On the other hand, at a fixed doubling period of 35 years (i.e. assuming 2% yearly growth) we'll get at that "one extra sun" level in only 500 years.

Or if we take "5% of an extra sun" as the problematic power output, it will take only 150 years.

(Now consider that in the golden age of oil before the oil shocks in the seventies, oil consumption was growing more like 8% per year.)

At that time, per capita energy use in the US was growing by 3% per year while population would grow by 1.5% per year. Today, per capita energy consumption in the United States is falling, and the population is growing more slowly. The story is much the same elsewhere. Even China has leveled off in per capita energy consumption. India's is still growing, but it will take many years considering their baseline of 1/10 of the United States per capita before they're the biggest problem, and I guess they'll probably turn that trend around before they actually get to that point.

In that scenario, we are doomed anyway: If we would generate anywhere close to that level of power via solar, we would change the albedo of earth significantly -> heating. And we would certainly affect the air currents on a global scale if we use wind power to that extend.
