I assume you're being sarcastic, in which case maybe you don't understand how global warming works. The overall solar energy flux to the Earth is huge — around 170 exawatts — almost all of which gets re-radiated into space. CO2 and other greenhouse gases affect how well the earth can radiate waste heat. If we were to replace all human energy generation with off-planet beamed energy, this would increase the influx by something like 0.01%; that won't change the equilibrium point much (remember the S·B law is fourth power). In contrast, the CO2 generated by fossil fuel use changes the earth's emissivity, which does have noticeable effect on the equilibrium point.
