G-7 Pledges Put Coal on Notice, Could Boost Climate Aid (apnews.com) 118

Officials from the Group of Seven wealthy nations announced Friday that they will aim to largely end greenhouse gas emissions from their power sectors by 2035, making it highly unlikely that those countries will burn coal for electricity beyond that date. From a report: Ministers from the G-7 countries meeting in Berlin also announced a target to have a "highly decarbonized road sector by 2030," meaning that electric vehicles would dominate new car sales by the end of the decade. And in a move aimed at ending the recurring conflict between rich and poor nations during international climate talks, the G-7 recognized for the first time the need to provide developing countries with additional financial aid to cope with the loss and damage caused by global warming. The agreements, which will be put to leaders next month at the G-7 summit in Elmau, Germany, were largely welcomed by climate activists. "The 2035 target for power sector decarbonisation is a real breakthrough. In practice, this means countries need to phase out coal by 2030 at the latest," said Luca Bergamaschi, director of Rome-based campaign group ECCO.

    need nuclear power to replace the coal!

    • by Klaxton ( 609696 )

      Obviously not.

    • Nope. You need something that can actually do the job in 13 years, not your fantasy solution that completely ignores the reality of every nuclear reactor we've *attempted* to build in the past 2 decades.

      • That is not how the world works. We need nuclear power plants started now because in 13 years we will have a fleet of nuclear power plants that are 13 years older with nothing to replace them.

        It is a fantasy to think we can replace nuclear power with anything but new nuclear power. Maybe we can't complete a nuclear power plant in 13 years, but that doesn't mean we should not even try.

        Those "attempted" nuclear power plants from the last 20 years are only failures if we learned nothing from the experience.

    • by AmiMoJo ( 196126 )

      They are aiming for 2035. Current new nuclear plants in Europe as taking 25 years to come online. Even the initial estimates by the developers were 20 years. So that's 2042 at best, more likely 2047. Way too late to help with this.

      It has to be something that can be built and supplying the grid in the next 13 years.

        What's actually going to happen is the purists who insist on 100% perfect and completely impractical solutions will allow energy prices and inflation to get out of hand. Then they are thrown out of the government by people who care more about putting food on the table than global warming, and finally the right wing extremists who replace them can delay any action by another decade or two.

    G7 should work to push the UN to require that all nations no longer building NEW COAL PLANTS. In addition, require that once a fossil fuel plant is shut down, that area can only open up again, as a CLEANER area. If not, then it does not get opened. So, yes, a coal plant can become a nat gas plant, but it must have LESS TOTAL EMISSIONS than the plant it replaces.

    Likewise, it is LONG past time to restart building new nuke power plants. In particular, the SMRs are a great deal cheaper and safer than the large nuke power plants.

    For the west, most nations have money saved up for nuke waste. That money should be used for NEW NUCLEAR power plants IFF it is a fast reactor that can take waste from a thermal plant, and burn it up to much lower levels. The idea of burying fuel that is only 2-3% used up, and will be around for 20-30K years is just insane.
    And yes, the reserve for nuke waste, would be IDEAL for building new plants, but only if it really burns up the waste.

    We're not going to do anything about it until we have a replacement that is more profitable. Call is going away because wind and solar and natural gas are eating its lunch. At the rate we're going wind and solar are going to eat natural gas is lunch. Does already several papers that show you can do baseload off wind and solar even in cloudy climates.

        An an example: https://en.wikipedia.org/wiki/... [wikipedia.org]. Usage per person (direct domestic use) in 2004: 7,445kWh/annum, 2017: 6,038kWh/annum. Overall use increased from about 500TWh/annum in 1990 to about 600 in 2005, and pretty much flat since, with just a very slight overall upward trend. It's a common trend certainly in Western European countries over the same period.

        Overnight, many sources of electrical power generation are not fed into the grid due to low demand, which is particularly true of things like wind. These can be harnessed in various ways, one of which is to charge electric cars. Other potential uses are to change the temperature of large thermal masses in houses (should a house have one) such as was used with electrical storage heaters in years gone by, but you can also potentially cool a thermal mass in a house in summer.

      • You go where you can fill it up in less than 5 minutes. Not go where you have to spend an hour. Electric cars are really only convenient for those that can let them charge over night where they live. Some people do value their time little enough that they are willing to put up with the inconvenience, but the vast majority of people are not BEV/alternative energy zealots.

          It's possible for apartments to build chargers in their parking lots. Not to mention we don't need 100% coverage for it to have a significant impact on gasoline use (though whether that translates to CO2 emissions reduction depends on a lot more factors).

      • by dbialac ( 320955 )
        Yep. A 2-3 minute fill up with gas is the same as a multi-hour charge with an electric. Even doing a 15 minute half charge, you're looking at a need for 5x as many chargers vs pumps to accommodate a similar number of vehicles, and you leave with half a charge.
        • by dbialac ( 320955 )
          Replying this out even further, you're going to need 10x the amount of chargers vs pumps because you also need to account for the fact that you only get 1/2 a charge in that 15 minutes.
    • I used to live in a large apartment complex. There's nowhere to put the 200+ chargers that would be needed to accommodate the people living there.

      You don't need to install "chargers" for people in this context. All you need is decent outlets, and actually even crap ones (15A@120V) will serve most people's needs if they recharge nightly. The dinky little charger that comes with the vehicle (usually, anyway — but make it their problem, not yours) is sufficient for overnight charging for typical users.

      • That nets people 24-30 miles worth of charge at best per night. Now throw in winter weather efficiency loss, people that have longer commutes, errands, etc, and that math does not work out over a week's time.

          Ah 8 hour charge should get you around 14kWh. The bigger Teslas have 90kWh. So it's about 60 miles. It's not great, but is twice your estimate.

        • Are you assuming a constant 15 amps from an outlet rated for 15 amps? Do that and you will eventually trip the circuit breaker. That 15 amp outlet rating is a peak rating. When pulling current for many hours that 15 amp outlet should only supply something like 10 amps, maybe 12 or 13 amps, depending on how one does the math and who's safety derate tables are used.

          There are rules on outlets for charging EVs, and they are not cheap to install. There must be a dedicated circuit breaker. There's going to h

      Electric vehicles are generally cheaper to produce than gas powered ones because they're mechanically simpler. They're more expensive currently because they're made in smaller numbers and because of their batteries. Battery cost is decreasing exponentially.

      As for how to charge your electric car, just run an electric wire through the gasoline pipe that currently serves your parking spot.

      • Battery cost is decreasing exponentially.

        Sure, that happens when electric vehicles are one percent of the total market and the batteries used in cars make up a fraction of the total demand for batteries. What happens to the price of the raw materials to make these batteries when the demand goes up by 100 times?

        We will not continue to see battery costs decrease exponentially, at some point the costs run into the problem of just paying for the raw materials. Just consider how much more valuable a working gasoline car is compared to the scrap metal

              • Algae bioreactors to sequester carbon are still processes power by sunlight. This limits how much CO2 that can be sequestered to the power of sunlight gathered, which will always be limited, and the efficiency of the algae to convert CO2 into some liquid or solid that we could handle. How efficient can this algae be?
