Global warming legislation dying in Iowa

From this article:

So, with only a few weeks left in the session, what have legislators done to promote smart energy use? Not nearly enough.
There was no serious attempt to adopt greenhouse-gas reduction targets as state law. Eighteen states have set targets, including neighbors Illinois and Minnesota, according to the Pew Center on Global Climate Change.
Culver’s “25 percent by 2025” target for renewable energy died in March. Twenty-eight states have adopted renewable-energy standards, many of them more aggressive than Iowa’s, Pew Center data show.
And the recommendations to ramp up utilities’ energy-efficiency efforts ran into a buzz saw of opposition from all involved.
