I'm reminded of the scene in Mars attacks where the Martians suck up the hydrogen bomb lobbed at them and then inhale it like helium. (fusion joke)
edit:
The next thing I did was look at r/futurology and this was the top story:
bloomberg.comExxon Quietly Researching Hundreds of Green Projects
Two examples are new to me and interesting:
Quote:
- Carbonate fuel cells: Most fuel cells generate electricity by reacting chemically with natural gas or hydrogen. These ones use carbon dioxide. Exxon and FuelCell Energy Inc. are researching how the devices can be used in carbon capture and storage and to generate electricity at the same time. It’s building a pilot plant within a few months and is working on the engineering of the facility now.
- Process intensification: Exxon is working with Georgia Institute of Technology to develop a more efficient way of refining crude oil into plastic. It involves using a membrane and osmosis rather than heat. Exxon is targeting carbon dioxide emission reductions by as much as half with the process.

I'll have to watch Martian Attack. Didn't know Jack was in it.

No mention of Jack Black at Wikipedia? Or Slim Whitman? 20 yeas old but worth your time.

Keep in mind three things: This is installed capacity. Not output. So the solar amount of the green area will average 1/5 and have a 5X peak at noon to what is shown . And the wind portion of the green will average 40% with random intermittentcy. Batteries are way too expensive and lack the availability to do anything to buffer this at a grid scale of this magnitude.
.
And this is only electricity. Total energy use is 5 times this for agriculture, industrial, transportation, heat ect. much of which has no easy conversion from liquid fuel to electric.
.
Despite our awareness of the consequences, fossil fuel use will still be many times our current rate for decades to come until we are forced to quit when availability gets scarce.

Most installed wind doesn't generate even 40% on average.
Your typical install is a around 25% of name plate.
Where I am and west Texas they get around 50% of name plate.

Alta Wind was 2-3 Billion on 6,000 acres and is averaging 19% (Wiki states 30% but then also states annual production of 2,680.6 GWh) for .3GW.
.
$7-10/ Watt of average output installed.
.
So why do we cry and pull the plug on a new AP1000 reactor when it hits $7 instead of $4? And will crank out 90% of nameplate day or night for 60 years?
.
Comercial solar PV in my area is $2.50/ nameplate capacity Watt installed but only does 15%. So on average that would make it $16/ Watt. And there will be many days of zero in the winter.

Just mandate that social media be used on human-powered treadmills.
