Results Are In!

Tuesday, September 8th, 2009

Hi Guys,
I Just got my utility bill for the first month of full solar operation.  Gas consumption was 0.07 therms / day ($0.29), as compared to a summer monthly average of approximately 0.75 therms/day ($1.40).  Why, you might ask, did the cost not go down by 10X like the usage?  There’s a flat monthly customer charge of $5.30 for service, which accounted for the bulk of our $8.12 gas bill.  As predicted, virtually all the gas we were using in the summer was for heating hot water.

It’s not quite the whole story, since we were away for 10 days on vacation.  We probably would have used 0.10 therms/day.  But it still looks like we’ll save on average a buck a day, as long as the sun keeps shining.

Other interesting facts: average family usage in the summer in Palo Alto is 30 therms / month.  So we started at about 75% of normal usage.  Then again, we’re about 75% of the size of the average family.  A therm, in case you’re wondering, is 100,000 BTU and will heat 160 gallons of water to approximately 130 degrees.  Amazing what you can learn from your utility bill.

The system is working perfectly. Hope you’re installing a bunch of systems.  I was walking around midtown Palo Alto and looking at the rows of nearly-identical ranch houses with their unshaded, south-facing, 20 degree asphalt shingle roofs and thinking “That’s a good one…and that one…that one too…”  Now I’m obsessed!

See you,
John S.

Why It’s Time to Change

Monday, September 7th, 2009

Take a look around. No really, just look around. Maybe half of the objects around you run on some form of energy. It’s vital to our entire lifestyle. Of course, centuries ago, we were not so dependent on energy. But times have changed, and we must be able to change with them. We can no longer deny this new dependence on energy. What would we do without electricity for computers? Without fuel for cars? Without refrigerators?

Energy doesn’t come out of thin air. We would like to think that energy simply comes out of the electrical outlet. We would like to think that “behind those three small holes in the wall there is a huge, unlimited amount of energy bubbling around.” But it’s not true. It’s not there. And anyway, energy doesn’t even bubble.

As every year passes by, our global needs for energy increase. Our energy sources, however, are not growing as well. Time is running out. Every single day, gasoline is used and pollutes the atmosphere. Every single hour, a factory throws carbon into the air. Every second, pollution is destroying the only planet we have to live on. Our problem is given to us: We are dependent on energy. Our solution, however, had to be found.

The problem increases day by day. The longer we wait, the harder it will be to stop this growing problem. We can no longer wait for someone else to take a step forward. We have to be the ones to take a risk. Why not? Who says that we are too young or too old to change the world? We can be the ones to lead the rest of the world out of its energy problem. There is a solution out there. It’s called solar water heating.

Solar water heating is the most environmentally impactful investment you can make. Natural gas litters the environment with CO2, and according to PG&E, solar water heating can save more natural gas than any other home improvement. If you could save energy, money, and the environment at the same time, you’d do it. Now ask yourself…Why not? VS.
