Seal Up
Cracks and air leaks represent cash seeping from your doors and windows. Get rid of air leaks in doors, windows and other areas by caulking gaps and cracks. This will help decrease your heating and air conditioning bill. But make sure you use silicone sealants. Acrylic caulk tends to shrink, while silicone sealants are waterproof and won’t shrink or crack, creating less waste.

Use Less Water
Did you know that roughly 60 percent of a home's water consumption takes place in the bathroom, according to the California Urban Water Conservation Council? The largest culprit is the toilet, which accounts for 27 percent of your household supply every year. By installing low-flow toilets, showerheads and faucets, you can save thousands of gallons of water each year. In addition, replace leaky fixtures. That slow-dripping faucet can waste as much as 2,400 gallons of water per year.

Adjust the Thermostat
When adjusting your home’s thermostat, the rule of thumb should be: turn up the dial in the summer and down in the winter. Lowering the temperature by just one degree will reduce your electrical costs. And if you use a programmable thermostat, you can program your air-conditioning and heating systems to reduce output while no one is at home or at night while you sleep. Ceiling fans are also helpful in circulating the air to keep the room cool in the summer and warm in the winter.

Going green doesn't have to be overwhelming or costly. By making just a few small changes within your home, you can help decrease energy consumption and help make the world a "greener" place.
