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
Electric power generation, which is about 20% of all energy used.
What’s the difference here?
Not all gas, coal and oil are consumed to generate electricity. Lots is converted directly to energy in engines, furnaces, or other direct uses for the materials. They are saying that the title refers to 40% of the total electricity production is generated by renewables.
I’d love to know how much that percentage fluctuates with seasons, but on a global scale. Does summer in Australia compensate for winter in America, and vice versa, so that the sum is still 40% throughout the year?
Definitely not. There’s much less land mass in the southern hemisphere, so there’s also less utilisation of natural energy. Speaking as an Australian we’re also not super great at embracing the whole renewables thing so that definitely comes into it too lol.

Erm… Australia has the highest (per capita) number of rooftop solar installations in the world and one of our states (south Australia) is already 99.8% renewable when the weather is favourable (and they are still rapidly deploying more - expecting to get to 100% even in shitty weather long before almost any other country in the world).
Ww emit the same level of CO2 as the USA. And we’re increasing that every year
Nuklear fanbois hate this one simple trick
FFS… They could at least fucking skim the report they are writing about. It’s not 40%, it’s 28%…
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. According to the International Energy Agency (IEA) (2023), demand is expected to grow by slightly less than 2% in 2023.
That’s very good 😊

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

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

So, did they mix up 14 with 40?
JohnDClay@sh.itjust.works 1 year ago
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.
