Honolulu-based Natural Power Concepts has recently designed a mobile, retractable-blade wind turbine that is capable to generate both solar and wind energy. Being equipped with solar panels, this turbine becomes one of the newest inventions in the alternative energy field.

Spain's industry ministry has reached agreements with two key renewable energy lobbies, the Spanish Wind Energy Association and Protermosolar, aimed at reducing special tariff premiums for wind farms and solar thermal plants.

While South Africa introduced a generous feed-in tariff of ZAR1.25/kWh (EUR0.134/kWh) for wind power last year (Windpower Monthly, May 2009), the system is not yet in place for independent power producers to sign power purchase agreements with state utility Eskom.

The wind industry is trying to find a solution to the problem by working with environmental groups, federal regulators, and other interested parties. They are trying to develop methods of measuring and mitigating wind energy’s effect on birds. The Fuller Wind Turbine offers hope to bird lovers and environmentalists.
