Measure your environmental impact and find ways to save money while helping the planet.
Understanding your environmental footprint is the first step toward reducing it. Our environmental calculators help you quantify the impact of your daily choices — from the energy your home consumes to the emissions from your commute — and identify the changes that will make the biggest difference for both the planet and your wallet.
Sustainability and savings often go hand in hand. Solar panels reduce both your carbon footprint and electricity bills. Electric vehicles cost less per mile than gas cars. Energy-efficient appliances use less electricity while performing the same (or better). Our calculators help you see the financial return on green investments, making it easier to justify the upfront costs with long-term savings data.
The most impactful actions are: reducing driving (switch to public transit or EV), eating less meat (especially beef, which produces 27 kg CO₂ per kg), improving home insulation, switching to renewable energy, and reducing air travel. Even small changes like LED bulbs and efficient appliances add up.
In most sunny areas, solar panels pay for themselves in 6-10 years through electricity savings and net metering credits, then continue saving money for 15-20+ more years. With the 30% federal tax credit (ITC), the payback period is even shorter. Our solar calculator helps you estimate savings for your specific location and energy usage.
A carbon footprint is the total amount of greenhouse gases (measured in CO₂ equivalents) produced by your activities. The average American generates about 16 metric tons of CO₂ per year — more than double the global average. Transportation, home energy, diet, and consumption are the main contributors.
At the US average electricity rate of $0.16/kWh, charging a typical EV (60 kWh battery) from empty to full costs about $9.60, giving you roughly 250 miles of range. That is about $0.04 per mile, compared to $0.12-0.15 per mile for a gas car. Charging at home overnight on off-peak rates can be even cheaper.
Start by reviewing your utility bills for annual kWh usage, then divide by your home square footage. The average US home uses about 10-12 kWh per square foot per year. Values significantly above this suggest opportunities for insulation, appliance upgrades, or behavioral changes.
