1. Renewable Energy

2. Photovoltaics At $3 per watt installed 10 year payback (plus or minus) DOE estimates PV takes off at $1 per watt Al can approach to Solar Misnomers: More energy to produce than generate EROI of 6.5 (Coal is 70, Diesel is 7) Environmentally beneficial 48 g-CO2 kWh-1 (Coal 820 g-CO2 kWh-1) Cell lifetime of 20 years-replace system Manufacture guarantee for 20 years Can produce for longer than 20 years 0.93% degradation per year

3. Geothermal Geothermal uses earth as a temperature source (winter) / sink (summer) Earth at 20 ft is 50-60 degrees. Heating and cooling is relatively inexpensive Geothermal is site specific Want to hit water table-improves heat transfer Payback Installed costs range $10K to $25K Savings $400 to $1500 per year Retro fitting is more expensive than new build Approximately 10 year payback Reliable low to no maintenance

4. Conservation Lighting IncandescentCFLLED Life (hrs)120010,00050,000 Cost$1$3.95$10 Op. cost (50k hrs)$300$70$50 Required Bulbs (50K hr) 4251 Total Cost$342$89.75$60 LED bulbs are/have become competitive LEDs 30% reduction in energy Decreased maintenance Don’t use light sockets to heat your house

5. Conservation Average savings 10-12% on heating 15% on cooling Total of $131 to $145 per year Nest cost $250 Payback 2-3 years Programmable thermostats Work well if they are programmed Smart Thermostats

6. Conservation 2 billion gallons of wasted fuel every year 10 times the amount of energy that is produced through solar power in the US annually 25% of all vehicles on the road are running with underinflated tires Besides safety, it saves you money Inflate your Tires!
