Other Power + Costs

I came across this really useful website on alternative energy. It looks like it’s been gathering dust  and it’s design is somewhat outdated but it’s information seems timeless. Whether you want to go about doing it yourself or to use commercial solutions – their website is a great resource of information – check out Other Power.

Through their website I found two other useful links:

  • One is the US Department of Energy – though the information is presented a USA context – some of it is global and useful. Specifically I found the area on eletrciticy to have useful overview explanations of eletricity generating systems and their components.
  • The other is Bergey – a manufaturer of products and systems. Specifically their Packages pages provides tangible understanding of (a) the potentially high costs of commercial systems and (b) the relative costs of components that are needed to put together an entire working system.

Here is an example of a system that delivers: 400 – 1,500 Kilowatt-hours (kWh’s) per month (depending on wind resource), 24 hours to over a week of back-up power (depending on load and wind).

7.5 kW BWC Excel-R/48 w/VCS-10 $26,870
100ft. guyded latice tower kit $14,145
Tower wiring kit $1,615
DC Power Center, 9 circuit $850
84 kWh, 5 String, Battery Bank $15,000
7.2 kW Inverter system $6,676
Total costs $65,156

The most expensive elements are the turbine itself, the tower and the batteries. The price of the batteries was informative to me because they are needed regardless of how you generate electricity (wind, solar, hydro… ).
