On-site power generation at Sierra Nevada Brewery

This is an interesting site whatever beer you drink, or even if you do not drink anything. These guys take reduction of their carbon footprint seriously. And, by the way the beer and food available at the pub is good too if you are ever in the Chico, Ca area.

And here is the web page Chico Electric which installed the solar array at Sierra Nevada Brewery.

They talk about this install, and one at Butte College.

Are we in the long emergency?

I have been reading "The Long Emergency" by James Howard Kunstler. The basic premise is that the one constant in the world’s industrial expansion and all life as we currently know it (at least in the industrialized power countries) was possible only because it happened during the times of cheap oil. We are currently near or just past the maximum world production for oil, and there is only down-hill to go from here. Because production of cheap oil is past its maximum now, and demand is still there, we are rapidly going to be in dire straits. Look elsewhere for reviews. His prediction seems pretty cut and dried. We are doomed to be in the decline and he holds little hope for us to get out of the emergency in any form that is close to life as we currently know it.

He does make a few good points. It is true that there is a limited supply of finite resources. Maybe this means we should be going much more towards some other energy source than we have been in recent years. He does not think we should rely on letting technology come up with a solution, because any alternative that technology brings to light will require cheap oil to build to a point that it becomes a feasible alternative. And we no longer have the cheap oil.

Maybe it is a good thing that oil has jumped a bit in price recently, whatever the reasons except for oil company price fixing or speculators trying to manipulate the markets. Maybe we need the wakeup call that life as we know it needs to change. We need to start conserving a bit, and we need to institute some way to get away from oil, whoever is producing it. And we need to stick to that plan.

When Jimmy Carter was elected President he installed solar panels on the White House roof. At the time this was very experimental and expensive and few regular people could afford to even consider a move like this. He did it as an example of the spirit we need to adopt in order to get out of a potential energy shortfall. When the next president took over, the first energy related step he took was to remove the solar panels. If we had proceeded back in President Carter’s days and maintained that energy awareness, maybe Mr. Kunstler could have written a bit less scary book. If we start working in a concerted effort now, maybe we can get out of the emergency more or less intact.

True-up Electric billing for 2011

Our true-up electricity bill for the year was $46.14 for electricity used that we did not create ourselves. Add in the monthly charges that are administrative in nature, and it goes up to $110. This is still pretty good. In 2008, our total cost was $125.00 with administrative cost added in. We could easily be using $100.00 per month in electricity at least in the summer months.

updates

Gas has gone up nearly fifty cents in a month here. Most recent price for regular was 3.869 with a three cent a gallon Safeway member discount. My current mileage in the Prius is in the mid 40’s which is OK for winter, and the fact that my trip length is very low now that I no longer have to drive to work. Last tank or so, I did a few longer trips and the mileage was back into the high 40 to low 50 range, still good for a car that is nearing seven years old- and a hybrid at that. I still would rather drive this Prius than most any other car out there. Well, maybe the new 2010 Prius or the new Chevy Volt.

Our solar panels are still putting out OK. This last year we had major higher daily use of electricity than in other years, but we are still under $100.00 for the year. Not too bad considering we have not been able to conserve as much as in previous years.

Cleaning Solar panels

Things are changing pretty fast in solar as far as cleaning goes. A couple of years ago when I searched for information about cleaning solar panels, it looked like no one had anything to say. Now it is different. Not only do you have information suggesting dirty panels can cost at least 10% loss in production, but there are cleaning services listed in some communities, and there are automated cleaning systems.


This is a system that includes a sprayer for each panel, filters and soap dispensers. It can be set to rinse between wash cycles. I am not suggesting this is the answer. It is hard for me to see just how effective this system would be in my area where it takes a bit of scrubbing to get the dirt off. But if you are in a fairly low dirt area, it might be fine for you.

Solar Update

As if 06/16/2010 we have now past 16,700 KWh of production on our little solar array. Presently we are producing a bit over 10 KWh a day, with most of this being produced from noon to six. That means we get reimbursed at the higher rate for E7 Time of Use metering. That is a good thing. We are a bit off recently due to cooler cloudy conditions the end of May and in early June. We also have a contractor working, so our use is a bit up overall.

Unscheduled Solar panel maintenance

Actually, there is so little maintenance for these things. You may think though that you can just set up and let it go forever. That may be true, but you should check thigs out from time to time.

Here, in a quick check earlier today I realized that a tree branch had grown out over one section of the panels since I had looked a bit ago. It was shading the panels form around noon on. True, it was only a small portion of our total panel area, but that can add up to a big problem over the long haul. These things are wired in series, so a small area of shade can degrade production of the entire system.

I cut a few branches, and our output went from around 1100 watts to 1400 watts, and higher. That difference can add up to more than an extra kilowatt hour over the days production.
