Earlier quoted context omitted.
Since we're firmly in the ridiculous arguments camp already, it may as well be pointed out that all of that energy leaving the planet is a good thing. It's why the earth isn't a barren hellscape like venus, whose atmosphere captures energy much more efficiently. Most people would actually prefer that we capture just a bit less than we currently do.
So you are saying we will capture so much energy from the sun that the entire planet will become inhospitable. Do we then just keep burning fossil fuels until earth becomes inhospitable instead? Or do we kill ourselves and stop the need for energy use entirely? Remember that humans will forever have energy needs as we advance.
I am obviously not an expert but I looked at the magnitude of the energy itself vs the greenhouse effect and it's about 10-100x less potent than the greenhouse effect. But that means that even if we had 100% clean carbon-free energy, we can't continue increasing our energy utilization forever. And we still have a huge portion of the world that is below a first-world living standard and will eventually want automobiles and air conditioning and vacations using jet travel too.
IF we do not level off the energy consumption of the "first world" standard of living sometime within the next 50-100 years then we are on a course to cook ourselves to death even with 100% clean energy.
