If you look at global power sector emissions from 1998 to 2018, you'll see that while we have dramatically improved upon the energy intensity (energy/capita) and even are making improvements on carbon intensity (carbon/capita), but the sad reality is this: we are still using around 35% coal power in 2018, the same as we did in 1998.

And the power sector is the easiest sector to decarbonize, by the way. If you look at electric vehicles, even if we had the most rapid, insane ramp-up that's beyond even Elon's crazy predictions, we'd still have massive fossil fuel use for non vehicle uses of petroleum for chemical industries, airplanes, plastic production, and for the numerous numbers of legacy cars that will be leftover that are not EV.

We need massive innovation across all our uses of fossil fuel. We can not rest on our laurels, saying PV and wind are so cheap now. They are still around 4% of total energy consumption, and when you factor in the decline of nuclear and relative decline of hydropower in the ever-increasing industrial energy base, we see that fossil fuels are basically the same % of our energy mix as they were before 2000.

For an energy realist, I recommend checking out Vaclav Smil, who has long been predicting 21st century as the century of natural gas, and who has been skeptical of renewables taking over instantly. It will take us until the 22nd century to truly decarbonize, and by then the seas will have risen over Miami and Shanghai on a regular basis.

It's a truly scary future. Get innovating, in your personal lives and in your professional careers, everyone!
