Energy efficiency and renewable energies are becoming an important fact in architecture today. Since new and more affordable technologies emerge, solar harnessed electric energy and heating, as well as passive and active systems of heating and cooling are becoming more widely spread. This way of ecological living is practiced by BedZED – an environmentally friendly… »
The high winds were thought to be a rich potential source of renewable energy, however, a study by researchers from the Max Planck Institute for Biogeochemistry in Jena, Germany, shows that the near absence of friction and absence of strong propulsion cause the jet streams that sweep the upper atmosphere to harness about 200 times… »
A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and more durable compared to materials currently used in blades of wind turbines. He came up with a polyurethane blade reinforced with carbon nanotubes, which make the material eight times tougher compared to other materials which are currently used as… »
last year we wrote about a group of researchers at the California Institute of Technology (Caltech) who have been conducting a field study at an experimental two-acre wind farm in northern Los Angeles County. In their new findings, the researchers came up with a way to increase the power output of wind farms simply by… »
The Y. S. Sun Green Building Research Center (Magic School of Green Technology) of the National Cheng Kung University (NCKU), the first energy-saving and zero-carbon building in Taiwan, has obtained the highest green building certificates from Taiwan’s Ecology, Energy Saving, Waste Reduction and Health (EEWH) and the U.S. Leadership in Energy and Environmental Design (LEED)… »
Suzlon Energy Limited (SEL), India’s largest wind turbine manufacturer, received LEED Platinum award for their new corporate headquarters in Pune, Maharashtra, India. Developed on an area of 41,000 square meters (10.13 acres) with a capacity to house 2,300 people, One Earth is one of the largest green building projects in India. The green approach has… »
In the Los Angeles basin, the challenge of finding suitable space for large wind farms has prevented further progress in the use of wind energy. However, researcher John Dabiri, associate professor of aeronautics and bioengineering at California Institute of Technology (Caltech) and head of Caltech’s Biological Propulsion Laboratory, is using the bioinspiration from fish schooling… »
Clean, renewable energy is freely available – in the form of wind, sun, water and potential other forms we haven’t discovered yet. However, harnessing the energy with reliability and in a cost-effective manner remains a barrier. Wind power is one of the fastest growing alternative energy markets and researchers all over the world are developing… »
