Gyms are the epitome of inefficiency. Lights blaze upwards of 18 hours a day. Most exercise machines, television sets, fans, and stereos are left on whether in use or not. The average treadmill uses around 1500 watts -- the equivalent of 15 incandescent light bulbs! Stationary bikes use a mere 10% of their energy to run the machine and dissipate the rest as heat. When people run, bike or elliptical to burn their own energy, they require incredible additional energy input to operate the machines. So much energy going to waste! What’s an eco-conscious exerciser to do during the cold months?
