Did you know (from wikipedia and wikipedia here as well):

• In 2009, world energy consumption decreased for the first time in 30 years (-1.1%) or 130Mtoe, as a result of the financial and economic crisis.
• In 2008, total worldwide energy consumption was 474×10¹⁸ J (474 exajoules) with 80 to 90 percent derived from the combustion of fossil fuels, equivalent to an average power consumption rate of 15 terawatts (1.504×10¹³ W), .
• 1.5×10²²J, the total energy from the Sun that strikes the face of the Earth each day
• 3.9×10²² J, the estimated energy contained in the world’s fossil fuel reserves as of 2003

So basically two days’ worth of sun power (if you could capture all of it which you couldn’t) is equal to all the fossil fuel reserves we have left. Fun with numbers!
