Introduction Our group has examined different light bulbs

and have determined which will be best for anyone to use.

Project Overview Different light bulbs have been examined to see

which one is more cost efficient, safer for the environment, and which one last longer.

Project Overview (continued)Incandescent Bulb Compact Fluorescent Light

Electronic Ballast Tube

Community Aspect Our group has examined which light bulbs

are more affordable, safer to use and safer for the environment.

Course content objectives Inform the general population ( i. e.

classmates, citizens) about different light bulbs in order that they can make good decisions about which light bulbs are the best to use.

Methods Created a plan Researched for information Interviewed community contacts

Technology to Use We have used various resources including the

internet and certain books and periodicals in the library that related to light bulbs.

CFLs VS. IncandescentCFLs

They produce about 75 percent less heat, so they're safer to operate and can cut energy costs associated with home cooling.

A single CFL will prevent 10 convention bulbs from being produced, transported, and discarded in a landfill; 220 lbs. of coal from being burned; and 450 lbs. of greenhouse gasses from reaching the air.

CFLs emit the same amount of light as incandescent bulbs but use 75-80% less electricity

If the incandescent light bulbs are banned, it would eliminate the need to build 80 coal-fired power plants, prevent about 158 million tons of carbon dioxide annually and save consumers $18 billion a year in electric costs.

CFLs VS. IncandescentIncandescent

Approximately 90%-95% of the power consumed by an incandescent light bulb is emitted as heat, rather than as visible light.

Standard light bulbs will lose up to 45% of their light output with use. However, you continue to pay for the full wattage of the bulb!

Incandescent bulbs currently consume 42 percent of the electricity generated in the United States, but only provide 12 percent of the country's artificial light.

There is enough mercury in a single fluorescent tube to contaminate up to 30,000 liters of water beyond a safe standard for drinking.

What are the benefits of using CFLs?

If you switch your light bulbs at home, you will save money and energy. If 20% of the United States population changed 5 light bulbs, here is what would happen:

Dollars Saved Each Year in Electricity Bills ($):

3,431,969,348

Air Pollution Reduction (lbs of CO2):

46,695,680,892

Air Pollution Reduction Equivalence (number of cars removed from the road for a year):

4,039,419

Air Pollution Reduction Equivalence (acres of forest):

6,367,882

What is NWACC doing?NWACC is planning to switch from T12 to T8.The existing 4-lamp fixtures with 40w costs

49.28 per year for only one fixture.The new t8 4-lamp fixtures with 32w cost

30.52 per year for only one fixtureNWACC will also save $18.76 a year for one

fixture.T8 fixtures will also provide better color

rendering and quieter lamp/ballast operation.

Why should every one switch to CFLs?

Compact Fluorescent light bulbs last 8 to 12 times longer than a conventional bulb.

An ENERGY STAR-qualified Compact Fluorescent light bulb can save an average of $30 or more in electricity costs over its lifetime

ENERGY STAR-qualified bulbs and fixtures produce about 70% less heat, so they're safer to operate and can cut energy costs associated with home cooling

A single CFL will prevent 10 convention bulbs from being produced, transported, and discarded in a landfill

The proper way to dispose of light bulbs

There is a small amount of mercury in compact fluorescent light bulbs so it is important to dispose of them properly.

1. SWEEP UP, DO NOT VACUUM, ALL THE GLASS PARTICLES2. PLACE BROKEN PIECES IN A SEALED PLASTIC BAG3. WIPE THE ARE WITH A DAMP PAPER TOWEL OR STICKY

TAPE TO PICK UP ANY STRAY PIECES OF GLASS OR FINE PARTICLES. PUT THE TOWEL OR TAPE IN THE PLASTIC BAG

4. OPEN WINDOWS TO ALLOW THE ROOM TO VENTILATE FOR ABOUT 15-30 MINUTES

5. WASH YOUR HANDS AFTER CLEANING UP THE GLASS

•CFL RECYCLING OPTIONS VARY ACROSS THE COUNTRY.•WAL-MART HAS KIOSKS FOR SPENT CFLS IN CALIFORNIA STORES.•THE U.S. POSTAL SERVICE IS CONSIDERING A PROGRAM WITH RECYCLING CONTAINERS AT THEIR STATIONS.•IN 2005, TRUE VALUE HARDWARE STORES IN VERMONT BEGAN TAKING BACK CUSTOMERS’ BULBS AND SHIPPING THEM BACK TO WAREHOUSES ON MERCHANDISE DELIVERING TRUCKS.
