The Impossibility Of Bridging The "Last 10%" On The Way To "100% Clean Electricity"
/As my last post reported, the Official Party Line from our government holds that we have this “100% Clean Electricity” thing about 90% solved. As the government-funded NREL put it in their August 30, 2022 press release, “[a] growing body of research has demonstrated that cost-effective high-renewable power systems are possible.”
But then they admit that that statement does not cover what they call the "last 10% challenge” — providing for the worst seasonal droughts of sun and wind, that result in periods when there is no renewable power to meet around 10% of annual electricity demand.
That last 10%, says NREL, will require one or more “technologies that have not yet been deployed at scale.”
But hey, we’ve got 90% of this renewable transition thing solved. How hard could figuring out that last 10% really be?
