Wind is Main Source of UK Electricity for First Time (bbc.com) 97

Wind turbines have generated more electricity than gas for the first time in the UK. From a report: In the first three months of this year a third of the country's electricity came from wind farms, research from Imperial College London have shown. National Grid has also confirmed that April saw a record period of solar energy generation. By 2035 the UK aims for all of its electricity to have net zero emissions. "There are still many hurdles to reaching a completely fossil fuel-free grid, but wind out-supplying gas for the first time is a genuine milestone event," said Iain Staffell, energy researcher at Imperial College and lead author of the report. The majority of the UK's wind power has come from offshore wind farms. Installing new onshore wind turbines has effectively been banned since 2015 in England.

  • Even though electricity from wind is cheaper to produce they sell it for the price of gas and pocket the difference. Also trying to become more energy efficent gets you punished with higher standing charges.

      You need to be more specific about who "they" is that is charging you.

      It isn't "they" (the ones who own solar or wind farms charging you the same price -- that's your electric company who can buy electricity from renewable sources.

      Where I live, if you power your own house with your own solar, you get charged *0* and may be charged less than zero if you generate a surplus that is fed back into the grid. You get paid the Kw-h rate to feed electricity into the grid. Which means you can substantially reduce

        There's no feed in tariff for new installations.
      • It is the solar and wind farms charging it, because of the way the electricity market works.
        Every half hour, generators submit bids for price and amount of electricity they can supply. These bids are sorted in ascending order of price, and they go down the list until they have enough electricity to meet demand. Whatever the price of the most expensive winning bid its, that is the price everyone receives.

          Maybe in some countries that's how it works, but I know in CA, it's not.

It's also the case that electricity you generate yourself is free (except for your

There are lots of interconnections with neighbouring grids.

                • Yes, and because of the interconnects it would made sense that they are/were integrated into the https://www.eex.com/en/ [eex.com] market.

                  • If you are in Spain for example, you can't buy electricity from a wind farm in Scotland. You could buy it from one of the interconnects with the British grid, and they could buy it from the Scottish wind farm. There is limited capacity on the interconnects, and they are quite often running at full capacity.

          A large wind farm takes a lot of planning and design (they are placed carefully based on underlying geography and to avoid shadowing each other based on typical wind patterns requiring modeling with CFD and weather data).

        No the issue isn't the wind farm, it's the grid itself. The UK and many parts of Europe are transmission constrained on the grid. The ability to build wind quickly doesn't matter if you can't power anything with it.

        • by q_e_t ( 5104099 )
          As noted elsewhere, from inception of the plan to build a large wind farm to the first turbine in place is likely to be at least five years as it's a significant engineering project requiring significant preparation and finance. Provided that there is an agreement to provide the grid linkage in the time period of around five years, then it won't impede a single kWh of production. Look at how long the Hornsea phases took. For a large project, five years is speedy.

    This is a good news for electricity generation. Together with nuclear and hydro, that's ~57% (42% for solar/wind and 15-16% for nuclear/hydro) of electricity generation coming from low-CO2 emitting sources.

    In terms of energy use though (which encompasses not just electricity, but all kind of energies), coal/oil/gas are still dominating at ~75%. The next challenge will be to electrify a lot of current fossil fuels usages, and the current estimate is that we will need between x2 and x3 the amount of energy we currently need if we want to do that.

    Just to compare a few countries, at the time of writing:
    - UK is emitting ~134g CO2eq / kWh [nowtricity.com] : this is pretty good!
    - Germany is emitting ~500g CO2eq / kWh [nowtricity.com] : this is because despite their communication on "huge renewables deployment", they are also closing down nuclear plants, building and burning more gas, and ~35% of their electricity generation comes from coal.
    - France is emitting ~35g CO2eq / kWh [nowtricity.com]

    • by Uecker ( 1842596 )

      Germany does not burn more gas for electricity than in the past before starting to shut down nuclear (2010: 89 TWh, 2021: 90 TWh) .
      It also uses less much coal than before (2010: 263 TWh, 2021: 165 TWh). CO2 emissions were reduced accordingly.

      It is true that they could have reduced coal much more if they hadn't shut down nuclear. But now with nuclear gone, future growth of renewables will reduce coal use much faster.

            Or in other words: If France, Germany and others had invested in renewables early on instead of nuclear, we would be much further along reducing emissions because the dramatic drop in prices would have occurred much earlier. While the investments in nuclear help reduce emissions where being used but do not matter too much in the overall scheme of things because nuclear never really become economical and therefor cannot be scaled up easily to fix the global problem.

              It doesn't look good. As I understand it, nuclear is unlikely ever to be able to compete on costs no matter how cheap and safe you make the reactor, because the high pressure steam side of the plant is more expensive than an equivalent generating capacity in solar or wind. The reactor could literally be free and it still wouldn't be able to compete on cost. That's

            Greenhouse gas effects are known since 50+ years, so it was actually a known side-effect, even if it was not the main goal.
            That said, this is even sadder: a country which didn't try hard to reduce its CO2 emissions has emitted a lot less than Germany since 50 years, which tried very hard to deploy renewables (semantics are important here: they are trying first to deploy tons of renewables, not to reduce CO2 emissions). And even now, France (and UK) are in better place than Germany...

    This isn't, by far, the first time it has happened. Wind generates more than gas on a regular basis in the UK, and has done for years.

    This will be the first time the total wind generation in a quarter exceeds gas, which is a substantially bigger achievement than claimed by the headline.

Energy is a bit like water, it's easy to take it for granted when you have running water on tap. It's when it's not easily available that its value increases significantly.
