Do your part to reduce waste by choosing reusable products instead of disposables such as plastics cups. Whenever you can, recycle paper, plastic, newspaper, glass and aluminum cans. Also, do not request for plastic bags when buying little quantity of products.

Adding insulation to your walls, and installing weather stripping or caulking around doors and windows can lower your heating costs more than 25 percent, by reducing the amount of energy you need to heat and cool your home.

Turn down the heat while you’re sleeping at night or away during the day, and keep temperatures moderate at all times.

3.Change a Light Bulb

Wherever practical, replace regular light bulbs with compact fluorescent light (CFL) bulbs. CFLs last 10 times longer than incandescent bulbs, use two-thirds less energy, and give off 70 percent less heat.

4. Drive Less and Drive Smart

Less driving means fewer emissions. Besides saving gasoline, walking and biking are great forms of exercise.

When you do drive, make sure your car is running efficiently. For example, keeping your tires properly inflated can improve your gas mileage by more than 3 percent.

5. Buy Energy-Efficient Products

When it's time to buy a new car, choose one that offers good gas mileage. Home appliances now come in a range of energy-efficient models, and compact florescent bulbs are designed to provide more natural-looking light while using far less energy than standard light bulbs.
Avoid products that come with excess packaging, especially molded plastic and other packaging that can't be recycled.

6. Use Less Hot Water

Buy low-flow showerheads to save hot water. Wash your clothes in warm or cold water to reduce your use of hot water and the energy required to produce it. Use the energy-saving settings on your dishwasher and let the dishes air-dry.

7. Use the "Off" Switch

Save electricity and reduce global warming by turning off lights when you leave a room, and using only as much light as you need. And remember to turn off your television, video player, stereo and computer when you're not using them.
It's also a good idea to turn off the water when you're not using it. While brushing your teeth, shampooing the dog or washing your car, turn off the water until you actually need it for rinsing.

8. Plant a Tree

During photosynthesis, trees and other plants absorb carbon dioxide and give off oxygen. They are an integral part of the natural atmospheric exchange cycle here on Earth, but there are too few of them to fully counter the increases in carbon dioxide caused by automobile traffic, manufacturing and other human activities.

9. Get a Report Card from Your Utility Company

Many utility companies provide free home energy audits to help consumers identify areas in their homes that may not be energy efficient.
