Iowa is in the spotlight today, so it's time for pictures of barns.
But to save you waiting up, one important result is already in. Iowa generates a higher proportion of its electricity from wind than any other state in America ... 28.5%.
And, according to this report, this is set to rise to 40% by 2020. The industry also "employs around 7,000 people, has 12 turbine manufacturers, [and] has attracted $10 billion in capital investment" in Iowa alone.
It would be very easy for Wales, which also has a population of 3.1m, to do the same. Probably easier, because average household energy consumption in the US is about 11,700 kWh/yr compared with something like 4,600 kWh/yr here.
We are a long way behind them; in 2013, only 6.45% of our electricity was generated from wind.
