Renewable Energy Growth Must Speed Up To Meet Paris Goals, Agency Says (theguardian.com) 195

An anonymous reader quotes a report from The Guardian: Renewable electricity production needs to grow eight times faster than the current rate to help limit global heating, according to a report. The International Renewable Energy Agency (Irena) said urgent action was needed to keep pace with rising demand for electricity, which could require a total investment of $131 trillion in renewables by 2050. Francesco La Camera, the director general of Irena, said the "window of opportunity" to achieve the goals of the Paris climate agreement was closing fast. "The recent trends show that the gap between where we are and where we should be is not decreasing but widening. We are heading in the wrong direction," La Camera said. "We need a drastic acceleration of energy transitions to make a meaningful turnaround. Time will be the most important variable to measure our efforts."

The agency's outlook report says keeping a lid on rising temperatures will require electricity to surpass fossil fuels as the dominant source of energy before 2050, as more economies electrify transport and heating to help cut carbon emissions. Clean electricity will also be in high demand to produce "green hydrogen" to burn in heavy industry and manufacturing plants where direct electrification is not possible. The surge in electricity use could mean that electric power will make up just over half of all energy consumed by 2050, compared with 21% in 2018. Fossil fuels have made up almost two-thirds of energy consumption in recent years but may be reduced to 10% by 2050.

    Nuclear power is the one cheap CO2 free source we can make happen all around the globe quickly for a large amount of power produced, at this point the plants are well-understood and quite safe.

      • Nuclear power and renewable power are mutually antagonistic.

        You can't shut off a nuclear power station easily, and you can only throttle them down so much. It's also stupidly expensive, meaning you want to run a nuclear plant at 100% capacity as much as possible to earn every cent you can during the plant's operational life to get back the cost of building and operating it.

        Most renewables are inexpensive to install and very inexpensive to operate. Sunlight and wind are free, so once you cover the cost of co

        • Plus you can maybe reduce their output by 40% or so with modern designs, and it can take hours to modulate the output up and down.

          Note, for the record, that nuclear submarines can throttle power output MUCH quicker than that. So, it is possible to design a nuke plant that can adjust power output up and down quickly.

          Mind you, that doesn't really matter to the nuclear-phobic among us. So settle for having power sometimes....

          • by sfcat ( 872532 )
            Also liquid fueled reactors can be setup to naturally load follow without the need of additional equipment. But any power source that you scale up and down quickly will pay for it in efficiency. Its just that with nuclear you have so much extra power you can do that without taking a hit to your bottom line. Its also why marginal power is always more expensive than base load.
          • Naval reactors are fundamentally different in design than civilian reactors. Also worth noting is that the largest naval reactor is about half the size (in terms of thermal output) as the smallest civilian power reactor. You might as well be comparing the acceleration and braking performance of a superbike with a 200-car freight train.

            Being fully submerged in cold water probably helps too.

          You can run your nuclear plant at full capacity. And then use the excess power to recharge pumped hydro or batteries. You can sell the excess power to various industries that can throttle demand up and down easily. Like producing hydrogen.

          The economic problem of fixed capital costs vs practically free fuel is shared by solar and wind generation. Tell the people with the wind farms that we can't buy your power today and they will have an absolute fit. Not to mention running to the media with stories about '

      Nuclear power is simply too expensive when all relevant costs are considered.

    ...and pursue nuclear energy. There are reasons why all of the worlds top climate scientists support nuclear energy. Nuclear energy averages 12 g CO2 per kWh. Attempting to power our entire world with only intermittent renewables is not a viable option.

    Look at Germany. They have spent 500 billion on renewables and failed to decabonze their grid. They average more than 350 g CO2 per kWh after spending that much money. They have the highest energy costs in Europe. France on the other hand is much cleaner with their nuclear baseload, and their electricity is much cheaper

    We should pursue the options guaranteed to be successful such as nuclear. Given German failures pursing renewables we can not guarantee renewables will be successful.

      The price of renewables have been falling dramatically and will continue to do so.

        Those are costs of capacity. That's how they fool you. What you care about is how much of that power reaches customers. Even with renewables getting first in line (which is unique in the history of the energy market) they only make about 10% of their capacity because they are either making less power than their max or no power at all most of the time. That's why even though there are headlines about how cheap renewable power is, the utility companies don't want them. They do like small (by grid scale)

      There is hardly scientific consensus about the need for nuclear, and in fact many scientists point out that due to the very high costs and slow development times it makes more sense to invest the money in renewable energy.

      By the way, CO2/Watt in Germany has fallen dramatically. It's actually more than halved since 1990.

      CO2/Watt is misleading though, because it doesn't account for energy saving. Not generating electricity doesn't show up in a per-Watt normalized figure, and Germany has been improving energy

      • 350 g CO2 per kWh is a failure. Get back to me when they get to 35 g CO2 per kWh like nuclear France.

        For the record intermittent sources have much greater costs than nuclear energy. German failures after spending 500 billion is proof of that. Energy costs in Germany are the highest in Europe.

        And yes there is a scientific consensus among the top climate scientists and the IPCC for nuclear energy. Just because your head is so far up your ass that you can't hear them is not my fault.

          Your argument would be more persuasive if the market agreed with you and was pouring money into nuclear. It's not though, renewables have already won that argument.

          Energy has to be affordable, and if Germany had decided to go all nuclear the cost would have been crippling. The path they picked leads to sustainable, net zero emissions at an affordable price. Better still it makes Germany a renewable energy powerhouse, with technology and know-how that can be exported to the rest of the world.

          • There are 50 nuclear startups developing factory built rectors with NuScale being on the forefront. So there is money being poured into nuclear. China, Russia, and South Korea are also building nuclear power plants around the world.

            Germany has the highest energy costs in Europe. Their electricity is not affordable.

    • Germany produces nearly 50% of its energy CO2 free. I consider that a win and not a loss.

      They have spent 500 billion on renewables

      • 350 g CO2/ kWh is a fail.

        Every antinuclear person who complains about costs cares. It matters that they failed. If the money was spent on nuclear energy they would be 100% clean today. You can build 50 nuclear power plans at a cost of 10 billion euros each. Mass production can reduce costs much more than that.

        The government fucking owns the power plants.

        Who cares? Seriously WHO CARES?

        that peanuts money above would not have been enough to replace 40% of our CO2 producing plants with Nukes, only an complete idiot does not grasp that. Probably 10% we could have done, perhaps 20%.

        50 nuclear power plants at 1 GW each would be enough to power 100% of German electricity. You clearly are dumb.

    No matter what we do, whether we can make nuclear engergy safe or not, we will have to change our way of life.
    If we don't do it in time, and limit our growth and human activities, we will be forced to do so involuntarily.

    It won't be pretty. It will be the least pretty for those that are the least to blame for the problem. Those consuming the most resources will be able to protect themselves longer, but it will be impossible for them too. By then it will be too late for everyone.
