The US Added More New Energy Capacity From Wind Than Any Other Source Last Year (cnbc.com) 153

Last year, 42% of new electricity generation capacity in the U.S. came from land-based wind energy -- more than from any other source -- according to numbers in a series of reports from the Department of Energy (DOE) this week. By contrast, solar amounted to only 38% of new capacity last year. CNBC reports: While both capacity and electricity generation from wind can vary regionally, land-based wind is now a strong, intermittent energy source across the U.S. According to research by DOE's Lawrence Berkeley National Laboratory, a record 16,836 megawatts of new utility-scale land-based wind power capacity was added to U.S. energy infrastructure in 2020, representing about $24.6 billion of investment in new wind power. Last year, the DOE noted, wind energy was able to provide more than half of in-state electricity generation and sales in a few states. Iowa led the pack with wind power providing 57% of its in-state electricity generation. However, Iowa has a lot of wind turbines, and not a very big population.

The growth of land-based wind energy in the U.S. last year was driven partly by production tax credits that are poised for a phaseout, encouraging development before that event horizon. Wind technology improvements also helped encourage land-based wind development. Compared to older wind turbines, the latest models feature taller towers with longer blades that can produce more energy by reaching into higher winds. In addition to land-based wind farms, myriad off-shore wind developments are underway domestically. But last year, off-shore wind farms still weren't operational across most of the U.S. The DOE's 2021 Offshore Wind Market Report instead focuses on the "pipeline" of offshore initiatives. In 2020, the offshore pipeline "grew to a potential generating capacity of 35,324 megawatts (MW)," a 24% increase from the prior year, that report says.

    With more and more of our electricity generation coming from renewable sources, how come the prices we are charged for electricity continue to rise at an alarming rate?

    As more and more generation swings across to those sources, the cost-per-unit to the providers drops. So why is it OK for the providers to just take fatter and fatter profit margins?

    A common response to this challenge is to point out that solar panels and wind turbines don't appear by magic and that they cost money to build and run. Which is true, but which is also misdirection at best and outright specious at worst.

    Renewables by definition don't incur costs for the fuel on an on-going basis. And for the cost of one fossil-fuel-powered generating station, it should be possible to build several good-sized factories capable of churning out either solar panels or wind turbines.

    This is starting to smell a lot like wholesale market abuse.

      With more and more of our electricity generation coming from renewable sources, how come the prices we are charged for electricity continue to rise at an alarming rate?

      Are they? US electricity prices are still extremely low compared to other developed countries.

      Part of this is that you are not paying for "externalities", that is the damage caused by carbon emissions.
      If there was a sensible carbon tax, then the benefits of nuclear and renewables would be reflected somewhat in your energy bills.

        True, but it does vary regionally. California is increasing very rapidly, and a lot of that has to do with the wildfire issues... but the costs associated with integrating batteries and a host of other measures they are taking are certainly also driving up costs. In truth the wholesale price isn't capturing the costs of the massive amount of subsidies that flow into the industry.

        Agreed, but those costs pale to near-insignificance when compared with the cost of:-

        1. Running surveys to find remaining reserves of oil and gas
        2. Constructing off-shore oil rigs to retrieve it
        3. Laying pipelines or having tankers collect the crude from the mine head
        4. Transporting the crude oil to a refinery, or piping the gas on-shore
        5. Designing, building, operating and maintaining a refinery
        6. Transporting the energy to the point where it is going to be used to generate electricity
        7. Maintaining the turbines of the electrical generating stations
        8. All of which require far more infrastructure and personnel than solar panel or wind turbine manufacture and maintenance.

        These are recurring, on-going costs. Stop the fossil fuel supply: no more electricity. On the other hand:-

        1. Build solar panel
        2. Transport solar panel to deployment site
        3. Deploy and connect solar panel
        4. Occasionally clean panel (of i.e. dust, dirt, bird lime)

      Renewables by definition don't incur costs for the fuel on an on-going basis.

