Halifax is looking at wind energy as a greener way to lower its power bills.

The municipality has asked companies to submit proposals for the supply of alternative energies.

"We prefer to be green," Julian Boyle, the Halifax Regional Municipality's energy auditor, told CBC News on Wednesday.

"But we think there's a very strong likelihood that also there will be some positive financial impact to signing these kinds of contracts.

"We're just like any other customer, we're not looking to pay more for power than necessary."

The cost of fossil fuel and coal-based electricity is going to escalate, Boyle said, so it's important to look at alternatives.

The municipality is particularly interested in wind energy, and staff recently created a plan to show where turbines are best suited. A turbine in an area with strong winds will generate more energy than one in a less windy place.

Boyle said those sites need to be accessible to Nova Scotia Power's transmission system yet far from "no-go" areas, such as urban centres.

Though many details have yet to be worked out, Boyle said there's no reason why Halifax couldn't procure 100 per cent of its power through green means one day.

He said municipal officials are sorting through the proposals and expect to present a report to regional council in November.
