That's incorrect. It's in the order of 25% of the heat reaching the Earth's surface, or maybe 35-40 watts of heat per square metre. That's roughly ten times the warming effect of doubling CO2. Now, I don't have a climate model handy to simulate this in detail but I would suggest "render the Earth uninhabitable" is a close enough approximation to the actual effects to suggest it's a terrible idea and anyone seriously proposing it should be laughed out of the room until they've done their homework. | ||

Total energy use by mankind is about 200,000 TWh a year https://ourworldindata.org/energy-production-consumption Most of that is lost in waste heat. Total energy arriving on earth from the sun is about 1,500,000,000 TWh https://smartstep.blog/how-much-solar-energy-hits-earth-per-... 7500 times higher | ||
