Coordinated through it's Office of Energy Independence, Iowa is also investing more heavily in energy efficiency and other forms of renewable energy such as advanced biofuels, biomass and biogas methane capture (plenty of hogs).
Having personal ties to the Hawkeye State through my dad's family lineage, I am quite proud to share in this great accomplishment driven by the citizens and business and government leaders of the State. I bet if you interview a few Iowans they'll know nothing about a 'clean energy challenge' because thus far it's been all opportunity - economic and environmental alike - afforded to them through home grown renewable energy development. I am confident that these winds of clean energy change will sweep into other states throughout the Midwest region and our nation as a whole.
