Use Energy Star Products
According to energystar.gov, folks saved upwards of $30 million on their utility bills and helped to reduce greenhouse gases by using Energy Star-rated products. These super-efficient products include CFL and LED light bulbs, household appliances, building materials such as windows and doors and HVAC equipment among many others. Not only is switching to Energy Star products one of the best frugal living tips, but it also allows you take advantage of their energy savings and may qualify you for the Residential Renewable Energy Tax Credit.
Switch to CFL Bulbs
CFL bulbs will provide 10,000 hours of light and use $10.40 of electricity (at 8 cents per kilowatt hour). To get the same output with incandescents, you would have to use seven bulbs, which would cost less up front, but the electricity would cost $48.
