Fuel Comparison Tables

Whether you're a contractor looking to best serve our shared customers or a customer yourself, it's important to take a look at how electricity compares to fossil fuels. As part of that process we encourage you to:

  • Learn about rebates and programs that offer energy- and money-saving opportunities.
  • Calculate savings based on various rate options to help find the right fit.

Now, let's see how electricity compares to fossil fuels.

Btu content

Amount Unit Source
1,000,000 Btu / MCF Natural gas
    91,800 Btu / gallon Propane
  140,000 Btu / gallon Heating oil
     3,413 Btu / kWh Electricity

 

Breakeven points and kilowatt-hour equivalents

Check out this summary of controlled-service rates and associated riders and adjustments to get a more accurate price for your comparison.

To calculate the break-even point of electricity compared with natural gas, find the price per kilowatt-hour paid (prices will vary by rate) and the efficiency level of the fossil fuel-operated equipment you are comparing. The price shown is the price fossil fuels must reach to break even with electricity prices.
