    Our heat generation is just a 'blip' compared to the total solar energy input:

    http://en.wikipedia.org/...

    Solar    3,850,000 EJ
    Wind    2,250 EJ
    Biomass potential    100–300 EJ
    Primary energy use (2009)    510 EJ
    Electricity (2009)    62.5 EJ
    The extra solar energy retained due to increased CO2 levels far outweighs the extra heat we produce, at least on a global scale.

    Locally, energy use can affect temperatures, the 'urban island' effect, but that really only matters when trying to construct a uniform consistent temperature record.
