Fossil fuels (natural gas, coal, crude oil) are by far the greatest producer of energy for humanity today. What are the next six largest energy sources?

Actually, your fossil fuel group is 2nd on the list for "the greatest producer of energy for humanity today". No.1 is the Sun which bathes the Earth with about 175 billion megawatts EVERY SECOND ! In fact the Earth receives more energy from the Sun in just one hour than the world uses in a whole year. The list continues: 3rd Hydroelectric 4th Nuclear 5th Geo-thermal 6th Wind 7th Solar Dec 27 03, 4:48 PM

Good show, sequoianoir (I was afraid no one would answer my question)! You are correct, it is estimated that each year the Earth recieves ten times more energy from the sun than the entire Earth's supply of fossil fuel. However, in your list one energy source was missed - Biofuels (wood, landfill gases, agricultural waste) which would appear between Nuclear and Geo-thermal... Dec 27 03, 5:40 PM

I hadn't forgotten Bios, I'd got that in 8th place after all the others (based on 2001 figures) Dec 27 03, 5:54 PM

What is the difference between Light Crude Oil, and Brent Crude Oil. And where did Brent Crude Oil get it's name? Largest consumers of coal in India? I live in upstate New York. Hurricane Katrina hit the refineries down south a few days ago, and the gas prices have gone up 50 cents. How long does it actually take from the time the crude oil gets to the refinery until it gets to the pumps? Largest oil tanker ?
