$1 per watt of Solar Energy

In September the University of Colorado announced that the manufacturing of low-cost, high efficiency solar panels is nearing mass production. The technology is patented by Professor W.S. Sampath, a mechanical engineering professor at Colorado State.

The process should make the total cost to consumers as low at $2 per watt,including instillation cost, which is half of what the current cost of solar panels. Plus you can take the panels off-grid with you. They do not require plug into the grid to work, though being high efficiency, if your state allows rolling back your electric meter, you may want to.

The process to build these panels is to be fully automated with continuous production. With less then 2% of the materials used in that production needing to be recycled. These cadmium telluride panels need 100% less semiconductor material then the high-cost crystalline silicone panels.

According to AVA Solar website these panels should be in large scale production by 2009.

With state and federal incentives this could significantly lower the initial outlay homeowners would have to pay to be self-sufficient in their energy. The only stumbling block is will Fort Collins, Co approve the project to move forward.

Fort Collins, a city that takes pride in being green, is worried about the cadmium, a hazardous metal that has been linked to cancer, that is used in the process of making these panels. This also highlights that while going off-grid/green is the desire, there will be decisions that still need to be made based on our old friends money and global responsibility. We will continue to follow AVA Solar and let you know when their panels hit the market.

Architects Designs Going Green

A survey done by Autodesk and the American Institue of Architects (AIA) showed that by 2012 90% of their architects expect to incorporate some sustainable elements in their designs. This is said to be due to client demand, not government regulation. This shows that if we as consumers demand better options in building/remodeling our homes, we will get it. 88% of those who responded to the survey also stated they are or have had training on focused on green building.

This is definitely a plus or those of us who need to build or remodel our dream off-grid home,as finding a qualified architect versed in sustainable building will be easier. No one said having a off-grid home means you have to sacrifice your needs, just fulfill them with renewable sources.

By increasing our demand we are lowering the cost. Just look at the cost of solar modules in 1982 it was about $27/per watt peak now down to $4/per watt peak. So that in 2003 a residential solar system cost about $8,00- $12,00 per kilowatt peak installed. (according to solarbuzz). If we can do this in design and solar, then all alternative energy sources will be effected as demand for them go up. Each renewable energy source works better for different environments. In South Dakota wind is the power of choice, in California it’s solar, while in Indiana biomass and geothermal are being highlighted.

So each renewable source has someplace/community that is interested in it more then others because of the environment inherit there. Making decisions not only on what’s popular now, but works best in your own backyard is important. Solar seems to be the forerunner right now, but that doesn’t make it right for you. Do research about what is being used in your location, and then look to other locations with an environment close to yours, doing the first round of research will save you not only money later, but you’ll be able to evaluate which experts can truly help you.

Going off-grid/green isn’t something that should be done without research and a desire to do it. It’s fraught with errors to be made, lessons to be learned, money to be lost, and schedules to be lengthened. The only way to make the learning curve go in your direction is to learn as much as you can before embarking on this adventure. If you have already embarked, then keep learning, and learn from as many resources as you can from mainstream to fringe, or even completely off topic, because you never know where the next big idea will come from.

Blue Crabs Leaving Maryland Tables?

I know how does that work with getting people off-grid? Well look at it as a cautionary tale of what not being self-sufficient and responsible in our resource usage of running a home can lead to. Yes, I know most of the dead zones in the Chesapeake Bay are attirbuted to commercial, but let’s just go with the flow on this one. I’m from Maryland and not being able to have crabs because the Bay isn’t being cleaned up like we were promised is a life changing event here.

Yes, I know we are not to that yet but with only a third of the population of the early ’90’s when the population really started to drop, it’s not just a nightmare. Since harvesting is less the half, 48.9 million pounds,of what it was at its peak, over 100 million pounds, over fishing being a main cause doesn’t really fit. Since sturgeon and shod have already disappeared with oysters hot on their tale, it’s starting to look like our’s favorite crustasian thinking about being next. We have started programs to oyster farm, but you can’t do that with the crab, so the only way to fix it is to get rid of the dead zones still in the bay.

While we may not see the extinction of the crab, we may see the extinction to the luxury of eating them if the population keeps dropping. With that we can now add waterman to the extinction list here in Maryland. I have heard of some stories of waterman turning to oyster framers, but that won’t work for them all and it still doesn’t clean up our Bay.

For something that has been in the works for so long and due to be finished by 2010, it’s amazing that the citizens of this state are not being more alarmed that the one thing the both sides of the bay have in common is still damaged and in some parts dying. The signs are up letting people know where the watersheds are, we have been told for over 10 years what not to do to make it worse, our children learn about it from elementary school, yet it is still able to be ignored.

If our government says that because they don’t have the billions of dollars needed to clean up the farmlands/septic systems, upgarde sewage plants, etc. Then maybe us as individuals need to stop just listening to the news stories, looking at the signs, and really hear and see them. We as a population are just as responsible for what we let run through our fields, roads, and waterways. If we want to live in a state that says it wants to be clean and healthy maybe we need to show the government and our neighbors what that looks like. You wouldn’t tell a child they need to change while you …
