Wind and Solar Saved the US $250 Billion Over 4 Years, Report Finds (arstechnica.com) 170

An anonymous reader quotes a report from Ars Technica: When used to generate power or move vehicles, fossil fuels kill people. Particulates and ozone resulting from fossil fuel burning cause direct health impacts, while climate change will act indirectly. Regardless of the immediacy, premature deaths and illness prior to death are felt through lost productivity and the cost of treatments. Typically, you see the financial impacts quantified when the EPA issues new regulations, as the health benefits of limiting pollution typically dwarf the costs of meeting new standards. But some researchers from Lawrence Berkeley National Lab have now done similar calculations -- but focusing on the impact of renewable energy. Wind and solar, by displacing fossil fuel use, are acting as a form of pollution control and so should produce similar economic benefits. Do they ever. The researchers find that, in the U.S., wind and solar have health and climate benefits of over $100 for every Megawatt-hour produced, for a total of a quarter-trillion dollars in just the last four years. This dwarfs the cost of the electricity they generate and the total of the subsidies they received. [...]

As a result, the environmental and health benefits of wind in 2022 are estimated as being $143 for each Mw-hr, with solar providing $100/Mw-hr in benefits. Given the amount of power generated by wind and solar that year, that works out to a total of $62 billion and $12 billion, respectively. For the entire 2019-2022 period, they total up to $250 billion. Due to the uncertainties in various estimates, the researchers estimate that the real value for wind is somewhere between $91 and $183 per Mw-hr, with solar having a proportionate uncertainty. For comparison, they note that the unsubsidized costs of the electricity produced by wind and solar range from $20 to $60 per Mw-hr, depending on where the facility is sited. So, in some ways, the companies that own these plants are only receiving a very small fraction of the benefits of their operation. Wind and solar do receive subsidies, but even the most generous ones provided by the Inflation Reduction Act max out below $35/Mw-hr -- again, far less than the health and environmental benefits. The researchers note that most of these benefits (about 75 percent) come from the reduction in carbon dioxide emissions. Still, the nitrogen and sulfur emissions reductions were also substantial: They displaced the equivalent of roughly 20 percent of the power sector's total emissions of these chemicals. That translates into avoiding about 1,400 premature deaths in 2022 alone.
The researchers acknowledge a number of limitations to their work. "One big one is that they don't include distributed solar at all, meaning their totals for that form of production are a significant underestimate," reports Ars, noting that the Energy Information Agency estimates that, in the U.S., distributed solar accounts for over 30 percent of total solar production. "It also, as mentioned, doesn't account for the use of storage such as batteries, which are increasingly used to offset the tail-off in solar production in the evenings."

"In addition, their work doesn't account for the intermittency of renewable power sources, which can sometimes result in the use of less efficient fossil fuel plants and so offset some of these benefits. The drop of wind and solar prices are also influencing decisions on what types of fossil fuel plants are getting built, disfavoring coal and increasing investments in natural gas plants that can respond quickly to changes in renewable output. Over the long term, this will result in additional benefits that can't be captured by this sort of short-term analysis."

The study has been published in the journal Cell Reports Sustainability.

    Removing 250 billion in transactions? Economists won't be happy about that.

    The first economist sees a pile of dog shit and says to the other, "I'll pay you $50 to eat that dog shit." So he does and gets paid $50. Later on, the second economist sees a pile of dog shit and says to the first, "I'll pay you $50 to eat that pile of dog shit." So he does and gets paid $50.

    The first economist says, "I can't help but feel we just ate dog shit for nothing." "Nonsense," says the second economist, "We just contributed $100 to GDP."

      Real economists would understand things become cheaper over time as we improve our efficiencies. And this usually allows consuming more of that thing, whatever it is.

      (Gas prices for example are allowed to float just for this reason. If there is a glut, people will take more roadtrips thanks to cheaper gas. If there is a shortage prices rise sharply, people only to essential trip, and then the price tapers to a more reasonable, but still high point by itself).

    But, I for am glad that we are investing in solar. We as a nation waste tremendous amounts on utterly pointless endeavors. But solar is one of the few things we do that is actually worthwhile. Once the equipment is installed, cost of energy is close to $0. And best of all, we are putting less toxic shit in the air. And reduced pollution due to increased EV use is cherry on top.

    I don't fully understand why people are against this sort of thing that benefits us all.

    Not having to ramp up ($$$$) the military to go "liberate" oil producing nations when they threaten our oil supply is a nice perk.
     
    Also helps that the US now produces as much oil as either Russia or Saudi Arabia these days.

      If Germany had kept their nuclear power plants operational then maybe that would have left Putin without as much leverage to invade Ukraine. Putin was betting on using natural gas supplies to Europe as a means to keep most of Europe from getting involved in protecting Ukraine from invasion.

      • When Putin threatened with the gas supply, Europeans simply stocked up on firewood, just like in the good old bad old days. I have about a three year supply of wood, and same goes for most people in the countryside. There are also many small gas fields in Europe that were brought online again - I literally live on top of a small field. It was mainly the doofus Germans that were left scrambling.
    • If we all stopped using oil today, there would still be plenty of things for the world's nations to fight about.

      Russia's invasion of Ukraine is certainly not about oil. Same for Gaza. Same for Haiti.

    The article and the paper it summarizes are a moderately confusing mix of "climate and health benefits".

    like: "These emission reductions provided $249 billion of climate and health benefits" and as the summary here says: "The researchers note that most of these benefits (about 75 percent) come from the reduction in carbon dioxide emissions".

    Now how exactly does CO2 cost money?
    "The social cost of carbon (SCC) provides an estimate of the global monetary damage per incremental metric ton of carbon dioxide (CO2) released. Estimates of the SCC have increased over time with methodological improvements. Rennert et al.8
    find a central-value SCC of $185/tCO2, 3.6 times larger than prior estimates used by the United States government."

    Rennert et al is this paper in https://www.nature.com/article... [nature.com] which is complex to say the least. models on top of models on top of models.
    It bases its nummbers on thing like: "The roughly 300-year time horizon required to account for the vast majority of discounted future damages;"
    and a $10M / person VSL (value of statistical life) for people who are going to die in future heatwaves and such.

    That $10M number is quite high (https://www.npr.org/2020/04/23/843310123/how-government-agencies-determine-the-dollar-value-of-human-life) and is not age adjusted by them afaict. and heatwaves kill primarily frail elderly people ... so counting each of those incremental deaths as $10M seems unreasonable.

    In any case, whele these stochastic processes are the right way to go, imo, the error bars in these papers are huge. eg. that $185 / ton of CO2 comes with 95-th percentile confidence interval of $12-$682 ... that's a lot.

      A 10 million per person total life value is very doable. And before we continue, I assume, the average diminished lifespan due to the pollution of fossil fuel is calculated as a fraction in total lifespan (75 odd years?) lost in respect to that 10 million.

      For a simple calculation to someones total economic contribution over his/her lifespan:
      An adult that earns $30.000 per year over its working life of 40 years (25-65), builds an economic output in that 40 years of over 10 million $US ($10,548,097. 65 to be

  • All solar, wind (green) energy systems have a payback time. Without government subsidies which are not "Free Money" the payback time is on the order of 10 years. Most of this stuff did not exist 10 years ago so it's not saving us anything yet. If you include the cost of all the failed solar and wind and wave power systems that did not survive their expected life or make money over operating costs we are a ways from breaking even on this stuff.
