How much of the suns energy does the earth reflect

Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system. Of the 340 watts per square meter of solar energy that falls on the Earth, 29% is reflected back into space, primarily by clouds, but also by other bright surfaces and the atmosphere itself.

could you go a bit more in depth with you question? it's quite hard to understand. as soon as you do that i will be glad to : )
