Sustainability Trends

Ideas for a Greener Home

  • Reduce, reuse, recycle
  • Use eco-friendly cleaning supplies
  • Favor cloth over paper products
  • Chlorine-free baby diapers/ wipes
  • Choose natural lawn care - stop using pesticides and synthetic fertilizers
  • Use biodegradable detergent and oxygen bleach
  • For clean, safe drinking water without all of the waste - use a water filter and a reusable bottle

Energy Saving Ideas

  • Use CFL or LED light bulbs
  • Use Energy Star labeled equipment
  • Turn off all home and office equipment when not in use
  • Turn off lights when not in use
  • Turn down the thermostat - lowering it by just one degree can reduce heating energy costs significantly
  • Avoid phantom loads (electrical equipment that still uses energy even after turned off) by using a power strip
  • Reduce your water heater temperature from 140 degrees to 120 degrees
  • Install double pane windows
