Humans use about 1/3 of all energy captured by photosynthesis on the earth.

This takes into account agriculture, lumber, fishing, etc.

I may be misremembering that number, but it was something like that. I read it in E O Wilson's Diversity of Life, which, IIRC was written in the 90s, so if anything it's probably higher now.
