Yes, it's negligible. Before considering atmospheric attenuation, every day something like 15,000,000,000,000,000,000,000 Watts (15 Zettawatts) of the sun's power reaches the earth. SOURCE
So enough power hits the earth in a second to power the human population's activities for many months at a time.
You would think that's enough to put into perspective how bad energy trapping atmospheric emissions are, but nope.
