If you live in one of the many areas that have implemented smoking bans over the past few years, you’ve likely been able to appreciate cleaner air inside of many bars and restaurants, while smokers stay outside. But did you realize that in colder climates, smokers are provided with a heat source for their smoking area which is often electric heat? In some places, like Scandinavia, some restaurant owners even go as far as to internally heat the pavement of their sidewalks to make sure all of their patrons are comfortable. This power isn’t being used in a positive way, because nearly all of the heat escapes into the atmosphere in seconds. Although we’re all happy to be able to eat in a smoke-free environment, is there something that these restaurant and bar owners can do to save some of the massive amounts of power their patios are using?
