We simply don't have the capability to do it.
energy output by sun reaching the earth's surface or what?
anyway regardless, surely some of the rest of your comment is in support of anthropogenic GW, no climate scientists are claiming we can produce enough energy to warm the earth, that would be daft. What they are claiming is that instead of the small percentage rise in solar energy production you mention, they are claiming a small but significant percentage rise in the amount of solar energy which doesn't get re-emitted by the earth.
The quantity of energy that humans create is neither here nor there, the argument is about
:
whether greenhouse gases exist (pretty much proven),
how much impact various greenhouse gases have,
whether mankind is capable of having a significant impact on the quantities of greenhouse gases in particular CO2
Then if you accept the scientific information above you enter the quagmire that is how the earth's climate will react to the increased greenhouse gas and heat. Will it overall be negative feedback to maintain current temps, positive feedback which will screw us, or will it be neither (also will probably screw us)
