“The IEA predicts that within the next three decades, two-thirds of the world’s homes could have air conditioners. About half of these units will be installed in just three countries: India, China, and Indonesia. The extent to which these new air conditioners will exacerbate climate change hinges on replacing the cooling tech we currently use with something better. Right now, ideas range from retrofitting our windows to more far-out concepts, like rooftop panels that reflect sunlight and emit heat into space. To succeed, however, the world will need to boost the efficiency of the appliances we already have — as quickly as possible — and invest in new tech that could avoid some of AC’s primary problems.
The AC’s noxious environmental impact stems from its core technology: vapor compression. This tech involves several components, but it generally works by converting a refrigerant that’s stored inside an AC from a liquid to a gas, which allows it to absorb heat, removing it from a room. Vapor compression uses an immense amount of electricity on the hottest days, and there are growing concerns that the technology might eventually overwhelm the grid’s capacity to provide power. And hydrofluorocarbons, the chemical refrigerants that many ACs use to soak up heat, are greenhouse gases that trap lots of heat in our atmosphere when leaked into the air. The challenge is that, for now, vapor compression ACs are still a critical tool during deadly heat waves, especially for high-risk populations, young children, older adults, and people with certain health conditions.
Technology to build cleaner, more efficient air conditioners does exist. Two major AC manufacturers, Daikin and Gree Electric Appliances, shared the top award at last year’s Global Cooling Prize, an international competition focused on designing climate-friendly AC tech. Both companies created ACs with higher internal performance that used less environmentally damaging refrigerants; the new units could reduce their impact on the climate by five times. These models aren’t yet on the market — Gree plans to start selling its prototype in 2025, and Daikin told Recode that it hopes to use the new technology in future products — but the IEA estimates that using more efficient ACs could cut cooling’s environmental impact by half.
Another strategy is to double down on heat pumps, which are air conditioners that also work in reverse, using vapor compression to absorb and move heat into a home, instead of releasing it outside. Heat pumps usually cost several thousand dollars”
…
“heat pumps are not the easiest appliance to install, especially for renters, who don’t necessarily have the money or ability to invest in bulky HVAC systems.”
…
“While many of these technological breakthroughs are promising, the movement to revolutionize air conditioning still faces some major challenges. Right now, AC manufacturers primarily focus on meeting minimum performance standards, rather than competing for higher levels of efficiency. Consumers also tend to buy air conditioners based on their sticker price, not an AC’s overall impact on their energy bills. And even though there are a growing number of AC-focused startups, the industry is still dominated by a small handful of large companies, all of which primarily focus on far-from-ideal vapor compression tech.”
…
“if better, more affordable AC doesn’t come to market fast enough — especially for the vast number of people in developing countries who will buy these appliances in the coming decades — significantly worse air conditioners will take their place, warming the planet even faster.”
“The policies overall aim to push American consumers and industry away from reliance on fossil fuels. The biggest share of the funding goes to tax credits and rebates for a host of renewable technologies — solar panels, wind turbines, heat pumps, energy efficiency, and electric vehicles. It includes incentives for companies to manufacture more of that technology in the United States. The law will also put funding into energy efficiency at industrial sites that can help lower the sector’s hefty carbon footprint, while dedicating some funds to forest and coastal restoration.
The IRA also breaks new ground on other problematic areas of the climate crisis. It sets the first methane fee that penalizes fossil fuel companies for excess emissions of the especially powerful climate pollutant. Another substantial part of the funding helps disadvantaged communities with monitoring and cleaning up pollution, and builds their resilience to climate impacts.
Beyond cutting climate pollution, the clean energy investments could also make a dent in inflation. According to Robbie Orvis, senior director at Energy Innovation, rising energy prices have driven roughly a third of the 9 percent rise in the overall Consumer Price Index this past year. By helping Americans become less reliant on fossil fuels, the spending helps ease the global oil crunch and cut consumer bills.”
…
“The agreement also includes a 15 percent minimum tax on corporations with profits over $1 billion. Senate Democrats note that while the current corporate tax rate is 21 percent, dozens of major companies, including AT&T, Amazon, and ExxonMobil, pay much less than that. Originally, the provision was expected to raise $313 billion, though new carveouts were added to win Sen. Kyrsten Sinema’s (D-AZ) vote, which give manufacturers and private equity firms more leeway when it comes to the new minimum tax rate. Those changes are likely to reduce the revenue this measure will bring in.
