ReGeneration Roadtrip: Can't fight the tides Verdant Power shows it's got the RITE stuff	Sarah van Schagen	09 Oct 2008	Gristmill
This is a guest post by my travel partner, Todd Dwyer, head blogger for Dell's ReGeneration.org. ----- Four times a day, without fail, New York City's East River will change directions. It's been doing that for ages and will continue to do so long after we are gone. The tides are a constant, powerful force, and the folks at Verdant Power are on Roosevelt Island experimenting with a way to draw energy from them without impeding their flow or harming ...

Do the Congo? Gigantic hydropower dam planned for Congo River		21 Apr 2008	News
Posted at 2:44 PM on 21 Apr 2008 Some of the world's largest banks and construction firms gathered with seven African governments Monday to chat about plans for an $80 billion hydroelectric dam on the Congo River. The proposed Grand Inga dam could generate twice the electricity of China's controversial Three Gorges Dam and greatly increase the amount of cheap and clean power currently available in Africa, according to supporters. &qu ...

Small hydro, big potential 'Run of river' projects set for a boom?	Erik Hoffner	28 Mar 2008	Gristmill
When I bought my house, I didn't realize that the stream that travels its acres is perennial and spring-fed ... which seemed like the perfect scenario for a microhydro generator. These units make a lot of power all day and night, unlike solar and (usually) wind. It works by siphoning off a portion of water to run through a pipe, then through a generator, and then back into the creek. Voilà! So I did the measurements and found 140 gallons per minute, which is about eno ...

Patagonia: It's a dam ... threat Some of world's purest water and pristine ecosystems under threat	Gar Lipow	15 Mar 2008	Gristmill
International Rivers is fighting to preserve biodiversity against the large companies that want to dam this river: The Pascua River, in Chilean Patagonia, is one of the most pristine and unknown regions on the planet. Why? For one, it is extremely difficult to even get there. Secondly, once you actually see the river, doing anything other than standing with your mouth open and hands over your ears is virtually impossible. This is a rip-roaring, roller-coaster of a riv ...

Natural gas from dams Dam it all	Gar Lipow	08 Jun 2007	Gristmill
Tucuruí, Brazil's second largest dam has many times the GHG emissions of a natural gas plant of the same capacity -- though there is fierce argument over whether that output substantially exceeds what a natural watercourse would produce. (The emissions are due to methane from trapped organic matter in the dam.) There is now a proposal to tap that methane to run gas turbines and produce electricity, reducing the emissions many times, since CO2 from burning the methane ha ...

Let's kill this meme Why we gotta knock solar?	John McGrath	05 Jun 2007	Gristmill
Can we please, once and for all, stop decrying solar energy for being too area-intensive? See, for example, the oft-cited statistic that to power its economy, the U.S. would need "10 billion meters, squared, of land." America isn't exactly short on square meters, and awfully sunny ones at that. But 10 billion square meters sounds a lot bigger than it really is. 10,000 square kilometers (100km x 100km) form a square you could drive around entirely, at legal ...

Profit and Laos Big dam project in Laos aims to minimize environmental and social damage A controversial hydropower dam under construction in Laos will serve as a test case for whether a large dam can be built without trampling too heavily on the natural world and human rights.

Dam Hydropower a major greenhouse-gas producer, researchers say		25 Feb 2005	Daily Grist
Dam Hydropower a major greenhouse-gas producer, researchers say Although hydroelectric power is often heralded as a green alternative to fossil fuels like coal, scientists now say that in terms of greenhouse-gas production, hydro projects may be just as damning. Ahem. New research reveals that the initial flooding involved in creating hydroelectric dams releases large amounts of carbon from plants that are kille ...

A Blow to the Solar Plexus		09 Dec 2002	Daily Grist
A Blow to the Solar Plexus Renewable energy use in the U.S. dropped sharply in 2001, according to a new report by the Department of Energy. Much of that decline stems from a drought that cut hydroelectric power generation by 23 percent, but the DOE's Energy Information Administration also found that in 2001, solar equipment was retired faster than it was replaced. The bulk of ...
