Imagining worlds without oil sounds like the easy work of daydreams. But the future is a complicated place, even when we're making it up. Even the most outrageous fantasies – from inter-galactic, cross-species space flights to time travel – must also be plausible. This is something every movie maker knows, or learns the hard way -- from fans. Popular series have always inspired "fan fiction," in which story buffs spin new tales about their favorite characters. Today, there are Internet forums and unofficial web shrines where fans discuss the finer points of sci fi. The worlds fans love may not exist, but they are experts in them anyway. They know what powers a lightsaber, where the USS Enterprise gets its fuel, or how The Matrix “really” works. Even fantasy worlds have rules, and the best fans know them. Do you?

Every energy source is a Faustian bargain. We trade comfort and convenience for deforestation, soot, radioactive waste, oil spills. But perhaps the most unsettling resource we tapped to light our homes was the one that the petroleum age displaced: the slaughter of whales for their oil.
A new energy revolution – similar to shifts from wood to coal to oil – is inevitable as climate change and oil scarcity drive a global search for sustainability in power production. But even the promise of renewable energy holds drawbacks.