There is also a 1 percent excise tax on corporations’ stock buybacks, which are currently not subject to any taxes at all. That excise tax is estimated to raise roughly $73 billion in revenue.”
“One big question is whether a bill called the Inflation Reduction Act will lower the decades-high inflation numbers that consumers are feeling at the grocery store and the gas pump.
As economists told Vox’s Li Zhou, the average American likely won’t feel the impact immediately or particularly significantly — its effect will be in a longer-term and macroeconomic sense.
“For the most part, this isn’t a bill about 2022,” Marc Goldwein, the senior policy director at the Committee for a Responsible Federal Budget, told Vox. “This is about 2023, 2024, 2025. It’s about helping the Federal Reserve to fight against persistent inflation. It’s not gonna be bringing down the inflation rate in the month of September.””
…
“the bill will allow Medicare to negotiate for cheaper prescription drug prices for certain very expensive medications and cap out-of-pocket prescription costs for Medicare beneficiaries at $2,000 per year. That unprecedented measure will lower the cost for consumers. A further measure requires pharmaceutical companies to pay a rebate to Medicare if they raise drug prices faster than inflation increases, NPR reported — presumably disincentivizing those companies from repeated price increases.”
…
“In addition to cementing Medicare’s new negotiating power, the bill also holds insurance subsidies for the Affordable Care Act through 2025, making health insurance more affordable for the millions of people who are insured through the health care marketplace. The initial subsidies were supposed to end this year, which would have meant increased premiums for the millions of people who qualified for free health insurance when Congress eliminated the income cap to qualify for federal assistance paying premiums.
The IRA also includes the largest-ever investments in climate change mitigation efforts, clean energy production, and climate justice programs, all designed to mitigate harmful effects of climate change in underserved areas.”
…
“While much of the financial incentives for pursuing clean energy and climate change mitigation are geared toward companies, there are rebates and tax credits available for people buying clean energy sources like heat pumps and rooftop solar panels. Those measures are aimed at making clean energy more available to more people, although solar panels, for example, cost about $11,000 in 2021 for a household setup.
The legislation also offers a $4,000 tax credit for low- and middle-income drivers to buy a used electric vehicle, and up to $7,500 for a new electric vehicle. Additionally, a study by the Rhodium Group estimates that the bill’s provisions will save households an average of $1,025 per year by 2030.”
…
“Even though all of these measures are in place, there is no question that the environmental actions and funding aren’t enough. The bill provides far less than what’s actually needed: a total system overhaul. It will be years before these programs will be implemented and pay off in the form of lower greenhouse gas emissions, better health outcomes for low-income communities, and improved clean energy infrastructure. However, it’s hard to deny that the IRA provides a glimmer of hope that it’s possible to start addressing some of the most pressing problems — including overwhelming health care costs and climate change.”
“Farms cover roughly 40 percent of the country, and they’ve replaced countless ecosystems with vast fields of soybeans, corn, and cattle. Agriculture also accounts for about 11 percent of US greenhouse gas emissions.”
…
“The biggest chunk of money — roughly $8.5 billion — goes toward a program run by the US Department of Agriculture called the Environmental Quality Incentives Program. It pays for projects that restore the ecosystem or reduce emissions on farmland.
Farmers often use the money to buy and plant cover crops. These are plants, such as clover, radishes, or rye, that are rooted in fields that might otherwise be fallow to improve the health of the soil and prevent erosion. The idea is that the ground is always “covered” with something.
Cover crops also have a range of other superpowers, said Rob Myers, director of the Center for Regenerative Agriculture at the University of Missouri. During a drought, for example, they can lock moisture in the soil; during a flood, meanwhile, they help water more easily penetrate the ground.”
“The IRA uses tax credits to incentivize consumers to buy electric cars, electric HVAC systems, and other forms of cleaner technology, leading to less emissions from cars and electricity generation, and includes incentives for companies to manufacture that technology in the United States. It also includes money for a host of other climate priorities, like investing in forest and coastal restoration and in resilient agriculture.
These investments, spread out over the next decade, are likely to cut pollution by around 40 percent below 2005 levels by 2030, according to three separate analyses by economic modelers at Rhodium Group, Energy Innovation, and Princeton University. The legislation helps move the US a little closer to its stated goal of cutting pollution in half within the decade.
