At the moment not really, yes.
But he was speaking of the possible scenario with unlimited avaiable energy and therefore much more energy spending ... but I also don't see this as a real concern. Global Human energy output would have to increase by many numbers to make a significant impact.
Someone up thread posted the figures, human energy is 12 terawatts, the earth receives 172,000 terawatts a day, replacing all of energy usage with fusion and then doubling it to 24 terawatts would likely result in a cooler planet (since we'd be producing far less carbon dioxide).
