“The blackout is the culmination of decades of disinvestment, an economic crisis, and global factors affecting the country’s oil supply, and there doesn’t seem to be a long-term solution to the crisis.
The Cuban government regularly imposes hours-long blackouts in different parts of the country to conserve the fuel necessary to run the electrical plants. But the current outage is different. It was sparked by a breakdown at one of the country’s aging electrical stations and has affected every facet of life for ordinary people: They cannot cool or light their homes, food is spoiling in refrigerators, they cannot cook, and many can’t access water to drink or wash.
Though the situation has now reached a crisis point, it’s a tragedy that has developed over time and emphasizes Cuba’s fragile economy, development imperatives, and its tenuous place in world politics.”
“That solar power installations are going up as the technology improves and prices come down isn’t too surprising, but the sustained surge is still stunning.
“When you look at the absolute numbers that we’re on track for this year and that we installed last year, it is completely sort of mind-blowing,” said Euan Graham, lead author of the report and an electricity data analyst at Ember.
Several factors have aligned to push solar power installations so high in recent years, like better hardware, economies of scale, and new, ripe, energy-hungry markets. Right now, solar still just provides around 5.5 percent of the world’s electricity, so there’s enormous room to expand. But solar energy still poses some technical challenges to the power grid, and the world’s ravenous appetite for electrons means that countries are looking for energy wherever they can get it.
So if you’re concerned about climate change, it’s not enough that solar wins; greenhouse gasses must lose.”

“Energy storage technologies like batteries are also getting way better and cheaper. The price of batteries has tanked 97 percent since 1991. Because of better technology, falling costs, and more markets for saving power, the US is on track to double its grid energy storage capacity compared to last year. More than 10 gigawatts of solar and storage came online in 2023 across the country and that’s likely to double this year. “Energy storage is at an earlier stage [than solar] but we are likely to see rapid expansion in that segment, especially in regions where solar and wind penetration are high already such as California and Texas,” said Steve Piper, director of energy research at S&P Global Commodity Insights”
“Volatility in natural gas prices, including the huge spikes following Russia’s invasion of Ukraine, has certainly contributed to some price increases on the supply side. But the transmission and distribution costs have actually been going up at twice the rate of inflation nationwide, the report’s author, Brendan Pierpont, told me.
“That trend of increasing transmission and distribution costs is something that is noticeable all across the country, and so I think it’s an underlying factor in rate increases everywhere,” Pierpont said.
Utility companies have a lot of freedom in setting rates for transmission and distribution — and that directly contributes to how much profit they make. Utilities get to pick what gets upgraded when, and they also have an incentive to spend heavily, thanks to regulations that allow them to collect return on investment, usually around 10 percent, for those expenditures. This is actually built into the price most people pay for electricity.
Here’s how it works: Every year, utility companies ask regulators to approve a “revenue requirement,” which is basically a budget for what the utilities think it will cost to deliver enough electricity to their customers. Those estimates include spending on new equipment but not the cost of repairing old equipment. It also includes that return on investment, or profit, which regulators regularly approve. In Pierpont’s words, “That rate of return has a direct link to the costs that customers pay for electricity.”
What utilities don’t seem to be doing, however, is expanding the grid in a way that would benefit clean energy producers, the Energy Innovation report finds. Investments tend to cover local upgrades, like installing new metering equipment, rather than installing the high-voltage transmission lines that renewable energy sources need to connect to the grid. Meanwhile, consumers are facing more frequent outages that last longer, while utilities keep making more money for installing new, potentially unnecessary equipment.
“It’s like the utilities have a rewards credit card,” said Joel Rosenberg of Rewiring America, a nonprofit focused on electrification. “And they get to keep the rewards for how much they spend, and the [customers] have to pay off the bill, even if that bill takes 80 years to pay off.”
This plays right into the misconception that investment in renewables leads to higher rates.
Many of the states leading the way to clean energy are actually seeing lower energy prices than the rest of the country. Data from the US Energy Information Administration shows that 17 states, including California and Massachusetts, have increased their share of renewable energy sources by more than 20 percent since 2010. And with the exception of California, all of those states have seen the price of residential rate increases rise more slowly than inflation. The higher rates in California can be explained, in part, by rate increases to account for wildfire prevention. In Massachusetts, natural gas is the problem.
States where residents are seeing electricity bills that outpace inflation tend to be the ones with the highest reliance on natural gas, as highlighted in the Energy Innovation report. Some states in New England, including Massachusetts, have depended on natural gas for around 60 percent of electricity generation since 2020 and have seen prices increase by around 10 percent in the same period. Volatility in the price of natural gas also means that some of the highest price spikes are spread out over several years, so there could be more high prices in these states’ futures.”
“According to Dawson, nuclear power is “the most scalable, reliable, efficient, land-conserving, material-sparing, zero-emission source of energy ever created.” Wind and solar aren’t as reliable because they depend on intermittent weather. They also require much more land than nuclear plants, which use about 1 percent of what solar farms need and 0.3 percent of what wind farms require to yield the same amount of energy.
The economics of nuclear power are undoubtedly challenging, but its advocates say that’s primarily because of its thorny politics. The headache of building a new power plant is vividly exemplified by Georgia’s Plant Vogtle. The first U.S. reactor built from scratch since 1974, the project turned into a nightmare scenario: It took almost 17 years from when the first permit was filed for construction to begin, it cost more than $28 billion, and it bankrupted the developer in the process.
Nuclear regulation is “based on politics and fear-mongering and a lack of understanding,” explains Indian Point’s vice president, Frank Spagnuolo. If they aren’t shut down, he says, power plants such as Indian Point could safely continue to provide clean energy for decades. ”
“Whether LNG is better for the climate than other options is a topic of intense debate. If it replaces coal, then in general, yes. Since it’s made mostly of methane, it burns more cleanly than coal, producing roughly half of the greenhouse gas emissions. But it’s still a fossil fuel that contributes to warming, and every new gas terminal, transport tanker, and power plant implies these emissions will continue for decades more.
By one estimate, US LNG shipments to China reduced the intensity of greenhouse gas emissions — the amount of greenhouse gases released per unit of energy — by as much as 57 percent. Other analyses have also found that countries that import LNG produce power with lower emissions than with local coal. Another advantage is that gas produces fewer air polluting substances like particulates, so turning away from coal has immediate health benefits. And having more cheap gas on the global market could undermine the case for new coal power plants in some countries, if they can secure a reliable gas supplier.
But some environmental activists say this paints too optimistic a picture. For gas importers like the United Kingdom, LNG has a greenhouse gas footprint four times larger than gas extracted locally. Methane is itself a heat-trapping gas, about 30 times more potent than carbon dioxide, so small leaks from gas infrastructure — as little as 0.2 percent — can quickly overwhelm any environmental advantages. The added steps of chilling and shipping gas create even more opportunities for LNG to escape, and the industry has done a poor job of tracking its fugitive emissions. In addition, some LNG exports will simply fill in existing gas needs, as they do in parts of Europe, so the climate impact overall is at best a wash, though likely worse than more locally produced gas. At the same time, renewable energy is already the cheapest source of electricity in many parts of the world, and climate activists argue that gas no longer serves as a bridge to a low-carbon world.”
“Part of the reason that Texas sometimes struggles to make enough electricity is that it has a freewheeling power market with fewer interventions from regulators than those in other states. The priority is to sell electricity in real time at the lowest possible cost, with little backup margin, although that’s starting to change. Spurred by the 2021 blackout in Texas from Winter Storm Uri that cut off power to 4 million customers and killed at least 246 people, ERCOT implemented rules to encourage more reserve power on its grid.”
“If the economics can be made to work, geothermal would provide a renewable energy source that’s always on, and that employs plenty of ex-oil and gas workers, to boot. That has been its promise for decades. Maybe the 2020s will end up being the time that promise is finally fulfilled.”
“the White House has invested heavily in sustaining the country’s nuclear infrastructure, and President Joe Biden has also touted nuclear as an important component in the country’s quest for carbon neutrality. Many countries are following the same path based on similar climate calculations, and some experts support this position. “Nuclear is actually one of the cleanest and safest energy sources,” Kharecha says. For countries that want to mitigate climate change and reduce air pollution, he says that nuclear energy should be embraced — at least until better options come along.
But environmental advocacy groups and left-leaning American voters have traditionally opposed nuclear power. And, despite the president’s efforts, recent Gallup data suggest this is still the case: Less than half of Democrats back nuclear, compared to 62 percent of Republicans.”

