It provides light where there is darkness, it gives a sense of safety and security, but it's also a power leech. The humble street light. Thankfully, the move away from the grid is already well underway with companies like Urban Green Energy busy transforming these familiar towers of light into self sufficient beacons that harness the power of the elements - in this case, it's a hybrid solution that uses both the wind and the sun.

Mobile operator Orange and renewable energy specialists GotWind know they’ve hit on a good, marketable idea. The companies have joined forces for a third consecutive year to showcase their outdoor charging solution at next month's Glastonbury Festival, the United Kingdom’s largest and hippest open-air music bash. This year Orange has unveiled a mobile phone charger prototype it’s calling the Orange Power Pump. By treading on what is essentially a standard camping air foot-pump, the kinetic energy created drives a small turbine inside the Power Pump. The energy is converted into electrical current, which recharges the mobile phone. The idea is not only simple, it cleverly encourages you to dance and charge your mobile at the same time. Read More

Solar power from photovoltaic cells are widely recognized as an integral part of a clean green future, and any development that can make these cells more efficient, no matter how small, assists in making this future a reality. A team of researchers at Georgia Tech have developed a surface treatment that boosts the light absorption of silicon photovoltaic cells by trapping light in three-dimensional structures and by making the surfaces self cleaning.

Green energy comes in many guises these days, from wind-power to wave-power. One of the more compelling of the new kids on the eco-energy block is salinity power, which uses the concurrence of salt-water and freshwater in estuaries and marries it with the natural, effortless process of osmosis.
