For years, renewable energy has been touted as the source that would be replacing fossil fuels very soon. Yet renewable energy sources accounted for just 12.5% of the global primary energy consumption in 2020. Surely, there has been a steep rise in the share of renewables in the global energy mix in the last few decades. Fossil fuels still fulfill more than 80% of the world’s energy needs.
That means while a transition to renewables looks inevitable, it would be far slower than expected, spanning over several decades.
