Allison Kaplan Saint Paul Pioneer Press Hot air isn't the only thing blowing out the cracks and crevices in your home.
Every leak means money out the window, too.
Those leaks could be more expensive than usual this winter, with natural gas costs predicted to increase 30 to 50 percent over last year. Here are 10 ways to save on natural gas, without investing thousands of dollars. Keep in mind that both the estimated savings and cost of these measures can vary depending on the house and energy consumption. For every eight hours you turn down the heat, you'll save about 1 percent per degree. If you maintain 65 degrees as your high temperature and turn the thermostat down to 60 or 55 while you're away or asleep, you can save as much as 25 percent on your heating bill.
