Renewables seem to be growing quite fast, the fear I have is that electrification may take longer. Car transport seems to be 'solved' (just needs roll-out over decades). But many other industries may take more time.

Electricity is just 20% of energy use. [0] And forecasts for 2040 are set around 28%. Even if electric goes all-renewable, you're still not there if you use non-electric for heating, industrial, air, sea etc.

Second, renewable growth is quite strong now yet there's large increases in energy use and decreases of nuclear. All in all, it appears the share of no/low-carbon energy sources in 1995 (i.e. renewables incl nuclear and hydro) was roughly large as it is today [1], but unfortunately on a much larger total energy consumption. [1] That's absolutely depressing. It seems the trend has finally set in the last few years, but we're a long way from home.

If we're talking 1950, I'd be an optimist. But it seems we're very much on a tipping point. The fact we'll be able to innovate ourselves to low-carbon is something I'm very optimistic about, but in the necessary timeframe... I'm very concerned.