The main climate change components of the Inflation Reduction Act look surprisingly similar to the version the House passed last fall, a measure widely celebrated by climate activists — although it’s smaller than the $2 trillion the Biden administration once envisioned. To win Sen. Joe Manchin’s (D-WV) support, Democrats added provisions that clear permitting roadblocks for some fossil fuel projects and force the Department of Interior to hold more offshore oil lease sales.”
…
“There is plenty the act does that is not about climate change. There’s funding for the Affordable Care Act, the IRS, and prescription drug reform. It also sets a corporate minimum tax — one of the ways the law helps tackle inflation. But this is arguably a climate law, as climate initiatives make up the biggest portion of the act’s investments.
The deal retains most of the key programs of the House’s Build Back Better Act, including consumer tax credits for solar panels and electric vehicles, and funding for domestic clean energy manufacturing.”
“One of the most damaging legacies of the intersection between racism and fossil fuels is how highways were built to cut through Latino and Black communities. The Federal-Aid Highway Act of 1956 alone displaced more than 1 million people, according to the Department of Transportation. People who remained near these roads, overwhelmingly communities of color, were exposed to more fine particulate matter from the tailpipes of cars and trucks.
That legacy lingers today. A mountain of research has shown how Black people nationwide are exposed to more damaging pollution from construction, power plants, roads, and industry than white people.
The Inflation Reduction Act includes a federal infusion of cash for community projects aimed at addressing some of the harmful effects of these projects. There is $3 billion marked for Neighborhood Access and Equity Grants, in addition to $1 billion already approved under the bipartisan infrastructure law last fall.
The money can be used for many things, including improving walkability, capping wells, installing noise barriers, and reducing the urban heat island effect. But one way communities could use the funding is to just remove a road, highway, or other types of damaging infrastructure. They can also reconnect communities divided by highways in other ways: “multi-use trails, regional greenways, or active transportation networks and spines.””
…
“Slashing climate emissions requires doing two things at once: electrifying things like cars and stoves that typically run on fossil fuels, while also cleaning up fossil fuels in the power sector so that pollution doesn’t just come from another source. That’s the reason the US will have to shut down its last 172 coal plants within the decade to finally make good on its climate promises.
One surprising policy to help with this transition made it into the final bill, even though it needed Sen. Joe Manchin’s (D-WV) sign-off: $10 billion in direct payments to rural electric co-ops that pay for the cost of a clean energy transition. The USDA will administer direct payments for these co-ops to retire coal-fired power plants.
Many of the last coal plants standing are serving rural communities. E&E News noted that “about 32 percent of the power that supplies co-ops nationwide came from coal in 2019.” Investor-owned utilities, by contrast, generated 19 percent of their electricity from coal in 2020.
These rural co-ops, which are collectively owned and governed by the communities they serve, have moved away from coal slowly more for economic reasons than political ones. These coal plants tend to be newer, and the communities they serve may be more risk-averse to transitioning to renewables because they have to pay directly for the cost of the transition.
But before rural communities can even think about transitioning to solar and wind, first they have to shut down the coal plants. And that can be expensive because it includes paying off any debts. (A separate $5 billion Department of Energy program in the bill offers loans that lower debts and costs for privately owned utilities to transition to renewables.)”
…
“The more controversial part of the bill is its funding of carbon capture for oil, coal, and industrial sites. Typically, these technologies have been used to just pump CO2 back in the ground for more drilling, rather than to do anything about the climate crisis. Still, prevailing climate science shows that some of this technology is probably needed to address the harder-to-decarbonize parts of the economy. So the federal funding for scaling new technologies could manage to go a long way over the long term.”
…
“the act includes $20 billion for “climate-smart” agriculture, which could help farmers store more carbon in their soil and plants.
Part of that money, for example, will go toward an initiative called the Conservation Stewardship Program, which essentially pays farmers to make their land more environmentally friendly, such as by planting cover crops. Cover crops, planted when the ground would otherwise be fallow, are one way to increase a farm’s potential to store carbon (and can also help avoid emissions).
Another $5 billion in funding goes toward preventing wildfires and protecting old-growth forests, which are rich in carbon. This is critical because the US is expected to lose more of its natural carbon sinks over time under business-as-usual scenarios.”
“heat is the deadliest weather phenomenon in a typical year in the United States, killing an average of 148 people annually in the 30 years from 1992 to 2021, and climate change is only going to make heat waves more common. We already categorize tornadoes, and we name wildfires. Hurricanes get both. Would extending those ideas to heat waves help?”
