Green Energy: Anemometer Tower
In 2002 the Whole Village community put up a anemometer to measure wind speeds on the property for a wind turbine. The system never worked properly and no one has the knowledge on how to fix it, so its been sitting up there just doing nothing. I decided that I would go take a look to see if I could figure out whats wrong with it. I had a look around, nothing around the tower seemed to be obviously wrong, so I went back down to do some research on the data logger system. The data logger is called NOMAD and is manufactured by a company called Secondwind. It is a older system so I'm having problems getting the user manual and specifications. Ill post new information as I get it




Green Energy: PV Solar Power

Whole village purchased ten used solar panels from a hospital about 6 years ago. Because no one was interested in taking the initiative to have them connected to the grid they have been sitting up in the top of the barn for the last 6 years. There have also been debates about whether or not to make the system grid tied or independent of the grid.

The first option would allow them to sell the energy back to the grid, since the new green act was signed into legislation about a week ago, they could pay off their investment in about three years (not taking into account the inefficiencies of the old solar panels). The only problem with this system is that you are still dependent on the grid for electricity. The second option would be an off grid system which would feed the solar energy into batteries to be used when needed. The main problem with this is that the solar panels wouldn't produce nearly enough electricity to run all of Green Haven. The system would have to have a larger wind turbine to supplement the solar panels. Along with this is that in the long run it isn't as Eco friendly, the batteries will only last 10-15 years at top efficiency before they need to be replaced, and all that toxic battery material ends up in the landfill. I would like to help get the process started on getting these solar panels used instead of wasting away in the barn.
