"A battle is brewing in Congress over a climate and energy issue that is pitting the U.S. Senate and states west of the Mississippi against the U.S. House and states east of the mighty river.
It's a fight over expansion of the electric grid – the building of a new 'transmission superhighway' – with boosters claiming you can't have a clean energy future without it, and more cautious skeptics saying it could be a huge waste of money that would hurt both the economy and the climate.
A scene from this unfolding political drama was performed before Rep. Ed Markey of Massachusetts last week, who held a hearing on the future of the grid in his House Subcommittee on Energy and Environment and set the stage with his opening comments."
