As America's Solar Power Surges, Wind Power is Struggling (staradvertiser.com) 77

America "is now adding less wind capacity each year" than it was before the passage of a climate-protecting bill in 2022, according to the New York Times.

Since then "solar panel installations are indeed soaring to record highs in the U.S., as are batteries that can store energy for later. But wind power has struggled, both on land and in the ocean." Some factors behind the wind industry's recent slowdown may be temporary, such as snarled supply chains. But wind power is also more vulnerable than solar power to many of the biggest logistical hurdles that hinder energy projects today: a lack of transmission lines, a lengthy permitting process and a growing backlash against new projects in many communities... [M]any areas are now crowded with turbines and existing electric grids are clogged, making it difficult to add more projects. Energy companies want to expand the grid's capacity to transport even more wind power to population centers, but getting permits for transmission lines and building them has become a brutal slog that can take more than a decade... Because they can reach the height of skyscrapers, wind turbines are more noticeable than solar farms and often attract more intense opposition from local communities.

The wind industry has also been hampered by soaring equipment costs after the pandemic wrecked supply chains and inflation spiked. While those factors initially hurt solar, too, the solar industry has adjusted much faster, with China nearly doubling its manufacturing capacity for panels over the past two years. Wind supply chains, which are dominated by a few manufacturers in China, Europe and the United States, have yet to fully recover. The cost increases have been devastating for offshore wind projects in the Northeast, where developers have canceled more than half the projects they planned to build this decade. Wind isn't languishing only in the United States. While a record 117 gigawatts of new wind capacity came online last year globally, virtually all of that growth was in China. In the rest of the world, developers weren't installing wind turbines any faster than they were in 2020...

It's still possible that wind power could rebound. In fact, some experts argue that the recent slowdown is only a temporary artifact of tax policy... [John Hensley, vice president for markets and policy analysis at the American Clean Power Association, a renewable industry trade group] said that U.S. wind manufacturing was beginning to ramp up thanks to new tax incentives, while costs were starting to come down. Last year, orders for new turbines increased by 130%, although many of them won't be delivered until 2025 or later. Some states are now trying to make it easier to build renewable energy: Illinois, Michigan and Minnesota have all passed laws making it harder for local governments to restrict wind and solar. The federal government has issued new rules to accelerate the planning of transmission lines.

Demand for wind could also rise as a growing number of states, tech companies and hydrogen producers are trying to secure clean electricity around the clock, rather than just a burst of solar power in the daytime.

Many plans for moving America off fossil fuels "envision a large expansion of both solar and wind," the article points out, "because the two sources generate electricity at different hours and can complement each other. A boom in solar power alone, which runs only in daytime, isn't enough."

    Most wind potential in the US is in the great plains, while the need is in the northeast, southeast, southwest and west coast. We need to build a lot more long distance transmission lines, which people in between won't be happy about.

    Yeah, if solar "wins" the competition too much, as I've predicted in the past, this could result in day time power being cheaper than night time. This would have "implications".

    For example, the idea of charging EVs at night, when power is cheap - nope, the best time would be around 9-4 or so, depending on exact geographical region, latitude, longitude, time zone, season, daylight savings, etc...

    This means that "most" EVs you would want to charge during work instead. For commercial vehicles, the bread truck which is done delivering before noon would have it better than, say, an Amazon truck that works like 8-6. Or the postal delivery vehicle. Of course, postal delivery vehicles get so few miles that you might be able to keep them charged on lunch breaks alone.

    For air conditioning - this would be nice because the need for it is generally at its highest during the day. So go ahead - cool away.
    Note: I've always considered creating a heating/cooling "reserve" in some sort of mass object so you can keep heating/cooling even with a tiny power draw for just a fan to be an interesting thing. Create a bunch of cold/hot water, and use that instead when electricity is expensive. Doesn't even have to be water, sand or such works too.

    This is, of course, to avoid the losses and expenses of batteries as much as possible.

    But we'd still need batteries for things like the surge in power use just after sunset, when people are still up, making/eating dinner, watching TV, on the computer, etc...

    • The heat/cool reserve isn't as efficient as it sounds. The useful energy stored is proportional to the thermal mass times the amount hotter or colder than your house the bank is. That means that to charge it up you have to push heat against a steeper gradient then you would have to to directly heat/cool the home. Consider that an air conditioner is typically pushing against a thermal gradient of just 10 or 20 degrees Celsius. If you double that so that you can chill the store near zero so you have enough of

        Consider that an air conditioner is typically pushing against a thermal gradient of just 10 or 20 degrees Celsius.

        In order for the heat exchangers (coils) to move heat, there have to be decent temperature differences between the refrigerant temperature and the temperatures of supply air (around 14C) and ambient outside air (typically rated at 35C). So, for a typical air-cooled home A/C, the temperature difference between the refrigerant entering the evaporator (5C to 10C) and the refrigerant entering the

    • So called "thermal energy storage" systems(typically some variation on a tank of water or brine with heat exchanger piping and insulation that can be brought down below freezing to fill with ice off-peak; then melted to cool refrigerant during demand hours) have been a thing for quite some time. Even in cases where you aren't paying different electrical rates at different times of day they can be attractive for larger installs because you can go with a lower capacity cooling system, just enough to cope with
      • Storing heat is trivial, but more infrastructure install. Sand thermal batteries are up to 95% energy efficient and can store that heat for *months*. linky [bbc.com]

        Scaling to personal residence level is a bit trickier to retro fit, but conceptually building the sand storage into a foundation or garage floor would be perfect for new construction.

