Frank,
This is a very cool idea. CFLs definitely reduce the carbon footprint of
lighting just by being so much more efficient. I'd guess for most restaurant
or business owners, the big issue for them is cost, not the carbon or coal
savings. And you can't argue with the cost figures!
Happy New Year!

save over 5,900 pounds of coal at an electric plant and 22, 600 pounds of
carbon dioxide.
I generally don't trust these kinds of online calculators.
Does not burning 5900 lbs of coal yield an emission reduction of
22,600 lbs of carbon monoxide? No.
Lets do the back of the envelope calc.
the combustion reaction is C + O2 yields CO2
Carbon has a molecular weight of 12 and carbon dioxide
has a molecular weight of 44
One mole of carbon burned yields one mole of carbon dioxide. Thus,
burning 12 lbs of carbon yields 44 lbs of carbon dioxide.
If the 5900 lbs of coal were 100% carbon (it is not), the most CO2
emission reduction could be is 44 * 5900/12 = 21,600 lbs of CO2.
Carbon content of coal ranges from 60-80%, depending on the mine source,
so lets roll this back by at least 20%, so the final carbon monoxide
emission
reduction from not burning 5900 lbs of coal is more like 17,000 lbs of
CO2, and probably less in Michigan given the amount of western low sulfur
coal
we are presently burning with its lower carbon content compared to eastern
and southern coal (but also with a lower BTU value).
Here is a site that explores the issue in more detail.

Finally, someone needs to go and audit the facilities in China making these
CFL bulbs for their mercury management techniques and health and safety
protections.

Dear______________________________Restaurant,
I was eating in your restaurant and noticed you are not using energy efficient light bulbs. So, I am leaving this information for your attention. (I am concerned about the environment and not a salesperson.)
Thank you, ___________________________
Energy Efficiency for Restaurants
Save $$$ Hundreds per Month
Many restaurant chains in Michigan are saving hundreds of dollars a month in each facility by becoming more energy efficient. They have a cost advantage over other restaurants. Examples include: Bob Evans, Starbucks, McDonalds, Subway, Denny's and Culver's. They have switched to efficient compact fluorescent light bulbs (CFLs), T8 fluorescent and LED lighting, more efficient building and water heating, air conditioning, food preparation equipment, motion detectors, recycling and employee training.
One quick and inexpensive way to become more energy efficient is to change from incandescent light bulbs to CFLs. Many restaurants in this area are now using CFLs. Here are examples of the many benefits of CFLs:
If a restaurant changes just 20, 100W incandescent light bulbs for 20 CFLs, they will save $2,090 over two years (see http://www.newbulbintown.com/calculator/)
· CFLs last up to 10,000 hours and none will have to be changed for 2 years assuming they are turned on roughly 80 hours per week.
· In contrast, incandescent light bulbs last less than 1,000 hours and over 200 will be needed over 2 years. Changing 200 light bulbs is time consuming, costly and sometimes dangerous. (The labor cost of changing these bulbs is included in the above calculation.)
· 20 CFLs will cost about $50.00 and 200 incandescent will cost about $100.00. Lowe's and Home Depot sell 5 in a package for around $10.00. Fancier globe shaped CFLs cost around $5.00 each. The above, substantial savings are calculated using $5.00 per bulb.
· CFLs produce 90% less heat and this lowers air conditioning costs.
Besides saving over $1,000 a year in electric bills, CFLs are good for the environment. Polls have shown that most people in Michigan (including your customers) believe global warming is a very serious threat to mankind and something urgent has to be done. Using CFLs will show that your restaurant is environmentally responsible. Using the calculator above, 20 CFLs will save over 5,900 pounds of coal at an electric plant and 22, 600 pounds of carbon dioxide.
CFLs contain a small bit of mercury, but roughly 4 times less than older fluorescent tubes. Some commentators have blown this out of proportion. Should one break, there is an easy and safe procedure listed in this site. http://www.newbulbintown.com/about/cfl_break.aspx It is not a big cleanup problem.
In addition to lighting, the following Energy Star site describes the many other ways a restaurant can become more energy efficient and save considerable money plus the environment.
