Going Green

I know that green is the new black, but I like to think that we jumped on the wagon way before there was a band on it. At our house in Campbell, the garden provided more vegetables than we could ever possibly eat--meaning that our neighbors also shared in the tomatoes (usually at least three types), zucchini, yellow squash, peas and beans. This year we've planted tomatoes, beans, eggplant, peppers, zucchini, yellow squash, pumpkins and blueberries. We also have lemons, limes, strawberries, plums and fresh eggs. And tons of herbs. Let's not forget the herbs!

But while all of this is wonderful, the crowning glory is probably the solar panels that came with the house. We have a transfer box so that we can sell to PG&E whatever electricity we don't use (net metering). Every month our statement shows either how much we bought from PG&E or how much we sold to them. The latter amount is posted as a credit against our true-up, which happens every July.

I'll admit now, as I did last year, that I've become more conscious about making sure the lights are turned off and that I answer the "It's cold in here!" with "Go put on a sweater!" at least twice before relenting and turning up the heat. It's easier to do when your monthly statement comes with a bar chart showing just how much you used, sold or bought each month as compared to the last.

We got our true-up statement this week and me like-ey: Our bill for the month was 58 cents, for the year it was about 275$. Or about what we paid for one summer month in our last house. Granted, we had to leave the AC running because we were trying to sell that house, but still. I'll take it.

Solar Rules

When we moved into our house a year ago, we were really excited at the thought that, with the solar array (free with purchase!), we'd be generating most of our electricity and selling back whatever we didn't use (net metering). Now we actually look forward to the electric bill. No, really! It includes a bar chart so we can track our usage, cheer when the month's bar is short, boo and turn off more lights when it's up.

Based on our true-up statement, I'd say we've done pretty well. Actually, gloatingly well.

The way the net metering program works is that we select a payment rate at which we both buy and sell electricity. So whatever we generate and don't use, we sell to PG&E for, let's say, 10 cents per kilowatt hour. In the winter months, we buy whatever extra electricity we need at the same rate. The fun part is that, with all of this buying and selling, we actually only pay a monthly pass-though rate of $4.70. The rest is settled up at the end of the year (July, in our case), less the $4.70 per month already paid. If we owe, we send a check. If somehow we manage to have a credit, it rolls over to the next year.

Now, when we bought the house, we already knew that we totally lucked out. The general thinking is that it takes about 15 years to recoup the costs of installing a solar system (pretty cheap if it actually includes Pluto) But because our house came with a good system already installed, we immediately began to realize the savings.

Now we get to the gloating: The last couple of months at our old house, we were running the air conditioner non-stop because 1) we were selling the house and, 2) we were in the middle of a heat wave. So our electricity bills were running around $200 a month. Which would explain why I was so immensely pleased to open the true-up statement today to find that, for the entire year, our electric bill is only $173.88.

Hopefully, it won't be long before solar becomes more affordable and a viable option for more people. In the meantime, I think I'll use some of the savings to do a little economy-propping shoe shopping.