      This is not an accurate statement. Wind turbines require upkeep. Solar installations, biomass, and geothermal also require upkeep. This is how you end up with more people needing to work in the renewable field than those who work in non-renewable energy production.

      The manufacturer of the turbines says they'll last about 25 years (5 year warranty).

      Based on that, you can either:

      A) Use your savings to put up one wind turbine, which provides power to a few houses when the wind is right

      B) Borrow $50 million from the bank (or via bonds) for 20 years and build a big wind farm

      97% of the wind capacity is option B. Large wind farms, built with borrowed money. Money that gets paid back on monthly payments for the next 20 years.

        So, after 20 years, assuming no changes in electricity prices (which will likely go up) or cost to install new turbines (which will likely go down), you'd have paid off the cost of your wind farm and mad enough money to replace it... and build a second or third one just like it.

    • > Renewables by definition don't incur costs for the fuel on an on-going basis.

      You might want to look up the definition of renewable.
      It actually means it DOES continue on an ongoing basis.
      For example, biodiesel is a renewable fuel BECAUSE you can continue to produce it on an ongoing basis.

      A non-renewable fuel, such as oil, is one that you can NOT keep making. It's one that we have a certain amount of, as opposed to one that's made on an ongoing basis.

      You are missing the point. As I see it, the real point of such energy research and development is not to get free or even necessarily inexpensive energy to consumers, it is to utilize energy sources that will not run out for as long as we are on this planet, and whose usage does not adversely impact its habitability. Making it cheap is really more about encouraging people to adopt it in the first place more than it a reflection that it necessarily should be inexpensive.

        Onshore wind capacity factor is about 0.25. Offshore wind can get to about 0.4, skewed high by the most consistent areas (off Scotland and Spain which can get over 0.65). But it's highly dependent on geography. At the latitude of the U.S./Canada and EU, the prevailing winds are from the West, which makes the best spots for offshore wind the west coast. Europe is blessed with a huge continental shelf along its west coast upon which you can build wind. You can go 100 km offshore and still be in less than 50 meters of water. The entire North Sea is less than 150 m deep.

        But the U.S. west coast mostly just drops off, reaching over a km deep just a few km offshore. The best spot for offshore wind in the U.S. is just under Connecticut, Rhode Island, and Massachusetts - where the coastline runs nearly directly East-West. The U.S. East coast has a large continental shelf where depths are only about 200m, and that area gives the winds a long stretch of uninterrupted ocean to pick up speed. Unfortunately that's the offshore wind project the rich folks on Martha's Vineyard keep blocking.

        Solar capacity factor for the continental U.S. is about 0.145. Ranging from about 0.1 in the northern states, to 0.19 in the desert southwest. Most of the solar buildout is likely in this region. You can enter your zip code into the PWatts site [nrel.gov] to see what it is for your neighborhood. Just type in any numbers - the summary page at the end lists capacity factor each month. (Concentrated solar, which uses mirrors to concentrate sunlight, for some reason uses the surface area of the receiver rather than the mirrors to calculate capacity factor. So you'll see higher capacity factors for it. Rest assured that nothing can cause the sun to shine more than about 750 W/m^2 at sea level during noon on a sunny day.)

        Hydro, gas, and coal are about 0.5. But that's mostly because they're shut off when demand decreases. (In hydro's case, its annual generation is limited by annual rainfall.)

        Nuclear is around 0.9. It's quick to ramp up, but very slow to ramp down (fission products continue decaying and releasing heat, even if you've halted any additional uranium from fissioning). So they typically run nuclear plants at full power year round, taking them offline only for maintenance.

        So 1 MW of nuclear capacity = 1.8 MW of hydro, coal, or gas capacity = 3.6 MW of onshore wind capacity = 4.7 MW of PV solar capacity in the desert SW = 9 MW of PV solar solar capacity in northern states.
        • Thanks for summarizing all of this. I think this is why the headline is definitely misleading/fakery. Capacity is capacity, sure, but then bundling all the sources together is pointless. Sure renewables might be 45% of installed capacity, but like 10% of actual generation which is what actually matters.

