Biofuels can be made from various source materials such as waste from the winemaking industry and woody biomass. Reseachers are also looking for new methods to improve its environmental credentials as there is still controversy as to how green biofuels really are. Now, a team at the Catalysis Institute at Cardiff University is hoping to make biofuel production more efficient and sustainable by recycling the leftovers from the process.
Sunlight can be used to generate electricity either through a
photovoltaic effect, or by harnessing the heat produced by the light.
There are already hybrid systems that combine both, but scientists at
Korea's Yonsei University have now developed a type of hybrid setup that
they claim works better.
For decades we've been promised that hydrogen fuel cells will revolutionize our lives, but it always seems to be around the next corner. But that hasn't stopped one UK company from pursuing a near future in which iPhones and other devices are completely disconnected from the electrical grid and instead use embedded fuel cells to power themselves for a full week between recharges.
It may not be the first airport to fit solar panels to its terminals, but India's Cochin International Airport is set to become the first in the world powered entirely by solar. Situated in Kochi, the airport handled 6.8 million passengers in the 2014-15 financial year and forecasts a 300,000-tonne (330,700-ton) reduction in carbon emissions over the next 25 years as a result of the switch to solar.
The scientists that revealed the "world's first solar battery" last year are now, following some modifications, reporting its first significant performance milestone. The device essentially fits a battery and solar cell into the one package, and has now been tested against traditional lithium-iodine batteries, over which the researchers are claiming energy savings of 20 percent.
Wind turbines might be common sight all around the world, but situating them in open fields or on breezy ridges isn't always a practical option. Ideas like placing turbines under bridges have been proposed, but is that a viable alternative? According to new research out of Europe, the answer is yes.
It's now fairly common to hear about batteries being used to store power
generated by solar cells. A group of Indian scientists, however, have
eliminated the middleman. They've created a battery that incorporates a
titanium nitride-based photoanode in place of a conventional anode,
allowing the battery to charge itself using solar or artificial light.
Researchers have discovered an unlikely source of renewable energy, the naturally-occurring cycle that is water evaporation. Scientists at New York's Columbia University replicated this process in the laboratory and harnessed its energy to power tiny machines, one of which was a moving, miniature car. The team says the technology could potentially to be scaled up to one day draw power from huge resting bodies of water such as bays and reservoirs.
A team of researchers led by Stanford University's professor Mark Z. Jacobson has produced an ambitious roadmap for converting the energy infrastructure of the US to run entirely on renewable energy in just 35 years. The study focuses on the wide-scale implementation of existing technologies such as wind, solar and geothermal solutions, claiming that the transition is both economically and technically possible within the given timeframe.
recently did it to much acclaim, and now Daimler is doing it too – the
German automotive corporation is launching its own home/business battery
energy storage system. Developed by Daimler subsidiary Deutsche
ACCUmotive, the Mercedes-Benz energy storage unit utilizes lithium-ion
batteries to store energy generated by solar cells, wind turbines or
