Here are two things that nobody wants to see increase. 00:00:00
Your power bill and pollution. 00:00:08
Boo! 00:00:10
We're going to show you a small step you can take that can turn these arrows the other 00:00:11
way. 00:00:15
Yay! 00:00:16
We're focused on your friendly household light bulb, the incandescent kind. 00:00:18
The chances are there is one within a few feet of you right now. 00:00:21
Go ahead, look around. 00:00:24
That light bulb is not cool anymore. 00:00:26
It's the VCR of light bulbs and it's quickly becoming obsolete, and for good reason. 00:00:29
It's being replaced by a new kind of bulb. 00:00:33
It's called a compact fluorescent, or CFL, and it's an easy way for you to make a big 00:00:36
difference. 00:00:40
Here are two reasons why. 00:00:41
The real problem is coal, which is used to create over 50% of our electricity. 00:00:42
When you turn on a light bulb, most of the electricity that powers that bulb comes from 00:00:47
burning coal. 00:00:51
When it's burned in power plants, CO2 and other pollution is released into the air. 00:00:53
More burning coal equals more pollution. 00:00:57
Not cool at all. 00:01:00
If that wasn't enough, coal also costs money. 00:01:01
The more you burn for electricity, the higher your power bill. 00:01:04
So the ultimate goal is to burn less coal by using less electricity. 00:01:07
Here's why new light bulbs matter. 00:01:11
If you replace that old light bulb with a new CFL, you can save money and help prevent 00:01:14
pollution at the same time. 00:01:18
Consider these three big points. 00:01:20
First, let's say you have a lamp in your house that you leave on for one full year, 00:01:22
You start with a 750 hour incandescent bulb. 00:01:27
That lasts about a month. 00:01:31
This means that over a year, you'll use about 12 bulbs for the lamp. 00:01:32
At 60 cents a bulb, that's about $7.20. 00:01:36
Now compare that to a single CFL that costs about $4. 00:01:40
A CFL in the exact same lamp will last 10,000 hours. 00:01:43
That's about the same as 13 regular light bulbs. 00:01:47
This should be clear. 00:01:50
Less hassle, less money. 00:01:51
But the last two points are the big ones. 00:01:53
Lighting accounts for, on average, about $20 of a $100 monthly power bill. 00:01:55
And CFLs use one quarter of the power compared to an incandescent bulb. 00:02:01
This means that using CFLs can lower a $100 power bill to $85 a month. 00:02:05
That's cool. 00:02:11
And finally, switching to CFLs can prevent hundreds of pounds of CO2 pollution each year. 00:02:12
That pollution is a cause of global warming. 00:02:17
So you can see the point. 00:02:19
CFLs are simply a smarter way to light your home. 00:02:21
If you're still not convinced, note that these aren't the buzzing blue tube lights 00:02:25
from the kitchen of your past. 00:02:28
CFLs have come a long way lately. 00:02:30
Popular Mechanics did a blinded study with new CFLs and participants preferred the CFL 00:02:32
light compared to incandescent bulbs. 00:02:37
And they fit in the same fixtures. 00:02:39
The question to ask is, why not switch to CFLs? 00:02:41
The next time you're at the store, pick up a 4-pack of CFLs and replace the bulbs that 00:02:44
are on the most. 00:02:48
Maybe the porch lights. 00:02:49
Then ask your friends, why haven't you switched? 00:02:51
Are you still watching movies with a VCR? 00:02:53