            It looks like you are off by half. The US actually generates 20% of its electricity from renewable sources.

        Oddly the most long-lived light bulb I ever owned was a CFL. I actually had it in the range hood over the stove, and undervolted it many times by accidentally flipping the switch the wrong way, and it survived all the abuse including the thermal swings. And it wasn't a very expensive CFL either, I think it came out

    • Welcome to externalities. You're learning the lesson that isn't being applied to power generation.
      Power generators aren't being charged the cost of the environment as an externality.
      You however are being charged the externality of supporting and maintaining your grid connection.

      It sucks. But that's the way the cookie crumbles. Mind you that externality doesn't cost you more if you use less.

    I've been thinking about the nature of the polarization many of these discussions about where our energy sources come from. I found key concepts in a book called "Overshoot" that put the polarization into perspective. I thought I'd share an idea that I found makes it easier to put all this stuff into perspective.

    Putting aside the "what" and "where" of the energy source, considering "when" the energy was captured leads to the obvious fact that all our energy supplies are solar.

    Our entire society is built upon using energy that was captured millions of years ago when drawn from coal or nuclear. It's still solar power even if it is nuclear because even those heavy elements were created from a star. This means our society is drawing on energy that was created in the past encapsulated in a concept called "Antique Energy".

    Wind, geothermal, wave and solar energy are also Solar energy. The key difference is these energy sources are drawn from the present in the environment encapsulated in a concept called "Contemporary Energy".

    To reframe the core concepts surrounding the discussions about the changes our energy supplies are making, the transition from Antique Energy to Contemporary Energy becomes a discussion about if we are adaptable and ingenious enough to do so. To me the technological challenges we face to make this transition are really exciting and interesting and the questions about "why" are simpler to answer leaving only an evaluation of "how".

    My concern is being able to make the transition whilst it is still possible for us to use "Antique Energy". Any discussion about continued use of Antique Energy is avoiding the most unacknowledged fact that it remains an exhaustible resource and therefore is a limiting factor that threatens our society.

    Contemporary Energy may lead to a less energetic society as we adapt and whilst the argument has been made that it means we will live in caves I'd point out that we are still hunters and gatherers for Coal, Oil and uranium reserves whilst we use Antique energy. To me use of Contemporary Energy shows we are willing to solve the problems that transmute those limiting factors from unsolvable resources issues into technological issues that human beings have demonstrated a constant ability to solve.

      There's no need for you to invent new terminology. We have sustainable and unsustainable sources, and that frankly will do. Fossil fuels are unsustainable both because we will run out of them and because when we burn them we perturb the system upon which we depend for life support. And frankly, the latter factor both far outweighs the former, and is coming to a head far sooner, to the point that it's really not even worth talking about what happens when we deplete them. If we actually managed to do that, we

        I agree that fossil fuels are unsustainable, I think the terms are important because there is an argument around what constitutes sustainable. You have not included nuclear in your rationale and many would argue that it is sustainable.

        However there is no argument around "when" the energy was captured and that clear distinction leads to thoughts about energy density and a clearer definition of the processes required to extract the en

    • Your discussion is an interesting thought exercise, but I do not believe that the available supply of antique energy is going to be the limiting factor. The external costs of burning fossil fuel are going to catch up with us before we exhaust the sources. We have been doing a great job of becoming more efficient and burning the fuel, at finding the fuel, at extracting the fuel. We know about vast deposits that remain untapped because they they are not cost efficient to access. But as we exhaust current fiel

        Thank you. That externality is the limiting factor I was referring to.

        The problem with our current extraction of "contemporary energy" is that it is not reliable. By that I mean we cannot access it completely on demand, as we can with antique energy.

