The following two charts show the “Small & Micro Hydropower Newsletter” Community as of May 6 2009 and March 17 2009. Our Small & Micro Hydropower Demographic population has changed only slightly since we started collecting data. Note the charts are normalized to the total responding population which represents about 50% of our overall membership. I think you can see we are still a diverse Hydropower group that share a common interest in Small & Micro Hydropower generating systems.
Notice that Small & Micro Hydro Interest have swapped places from what we showed in our original Hydropower Community update newsletter. Small Hydro vs. Micro Hydro Interest percentages are within a few points of each other and I suspect there is no significant difference in the voting here. It sounds like we are right on with the Newsletter target. Thanks to those who filled out the survey. You can see our original demographic results by visiting: Original Small & Micro Hydro Community Survey.
The following data shows the Small & Micro Hydroelectric Community as of a little over a month ago. Only subtle changes within about 1-3% experimental error.
Some of you have correctly mentioned that there are significant differences in Small & Micro Hydropower systems with regard to physical plant size and capital $ investments, ROI, regulations, etc.
While this general observation is true the actual fluid mechanics and electrical physics involved are mostly the same, so we will continue to address both populations here and in the newsletter. As we encounter major differences we will try and point them out so you can be aware. If you see Small or Micro Hydro issues that I forgot to point out please share them with your comments on that SmallHydro.com Blog post. The other Small Hydro Community plots are over on the www.DoradoVista.com site.
