Don't we already kinda do this with Ethanol, and aside from how growing so much corn is also bad for the environment, how it's a less efficient fuel, and other concerns (indirect land use change etc), it already works to des crease our dependence on the stuff in the ground? https://en.m.wikipedia.org/wiki/Ethanol_fuel_in_the_United_S... |

The inputs to this are just energy + water + CO2 = oil. No corn or other plants required. Currently this type of technology is far from cost competitive. But that could potentially change if more was invested into this area.
