That depends on how you define "sustainable". So far, a perhaps pessimistic assessment of sustainable energy is that it's driving up energy costs, while reducing the increase of CO2 emissions by only a very small amount. It's increasing fuel poverty and deaths from cold weather events, and ultimately it will drive business out of the countries that are building sustainable energy into countries that have cheap energy, by making business uncompetitive. Then, people will buy products from the cheap energy countries that are emitting CO2 (although they'll be poorer, so perhaps they'll buy less).