“The Chernobyl meltdown captivated and horrified many Americans. But while the US shuddered, Germans suffered directly from the disaster’s fallout. It wasn’t just a question of tainted milk. Radioactive particles drifted across much of the German landscape. Sandboxes were nicknamed “death boxes.” Contamination turned up in meat, vegetables, fruits, and foodstuffs produced all over the country, and frightened parents didn’t know what to feed their children. Some experts estimated that hundreds of thousands of people on the continent would eventually develop Chernobyl-related cancers. That didn’t come to pass, but recent government analyses of German wild mushrooms found that 95 percent of samples still contained radioactive contamination from Chernobyl, and the residue of that disaster has likewise soaked deep into the nation’s views on nuclear power.”

“There are some unimpeachable justifications for opposing nuclear energy. There’s the risk of a catastrophic accident, first and foremost, and also the problem of storing or disposing of nuclear waste.
“From our point of view, it’s not right to say nuclear is a sustainable technology,” says Kopf, the Greens politician. “You need uranium, which is not extracted in an environmentally friendly way, and there is no real solution for nuclear waste.”
However, when making energy trade-offs, these risks must be balanced against the harms associated with the use of non-nuclear energy sources — such as air pollution and CO2 emissions produced by fossil fuels. According to estimates from Our World in Data, nuclear is cleaner and safer than any power source apart from solar. The number of deaths caused by either accidents or air pollution as a result of nuclear power is estimated to be just 0.03 deaths per terawatt-hour of energy produced. That is far, far below the 18 deaths and 25 deaths per terawatt-hour associated with oil and coal sources, respectively.”
