Globally, hydropower contributes approximately 17% of all electricity generated using renewable resources.

The British Hydro Association (BHA) represents the industry in the UK and provides valuable guidance to facilitate the growth of micro-hydro (http://www.british-hydro.org/index.html).  In addition, the recently formed British Hydropower Association supports tradesmen in the micro-hydro industry and provides an additional source of guidance.  The BHA provides an excellent guide to researching a micro-hydro project.
