A sycamore seed design may be set to revolutionize the wind power industry. British engineers have designed a giant wind turbine called the Aerogenerator that would rotate on its axis mimicking the way sycamore seeds fly. The Aerogenerator has two arms coming out of its base to form a V-shape, with rigid "sails" mounted along their length.  The arms act like aerofoils as the wind passes over, helping to generate lift. It would measure nearly 900 feet from tip to tip and could generate Read more [...]

Wind power is now generating 2% of global electricity demand, according to the World Wind Energy Association. The countries with the highest shares of wind energy generated electricity: Denmark 20%, Portugal 15%, Spain 14%, Germany 9%. Wind power employed 550,000 people in 2009 and is expected to employ 1,000,000 by 2012. Globally 38,025 MW of capacity were added in 2009, bringing the total to 159,213 MW, a 31% increase.

The airline industry is taking its first steps towards green energy. British Airways has announced it is investing in a factory that will convert tonnes of household rubbish into enough jet fuel for all its flights from London City airport twice over. Some 500,000 tonnes of waste generated by Londoners will be used by the UK facility each year to produce 16 million gallons of fuel. Construction of the plant in east London will start within two years. It is set to produce fuel from 2014, Read more [...]
