Cover the corn fields that are 95% being used to produce ethanol for fuel mixture into gasoline. Replace a one-time-use fuel that takes a ton of water to produce, contributes to pesticide usage, and requires a bunch more energy for processing (and makes your car run less efficiently anyway) with energy that can power homes, vehicles, industry, etc. starting now and lasting for decades with a one time investment into fully recyclable materials that is already pretty low cost and lowering all the time.
