Last week the Village of Oak Park Board of Trustees voted to accepted a bid from Constellation Energy, to supply the aggregated electricity for the Village. Constellation will use fossil fuels, or brown energy, to produce the electricity. The current supplier, Integrys, generates energy from wind power, a renewable and green resource. The bid for the new contract from Constellation is $4 per month cheaper than that offered by Integrys, for the averge user. This decision will mean that about 20,000 homes and 2,000 businesses in the Village will be using brown energy, unless they opt out of the contract. 95% of the homes and businesses in Oak Park participate in the current contract for green energy with Integrys.
