From an interesting article in Mother Earth News.

Global non-renewable energy resources in terawatt/hours:

• Coal: 6,000,000
• Natural Gas: 1,500,000
• Uranium 235: 1,500,000
• Oil: 1,000,000
• Tar Sands: 800,000
• Total: 10,800,000

Global annual renewable energy sources in terawatt/hours:

• Direct Solar Radiation: 350,000,000
• Wind: 200,000
• Ocean/Thermal: 100,000
• Biofuels: 50,000
• Geothermal: 10,000
• Tidal/Wave: 5,000

According to the article, total world energy consumption in 2004 was 130,971 terawatt hours, and is projected to grow to 205,686 terawatt hours by 2030.

The article also says:

• "The total amount of energy produced by burning all the coal on the planet would only be equivalent to the solar energy that strikes the Earth every six days."

• "The entire recoverable world oil reserve is equivalent to the solar energy that strikes the Earth in one day."

• "The recoverable world reserve of fissionable uranium is equivalent to less than 1 1/2 days of the energy striking the Earth from the nuclear reaction of the sun."

I haven't been able to verify any of the author's numbers, but if they are even close it boggles the mind. You should read the whole article, and ask why we aren't seriously pursuing a distributed solar economy.
