Yes. Sunlight that makes it to the surface is about 170PW. Primary energy is about 17TW this is roughly on the order of what can be utilized without drastically altering the planet. GHG emissions shift the balance by about 200TW which is enough to be extremely harmful. 20kW is 170TW which is enough to be similarly harmful (although not to escalate to being apocalyptic). 2000MW per person is enough to raise the temperature of the entire earth (the whole thing, not the surface) by 25 degrees a year.
