638065182785130000 - CopyWhy Electric?

Natural gas burned in buildings accounts for nearly 30% of all greenhouse gas emissions in San Carlos. Reducing these emissions requires making buildings more energy efficient and converting gas appliances to electric. The modern, all-electric home is comfortable, energy efficient and healthy for your family and the planet. By using highly efficient electric appliances you won’t be combusting gas in the home. Instead, as a Peninsula Clean Energy customer, you’ll be using 100% carbon-free electricity.

Frequently Asked Questions
How much does it cost to electrify my home?

To fully electrify a home in San Mateo County is around $30,000 but can vary depending on the size and age of the home. However, most homeowners will go electric when replacing existing gas appliances that have reached their end of life. When accounting for the many rebates and incentives available to San Carlos residents, replacing a gas appliance with a clean, electric alternative can be the most cost-effective option rather than staying with gas.

Will electrifying my home raise my utility bills?

Electricity is more expensive than gas but electric appliances are much more efficient to operate. Studies show that on average there is not a significant impact either way in terms of savings or increased bills cost associated with electrification. See the table below for a breakdown based on appliance.


Bill Impact

Space heating with heat pump vs furnace

$28/month savings - $6/month increase

Heat pump water heater vs gas storage water heater

$8/month - $5/month savings

Electric cooktop vs gas cooktop

~$5/month increase

Electric clothes dryer vs gas clothes dryer

~$10/month increase

What about power outages?

If there is a power outage and your home is not equipped with a generator or battery backup, you will not be able to use your electrical appliances. However, since all modern gas appliances use electric ignition for fire safety, they won’t be able to ignite during a power outage either. The exception is a gas stove which can be lit manually but is not recommended to operate without a hood vent to remove harmful pollutants.

Is the grid ready for all-electric buildings?

The California grid is most strained on the hottest days when air conditioners across the state are on full blast. Electric homes using heat pumps do not have a significantly higher electricity demand compared to a home with AC and can be more easily accommodated in the short term. In the long term, electrifying homes will add loads during the winter but at a pace that grid operators and regulators can plan for and accommodate.

Will I need a panel upgrade to electrify my home?
Not necessarily. It is possible to fully electrify a home and add EV charging on a smaller 100 amp service. When electrifying a home on 100 amps consider following these recommendations to avoid a panel upgrade:
  • Improve the energy efficiency of your home before electrifying to reduce your home's heating and cooling needs
  • Avoid split ovens / cooktops in favor of slide-in ranges
  • Avoid installing ultra fast EV charging (60 amps or higher)
  • Consider amp saving technologies like a circuit pauser, circuit sharer, or smart panel

For more information, checkout Peninsula Clean Energy's Guidelines for Home Electrification or Redwood Energy's Watt Diet Calculator. The best way to find out if you need a panel upgrade is to speak with an electrician or energy expert.

What are the health benefits of an all-electric home?

Indoor appliances impact the quality of our indoor air, among other concerns. Natural gas and propane stoves release carbon monoxide, formaldehyde, and other harmful pollutants that can be toxic to people and pets. Using a wood stove or fireplace to cook can result in high levels of indoor air pollution as well. Electric appliances do not combust fossil fuels and therefore do not produce any pollutants in your home or in your community.

What is a heat pump and how does it work?

A heat pump is the same technology as an air conditioner but can also run in reverse, heating a space rather than cooling it. A ducted heat pump can also use ducts to distribute heat around a house like a central HVAC system with a gas furnace, but is much more efficient. Another type of heat pump, the mini-split, can distribute refrigerant to different rooms to heat and cool them individually, allowing for each room to be set to different temperatures.

I thought natural gas was clean?

Unfortunately, no. Natural gas is a fossil fuel, created by decomposing organic matter similar to crude oil and coal. Burning natural gas releases heat-trapping carbon into the atmosphere. If natural gas leaks into the atmosphere without combusting (in the form of methane) it is more than 25 times as potent a greenhouse gas as carbon dioxide.

What about the emissions from generating electricity? Where does my electricity come from? 
In San Carlos we are supplied with 100% greenhouse gas free energy from Peninsula Clean Energy who purchases power from sources such as wind, solar, batteries, geothermal, and hyrdo.
