About 40% of the world’s power generation is now renewable::About 40% of the world’s power generation is now renewable

		83% of new power capacity created in 2022 was renewable, according to a report from the International Renewable Energy Agency (IRENA) and World Meteorological Organization (WMO). The report takes stock of the world's renewable en

    I don’t see a graph here or source, do you know where it’s from? This is giving about 25%.

    World energy data

    From 2022

    Edit: here’s the original paper if people want to dig through it for the data. I have a feeling the headline above is just the capacity rather than the actual generation.

      The source in the article claims 27.8% so who knows…

      Actual power generation depends on the capacity factors (CF) – namely the ratio between the average electricity generated by a power system and its nominal rated (or maximum) power. Thus, in terms of power produced, in 2021 (the latest figures available) hydropower generated 4 400 TWh, wind power 1 840 TWh, and solar power 1 030 TWh (IRENA, 2023b). The total global electricity consumption, from all sources, including renewables, was 28 500 TWh in 2022, a 2.5% increase compared with 2021 (and a 25% increase compared with ten years earlier, 2013) (EMBER, 2023). According to IRENA (2023b) the percentage of electricity consumption met by RE was 27.8% in 2022, up from 27.6% in 2021.

      But in general they are talking about electricity, not energy. Maybe the 40% comes from best of situations when it’s windy where it needs to be and sunny where it needs to be.

        Idk. They might be playing tricks with installed capacity vs the actual energy coming from them, since solar and wind only produce at peak capacity sometimes.

      Biomass is also pretty much the worst “renewable” energy source. Consume a buch of water, use land that could be used for food, rising the cost of basics from the people that can’t afford to pay more.

        And I wonder what the efficiency is compared to something like solar, growing a tree for years just to burn it. I’m guessing it’s pretty abysmal.

        Efficiency-wise, solar takes the lead. It converts around 15-20% of the sun’s energy into electricity, thanks to advances in tech. Biomass lags behind with 2-3% efficiency, mostly because of heat loss when burning.
