This question will resolve as YES if renewable energy sources, such as solar, wind, hydropower, and geothermal, collectively surpass fossil fuels, including coal, oil, and gas, as the primary source of energy worldwide by the end of 2050. The determination of primary source will be based on the total global energy consumption from each source.
The question will resolve as NO if fossil fuels remain the primary source.
Very true. I'll allow that synthetic fuels that are generated from solar power through processes such as carbon capture from the atmosphere and turning it into natural gas will be counted as renewable energy sources for the purpose of this question. The determination of primary source will be based on the total global energy consumption from each source, including synthetic fuels.
@kian_spire Thanks for the clarification! We'll have to make sure the synthetic fuels don't get double-counted in fuel consumption as well as solar for fairness, but that's a practical problem for the future :)
