Energy Conservation
Energy Sources
Renewable energy sources
 Wind (wind power)
 Water (hydropower)
 Sun (solar)
 Vegetation (biomass)
 Internal heat of the earth (geothermal)
Non-renewable energy sources
 Oil
 Gas
 Coal
 Nuclear power plants
We use energy
 To Light our homes
 To Power machinery in factories
 To Cook our food
 To Play music
 To Operate televisions
In a home
 Air conditioner and heater = 50%
 Water heater = 20%
 Lighting and small appliances = 10%
 Refrigerator = 8%
 Other = 5%
 Ovens and stoves = 4%
 Clothes dryer = 3%
Why is energy conservation important?
 Nonrenewable sources impacts the environment,
 Fossil fuels contributes to air and water pollution,
 Carbon dioxide is produced when oil, coal, and gas combust.
 Carbon dioxide in the atmosphere acts as a transparent blanket-"greenhouse effect.“
 The sulfur dioxide reacts with water and oxygen in the clouds to form precipitation known as "acid rain.“
How can pollution prevention help you?
Changing What You Use…
 Walk, ride a bicycle, or use mass transit instead of driving-60 percent of air pollution in our cities.
 Install compact fluorescent light bulbs-last 10 times longer than incandescent light bulbs.
 Air-dry your clothes
 Install a programmable thermostat-automatically adjusts the temperature
 Buy energy-efficient appliances.
Changing What You Do…
 Set the thermostat to 68 °F in winter, down to 55° F.
 Insulate the ceiling, walls, and floor of your home.
 Plant a tree next to a window
 Recycle items such as newspaper, aluminum cans, and plastic bottles.
 Wash clothes in cold water and only in full loads.
 Use energy-saving settings on washing machines, dishwashers, and clothes dryers.
Improving Your Housekeeping…
 Turn down the water heater thermostat to 120° F.
 Turn off lights when leaving a room.
 Close heating vents and close doors to unused rooms.
 Close drapes and windows during sunny summer days and after sunset in cooler weather.
 Stop air leaks around windows and doors with caulk or weather stripping.
 Clean or change air filters on your air heating system
