Researchers Mark Delucchi and Mark Jacobson conducted a study of what renewable energy resources would be required to meet world demand by 2030.  The number of wind and solar installations required is astonishing.  It can be done but the policy changes required of political is more than likely insurmountable.

The Maldives, a collection of 1,190 coral islands gathered into 26 atolls off the southern tip of India, is taking global warming seriously.  After all the highest point anywhere in the Maldives is 2.4 m or a little over 7 feet.  Because of the problems they are already experiencing and those projected, a number of green energy initiatives have been implemented.

10:10 is the name of a movement to decrease carbon emissions by 10 percent a year starting in 2010.  October 10th, 2010 is also a day similar to Earth Day when individuals and companies are asked to engage in activities to reduce their carbon footprints.  Scotland and Denmark both have come out with statements claiming that they will achieve significant decreases by 2025 and 2050 respectively.  On another note, in an effort to increase the awareness of 10:10’s mission, a bizarre film was commissioned from Richard Curtis that has caused quite a stir.

Recycled Island is a great idea for getting rid of the floating plastic dump in the Pacific.  The island would be built where the trash is located and would convert the waste onsite cutting down on cleanup and building costs.  It would be between Hawaii and San Francisco in the heart of the Pacific Ocean’s currents.

Both Princeton and Georgia Tech have developed new technologies that may make all of the devices we carry cheaper and lighter.  Princeton has developed plastic electronics that can be molded into any shape.  Princeton’s development will also work very well for lowering the cost of solar panels.  Georgia Tech’s tiny self powering nanogenerators can be used in a variety of devices reducing the need for batteries.

Hydrokinetic Laboratory has developed the HyPEG short for Hydrokinetic Powered Energy Generation.  The HyPEG can be used either off-shore or in tidal currents.  It is safe for aquatic life regardless of its placement.

Lockheed Martin might be better known for its weapons and airplanes, but it also has skills that will be used to create large scale projects using  Ocean Power Technologies’ (OPT) PowerBuoys.  Together the companies expect to develop scalable wave energy projects for use around the globe.

Pelamis Wave Power Ltd(PWP) is developing the new Sea Snake for installation next spring in Orkney, northern Scotland.  Previous installations have used the first generation  Sea Snake.  This will be the first installation of the PWP’s second generation Sea Snake.

The Guardian and Cleantech Group, published the 2009 Global Cleantech 100  showcasing the most promising clean technologies around the world.  All the Companies listed are private companies so it is not surprising that China, although housing the largest solar cell manufacturer in the world, does not have a single company on the list.
