America's Renewables Surpassed Coal in 2022 - But Greenhouse Gas Emissions Still Increased (chicagotribune.com) 91

Last year in America, "Renewable energy surpassed coal power nationwide for the first time in over six decades," reports the New York Times. Wind, solar and hydropower generated 22% of America's electricity, compared with 20% from coal.

But unfortunately, America's greenhouse gas emissions still increased from the year before, "according to preliminary estimates published Tuesday by the Rhodium Group, a nonpartisan research firm."

The New Yorker supplies some context: This increase, according to the report, "was driven mainly by the demand for jet fuel," as air travel rebounded from COVID levels, and it might have been even larger but for the war in Ukraine, which drove up fuel prices....

As part of the Paris Agreement, the U.S. pledged to reduce its emissions by half by 2030, using 2005 as a baseline. Emissions are now down only around fifteen per cent compared with 2005, which leaves a thirty-five-per-cent cut to be implemented in just eight years. Last summer's passage of the Inflation Reduction Act, which authorizes some four hundred billion dollars' worth of spending on clean energy, was a "turning point," the Rhodium Group said, and could produce emissions cuts "as early as this year if the government can fast-track implementation." Still, the group admonished, the U.S. "needs to significantly increase its efforts."

      I'm actually kind of surprised we're already about 1/3 of the way to the goal. I do see a lot more solar and wind fields now, but on a personal level I can't say I've felt any pain or really done anything. Electric cars are just now ramping up and I am looking forward to replacing our commuter car with one once pricing and availability improve, and I do see that happening.

        I spent about ten years working in the environmental non-profit sector. This was during the transition from what I would characterize as Crying Indian [youtube.com] environmentalism to framing environmentalism in terms of "sustainability". Being a contrarian by nature, I saw a logical problem with this new framing: isn't non-sustainability a self-correcting problem?

        The problem isn't that you can't burn petroleum forever. The problem is the consequences of burning fossil fuels until you're literally forced to stop. And although many people have been trained to have a visceral distaste for the world "justice", fairness is a valid concern because those consequences aren't shared equally.

        If coffee ends up costing $100/lb, you and I won't be drinking it any more but the petro-billionaires of Dubai will still have plenty. If a new normal of drought makes an American rancher's spread unproductive, the rancher is out of luck but agribusiness will simply source cattle elsewhere. If temperatures in Delhi start hitting 50C/122F routinely, some people will cocoon themselves in air conditioning but the two an a quarter million below the $2400/yr poverty line there will just have to suffer.

        In other words, I think sustainability is in the eye of the beholder; one man's environmental catastrophe is another man's chance to make a buck. So yeah, fairness is really an issue here.

    Right here is the problem all over. We CANNOT allow our direction to change. We have been on right path, but over last year, went in wrong direction.
    We need to do several things:
    1) convert coal plants to nat gas, with ability to add nuclear reactors. This way, it drops our emissions, but also allows 2 different sources of heat
    2) build new nuclear SMR as fast as possible. NuScale can, and needs, to be sped up. Also, we need new fast SMRs that can finish the nuclear cycle
    3) tax consumed goods /services based on where the worst part comes from. It should not matter how much the part, just what nation/state it comes from. Use satellites to measure the areas, and normalize based on emissions / $GDP ( real ).

    They will keep on being puzzled by this, and they will keep on adding intermittent and unreliable generation to the grid to try to lower emissions, and emissions will continue to rise.

    Why is this? Because intermittency. You install a higher and higher percentage of total grid capacity from unreliable and intermittent sources. This is called 'overbuilding'. You end up installing double or triple the amount of peak capacity you need to meet demand. But the sun still sets, it still produces very little and then sharply peaked in winter, and there are still long high pressure periods when the wind hardly does anything.

    You could see this happening in the UK last summer, and also in early winter 2022. There were periods when a total installed base of wind and solar amounting to 40GW (which is about the average UK demand) produced only 1GW. And quite long periods when it produced less than 4GW.

    I know people will not believe this, so look here for the facts:

    www.gridwatch.co.uk
    www.gridwatch.templar.co.uk

    So you might think that even so, emissions will be reduced, because for the rest of the time we are not burning fuel. Well no, you'd be wrong. Because you are running the plant in backup and rapid start mode, so you increase emissions per unit of generation.

    The whole policy the West is currently following will in fact result in both higher prices for electricity and higher emissions. The reason is, it will raise the demand for electricity for EVs and heat pumps etc. In order to try and meet this raised and existing demand there will have to be massive overbuild of wind and solar. But this will require equally massive backup systems to cope with intermittency, whose structure will not have changed. And which will be working in the most inefficient way.

    Meanwhile, the capacity factor of the renewables will actually fall. Because as you overbuild, there will be higher and higher percentages of time when they are producing more power than can be used, and absent storage it will be wasted. So the practical capacity factor, already around 30%, will fall.

