Great Britain's Electricity System Has Greenest Day Ever Over Easter (theguardian.com) 128

An anonymous reader quotes a report from The Guardian: Great Britain's electricity system recorded its greenest ever day over the Easter bank holiday as sunshine and windy weather led to a surge in renewable energy. The power plants generating electricity in England, Scotland and Wales produced only 39g of carbon dioxide for every kilowatt-hour of electricity on Monday, according to National Grid's electricity system operator, the lowest carbon intensity recorded since National Grid records began in 1935.

On Easter Monday, wind turbines and solar farms generated 60% of all electricity as households enjoyed a bank holiday lunch. At the same time the UK's nuclear reactors provided 16% of the electricity mix, meaning almost 80% of the grid was powered from low-carbon sources. The low-carbon power surge, combined with lower than average demand for electricity over the bank holiday, kept gas-fired power in Great Britain to 10% of the electricity mix and caused the "carbon intensity" of the electricity system to plummet to its lowest on record.

      Everyone being broke is a good way to save power as well. "The UK GDP fell 7.3 percent year-on-year in the last three months of 2020, less than preliminary estimates of a 7.8 percent fall. Business investment fell much less than initially estimated (-7.4 percent vs -10.3 percent) and the drop for both exports (-18.9 percent vs -23.5 percent in the preliminary estimate) and imports (-4.7 percent vs -8.9 percent) was revised lower. On the other hand, household spending fell 9.2 percent, the same as in the preliminary estimate. The contraction for 2020 was also revised to 9.8%, from the first estimate of a 9.9% decline. source: Office for National Statistics"

        The UK has the worst economic hit in the G7 from COVID. Our economy is badly damaged, with brexit also causing long term irreversible decline.

        It will be interesting, in a somewhat morbid sense, to see how energy consumption is affected by a former major economy sliding into irrelevance and stagnation.

            Even if we re-joined say the EEA tomorrow much of the damage is done. Businesses have moved away and won't come back. New trade routes bypassing the UK are up and running. A lot of the skilled workers we need have left and won't return.

            The hit we have taken can't be simply undone, it's with us forever now. Even when the economy finally starts to grow again it will be from a lower starting point, so to reverse the damage it would have to experience an equal benefit from brexit and that seems extremely unlikely to happen. The opportunities simply aren't there, given that we need to replace the premium access we had to the EU and the only other blocs of comparable size are the US and China, neither of which would give us such a deal and even if they did it wouldn't benefit us like the EU one did.

    Here's an article by Dr. Ripu Malhotra, with some very interesting data from government sources telling us that the UK would have had lower CO2 emissions if they had placed greater emphasis on nuclear power.
    https://cmo-ripu.blogspot.com/... [blogspot.com]

    I know someone is going to come back with "but nuclear power costs too much, so take that!" Okay then, how much is too much to spend on lowering CO2? Come up with a number. Please. Because I want to know just how much value you place on lowering CO2 to avoid global warming. I suspect that if this math was done then solar power would lose out to natural gas. The level of materials needed for solar power to create the same energy and power as nuclear fission is at least two orders of magnitude. I'll see people claim that this can be improved with new technologies. You know what can also be improved with new technologies? The cost in time and materials for nuclear power.

    Solar power is shit for electricity to the grid. It is a waste of time and materials. More people die from solar power on a per MWh basis than nuclear fission. That's on a global scale when taking into account the disasters outside of the UK. Nuclear power in the UK, USA, Canada, France, Germany, and so many other nations outside of the old Soviet nations is just incredible. By incredible I mean people are incredulous, cannot grasp in their minds, just how safe nuclear fission power has been. We know how to build it safer now, at lower costs, and with less materials.

    The costs overruns we see now in nuclear power has come from NIMBYs and BANANAs. ( https://en.wikipedia.org/wiki/... [wikipedia.org] ) The costs come from inexperience. These were the same kinds of costs overruns that came from early wind and solar power projects. Costs that solar power still has not brought to be competitive with coal, nuclear, natural gas, wind, hydro, and so much else we have to choose from. Solar power is shit for power on the grid and we'd be better served to put those resources into energy sources that are lower cost and lower in CO2 emissions.

    With hydro, onshore wind, geothermal, and nuclear fission we can get CO2 emissions lower than this record set by Great Britain, and do it EVERY DAY.

    Solar power is dragging down the average and holding us back from doing better. It costs too much, it takes too much time/materials/resources, it's actually not all that safe (people falling off roofs, electrocutions, and other industrial accidents), not that great in CO2 emissions, and very unreliable. As a source of electricity on the grid this makes a very very bad idea.

    If someone wants to put solar panels on their roof then I'm not going to stop them. I think it's idiotic, a potential environmental disaster, a matter more of conspicuous consumption than anything practical. I just don't want my taxes subsidizing this. This is a waste of tax money because we have better options on lowering CO2 emissions, lowering energy costs, lowering human suffering, and generally making a better world for ourselves.

    Great Britain can do better than this. They should consider this new record a ceiling for CO2 emissions in the future. A ceiling that they can stay under with a combination of hydro, onshore wind, geothermal, and most importantly nuclear fission. Without nuclear fission they will not ever see another day of CO2 emissions this low.

    • Without nuclear fission they will not ever see another day of CO2 emissions this low.

    • by Ichijo ( 607641 )

      Solar power is...very unreliable.

      So is electrical demand. It goes up and down throughout the day, forcing electrical utilities to forecast demand and bring up more and more expensive sources of power throughout the day as demand rises, then power down those generators later in the day as demand falls. Since we can easily forecast solar output, it's no problem to bring it onto the grid, at least until peak output reaches well over 50% of the total energy mix.

      • Indeed, solar power output can be predicted but that doesn't make it reliable. That is unless you consider something that can be relied upon to fail as reliable.

        Solar power is far from "no problem" on the grid. Having studied electrical engineering at university and listening to people in the energy industry I know that solar power on the grid is a problem long before it reaches 50% of the total electric generating capacity. The industry treats rooftop solar like a "negative load". It shows on their cal

              Are you lying or do you have proof? Because as far as I know, this only became a problem in South Australia where peak solar output peaks at around 100%, so they stabilized the grid with Tesla batteries [slashdot.org].

              So where's your proof that the problem occurs "far closer to 5%"? Let your next post contain that proof, or don't bother replying at all.

As if nobody has ever been injured due to nuclear accidents or electrocuted at a substation. Go ahead and find me some solar panel death numbers. I'll keep checking back.
