The presence of prairie winds and rich soil makes Iowa literally fertile ground for developing alternative energy sources from wind turbines and biofuels.
But the landscape is also a reminder that achieving energy independence is a formidable challenge and making an agricultural economy green is not easy.
Farm workers cannot take subways to work, farmers have to drive long distances into the fields to sow and harvest their crops and to deliver them to markets.
Farm animals themselves, not to put too fine a point on it, produce methane - a powerful greenhouse gas - that is trapped in the atmosphere.
Those challenges have not stopped the state setting itself ambitious goals.
