear power could help wean countries and states off of fossil fuels, it doesn’t mean their reliance on Russia will go away entirely. Russia is one of the world’s most important stops in the supply chain for nuclear fuel, providing 46% of the world’s uranium enrichment capacity and 40% of its uranium conversion. If the crisis in Ukraine drags on for years, countries that are increasing or maintaining their nuclear capacity may need to find other sources for fuel production.

heck, no one thought the war would last a month, now it's over 6 months long and looking like Russia may have to back out and get nothing

Cincydawg · « **Reply #6363 on:** August 30, 2022, 04:10:00 PM »

I think Russia likely can hold what it has, mostly. It's a lot tougher to take than hold.

Germany and Denmark have agreed on a $9 billion deal to build an offshore wind power project in the Baltic Sea that authorities said would provide enough power for up to 4.5 million households by 2030.

Announced Monday, the deal involves Denmark boosting its planned wind power capacity on Bornholm Energy Island from 2 to 3 gigawatts, per State of Green, an energy and climate arm of the Danish government.

The deal also includes a 292-mile subsea cable that links Bornholm's wind parks to the German grid in a bid to reduce the region's reliance on Russian gas and oil.

Currently, Denmark and Germany have offshore wind power capabilities of 1.5 gigawatts and 1 gigawatts in the Baltic Sea, accounting for more than 90% of the region's wind energy, State of Green wrote in its statement.

The infrastructure to connect the wind parks will cost $3 billion, while $6 billion would be needed to bolster the wind parks, Bloomberg reported, citing the Danish government.

In State of Green's Monday statement, Dan Jørgensen, Denmark's minister for climate, energy, and utilities, called the project a "landmark in energy history" at a time when "international cooperation is more urgent than ever before."

Robert Habeck, Germany's minister for economic affairs and climate action, said the "flagship project" would help Europe achieve "energy security and climate neutrality."

On Friday, German Foreign Minister Annalena Baerbock emphasized her nation's desire to pursue the "enormous" potential of offshore wind energy in the Baltic Sea, which she said could generate up to 90 gigawatts of power.

"Wind energy from the Baltic Sea will help us fight the climate crisis. And it is an investment in our security: it will help make us less dependent on gas from Russia," she said.

The world's total wind power capacity — both onshore and offshore — is now up to around 837 gigawatts, according to the Global Wind Energy Council. China holds the largest share in the world's offshore wind market, having raised its offshore wind capacity to 27.7 gigawatts in 2021, per the GWEC.

The European Commission has set a target for increasing its nations' total wind power capacity to 300 gigawatts by 2050, up from the 16 total gigawatts they have installed as of May.

I dislike how they throw out these figures with no context, so many gigawatts. OK, what percentage of total power is that? Is that nameplate capacity or actual expected output?

Energy transition: The land use conundrum | Climate Etc. (judithcurry.com)

Abstract. The global energy system has a relatively small land footprint at present, comprising just 0.4% of ice-free land. This pales in comparison to agricultural land use– 30–38% of ice-free land–yet future low-carbon energy systems that shift to more extensive technologies could dramatically alter landscapes around the globe. The challenge is more acute given the projected doubling of global energy consumption by 2050 and widespread electrification of transportation and industry. Yet unlike greenhouse gas emissions, land use intensity of energy has been rarely studied in a rigorous way. Here we calculate land-use intensity of energy (LUIE) for real-world sites across all major sources of electricity, integrating data from published literature, databases, and original data collection. We find a range of LUIE that span four orders of magnitude, from nuclear with 7.1 ha/TWh/y to dedicated biomass at 58,000 ha/TWh/y. By applying these LUIE results to the future electricity portfolios of ten energy scenarios, we conclude that land use could become a significant constraint on deep decarbonization of the power system, yet low-carbon, land-efficient options are available.
