Path to your Energy Savings Existing Residential and Small Commercial

1 Goals of this Webinar Provide the tools and inform you of the steps you should take before and after installing solar to maximize your investment and reduce you carbon footprint.

2 Agenda PG&E –Delivery Mix –Integrated Approach The Full Energy Picture Before Going Solar –Energy Conservation –Energy Efficiency Going Solar After Solar Resources

3 PG&E’s 2008 Electric Delivery Mix on average over 50% of the energy delivered comes from sources that emit almost no carbon dioxide Coal 2% Natural Gas 44% Other 1% Nuclear 22% Large Hydro 17% Renewable 14% Biomass and waste 4% Geothermal 4% Small hydroelectric 4% Wind 2% Solar <1% Note: Delivery mix includes all of PG&E’s owned generation plus all of PG&E’s power purchases.

4 PG&E’s Projected 2009 Electric Delivery Mix

5 We’re committed to Energy Efficiency PG&E has saved more than 155 million MWh and 12.5 billion therms from installed energy efficiency measures, which is the equivalent of powering over 23.5 million homes with electricity and heating 25 million homes with natural gas

6 PG&E’s Integrated Approach Reduce Energy Use Renewable Power Supply Neutralize Energy Use Energy Efficiency Solar & Wind Climate Smart

7 1.Energy Conservation (No Cost) -Changing usage patterns to reduce energy consumption 2.Energy Efficiency (Low Cost) -Using less energy without changing patterns 3.Energy from Renewable’s (Investment) -Energy generated from natural resources (Solar, Wind, etc) 4.Carbon Offsets -Programs that allow individuals to reduce their impact on climate change The Full Energy Picture: Loading Order

8 Why Energy Efficiency Before Solar? Bigger “Bang for your Buck” –Less usage = smaller energy bills –Cheap, easy, and less destructive to implement than other methods of energy –Less usage  smaller solar system needed  lower cost Energy Audit Required to Participate in CSI Program –Educate yourself and your customers Analyze usage Learn what to do Contractor –Competitive advantage

Before Solar

10 Energy Audit: SmartEnergy ™ Analyzer Create a profile of your home and appliances Identify how much energy and money you can save Create a customized energy plan Take an Energy Efficiency Audit

11 Step 1. Conservation Practices (No-Cost) Keep your thermostat at 68 degrees in the winter and 78 degrees in the summer (health permitting) Adjust thermostat up/down when you leave home or go to bed Lower your water heater’s thermostat to 120 degrees F Only run full dishwashers and loads of laundry Turn off the water when brushing teeth, washing dishes, etc. Take shorter showers

12 Step 1 (con’t). Conservation Practices (Low Cost) Install faucet aerators, ultra-low flow toilets and showerheads Install irrigation controllers or, even better, drought- tolerant landscaping

13 Step 2. Strive For High Efficiency (Low-Cost) Replace regular light bulbs with Compact Fluorescent Lamps (CFLs) –CFLs lasts up to 10 times longer and use up to 75% less energy than regular bulbs Look for the PG&E sticker and save! –Dispose of burned out bulbs properly by visiting Earth911.org to find a recycling facility

14 Step 3. Strive For Higher Efficiency (Investment) Buy high efficiency appliances (i.e., clothes washers, dishwashers, water heaters) –These appliances use 10% to 50% less energy than standard appliances –Look for the ENERGY STAR  Weatherize your home –Insulate your attic and your walls We offer Rebates!

18 Step 4: Go Solar Do your research: –Roof conditions –Shading and direction of roof –Obtain bids from a minimum of 3 contractors –How much usage to be offset (size of system)

19 Step 4 (con’t). Go Solar Reduce Costs –California Solar Initiative 10 year program ( ) Must be in Investor Owned Utility (IOU) territory Residential Retrofit, Non-Residential retrofit/new construction –Federal Tax Credit 30% of net cost Extended through 2016 –Net Energy Metering Meter keeps track of debits/credits “Buy and sell” at the going rate Cannot make a profit

After Solar

21 E-6 Time Periods Time of Use Maximize your Rate Schedule

22 Buying low and selling high adds value. Use Credit Credit Time of Use Rates Maximize your Rate Schedule Use Credit

23 Continue Conservation and Energy Efficiency Practices Maximize your systems production Solar is not an excuse to neglect conservation and efficiency Environmentally friendly Consider your Carbon Footprint Regular maintenance on your system
