Zach Galifianakis Math meme

By "solar power in operation" (in GW) i think they mean maximum output capacity rather than actual production, since these numbers add up to 923 GW while wikipedia says in 2024 there was 2.13 petawatt-hours (243 GW on average) actually produced by solar.

wikipedia screenshot with pie chart. 2024 world electricity generation by source. Total generation was 30.85 petawatt-hours. Coal 10,587 (34.4%), Natural gas 6,796 (22.1%), Hydro 4,417 (14.4%), Nuclear 2,765 (8.99%), Wind 2,497 (8.12%), Solar 2,130 (6.92%),Other 1,569 (5.10%)

US once again beaten by rest of world.

China putting china on top of the charts is expected, but it's per capita production that makes more sense for direct comparison of countries.

In that case.. Australia is the leader by a strong margin..

Per capita production makes no sense actually, per capita consumption makes sense, and that's double of that in China in Australia.

[–] [email protected] 1 points 4 hours ago* (last edited 4 hours ago) (1 children)

Doesn't that table show Australia has double the consumption? also that consumption number is in total primary energy, regardless if the energy comes from solar or not.

I believe that to see how much of the TPES for each country comes from solar we would need to divide the solar production per capita by the total consumption per capita:

- Australia: 1774 kWh / 63257 kWh = 2.80%
- China:      410 kWh / 33267 kWh = 1.23%

When it comes to China, you really have to look at latest numbers because how much renewable installations there change year to year. China hit an inflection point in 2023 where fossil fuel usage started to shrink:

China installed more solar in 2023 than the rest of the world combined, with the majority of it coming online in the country’s sparsely populated west and north.

That same year, its renewable capacity grew faster than its overall demand for electricity — meaning its fossil fuel usage actually went backwards.

https://www.abc.net.au/news/2024-12-18/survey-of-the-worlds-solar-shows-global-boom/104006096

Then, in 2024 China continued to massively expand renewable usage (including solar)

China has achieved another year of remarkable growth in renewable energy, with the addition of 277 GW of solar and 79 GW of wind capacity in 2024. This surge has brought the cumulative solar and wind capacity to a staggering 1,407 GW. China contributed 15% of the world's installed solar capacity in 2024 alone.

China hit new record of solar and wind power capacity additions in 2024 https://climateenergyfinance.org/wp-content/uploads/2025/02/MONTHLY-CHINA-ENERGY-UPDATE-Feb-2025.pdf

China was at nearly 50% of the world’s solar capacity in 2024 according to IEA https://reglobal.org/snapshot-of-global-pv-markets-2024/

China’s new PV installations forecast to reach up to 255GW in 2025 https://www.pv-tech.org/chinas-new-pv-installations-forecast-to-reach-up-to-255gw-in-2025/

The pace of transition to renewables in China is on a completely different scale from the rest of the world.

Were looking to supply Asia with power soon. Afaik this is all Northern territory, not eastern seaboard.

I'm just impressed the UK can even be in the top 10.

[–] [email protected] 3 points 13 hours ago (1 children)

I reckon we’d be doing even better if it was total renewables, we lean toward wind power more than most, what with being an island and all

[–] [email protected] 2 points 8 hours ago (1 children)

That would put you in competition with places like canada, that are 76% renewables though, if you count hydro.

For wind alone (according to wikipedia) you do do better, but are still in 6th place.

[–] [email protected] 1 points 4 hours ago

You'd also have to count all the oil and gas that Canada exports to be burned around the world. Whether it's used domestically or not doesn't really make a difference.

[–] [email protected] 4 points 14 hours ago (2 children)

Data should be per capita or another relative measure.

[–] [email protected] 3 points 13 hours ago* (last edited 13 hours ago) (2 children)

If you want it Per Capita, try this one with data from 2023.

Pretty different story naturally.

(edited link to include the same countries as the op post)

[–] [email protected] 2 points 6 hours ago

But still, China is going full power on renewables, eventually they will pull ahead there as well, unless west or others start investing in renewables seriously.

[–] [email protected] 1 points 6 hours ago

Indeed that paints a different picture as suggested.

[–] [email protected] 1 points 14 hours ago

Yes, solar per capita, or percentage of solar in total energy production.
