Energy is an integral part of Americans’ lives and it’s an important driver of the US economy. Understanding how individuals use energy can help cut emissions and reduce energy bills. This will help to clean our air and water while providing financial incentives. The following tools and calculators will help users figure out their relationship with energy: how it’s used, how it's produced and how they can use it more efficiently.
Use Energy More Efficiently at Home
Appliance Energy Calculator — The US Department of Energy’s (DOE) appliance and electronic energy use calculator allows you to estimate your annual energy use and cost to operate specific products.
EnergySavvy — In less than five minutes get a home energy report that tells you how much you can save and what actions you can take to get the biggest bang for your buck.
Personal Energy Meter — National Geographic's Personal Energy Meter let's you see how your energy use measures up against others, and how choices you make at home and in the way you travel could help to protect the atmosphere.
Home Energy Saver — Brought to you by the Lawrence Berkeley National Laboratory, the Home Energy Saver (HES) gives users customized results about their energy use at home. The HES gives energy-saving recommendations ranked by their payback time.
Home Energy Yardstick — The EPA’s Home Energy Yardstick provides an assessment of your home annual energy use compared to similar homes. The user will receive a score from 1 to 10 and get resources about how to improve their results.
Home Energy Checklist — This is a simple checklist of energy conservation measures to use at home.
Save energy with your friends: Opower — See how your energy use stacks up against friends and homes across the US. Join groups and discover how you can save even more. (Via Facebook.)
How to Clean Up Your Power
Green Power Locator — The EPA’s Green Power Locator allows individuals to click on their state on an interactive map to find out about green power options. The Locator will generate a table that shows green power products that are available. Some choices include a mix of wind, solar and/or other renewable energy options for your electricity supply.
How clean is the electricity I use? Power Profiler — The EPA’s Power Profiler helps you learn about energy in your ZIP code. The Power Profiler will inform you of the fuel mix and emission rates for your region and compare it to the national average.
SunshineIsFree.org solar calculator — Renewable Energy Long Island (reLI), a not-for-profit organization, offers this SunshineIsFree.org solar calculator and contractor locator free of charge as a public information service.
Improve Building Energy Performance
ENERGY STAR Portfolio Manager — The ENERGY STAR Portfolio Manager helps track the energy and water use of any building. The portfolio manager is the industry standard for benchmarking and tracking energy and water consumption in any type of building.
Office Energy Checklist — The DOE provides a simple checklist of energy conservation/efficiency measures to use at the office. This document is also available as a printable flyer.
Know your Car’s Fuel Economy and Compare to Other Models
My Trip Calculator — The US DOE's calculator gives you trip directions and uses inputs about the make, model and year of your car to estimate how many gallons of gas you will use and how much that fuel will cost.
Save Money — Compare two cars with different MPGs (miles per gallons) to determine annual savings from better gas mileage.
Can a Hybrid Save Me Money? — The title says it all; the calculator compare a regular gasoline–only model with its hybrid counterpart to determine how much (or if) a hybrid will save you money.
My Plug-in Hybrid Calculator — This calculator lets you plug in your basic driving habits to see how much money and fuel a plug-in hybrid car would consume on a weekly, monthly or yearly basis.
eGallon: Compare the costs of driving with electricity — Find out how much it costs to fuel an electric vehicle in your state versus the average cost of a gallon of gasoline.
Learn More about Energy and What the Future Might Hold
U.S. Energy Information Administration’s Energy Calculators — A part of their ‘Energy Kids’ section of their website, EIA’s Energy Calculators converts from one energy unit to another. Learn how British thermal units (Btu), kilowatthours to megajoules, and even short tons of coal relate to one another.
Death and Disease from Power Plants — The Clean Air Task Force's clickable map shows the health impacts of conventional power plants.
Two Energy Futures — This interactive graphic looks at the details of a ‘fossil fuelled future’ and that of a ‘cleaner fairer future’.
Household Carbon Footprint Calculator — The EPA has an online calculator "to get a rough “ballpark” estimate of your personal or family’s greenhouse gas emissions and explore the impact of taking various actions to reduce your emissions."
CoolCalifornia.org — This California specific calculator tallies carbon emissions associated with everyday actions.
