Planning permission has been granted for a micro hydro scheme on the River Don at Kelham Island in Sheffield, despite the fact that it will generate enough electricity to power just 20 homes per year, provided there is enough rainfall and the scheme is managed and operated with maximum efficiency. The scheme in Sheffield is not unique - many thousands of sites across the UK have been identified as 'suitable' for micro hydro development and they are being universally sold as a serious 'green' alternative, a key part of Britain's energy future and a lucrative 'community-based' investment that will help power the nation, paying sustainable dividends to those willing to part with their cash. This blog is a public resource designed to demonstrate the negative ecological impacts of 'low-head' or 'run-of-river' micro hydro schemes and asks why UK taxpayers are funding their development despite the fact that the evidence from the world over is that they do far more environmental damage than good.

Watch the film, 'Kelham Island Hydro', and ask whether what boils down to be a few kettles' worth of hydro-generated electricity is proportionate to the decimation of our little-understood and very fragile river ecosystems.

Protecting Freshwater Diversity - A Promo!

Interesting new short video emphasising just how important colonies of freshwater invertebrates are to the planet, how impoundments - e.g. weirs - affect them, and highlighting the fact that they form the most overlooked and least understood component of many of the aquatic ecosystems we think we already know. Its from the States so they've gone for cheesey blockbuster production, but the message is, nonetheless, clear:

Some very overdue updates, regarding invertebrates and their habitats closer to home, are coming soon!
