Going with the earlier article in the NYT about US infrastructure: The cost of alternative energy production is coming down, but the cost of transmission isn't.

High transmission price could seriously hamper alternative energy efforts which often require the transportation of large amounts of energy over long distances.

Gym in Portland, OR hooks up its equipment to generators in hopes of generating 100% of the energy it uses.

I wonder if there will ever be a time when energy prices are high enough and generators on exercise equipment efficient enough that gyms can replace membership fees with the money they make from energy generation.
