The “Half” Plan
Cut energy use and green house gas emissions in half
and
save a ton of money
![Page 2: The “Half” Plan Cut energy use and green house gas emissions in half and save a ton of money.](https://reader037.fdocuments.in/reader037/viewer/2022102818/56649d835503460f94a69342/html5/thumbnails/2.jpg)
We Will Cover …
• What’s a “Half” plan? • Energy and CO2 reduction projects
– Including some 1 year payback solar heating projects
• Results • Making your own “Half” plan

What’s the “Half” Plan?
We wanted to see if we could cut our energy use and green house gas emissions in half.
• Is it possible?
• What does it cost?
• How much money does it save?
• How hard is it?
• Lifestyle changes?

Doing Your Own “Half” PlanMaking a “Half” Plan
1. Make a BIG list of project ideas
2. Estimate energy and CO2 savings for each project
3. Prioritize Projects
4. Make it Happen!
![Page 46: The “Half” Plan Cut energy use and green house gas emissions in half and save a ton of money.](https://reader037.fdocuments.in/reader037/viewer/2022102818/56649d835503460f94a69342/html5/thumbnails/46.jpg)
Doing Your Own “Half” Plan
1) Make a BIG list of ideas
• Consider anything – Include all of your energy uses– Include conservation, solar, …
• Sources of ideas– Attached resources list
![Page 47: The “Half” Plan Cut energy use and green house gas emissions in half and save a ton of money.](https://reader037.fdocuments.in/reader037/viewer/2022102818/56649d835503460f94a69342/html5/thumbnails/47.jpg)
Sources of Project Ideas
Some good sources for ideas:• Build It Solar www.BuildItSolar
My site -- Look at the Projects page and the Half Plan pages.
• Utility audit program – these can be quite good, and some even include blower door tests to check your house for infiltration.
• Rocky Mountain Institute www.rmi.org The “Energy Briefs” papers are very good.
• Energy Star www.energystar.gov/ Lots of good information on Energy Star rated appliances as well as a wide variety of other energy efficiency subjects.
• ”The Carbon Buster’s Home Energy Handbook”, Stoyke, 2007• The EERE site www.EERE.Energy.gov/Consumer• Home Power Magazine, Mother Earth Magazine, …

Doing Your Own “Half” Plan
2) Evaluate each project for how effective it will be in reducing energy, CO2 emissions, and cost.
• This is the key to getting the best results for the money you have to spend
• Projects rates of return will vary over a very large range – this step helps you pick the good ones.
