When evaluating fossil fuels shouldn't we also consider the direct heating effect of using the fuel? [View all]

So for example when a car is operating there is tremendous waste heat being generated along with CO2. This heat is given off into the air around the car and adds to the overall heat level of area. Its really noticeable when you park your car in your garage and shut the garage door. It's get incredibly hot. So considering there are over a billion cars on this planet, this effect would seem to be significant.

Then of course all the other uses of fossil fuels.. heating homes, generating electricity, powering all sorts of engines and equipment, etc. This all adds to the direct heating of the environment.

Is this level of heating insignificant in comparison to the effect of CO2?? I don't know for sure but I would think it would have a significant additive effect, a bit like operating a wood stove in a greenhouse.

We can also think of this like injecting heat into the environment that was captured from the sun eons ago. This energy has been stored in fossil fuels and we are now releasing it. It's like we are increasing the current sun's output.

I don't know what specifically can be done but seems its something that needs to be seriously considered.

That's a good point... Think. Again. Jul 2023 #1

Yes. Good idea! calimary Jul 2023 #3
SHOULD be PART of the evaluation. elleng Jul 2023 #4
Should not be. It's miniscule, lost in the noise. 8320 global warming vs 44.4 heat Bernardo de La Paz Jul 2023 #20

Parking lots do not combust fossil fuels. They do collect energy, so they should all be white. . nt Bernardo de La Paz Jul 2023 #7
Better yet... Think. Again. Jul 2023 #23
Yes. You made me think again. . . nt Bernardo de La Paz Jul 2023 #24
Some interesting information in the introduction. honest.abe Jul 2023 #13
No need. The level of heating is insignificant compared to CO2, because CO2 operates for decades Bernardo de La Paz Jul 2023 #6
Yeah but direct heat doesn't go away either. honest.abe Jul 2023 #9
Sure. But you are comparing a one-time energy release to decades of heating by trapping solar Bernardo de La Paz Jul 2023 #21
Insignificant compared with the suns heat Blues Heron Jul 2023 #8
Yes, that's the question I was asking. honest.abe Jul 2023 #10
think how hot your garage got from that engine vs how hot the sahara desert gets Blues Heron Jul 2023 #11
I was looking for a more quantitative answer. honest.abe Jul 2023 #12
OK - world energy demand is about 624 exajoules/year, the sun gives us 3,850,000 exajoules/year Blues Heron Jul 2023 #14
Would you mind providing a link to support your numbers? honest.abe Jul 2023 #15
no prob Blues Heron Jul 2023 #16
Thank you. honest.abe Jul 2023 #17
directly caused by our added CO2 above pre industrial levels? or total CO2 Blues Heron Jul 2023 #18
Numbers do exist. See my post #20. . . . nt Bernardo de La Paz Jul 2023 #22
there are numbers for that - the total energy demand per year vs the radiative forcing of CO2 Blues Heron Jul 2023 #25
Thanks. I will take a look later. honest.abe Jul 2023 #26
radiative forcing of 1.8 W/M due to our added CO2 is like space heaters 72 feet apart Blues Heron Jul 2023 #27
That's intense! honest.abe Jul 2023 #29
