Renewable Energy Sources. Read the latest research on renewable sources of energy such as solar energy, wind power, nuclear energy, hydrogen fuel, ethanol, methane and other alternative energy sources.
Researchers in Norway have succeeded in getting bacteria to power a fuel cell. The "fuel" used is wastewater, and the products of the process are purified water droplets and electricity. This is an environmentally-friendly process for the purification of water derived from industrial processes and suchlike. It also generates small amounts of electricity – in practice enough to drive a small fan, a sensor or a light-emitting diode. In the future, the researchers hope to scale up this energy generation to enable the same energy to be used to power the water purification process, which commonly consists of many stages, often involving mechanical and energy-demanding decontamination steps at its outset.
Researchers have revealed a new solution-based hot-casting technique that allows growth of highly efficient and reproducible solar cells from large-area perovskite crystals. The researchers fabricated planar solar cells from pervoskite materials with large crystalline grains that had efficiencies approaching 18%.
A new kind of radio chip is intended to warn when windows are left open. This way, you can avoid having the heat go out the window on cold days. The sensor also detects break-in attempts early on. The key: This maintenance-free chip powers up with energy supplied by solar power.
To excite and educate the American public regarding our energy options especially as they relate to the long term strength of our economy, our national security, and our stewardship of the environment.To accelerate the adoption of hydrogen and fuel cell based technologies as part of our nation’s overall energy portfolio, with an understanding of the role hydrogen does (universal energy carrier) and does not (independent energy source) play.