    This will all be prodigiously expensive, and one of the sources of the expense is the installation of extra transmission facilities to move the power to where it will be consumed. So prices will rise.

    Again, look at the UK. Its the canary in the coal mine. The current plans for upgrading the transmission network are hugely expensive.

    And as a consumer, consider the fact that at the moment it costs more in the UK to refuel an EV than an ICE one. Astonishing, isn't it? You increase demand, you take out your reliable consistent supply and replace it with intermittent and unreliable, and prices rise and the threat of blackouts rises.

    Whoever could have foreseen anything like this, when all we were trying to do was save the planet. Along with China and India, who are also supposedly busy trying to save the planet. But in rather different ways!

      Unfortunately, your information is at best out of date (and at worst, superficial)

      They will keep on being puzzled by this, and they will keep on adding intermittent and unreliable generation to the grid to try to lower emissions, and emissions will continue to rise. Why is this? Because intermittency.

      Nope. As a quick simplification of a complex optimization, every joule that renewable sources add to the grid is one joule not produced by fossil-fuel sources EXCEPT power produced from about midnight to 7am, which tends to be of little use because demand is very low.

      Solar peaks during the daytime, which is fine. Solar power supplants fossil fuels very well. (Wind... wind power produced during those hours is basically not contributing. So, as a quick approximation, yes, about 1/3 of wind power production is not at a useful time).

      You install a higher and higher percentage of total grid capacity from unreliable and intermittent sources. This is called 'overbuilding'.

      Wait, wait! Suddenly you are talking about something completely different-- overcapacity. But we were talking about carbon-dioxide emission. Overcapacity is too complicated a subject to really analyze in depth in a slashdot post, but for the current discussion, the critical point is that if a modern fossil-fuel plant isn't producing power, it's not emitting carbon dioxide.

      ...So you might think that even so, emissions will be reduced, because for the rest of the time we are not burning fuel. Well no, you'd be wrong.

      No, you'd be right. Modern gas-turbine power plants spin up very quickly. If you don't want power, you don't burn fuel.

      Because you are running the plant in backup and rapid start mode, so you increase emissions per unit of generation.

      Are you living in the 1960s? Maybe true for old coal plants, but modern gas turbine power plants spin up very quickly. If you don't need power, you don't burn fuel.

      And the supply and demand curves don't have abrupt changes (that's a different problem). You don't need rapid start; you ramp up and down at reasonable rates.

      In fact, dealing with the supply/demand curve with intermittent sources is a tricky optimization power, and one which depends very critically on the demand curve, not just the supply curve (where "tricky" is not a synonym for "impossible".) But your blithe statement "adding intermittent sources will increase emissions" is simply wrong.

      ...Meanwhile, the capacity factor of the renewables will actually fall. Because as you overbuild, there will be higher and higher percentages of time when they are producing more power than can be used, and absent storage it will be wasted.

      First, we're talking about carbon emissions. If solar plants are producing more electricity than needed, it does not increase carbon emissions.

      Second, we are far from that status. By the time we reach that status, it's reasonable to expect some sort of buffering will be online-- batteries, pumped hydro storage, flywheel energy storage, fuel cells: there are a lot of technologies out there which can be implemented.

      • " power produced from about midnight to 7am, which tends to be of little use because demand is very low. "

    It seems that everyone who believes there is a climate crisis caused by human CO2 emissions also believes that moving the grids to wind and solar is a viable policy.

    Why is this? There is no logical connexion between the two. They are logically independent. It is a perfectly consistent position to be persuaded there is an emergency, but also to believe it to be impossible to run a modern industrial economy off a grid powered by wind and solar.

    So why does all serious scrutiny of the merits of wind and solar get called climate denialism? Its nothing of the sort, its just rational scrutiny of the merits of wind and solar, and the experience of all the countries who have tried it, Germany, the UK, Australia, and now the US, is that you cannot lower emissions by installing it. If you want a reliable and usable grid, adding wind and solar to your existing conventional and nuclear one will actually raise emissions, because of the other changes you have to make in order to accommodate it. There is no country which has lowered its emissions by installing wind and solar. Nor is there any country which has lowered its electricity costs - in fact the correlation is the other way, the more renewables, the higher the cost of power.

    This is what is happening in the world. Whether there is a climate crisis, emergency or not due to human emissions is immaterial. This is not going to solve it.

      I'm skeptical of 100% renewable right now (unless you have shitloads of hydro or thermal) but even with shitty capacity factors you can definitely reduce average emissions. Whether or not it's the best ROI is another matter and depends on the existing grid, insolation, etc.

        Maybe at very low levels of penetration it might be possible. But not when you get to the scale of the UK or Germany's installations of wind and solar. Isn't happening.