        I think you mean that it is intermittent and the technological challenge I was referring to is to bridge that "on-demand" gap or adapt ourselves.

        By its very nature, antique energy is already stored energy. We do not have to do anything special to be able to access it when needed.

        Indeed, so the premise here is where you direct your efforts. Do you direct them to better hunter gatherer technology locating coal, uranium and oil reserves that is obviously unsustainable or do you direct them to solving the energy storage challenges that make contemporary energy more viable?

    The focus on wind vs solar seems unnecessary given that 42% ~ 38%. The important point is that 80% (42+38) of new power capacity was renewables. That's a lot! It's not surprising that power companies don't want to shut down existing power plants until end of life, but the fact the new power capacity is overwhelmingly coming from renewables is a promising sign. I didn't see it in the reports but does anyone know where hydro sits in added capacity?

    • I don't know where Hydro sits today, but the issue is that it is almost as difficult to get a new large scale dam built as it is a nuclear power plant. And it seems like we are taking more dams down than we are adding (to protect fish and restore the natural environment). Also, at least in the Western USA this year, the existing reservoirs are not generating anywhere near their theoretical capacity for power due to the fact that they do not have enough water. Perhaps a new design for reservoirs is in order,

    Many still haven't grasped this.

    With the prices of today, Solar, Wind and 4 hours of energy storage is dirt cheap. You can build 3x of this at half the price of a single nuclear power plant, at half the time it takes to build said nuclear plant. And you can bring the new electricity source in gradually - For nuclear you take 10 years to build and flip the switch for 2 GW of capacity. For Wind & Solar you linearly add 0.6 GW capacity each year. And the solar/wind/energy storage solution will have better availability and uptime than the nuclear plant.

    And here is the real kicker... By 2030, the cost of this system will be between 30-75% cheaper depending on which analyst you ask. So Solar, Wind and batteries are 1/6 the cost of Nuclear today, it will be between 1/10 to 1/25 the cost by 2030.

    • The storage/overcapacity you need to solve a polar vortex or dunkelflaute without fossil fuel is the problem. A problem which needs to be solved in a little over a decade according to government plans, unless massive amounts of air-carbon capture come online.

      Another big advantage is that wind farms can be built extremely fast. They're basically made up of prefabricated parts that are assembled on site. You can put one up in a year.

      Conventional nuclear plants take a decade to build; you're betting on what electricity prices will be in ten years. During that ten years your capital isn't making you a penny, so you have to discount your future profits by the time value of money.

    There are tax credits for wind that make building profitable. Nobody wants to miss out on the corporate tax credits, and the preferences on selling the electricity. It's a corporate welfare thing at this point, as at least in this state many are kept idle as there is an over supply but still they keep building more for the $$.

    The grid pricing here led to the grid collapse due to a lack of peaking power. The grid must have peaking power. The rules 'assume' steam power plants where you'd get built in reserve capacity, but wind and solar don't have it. The pricing needs to reflect this reality, and require wind/solar generators to pay for peaking power to go with it. In practice that means Gas power plants (experimental battery systems also work, but with teething problems).
    I've seen politicized comments about solar/wind causing the Texas winter grid collapse. That's deflection. Politician grid pricing market manipulation + 'green' pricing credits did, as they made it economically impossible to keep a historically 'normal' amount of idle capacity of peaking plants online. That's what nailed it, not the source of the power - the pricing scheme the politicians setup.
  • Wind mills are fast and easy to build.

    Other sources of electricity like hydro, coal, gas, nuclear, etc. take years, if not decades, to come on line with all the permits, environmental impact reports, NIMBY lawsuits, etc. that keep commercial power plants from even being built in some cases.

    bit of trivia, renewables, including wind and solar, account for only aprox 3% of the worlds electricity.

      correction: I forgot to include hydro electric and some less common energy sources like hydro/geothermal as "renewables" so the actual number is closer to 10-11% of the worlds electricity.
