Renewable energy windstorm

Those shiny things on the right are wind turbines!

Those shiny things on the right are wind turbines!

As I wandered around the Kingston, Ont., waterfront last weekend, I felt very peaceful looking across Lake Ontario. It seemed to me that the icy expanse held the best of old and new: an early 1800s Martello Tower in the foreground, wind turbines on Wolfe Island in the background. From my point of view, this is a community with a plan for the future.

A lot of people have raised concerns about disruptions created by wind turbines. Looking around online at some of the problems people are experiencing, particularly homeowners, I certainly sympathize with their situations.

I think it makes all kinds of sense to generate as much power as we can through wind and solar. They are clean sources of electricity, and we’ve barely begun to tap the sun’s capacity. But we do have to put them in the right location, and that’s not right next to someone’s home. When turbines need maintenance, they start making noise (particularly older models, I’m told). I’d heard about noise issues before, but I hadn’t thought about how turbines interact with the sun. If you have spinning blades between you and the sun, guess what? You’ll get a strobe effect of light-dark-light-dark, as shown here.

The new Ontario Green Energy Act calls for a 550 metre setback between wind turbines and homes. When I first heard about the setback, I thought that perhaps traditional energy was influencing our ability to make good use of renewable energy. But now I see that, to make good neighbours, turbines should be situated properly. Nobody wants an annoying neighbour.

How do you see renewable energy fitting in with your landscape?
