“every generation needs a new revolution.” —thomas jefferson, third president of the united states


If you take steps towards a more sustainable lifestyle, the results are indeed measurable. By using the following links, you can calculate the amount of carbon dioxide you save from entering the atmosphere (and what that means in every day terms), how many calories you burn by biking to work, or how much your bills can be reduced by turning off the lights or faucet.


Energy & Carbon Calculators

The Nature Conservancy's Carbon Footprint Calculator — The first step to lowering carbon emissions is understanding your carbon footprint. This tool helps you estimate your individual or household carbon footprint and shows how different lifestyle choices, household features, and new technologies affect the size of your footprint.

Greenhouse Gas Equivalency Calculator — Did you ever wonder what reducing CO2 emissions by 1 million metric tons means in everyday terms? This tool can help you do just that. Use this calculator to convert measurements of greenhouse gas (GHG) emissions from one measurement unit or number into different but equivalent measurement units that are easier to understand for your audience or for your own calculations.

U.S. Department of Energy — The calculators and tools on these pages can help you evaluate your energy use and whether energy efficient products or renewable energy are right for you. Calculate energy use for buildings, homes, industries, and vehicles.

Infinite Power’s Energy Calculators & Software — These interactive calculators help you understand energy production and consumption in a whole new way. Use them to develop a personal profile of your own energy use. Various software programs have been included in this section for your information.

Cost-Saving Calculator

GE’s Energy Cost Calculator — This calculator is designed to give an idea of the costs of various daily things we do in our homes that are electrical in nature. This calculator is generic in that it is based on the national average for kWh (currently $0.10120 per kWh), and your entered values to determine your cost for electrical power. How much does it cost to wash a load of clothes or sleep under the electric blanket? What does it cost to leave a light on all night?

We have collected national average values of energy use to find out how much you are paying to operate the different devices in your home. If you know the exact information for your device or appliance, you might want to see our equipment cost calculator for commercial use or our appliance cost calculator for residential use. You might also find our energy pollution and carbon pollution calculators interesting sources of additional information.