“”In 2000, Germany launched a deliberately targeted program to decarbonize its primary energy supply, a plan more ambitious than anything seen anywhere else,” Vaclav Smil wrote in 2020 for the Institute of Electrical and Electronics Engineers’ IEEE Spectrum. “The policy, called the Energiewende, is rooted in Germany’s naturalistic and romantic tradition, reflected in the rise of the Green Party and, more recently, in public opposition to nuclear electricity generation.”
The problem, as Smil noted, is that government-favored and subsidized solar and wind are intermittent. Wind doesn’t generate electricity when the air is still, and solar is of little use at night and on cloudy days. That means old-school generating capacity has to be maintained in parallel to the new systems.
“It costs Germany a great deal to maintain such an excess of installed power,” Smil added. “The average cost of electricity for German households has doubled since 2000. By 2019, households had to pay 34 U.S. cents per kilowatt-hour, compared to 22 cents per kilowatt-hour in France and 13 cents in the United States.”
The German news magazine Der Spiegel came to a similar conclusion in 2019.
“The state has redistributed gigantic sums of money, with the [Renewable Energy Sources Act] directing more than 25 billion euros each year to the operators of renewable energy facilities,” the authors observed. “But without the subsidies, operating wind turbines and solar parks will hardly be worth it anymore. As is so often the case with such subsidies: They trigger an artificial boom that burns fast and leaves nothing but scorched earth in their wake.”
Making the matter worse is the extent to which Europe has sourced its fossil fuels from Russia. That’s a dependency partly based on easy accessibility by land to Russia’s resources. It’s also an artifact of economic diplomacy from the Cold War era intended to build trade ties to reduce the risk of conflict. But what was supposed to give the West leverage over the old Soviet Union has instead handed modern Russia enormous clout.
Comparatively clean nuclear energy might have made the difference, but the 2011 Fukushima disaster spooked Germans more, perhaps, than people anywhere else, and the country resolved to abandon nuclear power, leaving it dependent on unreliable solar and wind and, especially, imported fossil fuels. Only now, with Russia throttling the supply of natural gas to 20 percent of capacity, is the governing coalition considering extending the life of the last two nuclear power plants past the end of the year.”
“Germany is one of the few places in the world where meat consumption is decreasing — and fast.
In 2011, Germans ate 138 pounds of meat each year. Today, it’s 121 pounds — a 12.3 percent decline. And much of that decline took place in the last few years, a time period when grocery sales of plant-based food nearly doubled.
The trend runs counter to virtually everywhere else on the planet, where meat consumption is quickly rising — from citizens of low-income countries adding more meat to their diet as incomes increase, to rich countries where meat consumption has more or less plateaued at a high level or continues to slowly increase. (Sweden, like Germany, is a notable exception.)”
…
“Meat and dairy production account for around 15 percent of global greenhouse gas emissions, and most countries’ per capita meat consumption far exceeds the 57 pounds per year recommended by the EAT-Lancet Commission, a panel of climate and nutrition experts.”
…
“One poll found that, from 2016 to 2020, the number of vegans in Germany doubled, hitting 2.6 million people or 3.2 percent of the population. A big jump, to be sure, but not enough to explain the sharp decline in the country’s meat consumption.
Rather, says Jens Tuider of ProVeg International, a Berlin-based organization that advocates for reducing meat consumption, “it’s the flexitarians that drive this development.”
Experts say the rise in flexitarians — those who reduce but don’t eliminate their meat consumption — could be due to a number of scandals in recent decades that have put the German meat sector under closer scrutiny. Exposés of forced labor in slaughter plants, reports of rotten meat sold across the country, bird and swine flu outbreaks, and animal cruelty investigations may have affected attitudes toward meat.
But those same problems are playing out elsewhere with far less effect on diet, including in the US, where Americans eat 225 pounds of red meat and poultry (fish excluded) per capita per year, almost twice the amount as Germans.
What seems to set Germany apart is its young people, who are deeply worried about climate change and see reforming the food system as one way to pump the brakes on their country’s greenhouse gas emissions. “Especially among the young people, you can see a cultural change, because they are much more aware of … what they eat, how they consume,” says Inka Dewitz of Heinrich Böll Stiftung, a foundation in Germany that is affiliated with the German Green Party.”
