There are a number of measures you can take to make your household systems more energy-efficient and significantly reduce your carbon dioxide footprint. Improvements to your household systems include maintaining and upgrading your heating and cooling equipment, making your hot water heater more efficient, installing energy efficient lights, sealing air leaks, replacing aging appliances with new, more energy-efficient models, and other measures that make up a "whole-house" energy efficiency plan. Below are the articles on this site that will give you some great ideas on how you can begin to make your home more energy efficient and reduce your carbon footprint.

The Central Indiana Environmental Education Program (CIEEP) is designed to teach individuals, households and communities cost-effective ways to lower their energy bills by using energy more efficiently and reducing their overall energy consumption.
Simple changes in our daily routines not only save us money on our gas and utility bills – they also improve the health of individuals, communities, and our environment by reducing toxins in our air and greenhouse gas emissions responsible for global warming.
Thanks to grants from the Nina Mason Pulliam Charitable Trust, Efroymson Family Fund, a CICF fund, and Normandie Foundation, Citizens Action Coalition Education Fund was able to establish the Central Indiana Environmental Education Program (CIEEP). The goals of this program are as follows:
"The findings of the IPCC [Intergovernmental Panel on Climate Change], the consensus estimate of the world’s scientists, couldn’t be any clearer: human activities are altering our atmosphere, and the planet is warming. Unless we act now, with great urgency, costly and disruptive impacts all over the world are inevitable. We have no choice but to act.
Almost half of all homes in the U.S. have inefficient, single-pane windows. Inefficient windows can account for up to 25% of your heating bill in the winter, and can make your air conditioner work up to three times harder in the summer. Although high performance windows may cost more initially, they save you money in the long run. In addition, they increase the value of your home.
Our Living Lean & Green workshop introduces you to the impact of global warming on our community, and to a set of simple tools to reduce your energy consumption and save you money. The five-session workshop is designed to help you reduce your household carbon dioxide “footprint” by at least 5,000 pounds by going on a “low carbon” diet.
More energy dollars go towards your heating and cooling system than any other system in your home. "Typically, 56% of your utility bill goes for heating and cooling. What’s more, heating and cooling systems in the United States together emit over a half billion tons of carbon dioxide into the atmosphere each year, adding to global warming.
After household heating and cooling, water heating is the largest energy user in your home, representing over 13% of your annual energy bill, and a significant contributor to household CO2 emissions. "If your water heater is more than 10 years old it is likely running at less than 50 percent efficiency—wasting energy and money—but most people don’t replace their water heater until it fails.
Lighting is the third largest energy user in your home, representing approximately 10% of your annual energy bill. "Making improvements to your lighting is one of the fastest ways to cut your energy bills. . . . Using new lighting technologies can reduce lighting energy use in your home by 50% to 75%. Advances in lighting controls offer further energy savings by reducing the amount of time lights are on but not being used."
Appliances such as your refrigerator, clothes washer and dryer, dishwasher and electronics (TV, computer, audio and video systems, etc.) account for about 20% of your household’s annual energy bill. "Together, these items account for nearly eight tons of heat-trapping emissions per household per year."
The first step to taking a whole-house energy efficiency approach is to find out which parts of your house or apartment use the most energy. A home energy audit will identify those areas, and through your own efforts, your local utility, or the assistance of a qualified professional, you can take cost-effective measures to reduce your energy costs and hence, your CO2 footprint.
