The world is improving
In the year 2000, the share of green energy (including renewables and nuclear) in global electricity generation was significantly lower than today.
Renewable energy (excluding hydro): About 2% of global electricity. Wind and solar were in their infancy.
Hydropower: Around 17%, making it the dominant renewable source.
Nuclear power: About 17% of global electricity.
Total "Green" Energy Share in 2000:
~36% (Hydropower + Nuclear + Early Renewables)
Since then, nuclear's share has declined slightly, while solar and wind have surged, pushing the total green energy share toward 50% by 2030.
