What is Rewiring America?
Rewiring America is a leading non-profit organization dedicated to accelerating the electrification of homes, businesses, and transportation across the United States. Its core mission is to make it easier and more affordable for every American household to switch from fossil fuels to clean, electric power. This transition is seen as a critical step towards combating climate change, improving public health, and creating a more resilient energy system.
The movement advocates for policies and provides resources that support the adoption of electric appliances like heat pumps for heating and cooling, heat pump water heaters, induction stoves, and electric vehicles (EVs). It emphasizes that electrification isn't just about environmental benefits; it's also about significant financial savings for homeowners through lower energy bills and access to substantial federal, state, and local incentives.
Who should use the Rewiring America calculator? Anyone considering home upgrades, looking to reduce their carbon footprint, or wanting to save on energy bills can benefit. This includes homeowners, renters, and even contractors who want to quickly estimate the impact of electrification projects. Common misunderstandings often revolve around the upfront cost, assuming it's prohibitive, or underestimating the long-term savings and available incentives. Many also confuse electrification with simply "using more electricity," without understanding the efficiency gains of modern electric appliances or the increasing cleanliness of the electrical grid.
Rewiring America Calculator Logic and Explanation
Our Rewiring America calculator estimates the financial and environmental impact of transitioning your home to electric appliances. It does this by comparing your current energy consumption and associated costs/emissions with projected figures after installing various electrified systems.
The calculator's logic is built upon several key components:
Baseline Energy Assessment: It first estimates your current annual energy consumption (electricity, natural gas, heating oil, propane) and converts these into annual costs and carbon emissions based on average regional prices and emissions factors.
Upgrade Cost Estimation: It applies typical upfront costs for each selected electric appliance (e.g., heat pump, induction stove, EV charger).
Incentive Application: User-provided or estimated incentives (like federal tax credits from the Inflation Reduction Act) are subtracted from the total upfront cost.
New Energy Consumption & Savings: It models the energy usage of the new electric appliances, factoring in their higher efficiency. For example, a heat pump uses significantly less electricity than an electric resistance furnace for the same amount of heat. The difference in energy costs (current fossil fuel + old electric vs. new electric) determines your annual energy savings.
Carbon Reduction Calculation: By converting fossil fuel consumption to electricity, and considering the carbon intensity of the local grid, the calculator estimates the reduction in your household's annual CO2e emissions.
Financial Metrics: Finally, it calculates the net upfront cost, payback period, and total savings over a 10-year period, optionally considering loan interest.
This process provides a holistic view of your potential electrification journey, highlighting both the economic and environmental advantages. For more details on specific technologies, consider exploring our resources on Home Electrification Benefits.

Practical Examples of Rewiring America Impact
Example 1: Switching from Gas Furnace to Heat Pump
Scenario: A homeowner with a 2,000 sq ft home currently uses a natural gas furnace for heating and a traditional AC unit for cooling. Their average monthly gas bill is $100, and electricity bill is $120. They decide to install a high-efficiency heat pump HVAC system and qualify for $7,000 in incentives.
Inputs:
Home Square Footage: 2000
Current Heating Fuel: Natural Gas Furnace
Average Monthly Gas Bill: $100
Average Monthly Electricity Bill: $120
Upgrade: Heat Pump (HVAC) (checked)
Upfront Incentives: $7,000
Estimated Results (Approximate):
Net Upfront Cost: ~$8,000 - $10,000
Annual Energy Savings: ~$800 - $1,200
Annual Carbon Reduction: ~3,000 - 5,000 kg CO2e
Payback Period: ~7-12 years
Effect of changing units: In this calculator, financial units are fixed to USD. However, energy savings are calculated internally in kWh/therms/gallons and then converted to USD. If electricity prices were significantly higher (e.g., $0.30/kWh), the annual savings might decrease or even turn into a slight increase, despite the efficiency gains, due to the shift from cheaper gas to more expensive electricity. Conversely, if gas prices spiked, savings would be much higher.
