The only way to keep up with rising demand will be to use everything. Solar, wind, tidal, geothermal, nuclear, and every ounce of fossil fuel on the planet. I think before very long we'll come up with some kind of carbon reclaimation scheme, even if it's as low-tech as turning wastepaper and sustainably harvested pine into charcoal and burying it in tapped-out coal mines.
There will be trouble when we run out of petroleum, but hopefully we'll be able to compensate with fusion. And, of course, the "energy companies" as they've rebranded themselves will start rolling out all of the gasoline replacements they've had waiting in the wings for decades, like that bacterium they found in zebra poop that turns cellulose into butanol.
