Don't move a mussel: Small freshwater biofoulers carry a big price tag
Anyone that has spent time at a seaside pier has witnessed the destruction barnacles wreak on boat hulls. But biofouling animals are not limited to marine environments. A new paper published in the journal ...
Policy issues plague hydropower as wind power backup
Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to Penn State researchers.
A storage power plant on the seabed
Norwegian research scientists will contribute to realising the concept of storing electricity at the bottom of the sea. The energy will be stored with the help of high water pressure.
Explainer: What is hydroelectricity?
Hydroelectricity is an established power-generation technology with over 100 years of commercial operation. Hydroelectricity is produced when moving water rotates a turbine shaft; this movement is converte ...
Novel inline hydropower system for power generation from water pipelines
Generating electricity from water is not a new thing. Hydro power stations have already sprung up across the world in China, United States and Canada. However, scientists will not stop exploring advanced technologies for ...
Americans use more efficient and renewable energy technologies
(Phys.org)—Americans used less energy in 2011 than in the previous year due mainly to a shift to higher-efficiency energy technologies in the transportation and residential sectors. Meanwhile, less coal ...
Virtual power plants for renewable energies
Siemens recently put two virtual power plants into operation. Virtual power plants are networks of several small power stations that are run like a single system. One of the new virtual power plants enables ...
Work on Africa's biggest wind farm in Kenya to begin
The construction of what is to become Africa's biggest wind farm will start by June in an arid region of northern Kenya, the project's officials said on Saturday.
Quake-prone Japan looks at geothermal energy
The forces that make Japan one of the world's most quake-prone and volcanic countries, and sparked a nuclear disaster, could become part of its long-term energy solution, experts say.
Small is beautiful in hydroelectric power plant design, and good for the environment
Hydroelectric power is the oldest and the "greenest" source of renewable energy. In Germany, the potential would appear to be completely exploited, while large-scale projects in developing countries are eliciting ...
New method for estimating cost of small hydropower projects
In developing countries such as India, small hydroelectric power (SHP) projects represent a potentially large but largely untapped source of energy, primarily because the cost of constructing the sites is thought to be higher ...
Deep Green underwater kite to generate electricity (w/ Video)
Hydroelectric generator can be carried like a backpack
Norway plans the world's most powerful wind turbine
Norway plans to build the world's most powerful wind turbine, hoping the new technology will increase the profitability of costly offshore wind farms, partners behind the project said Friday.
