• Power Partner Program - Free Thermostat
• What it Means to Be a Power Partner
Managing peak demand helps delay the need to build new
expensive power plants. This helps keep electric rates lower. As a
Power Partner, we provide you with a free programmable thermostat
plus free installation and warranty (valued at $200-$280). You agree
to allow us to cycle off your air conditioner briefly during peak
demand -- when demand for electricity is at its highest.
• Cycling Off Keeps Electricity Demand Level
Cycling off only occurs the few days each summer when both the
demand for electricity and our load are the highest. The cycling is
similar to an air conditioner's normal cycle and is not noticeable. The
purpose of cycling is to synchronize air conditioners so they take
turns cycling on - keeping the electric demand level.
• Cycling Off Timeline
(only occurs when demand and load are highest)
June - September4:00 p.m. - 8:00 p.m. Excludes Holidays and
Weekends. Happens for No More than 10 Minutes Every Half Hour.

What can a person do today to help?
• Consider these facts...
– There are over 232 million registered vehicles in the U.S. That's almost a car per person!
– 88% of Americans drive to work.
– U.S. cars and light trucks traveled 2.7 trillion miles in 2005. That's equal to 10 million trips from the earth to
the moon.
– The average U.S. car uses 600 gallons of gasoline a year.
• So what can us average Citizens of the Earth do to curb the pollution created by cars???
Here are some 'tips for driving' to cut global warming pollution from the Environmental Defense
Fund:
– Lighten up! Carrying around an extra 100 pounds in your car reduces your fuel economy by up to two
percent. Take with you only what you need and be sure to place luggage inside instead of in the trunk or on
the roof to minimize drag and maximize your mileage.
– Take it easy. Nine out of 10 doctors and engineers agree—aggressive driving wastes fuel, not to mention
increases stress and accidents! Rapid acceleration and braking reduces gas mileage and can burn an extra
125 gallons of gas per year. Even if the person driving in front of you hasn't seen our tips list, hold your
horsepower and keep your cool.
– Keep it slow. In highway travel, exceeding the speed limit by a mere five mph results is an average fuel
economy loss of six percent. You're not on the NASCAR circuit. This is commuting, not racing.
– Don't be an American idle. Idling for more than 10 seconds uses more gas and emits more global warming
pollution than restarting your car! Also, the best way to warm up a car in winter months is to drive it. When
the temperature is below freezing, give it 30 seconds—that's all you need.
– Hot fun in the summer time. Air conditioning can decrease your fuel efficiency by as much as 12 percent in
stop-and-go traffic, so consider cracking the windows. But at high speeds, driving with the windows open
can decrease the overall efficiency of the vehicle. At higher speeds, you can use the vents to get a good air
flow. On the hottest days keep your AC on low.

• It's in the shop—car maintenance tips
– Don't be tune deaf. Keeping your engine properly tuned can save you up to 165 gallons of gas per year.
Checking spark plugs, oxygen sensors, air filters, hoses and belts are a few examples of maintenance that
can result in potential savings of over $400. (Energy Information Administration's U.S. Retail Gasoline
Prices)
– Keep up the pressure. Low tire pressure wastes over two million gallons of gasoline in the United States—
every day! Save about a tank of gas a year by keeping your tires properly inflated. And make sure to have
your tires correctly aligned to maximize fuel economy.
– Go grease lightning. Thicker-than-required oil will reduce your gas mileage because it takes more energy
to push through thick oil than it does through thinner oil. Check your owner's manual for the recommended
viscosity, and ask for it specifically when you get your oil changed.
• Failing to plan is planning to fail—other tips for everyday drivers
– Combine trips. Cutting a 20 mile trip out of your schedule each week can reduce your global warming
pollution by more than 1,200 pounds a year and save you over $100 in gas expenses.
– Share a ride. Carpool and use public transportation when possible. If you share rides and use other means
to get to work, you'll save yourself money, reduce congestion on the roads and cut your global warming
pollution.
– Just park it. And keep it there. If you’re going to several stores in the same strip mall, don’t move your car.
Walk.
– Gotta wear shades. In summer, park in the shade. Use windshield shades to keep summer heat from
baking your car and to help keep frost away in the winter.
– Move your feet. Walk, ride a bike or take the train when your car isn’t needed.
– Avoid the rush. Plan trips during off hours when fewer cars are clogging the roads.
– Wholesale sales. Buy in bulk when shopping, instead of making frequent smaller trips.
– Spread the word. Be an ambassador for the Earth by sharing these tips with family and friends.
