The first full-scale Neptune tidal stream device is the design of Edinburgh's Aquamarine Power Ltd. The 2.4MW Neptune demonstration design is on schedule for delivery in 2010 at the UK tidal test centre, known as the European Marine Energy Centre (EMEC), located in Orkney, as a precursor to commercial deployment. The device comprises two horizontal axis tidal turbines, which will be mounted on a single monopile for the commercial demonstrator. The device features bi-directional (flood and ebb) generation, with its design heavily influenced by wind turbine technology and as such gives predicted efficiencies of up to 45 per cent.
In spite of the weakened economic conditions in countries around the world, electric power utilities are proceeding with investments in both their infrastructure and "smart grid" automation programs according to a study released by the Newton-Evans Research Co. Newton-Evans found that a majority of the 110+ officials from 38 countries participating in the just-completed study indicated that capital spending for control systems, substation automation, smart grid related programs, distribution management, advanced metering rollouts, and infrastructure equipment for transmission and distribution grids will remain as originally projected a year ago.

XsunX, Inc. a thin-film photovoltaic solar technology company, announced today that it had entered into a two-year supply contract for the sale of four (4) megawatts of it ASI-120 TFPV solar modules to an Oregon based firm specializing in over 20 years of commercial project development.
It looks like a giant funhouse mirror. But the big new dish atop South Table Mountain could be a renewable energy breakthrough that helps make concentrated solar power more affordable and appealing to utilities and their customers. For the next several months, NREL engineers will be testing the performance of SkyTrough , an innovative parabolic trough that is coated with a gleaming reflective skin instead of mirrored glass. Parabolic-trough systems concentrate the sun's energy through long U-shaped mirrors. The mirrors are tilted toward the sun, focusing sunlight on a vacuum pipe that runs down the center of the trough.

The use of solar technology for the production of energy is becoming more important as we strive to become less dependent upon diminishing supplies of fossil fuels. As the production levels of solar cells increase so too does the use of lasers. The attributes of non-contact processing, flexible beam delivery and precise control make the laser the ideal tool for processing these fragile components. With a number of different micro-machining processes to be performed during the production of mono and polycrystalline solar cells, it is essential that the most appropriate laser source is used .

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
