Current rates of solar-wind-battery *already* on-track to carbon neutral by 2040-ish

I keep hearing that it’s *impossible* to go carbon neutral.

That’s odd, because at current production and adoption rates of the solar-wind-battery and EV paradigms we’ll get there by 2040-ish.

Electrification is on target

The rollout trend of photovoltaics for both rooftop and farms, and wind farms, both on land and sea, are sufficient to get us there!

Annual rollout rates, assuming no growth, of these technologies gets us there by around 2060.

But the rate of growth is so high right now, we’re only a doubling away from getting there by 2042-ish. Solar is growing by around 45%, and not from a trivial base any longer, of 1.5 TW out of the required 18 TW.

It’s a similar story for wind and EVs.

It means that, far from not making it by, say, 2050-ish, we’ll get there sooner.

This has all been mapped out by companies like Tesla and ReThinkX. See the link at the post footer to check it out yourself.

The disbelief comes from ignorance about what’s transpired over the last decade. And about the reliability of certain types of modelling.
