The following submission statement was provided by /u/ForHidingSquirrels:

Offshore wind electricity generation could power the world with all of its energy needs. Offshore wind happens to be decently disbursed at higher latitudes in both the north and south hemispheres. Already we couple solar and food. If we’re ahead sending people out to manage the wind farms, might not be so hard to also send people to manage the food farms between the wind turbines?
