Big hydropower has huge unintended consequences

Big hydropower dams are not only hugely destructive while being built, they have disastrous environmental consequences after completion. Scientific American details the Three Gorges Dam Disaster in China in a 2008 article citing problems like less rain and more droughts, increased chance of earthquakes and landslides, and potential for spreading of disease. The vast weight […]

Huge hydro power dams change the weather around them

Guri, a ginormous hydro project in Venezuela, ended up producing far less power than anticipated. Bruce Krasting asked a friend at the World Bank what happened. BK: Where’s the juice at Guri? WB: Bad question to ask. The rainfall that historically fed the region has changed its pattern and annual flow. There are some who […]

Why we need stored power for electricity

Bonneville Power may have to shut down wind turbines because too much power is being produced by wind and hydro. If they let excess water flow over spillways this could raise nitrogen levels in the water, harming fish. So instead, they will turn off the wind turbines. If we had a grid that allowed large […]

Unconventional hydro power

Renewable Energy World has a long, detailed article and podcast on unconventional hydro power, focusing on wave and tidal power.

Portable hydro turbine for small electronics

Backpackers will love this easy way recharge a GPS. Daniel Hull, an Australian industrial designer based in Melbourne, has designed a portable hydro turbine with the aim of providing cheap renewable energy using water.

Backpack Power Plant. Portable hydro power

The Bourne Energy BBP-2 weighs 25 lbs, fits in a backpack, is entirely self-contained, and outputs up to 600W of energy from river current with no heat or emissions. They can be daisy-chained in large arrays as can the BBP-1 (pictured) Tip: Inhabitat

Retrofitting dams to produce energy

Only 3% of US dams produce power. American Municipal Power in Ohio thinks that’s a waste and will retrofit five dams to produce 350 MW, a simple, great idea that in retrospect seems so obvious you wonder wht it wasn’t done before.
