Well, it doesn't need to equal the irradiance of the sun to be a big effect. 1% of the sun is still a hell of a lot of extra warming.
At an annual growth rate of 2%, that 12 TW becomes 1% of the sun in 250 years. Not all that long when solutions are 50+ years out. If you're a fan of keeping capitalism going, we're going to need faster growth than that.

It would also require us to become a level I Kardashev Scale civilization (harnessing all the energy reaching our planet from our star, or the equivalent). But it does set an upper limit on how much can be done on a planet.
