The radius of the earth is about 4000 miles. We are about 93 million miles away from the sun. So the earth covers pi*(4000)^2 square miles of the sphere of area 4*pi*(93,000,000)^2 square miles. This gives a fraction of 4.6810^(-10), or about one 21 millionths of a percent.

Picture how many Earths it would take to make a sphere that would catch all the energy of the Sun. Mind boggling

Apparently, the sun emits 2 billion times as much radiation than what reaches the earth. So from that, the answer would be 0.0000000005%.

It's not up to 1%. but then the earth tends to make it hotter again.