        Converting that heat back to electricity is less efficient but still possible. As with any renewable, fuel free, source, the only cost is one time infrastructure to
      • Storing heat is very easy. There are many, many houses in the UK that use storage heaters -- they take advantage of cheap electricity at night to heat up bricks and then extract the heat from the bricks during the day. If a house in the UK does not have a natural gas supply, it's very likely to use storage heaters, although the UK is now strongly pushing heat pumps.

        While most of these use individual room heaters (probably multiple per room), the first house I owned had a heating system with a central stored

    • Renewables require battery storage of some sort.

      The real golden scenario is to use the EV batteries as night time power sources, charged whenever. The size of EV batteries for all cars will *dwarf* the size of batteries we need to run the rest of the grid. 2-4x more in EV battery sizes.

      But realistically, we probably need battery storage at/near the commercial solar plants to handle the day time over supply and deliver that through the night.
      • The storage is now getting built at a rapid pace. Up to a certain point, renewables can be used whenever they run. But once past 20-30% there will be times they over-produce, and the excess gets wasted. California reached that point a few years ago, and started installing lots of battery farms. Now they can time-shift mid-day sun to early evening when peak load in the summer happens.

        • Yep. Commercial solar plants actually curtail by design. If they want a 100MW plant they actually build to produce 130+. That way the time spent at rated 100 is longer. Once we can store that mid day excess more fully things get really really cheap lol

      This is how it works here in my state in Australia. We regularly have negative power prices in the middle of the day due to surplus from (mostly) solar.

      People with batteries can charge and use it later - or, as is becoming slowly more common, sell it back to the grid at a significant profit later in peak hours. It's almost like a proper market now!

I'm pretty certain Dutton accepts that advice and has no intention of letting a nuclear power plant being built, let alone funding the build with government money. If you listen carefully to what the opposition says, that comes out between the lines. For example they say over and over again they will not build a plant

      • What's isn't "maybe" is the effect renewables have on economics of nuclear. Before renewables came along, you when you built a plant and you had an almost guaranteed income stream for 24 hours a day. Now solar removes 1/3 of your sales during the day. That happens right now where I live now. If households install a battery to get them through peak hour, then in the future you're going to lose another 1/3 of a day. The remaining 1/3 is in the small hours of the morning when consumption is smallest. If nuclear sells it's power for 24 hours a day, it pays back it's debt in 20 years and makes enough money for the next 30 to pay for it's decommissioning and a profit. 20 years ago being about sell power 24 hours a day looked like a pretty sure bet. Now for 1/3 of that time the market may charge you for dumping the power into a grid that's already oversupplied because you can't follow the load fast enough. Nuclear can't follow even follow the normal functions in load that occur over the course of a day. My how times have changed.

        You're victim to a couple of common misconceptions. For one, nuclear power can load follow, even reactors that aren't explicitly built for it. It's done in several facilities in the US, with the savings being reduced fuel burnup. Why it isn't commonly done is most of the costs of a nuclear facility are sunk. The actual running of the plant is a pittance cost-wise, and as such power prices have to be very low or even negative to justify reduced output. But if a utility has, say, a state mandate to hit some a

          As is all too often pointed out. Solar only works during the daytime. Wind may in fact be intermittent, but it's usually blowing somewhere and excess wind power can charge batteries just as easily as excess solar power.

          Given my druthers, however, I'd really like to see a focus on developing and building out tidal power and deep geothermal, both which would provide a near constant source of power.

      OK, let's put a nuclear power plant in your backyard

      Or maybe coasties should pay through the nose for their "great weather" and seaside amenities, all while expecting the rest of the country to feed, power, and water them. .

  • due to the amount of hot air generated by the election.

  • Are we using so much power now that the wind turbines are actually going backwards, making wind?
  • What is NIMBY? NIMBY is really YIYBY, yes in YOUR back yard. Everyone is real quick to want something put in SOMEONE ELSE'S back yard, and if the someone else takes exception, then they smear them as NIMBYs. Almost as good a smear as "racist."

    • That's the problem everyone has with NIMBY's though, they usually are in fact dictating what other people can do with their property. If a bunch of people get a developer to stop work on housing projects what is that but a bunch of people saying what a property owner can do with their lot. Zoning laws are just that sentiment written into law.

      If your neighbor want's to sell their lot to a developer who want's to replace it with a quadplex, do you have some sort of right to stop that action if it's legally

      I thought the term was coined for people who were actively, politically pushing for some infrastructure and turned into vehement opposition the moment the project considered their vicinity for said infrastructure.

      Unfortunately, "backyard" all too often expands from backyard to neighborhood, town, city, county, and state. Witness the number of people who were complaining about offshore wind... when it wasn't, in fact, on their land or property at all.

    • I suggest that you listen to a recent episode of the Reveal podcast:
      https://revealnews.org/podcast... [revealnews.org]

      This discusses how residents of one town are NIYBYs (Not In Your Back Yard).

  • The booming solar is thousands of individual households putting up a few kilowatts of panels, whereas residential scale wind for electricity generation has never been that popular. It's kind of the other way around with grid scale projects. I see and read of wind turbines all over the place but only a few grid scale solar projects in the southwest. For individual households, the appeal of DIY, and personal desire to improve the environment are part of the decision making process, and the permitting, ener
  • That the cheapest way to get decent Solar is... to rent a uhaul, pop off to a solar farm, and then pinch a dozen or so panels.
  • To have a reliable power generation system using only wind, storage needs to cover calm periods of days due to high pressure weather systems, when generation will fall to a few percent of faceplate, and also whole seasons with very low winds.

    The UK Royal Society considered the actual historical weather of the UK. It estimated that the UK would require 100 TWh of storage for a system with peak demand of 45+ GW. This was to go to a system using only wind and solar. [Put it another way: you have to be able
