| Miles-High Kites Could Generate Electricity |  |
| The sky might literally be the limit for wind power — rotors spinning miles high could help supply electricity worldwide."There is a huge amount of energy available in high-altitude winds," said researcher Ken Caldeira at the Carnegie Institution`s Department of Global Ecology in Stanford, Calif. |

| Wind Could Provide 100% of World Energy Needs | |
| Damien1972 sends in a report on a study published in the Proceedings of the National Academy of Science, which finds that wind power could provide for the entire world`s current and future energy needs. "To estimate the earth`s capacity for wind power, the researchers first sectioned the globe into areas of approximately 3,300 square kilometers (2,050 square miles) and surveyed local wind speeds every six hours. They imagined 2.5 megawatt turbines crisscrossing the terrestrial globe, excluding `areas classified as forested, areas occupied by permanent snow or ice, areas covered by water, and areas identified as either developed or urban,` according to the paper. They also included the possibility of 3.6 megawatt offshore wind turbines, but restricted them to 50 nautical miles off the coast and to oceans depths less than 200 meters. Using [these] criteria the researchers found that wind energy could not only supply all of the world`s energy requirements, but it could provide over forty times the world`s current electrical consumption and over five times the global use of total energy needs."Read more of this story at Slashdot.

| SkyFuel Signs Agreement with Cogentrix to Install SkyTrough™ Collectors at Sunray | |
| Albuquerque, New Mexico June 23rd, 2009: SkyFuel, Inc. has signed an agreement with Sunray Energy, Inc., a wholly owned subsidiary of Cogentrix Energy, LLC, for the installation of SkyTrough™ collectors at Sunray`s 43 MW parabolic trough generating plant near Daggett, California, formerly known as Solar Energy Generation Systems I and II ("SEGS I & II"). The agreement with Sunray Energy, Inc., allows for the first commercial installation of the SkyTrough™, an advanced parabolic trough concentrator, which uses glass-free ReflecTech® Mirror Film reflectors. The agreement allows SkyFuel to integrate an array of SkyTrough™ solar collector assemblies into the Sunray plant to demonstrate their commercial viability in a full-scale, solar generating plant application. The SkyTrough™ installation is to be operational later this year. No business terms were disclosed. |

| Investing in Solar and Renewable Energy Related ETF`s | |
| Hello. I had a quick question. Is it possible to invest in the REW 40 index? I am new to investing, and was wondering if I could just invest in the REW 40 index, or do I have to invest individually in each company? Thank you for your help. -- John G., Plymouth, MA |

| How NJ Rose To #2 in US Solar Power | |
| While it`s not surprising that sun-drenched California leads the US with 67% of the country`s grid-connected solar power, how did a little East Coast state like New Jersey gain the No. 2 spot with nearly 9% (and double the power of No. 3 state Colorado)? Making this achievement more remarkable is that in 2001 New Jersey had only six PV installations, and now there are nearly 4000 generating >85 MW. |
