By showing only your provided data it seems. But when looking at the share of primary energy consumption from renewable sources it looks totally different!
If you look at the growth rate of renewables it should be pretty clear that coal will not play a major role in the foreseeable future.
Why is it not saying 18% of the needs are being met by renewables? That's exactly what it does
This is not energy output (production, usage), it is that plus an adjustment for the in->out energy efficiency. It would only == production if all energy sources in the mix has the same factor.
Because fossil fuels have higher in/out losses this is number is larger than usage. This metric is generally used to track decarbonization.
Using the IEA number you can see the hydro+solar+wind production is about 9.5% of the total, not 18%.
ChatGPT or you favorite LLM can explain in greater detail, just send it the plot image and ask.
The adjusted graph is a better reflection of "meeting their needs" than raw primary energy, since more than half of fossil primary energy is lost as waste heat.
I am selfhosting a few applications at home and found managing redirects always a little cumbersome. There are lots of SaaS solutions out there, but no FOSS selfhosting ones.
