How can you burn calories and make money at the same time? There's probably countless ways but here's one idea that will also help slow global warming to boot.How long would it take to replace all the light bulbs in your home? And how many calories would you burn if it took you two hours? We're talking about a potential piddly 300 to 500 calories depending on your weight and how much you'd have to exert yourself.
But the savings to your budget would be much more impressive. If you replaced all your regular bulbs with compact fluorescent light bulbs you would save 50 cents to 75 cents per month per bulb. That adds up to more than a few dollars over the year.
More importantly we would make a significant contribution to slow global warming. These bulbs use only about one third of the electricity as the regular bulbs in our homes.
It's been estimated that if each home replaced only one bulb, it would be the equivalent of taking a million cars off the road in terms of global warming impact.
