Lighting accounts for 34% of US electricity usage and 20% of your electric bill. Therefore, it is paramount that we take measures to use this large percentage of electricity properly. We can start with the simplest green tip, turning off the light when you leave a room. Apart from "don’t litter," "turn off the light" is one of the simplest and most effective tips that there is. But I’ll try and give you a few more tips than just that.
Making Your Household Lighting More Efficient
1. Use CFL or LED light bulbs.
2. Employ motion sensors in little-used areas of the house, to ensure that the lights go off when you leave the room.
3. Employ more natural light. You can use skylights, solar tubes or mirrors.
Paint the walls of your house light colors. This will reflect more light, allowing you to use lower wattage bulbs and/or LEDs.
4. Keep your walls clean. Dirty walls will reflect less light.
5. Repaint walls every few years. Make sure to use Low/No VOC paints.
6. Clean fixtures every 6 months. If your fixtures are dirty, you aren't receiving the full benefit of your lights, but you are still using full power.
7. Replace yellow lenses.
8. When you buy new light fixtures, choose EnergyStar models.
9. Light-colored curtains allow daylight to penetrate, they keep your house private and reflect heat.

Insulation is so important to energy-efficiency and reducing global warming that the government will help you insulate your house. Over half of your home's energy consumption goes towards heating or cooling your domicile. That's why proper insulation is paramount to green living. Switching off lights and unplugging appliances are all well and good, but if you want to make the biggest difference in your home, insulate it. Check out these green forms of insulation.
1. Spray Foam Insulation
Spray foam insulation can be added to existing homes. Insulating an old house is greener than building a new one. Spray foam will last indefinitely, so your home will be warm for generations to come. Spray foam doesn't harm indoor air quality, it doesn't promote bacterial growth and it keeps moisture and rot out.
2. Cellulose Insulation
Cellulose Insulation, sometimes called newspaper Insulation is insulation made from three-fourths recycled content: Newspapers, corncobs, straw, etc. The last fourth is flame-resistant chemicals.
The materials that compose cellulose don't contribute to global warming, and they are not known to cause health problems in those who manufacture the product. Plus, manufacturing cellulose insulation doesn't require as much energy as manufacturing other forms of insulation. The incombustible chemicals, borax and boric acid, are also easier to mine than the chemicals found in fiberglass insulation.
3. Denim Insulation
If you like post-consumer insulation, then you'll love denim insulation. Old blue jeans are used to make natural fiber insulation. This insulation is made out of 85% post-industrial cotton fiber and is treated with a natural fire retardant. There are no VOC problems with this insulation and you can recycle it.
Straw bale houses are truly amazing. Straw insulation has the capacity to decrease heating costs by seventy-five percent. Straw has long been considered an agricultural waste product, so insulating with it reduces waste. You'll also be happy to know that straw-bale insulation is fire resistant, provides good air quality and reduces noise pollution.
