1. Compact Fluorescent Bulbs

“If every American home replaced just one light with an ENERGY STAR light, we would save enough energy to light more than 3 million homes for a year, about $700 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions per year, equivalent to the emissions of about 800,000 cars.” – [1]

2. Programmable Thermostat

“The average household spends more than $2,200 a year on energy bills – nearly half of which goes to heating and cooling. Homeowners can save about $180 a year by properly setting their programmable thermostats and maintaining those settings.” [2]

*The $180 savings assumes a typical, single-family home with a 10 hour daytime setback of 8° F in winter and setup of 7° F in summer, and an 8 hour nighttime setback of 8° F in winter and a setup of 4° F in summer.

*$180 is the equivalent of roughly 1,588kwh of electricity usage based on an average price of 11.33 cents per kwh. Average price per KWH is 11.33 cents according to: [3]

*On average electric heating and cooling consumes 1.297 lbs CO2 per kWh. This means roughly 2,059lbs of CO2 saved per person per year. We calculate emissions from electricity generation based off of state-based figures from Department of Energy’s Energy Information Administration. On average, electricity sources emit 1.297 lbs CO2 per kWh (0.0005883 metric tons CO2 per kWh). State CO2 emissions per kWh may vary greatly in accordance with the amount of clean energy in the energy supply (Vermont, Idaho: .03 lbs/kWh; North Dakota: 2.24 lbs/kWh).

*Based on these figures, If 20M people did this, we would save $3,600,000,000 ($180×20,000,000) per year and 41,180,000,000lbs (2,059lbsx20,000,000) of CO2

*According the EPA, annual emissions from a typical passenger vehicle should be equated to 5.5 metric tons(12,125pounds) of carbon dioxide. (41,180,000,000lbs/12,125lbs=3,396,288cars)

3.Water Heater
*For every 10 degrees you reduce your hot water heater’s temperature, CO2 emissions are reduced by about 3-5 percent, or 733 pounds annually. If you have an electric water heater, you will also reduce your electric bill by roughly $59 per year. -[4]

*CO2-savings calculation assumptions: A kilowatt-hour of electricity, 1.297lbs CO2.(same as above)

*Cost-savings calculation assumptions: A kilowatt-hour of electricity, 11.33 cents. (same as above)

*If 20M people did this the net savings would be $1,180,000,000 ($59×20,000,000) and 14,600,000,000lbs (733lbsx20,000,000) of CO2.

This is the equivalent of 1,204,123 cars yearly emissions (14,600,000,000/ 12,125lbs)

4. Low Flow Shower Heads

*Switching from a traditional 8gpm showerhead (80gallons for a ten minute shower) to a low flow 2.5gpm shower head (25 gallons for a ten minute shower) you save on average 55gallons each day (assuming you take one 10min shower per day.)

*Home water costs on average $2 for every 1,000 gallons or .2 cents per gallon. [5]

*Based on 55gallon per day savings, 20,075gallons of water would be saved each year (55gallonsx365days). This is equivalent to $40.15 per year (20,075gallons x .2cents)

*According to FlexYourPower.org each gallon of water you use costs you 0.129kwh of electricity. Using the 11.33cents per kwh as used in the other calculations, each wasted gallon costs you 1.4cents in electricity. So if you save 20,075gallons per year, you are saving roughly $280 per year on electricity. (20,075gallons x 1.4cents)

*If 20Million people used low flow shower heads and took on average one ten minute shower per day. We would save 401,500,000,000 Billion Gallons of water

*If 20Million people used low flow shower heads and took on average one ten minute shower per day, we would save $6,400,000,000 (($40 per year for water + 280 per year electricity)x20Million).
