Estream, a portable water turbine to power electronic devices

Mila Luleva — Tue, 16 Aug 2016 20:58:28 +0000

Estream is the latest technology that provides portable power for electronic devices. It is hydro-turbine that uses the force of flowing river streams. Staying connected at all times is now more important than ever. Only a decade ago a lack of a mobile phone or reception (or Wi-Fi for this matter) was not really a big deal. […]

Hydroelectric Dams Disturbing to Wildlife, Study Finds

Courtney Lepping — Tue, 31 May 2016 18:42:17 +0000

Hydroelectric dams were recently recognized to threaten a number of species on reservoir islands. Popular around the world, hydroelectric dams were discovered to have a reduction in animal and plant life after flooding. The dams have been said to protect species from hunting and deforestation, but research has shown a disturbing trend. After careful inspection […]

Japanese Consumers to Gain More Renewable Energy Options by 2020

Annika Tostengard — Tue, 01 Dec 2015 20:57:30 +0000

Tokyo has been picked as the location of the 2020 Summer Olympics, and the city hopes to showcase its commitment to renewable energy as part of the fanfare. If Tokyo’s plans move ahead on schedule, Japanese consumers will get 20% of their electricity from renewable sources including solar, hydrogen fuel cells, and hydropower. As the […]

US Can Run Entirely on Renewables by 2050, Scientists Say

Mila Luleva — Wed, 10 Jun 2015 20:17:44 +0000

If all states make full use of the best available renewable sources, the US can run entirely on renewable energy by 2050. A study conducted by a team of scientists from Stanford University, established that the U.S. can go 100% renewable if everything- homes, cars, factories, etc., runs on electricity. And before anyone comments that it is […]

New Dutch Power Plant to Produce Energy From Sea Water

Mila Luleva — Thu, 27 Nov 2014 08:22:34 +0000

The latest addition to the growing renewable energy family comes from researchers from the Netherlands. They developed a system, which produces electricity using the difference in salt content between sea and fresh water. This new technology will go into first testing next week, as the first test facility, called Blue Energy, will open its doors. […]

World’s Largest Floating Solar Power Plant Under Construction in Southern India

Mila Luleva — Fri, 04 Jul 2014 17:56:20 +0000

Over the past few years, the renewable energy sector, and more precisely solar, has received a huge boost. Developments in manufacturing of panels have resulted in a major drop of prices, making it extremely hard for wind-, hydro-, wave- power and all other renewables to keep up. Of course, this has not gone unnoticed by […]

Toilet Hydropower: Scientists Developing New Source of Energy

Mila Luleva — Tue, 22 Apr 2014 19:06:12 +0000

With all the horrendous warnings that climatologists are issuing, urging us to stop wasting fresh water, everyone with a clear mind should be looking into ways to save the precious resource. There are many options to recycle and reuse water from our taps and baths, without it even leaving the household, but a team of […]

World Bank Takes Stronger Stand Against Coal-Fired Power Plants

Leigh Hutchens — Thu, 18 Jul 2013 01:51:18 +0000

On Tuesday, the board of the World Bank decided that it will halt the financing of coal-fired power plants and will allow it only under rare circumstances. The only funding for coal-fired power plants the World Bank will allow is to countries that have no other feasible alternatives to coal. The organization wants to ensure […]

Loss in Rainforest Could Lead to Drop of Hydropower Generation

Mila Luleva — Tue, 14 May 2013 19:00:31 +0000

A study published in the Proceedings of the National Academy of Science earlier this week revealed that deforestation in tropical regions will lead to a reduction in hydroenergy output. Scientists explain that rainforests, especially in the Amazon basin, Central Africa and Indonesia, are not only responsible for controlling the carbon cycle, but they also play […]

FloDrive Turbine – 1kW Hydroelectric Generator to Power Homes in Developing Countries

Mike Sandru — Thu, 08 Jul 2010 17:13:03 +0000

Students at Cambridge University have recently created a portable hydroelectric generator that is able to supply up to 1 kW of electricity when installed in free-flowing rivers. Called the “FloDrive Turbine”, this generator could be used to power homes in developing countries, being very easy to install and needing no special equipment or infrastructure. According […]

Hydrokinetic Power Does Not Affect Fish Populations

Cristi — Tue, 12 Jan 2010 20:11:26 +0000

We all need electricity for powering different stuff in our home, to make our lives more pleasant. But if the electricity is produced using green sources it's even better. One of the most used types of energy up to now was hydropower, but this one involves the construction of dams, weirs or other structures that could affect fish.
