The Issue

  • Hot water consumption!

The Larger Issue

  • Between 80 and 90 percent of the energy used to heat water is wasted.  With 110-million households in the country, that’s a lot of inefficiently used energy.
  • The cost of heating water amounts to 14% of your utility bill.

Be Part of the Solution

To help alleviate this problem you don’t have to take cold showers, eat on dirty dishes, or wear dirty clothes.  Follow these simple steps to reduce your hot-water consumption:

  • Install low-flow showerheads! These high pressure aerated showerheads deliver 2.5 gallons per minute rather than 4-5 gallons per minute and can reduce hot-water consumption by 30%. A high quality, low-flow showerhead costs around $15 and will pay for itself within 4 months.
  • Wash your clothes in cold water! Washing machines do not require a minimum temperature. In fact, cold or warm water can be used for most laundry loads. Using cold rather than hot water can amount to a savings of $60 annually, keeping 1,300 pounds of CO2 out of the air.
  • Use your dishwasher! When using a fully loaded, efficient, standard capacity EnergyStar dishwasher, you will use less energy than washing dishes by hand.
  • Lower the temperature of your water heater! If you have a booster heater on your dishwasher, lower the temperature on your water heater to 120 degrees F.
  • Install a timer on your electric water heater! Installing a $30 timer that turns the heater on in the morning and off at night can pay for itself in about 1 year.
  • Repair your leaks! Fixing a 1 drip/second leak can save you $1.00 per month.
  • Provide additional insulation to your water heater! Install an insulation blanket around your water heater to make it more efficient.

who we are:

Early in 2008, St. Petersburg College recognized its responsibility to model to our students, employees and community ways to minimize global warming emissions and provide the knowledge to our graduates to help achieve a more environmentally friendly future. Because of this, the College made sustainability (defined as meeting the needs of the present without compromising the ability of future generations to meet their own needs) a top priority. As a result, the Office for Sustainability was established.

what we do:

Working alongside internal and external partners, the Office for Sustainability focuses on the following areas of environmental stewardship: educational programs and corporate training, energy and natural resource conservation, green buildings and facilities, carbon emissions, recycling and student activities.
