Housing accounts for 20% of total US energy use with heating and cooling consuming a whopping 44% of residential energy use. US Energy Information Administration predicts heating oil, electricity, and natural gas will cost 2% to 10% more this winter.
Brought about by high fuel costs, single-family homes built with environmentally friendly features surged to 16% last year from 2% in 2006 according to McGraw-Hill Construction, a market research firm in New York. The cost of green homes are approximately 2% to 10% higher than a typical home.

Working with your local Utility Company
Your Energy Bill arrived and it is way to high. You can start by asking your energy provider to check your meters accuracy, but you will have to do detective work to really save money. Our local utility, PG&E, just announced another energy rate increase for 2010. You can go green and save money by following our energy saving tips. This is an overview of the many energy saving tips we have covered over the years along with links to detailed articles.
In the San Francisco Bay Area most PG&E customers have tiered energy pricing (E1 Residential Pricing plan) that starts at 12 cents, but jumps to 14, 29.4 cents, 40.4 cents and 40.4 cents as you use more power. An average home in PG&E’s territory ends up paying 29-40.4 cents/KWHr for more than half of their electricity usage. This type of pricing encourages energy conservation. Baseline quantities are set within a range specified by state law and approved by California Public Utilities Commission. This figure can vary by geographic location. Over the last 25 years, PG&E rates have increased by 4% a year. This makes saving energy much more important to reducing your energy bill.

Heating & Cooling
Weatherize your home, Caulking, weather striping, thermostats, fixing any air duct leaks are easy to do. Window treatments and Window UV Films help prevent heat loss and buildup. Set your thermostat to come on before you get home and before you wake up. Set heat to off when you are gone. Be careful when using your fireplace because they can be polluting.
Keep your furnace maintained and replace any dirty filters. Heating and cooling systems work less efficiently when air filters are dirty. Save Energy by replacing air filters with new ones. Filters costs about $10 and should be replaced serveral times a year. We’ve seen figures of less than a year for payback.
If you have allergies, be sure to get more expensive filters that capture dust and pollen.
Closing off more than 10% of vents in unused areas wastes energy because it causes your furnace to run inefficiently. The U.S. Department of Energy reports that most U.S. homes have over-sized HVAC systems, so make sure you buy the right size unit.
Seal up your light switches and outlets to prevent drafts.
Get a home energy audit to help find your problems. They use blowers that will detect areas causing heat loss.

Pool and spa pumps and heaters use the most energy in homes, making them a critical area for saving energy. Cover your pool with a vinyl cover, not a solar blanket. You’ll reduce the water evaporation, chemical usage, and lower the time you need to run the pool pump. Newer variable speed pumps run longer but at slower speeds, reducing power use.
