Deep Reductions in Energy Use:
Some SuggestionsA. Tamasin Sterner

Tonight We Will…►Hear about some energy-related
challenges we face globally and locally
►Ponder what we can do locally and in our own homes to work with these challenges
Problems for the US ►Gas and oil on the way out, and may be
effectively gone by 2030►The climate is changing►The economy is struggling►Energy costs are rising
Locally, PPL likely to raise costs 40% in 2010
Problems for the US ►Efficiency gains are netting zero
conservation results due to population growth, increased size of houses and connected loads.
►Electric intensity per capita has more than tripled in the US since 1960, and cutting greenhouse gas emissions requires using less electricity if earth is to remain a good place to live.
Reduced Energy Useis the key
►Even if the only problem we face is increased energy costs, many people will be in trouble, especially the most vulnerable population
A Natural Experiment: Cuba►Let’s look at what happened in Cuba
when the Soviet Union fell, the US embargo was tightened, and people were forced to adapt to very little available energy
►Watch video, 10 minutes
GapMinder Website►It took a several years for Cuba to get
back on it’s feet economically
►Show websitewww.gapminder.org
So what can you do? Reduce Use Now!
►Most everyone lives somewhere… start with your house.

“Family Controls”Behavior Change
The best investment by far!►Learn as much as you can about how you
use energy►Think before you use energy
How does this affect me? Everyone else?►Tell the truth – stay conscious►Take authentic action

Power strip Saves 0.5 kWh/day
Danny Parker, FSEC, 2006
Computer Use►Monitor accounts for about ½ the use►17” color monitor uses about 35% more energy than a 14”
color monitor ►Laser printers draw about 1/3 of print power when on
standby– 100W or so►Screen savers don’t save energy►Laptops use a small fraction of the energy that desktops use
Activate the Power Management Functions
Turn off monitor if not using > 20 min. and both CPU and monitor if not using for > 1 hour

Take Steps►If you can’t get to zero energy quickly…►Phase in your plan
►Case Study
Our House, Phase 1, 1998►High efficiency boiler►Energy Star appliances►White roof►Super insulation
Our House, Phase 2►Total lighting change-out►Ducted dehumidifier►High efficiency heat pump
Our House, Phase 3►Closed cell foam basement insulation►Home offices updated
Our House, Final Phase►Emergency Preparation
Suggested Goal
To be energy independent as a family and community. WHY?
►To protect our family and our community►Maintain, even improve our quality of life►Reduce climate change►Use our current energy resources to move
toward better energy production
How Do We Prepare?►Build on community needs, wants, values►Create broad alliances►Develop community specific strategies
and solutions►Mobilize climate champions►Make success visible – share results