Example 2: Comprehensive Electrification with EV Charging
Scenario: A homeowner with an older electric resistance water heater and an electric stove wants to fully electrify. They have a 2,500 sq ft home, a monthly electricity bill of $200, and no gas. They plan to install a heat pump HVAC, a heat pump water heater, an induction stove, and a Level 2 EV charger. They expect $10,000 in combined incentives and a 3% loan for 15 years.
Inputs:
Home Square Footage: 2500
Current Heating Fuel: Electric Baseboard
Average Monthly Electricity Bill: $200
Upgrades: Heat Pump (HVAC), Heat Pump Water Heater, Induction Stove, EV Charger (all checked)
Upfront Incentives: $10,000
Loan Interest Rate: 3.0%
Loan Term: 15 years
Estimated Results (Approximate):
Net Upfront Cost: ~$10,000 - $15,000
Annual Energy Savings: ~$1,000 - $1,500 (even with EV charging, due to HP efficiency)
Annual Carbon Reduction: ~4,000 - 6,000 kg CO2e
Payback Period: ~8-14 years
This example demonstrates how multiple upgrades, even those increasing electricity demand like EV charging, can still lead to overall savings and substantial carbon reductions due to the efficiency of modern electric appliances and the displacement of fossil fuels.

Key Factors That Affect Rewiring America Calculations
The outcomes of your home electrification journey, and thus the results from any Rewiring America calculator, are influenced by a multitude of factors. Understanding these can help you optimize your choices and maximize benefits:
Current Energy Sources & Costs: The biggest driver of savings is often replacing expensive or high-emission fossil fuels (like heating oil or propane) with efficient electricity. If your current energy mix is already cheap and low-carbon, savings might be less dramatic. Regional electricity, gas, oil, and propane prices fluctuate significantly.
Appliance Efficiency: The specific efficiency ratings of the new electric appliances (e.g., SEER2/HSPF for heat pumps) directly impact energy consumption and, consequently, your savings. Higher efficiency means greater savings.
Home Insulation & Air Sealing: A well-insulated and air-sealed home requires less energy to heat and cool, making any HVAC system (including a heat pump) more effective and reducing its operational cost. This foundational work can amplify electrification benefits.
Local Climate Zone: Heat pump performance varies with outdoor temperature. In very cold climates, backup heating might be needed, which can affect electricity consumption. However, modern cold-climate heat pumps are highly effective even in sub-zero temperatures.
Available Incentives & Rebates: Federal programs (like the Inflation Reduction Act), state tax credits, and local utility rebates can drastically reduce the upfront cost of electrification, significantly improving the payback period and ROI. Missing out on these can make projects seem more expensive. Explore IRA Tax Credits Explained.
Electricity Grid Carbon Intensity: The amount of carbon emitted per unit of electricity generated varies widely by region, depending on the mix of power sources (e.g., coal, natural gas, solar, wind). A cleaner grid means greater carbon reduction benefits from electrification.
Financing Options: Interest rates and loan terms can impact the overall cost of upgrades. Low-interest loans or on-bill financing programs can make electrification more accessible and affordable.
Household Habits & Usage: How you use your appliances (e.g., thermostat settings, hot water usage, EV mileage) will directly affect your energy consumption and, therefore, your bills and emissions.
Future Energy Price Trends: Long-term savings projections are sensitive to assumptions about future electricity and fossil fuel price changes. Electrification generally hedges against volatile fossil fuel markets.
Maintenance Costs: While not directly calculated here, modern electric appliances generally have lower maintenance needs than their fossil fuel counterparts, contributing to long-term savings.
Considering these factors holistically will give you the most accurate picture of your potential rewiring America journey. For more on reducing your environmental impact, see our guide on Reducing Carbon Footprint Home.
Frequently Asked Questions (FAQ) about Rewiring America and Home Electrification
