Solar power on pace to save the world

A think tank analysis suggests that if solar power keeps up its growth pace, along with wind, then the global power sector will meet its carbon reduction targets to keep world temperatures in check.

According to Ember, an independent think tank, if wind and solar keep up a 20% compounding growth rate over the next 10 years, the global power sector has a chance of meeting the decarbonization goals that are needed to keep the world’s temperature increase at or below 1.5 C.

If solar electricity generation keeps up the year over year growth rates of the last ten years – 33% – for another 10 years, then solar will without a doubt be pulling its weight in mitigating CO2 emissions. The report suggests that solar “only” needs to grow at 24% over the next decade to meet its goals.

The analysis found that solar electricity generation rose by greater than 23% last year, and that wind grew by 14%. The two sources officially surpassed 10% of global electricity generation last year, and when combined with other clean electricity sources (nuclear and hydro being the other two largest), they hit 38%. Combined, this means they passed the world’s largest electricity generation source – coal – at 36%.

Globally, 50 countries now meet 10% or more of their electricity demand with wind and solar. Three countries dramatically surpassed that target: Denmark, Luxembourg, and Uruguay produced 52%, 42%, and 47% of their respective electricity supply using only wind and solar power. The current global leaders in solar power are Yemen, at ~15%, Chile at 13%, and Australia at 12%.

But the news isn’t all roses. Coal consumption ramped up last year as a result of China’s continued growth, as well as the recovery of the global economy and related electricity demands. In absolute terms, the global electricity demand increases of 2021 were the largest ever observed. Unfortunately, growth in wind and solar — also the largest ever observed — supplied only 29% of that increased demand for electricity.
