April Fools Comes Late to the Sloop?
There's more about this at Curbed Chicago. It seems this was a hoax by a group with an agenda and they took aim at a company that owns a power plant that already operates in the city. A clean power ordinance was stalled recently in the Chicago City Council that would've forced this company to switch from coal to natural gas.
One way I suppose to at the very least bring attention to a subject. Although to be honest I know very little about whether or not coal or natural gas is much cleaner fuel.
