Hydrocarbon energy, or any other sort of energy source used by society has no mandated production under capitalism. It does not involve an actual command to produce anything, in contrast to communism which does. Here is a good definition of capitalism:
"Capitalism is an economic system characterised by private or corporate ownership of capital goods, by investments that are determined by private decision, and by prices, production, and the distribution of goods that are determined mainly by competition in a free market. Modern Capitalism is essentially mass production for the needs of the masses."
If hydrocarbon energy is the source of power production, then this simply reflects what consumers want. If wind power was what consumers wanted, then it would be the dominant source. Capitalism does not care what is produced, all it cares about is that prices and barriers to competition are left alone from intervention.
Suggesting capitalism asserts endless growth is a strange comment. I'd wager you don't understand what growth actually means.
