On average, a standard bathroom faucet uses about 2 to 2.5 gallons of water per minute. By turning off the tap while brushing your teeth (typically a 2-minute process), a person can save around 4 to 5 gallons of water each time they brush their teeth. If someone brushes twice a day, that's approximately 8 to 10 gallons saved daily. As this is an introductory habit most users already do, we assume that users maintain this habit nearly every day the a year.

If a user installs bathroom faucet aerators, 1 kitchen aerator, and 1 low flow shower head, they’ll save 8000 gallons of water on average over the course of a year.

An average shower head in California has a flow rate of 1.8 gallons per minute (gpm). Reducing shower time from 10 minutes to 5 minutes results in 9 gallons of water saved. To annualize, we assume each user maintains their short shower habit twice a week for a year.

Switching to OhmConnect can save an average California household about 581 kWh annually, reflecting a 10% reduction in energy consumption based on typical yearly usage of 5812 kWh.

Turning off five 60-watt incandescent bulbs for two hours daily saves 0.6 kWh of energy per day. As this is an introductory habit most users already do, we assume that users maintain this habit nearly every day the a year.

For every gallon of water saved, about 0.003 kWh of energy is conserved. For 8 to 10 gallons saved per day, that’s around 0.024 to 0.03 kWh per day. As this is an introductory habit most users already do, we assume that users maintain this habit nearly every day the a year.

Using low-flow gear to save 8,000 gallons of water can result in an energy savings of 24 kWh, based on the energy intensity of water treatment and distribution.

Saving 9 gallons of water by shortening showers from 10 to 5 minutes can save approximately 1.53 kWh of energy, due to the energy used to distribute and heat water. To annualize, we assume each user maintains their short shower habit twice a week for a year

We assume that private automobile travel emits approximately 404 grams of CO₂-equivalent (CO₂e) per mile, whereas public transportation travel emits approximately 100 grams CO₂e per mile. Under these assumptions, substituting one mile of private vehicle travel with public transportation results in an emissions reduction of approximately 304 grams of CO₂e per mile. To annualize, we assume that each user engages in this transportation switch once per week for a year.

Composting food waste instead of sending it to landfill reduces emissions by approximately 0.44 kg CO₂e per kilogram of food waste. For each action in this analysis, we assume that the average participant generates 1.23 kg of food waste per day, derived from the U.S. average of 19 pounds of food waste per household per week. To annualize, we assume users who were already composting continue to do so every day for a year. For new composters, we only include impact data for those who have logged 6+ times on the platform.

The average Californian household participating in OhmConnect could prevent 460 pounds of CO₂e emissions annually (approximately 209kg or .2 tons)

Reducing the daily operating time of just five 60-watt incandescent bulbs by two hours results in a reduction of .138kg CO2e per day. As this is an introductory habit most users already do, we assume that users maintain this habit nearly every day the a year.

To calculate, we multiple gallons saved (8 to 10) by the energy intensity (0.003 kWh per gallon), resulting in 0.024 to 0.03 kWh saved per day. CO₂ emissions saved were estimated by multiplying the energy saved (0.024 kWh) by California's average carbon intensity (0.23 kg CO₂ per kWh), yielding approximately 0.00552 kg of CO₂ saved per day. As this is an introductory habit most users already do, we assume that users maintain this habit nearly every day the a year.

Energy savings for water treatment and distribution were calculated by multiplying the gallons saved (8,000) by the energy intensity (0.003 kWh per gallon), resulting in 24 kWh saved. CO₂ emissions saved were estimated by multiplying energy saved by California's carbon intensity (0.23 kg CO₂ per kWh), resulting in 5.52 kg (0.00552 metric tons) of CO₂ saved.

An average shower head in California has a flow rate of 1.8 gallons per minute (gpm). Reducing shower time from 10 minutes to 5 minutes results in 9 gallons of water saved. To annualize, we assume each user maintains their short shower habit twice a week for a year.
