Renewable electricity capacity in China topped 1.45 TW or 50%, of which solar and wind power account for 970 GW in total.

    Are they able to store and distribute this or is it total production estimates?

      At this level it’s not that much of a problem. As pointed out it’s capacity not production.

      China has built huge numbers of HVDC power lines to move electricity around the country. Presumably their hydro is somewhat flexible. All their new coal plants are variable that’s somewhat of the reason why they are continuing to build new ones because they need the fast stop start. It’s basically what the rest of the world use gas for, but China use dirty coal instead.

      People also look at renewables as if it is traditional power. It is absolutely not. Renewable power will be wasted at times and that’s okay, it’s actually most financially stable way of operating.

      First you reduce fossil fuels plants/hydro to absorb the energy. Then you turn off fossil fuel plants for some time. Then you turn off renewables for a while. This is where somewhere like california/UK/Southern Australia is. At this point you still have expensive electricity at parts of the day but also really cheap (sometimes negative) electricity for significant parts of the year. Only then does it make sense to install batteries.

      2024 is going to be huge for battery storage. Especially if the sodium ion batteries work as expected which they are expected to. But even with batteries not all energy will be stored.

      This is installed capacity, not total production AFAIK.

      Solar, for example, can only achieve about a 30% utilization, compared to about 50% for coal plants in China.

      This type of comment reads really chauvinist, especially when you’re defending Biden for increasing oil production in the other thread

        or perhaps nuanced and realistic. The US needs to reduce coal burning too, if that makes you feel better. Whether it’s China, US, or any other country, the point is “X% renewable” is a meaningless statistic. The meaningful statistic is amount of CO2 we’re pumping into the atmosphere, which keeps growing.

        As for US oil production, I don’t like it, but it’s a necessary short-term political evil. Unfortunately average Americans really care about gas prices, it is what it is. The alternative allows for a higher chance of Trump or whatever other republican president who would be even worse for the environment.

          nuanced and realistic is when you hold other gvmts to higher standards than your own. Got it.

          While I agree with the amount of CO2 being the meaningful statistic, I see China doing a lot more in that regard than the US.

          • Per Capita CO2: China is way lower
          • Produces and deploys renewables on an unprecedented scale
          • Public transport is taken serious

          When the US/West exported it’s treat production to China pointing the finger to the total CO2 output is just chauvinist

            nowhere did I do that, nice straw man.

              yeah you do, you dismiss the US/Biden increase in oil production as a necessary short-term evil, but dont do so for China. ie you hold other goverments to higher standards than your own

          Have you considered investing in mass transit? Of course not. Biden is bought and owned by big oil just like Trump.

      Which won’t happen…

      I spent high school at an international school. Honestly, the students from china and other asian countries were so far ahead of the rest of the school (and our school was ahead of Australia). I remember in maths, I was first introduced to simultaneous equations by another taiwanese student in my class who solved a question we had to answer… We didn’t even start learning that until ages later (not that year, but I think 1 or 2 years later).

      There’s a lot of low quality products coming out of china, but, their problem is they do a lot of things cheaply which allows crap to leave the country, but there seems to be a lot of really good engineers there too, and I seriously doubt they put crappy engineers into building the three gorges.
