The increased construction of desalination plants due to the steady fall in the cost of several key technologies for seawater-to-freshwater conversion is projected to generate a cumulative capital investment of $87.8bn worldwide from 2010 to 2016, says a report from Pike Research.
Deepwater Wind, a company based in Providence, Rhode Island, has drawn up plans for what could be the largest wind farm in U.S. waters, the company announced last week. The proposed farm would generate a huge 1,000 megawatts of power and would be located 18 to 27 miles off the coast of Rhode Island and Massachusetts at a depth of 52 meters—considerably deeper than any other large scale wind project to date. By moving into deeper waters, turbines can harness stronger, more sustained winds. And the massive turbines the company plans to use—each capable of generating more than 5 megawatts of power, with blades rising 150 meters above the water's surface—will be nearly invisible from shore, thereby avoiding potential legal battles with coastal communities that perceive the turbines as eyesores. Four-legged steel platforms rising from the seafloor will allow Deepwater Wind to operate in depths more than twice those of conventional steel "monopole" wind turbine platforms. As water depth increases, the diameter of monopoles must increase exponentially, making them uneconomical in water deeper than about 20 meters. By using a four-legged design, company officials say they will be able to work in depths that were previously prohibitively expensive.

Corvus Energy selects Jastram Technologies as its exclusive Canadian partner to distribute Corvus Energy's lithium-ion batteries to Canada's Commercial, Recreational and Military Marine Sectors.
A plug-in hybrid electric vehicle (PHEV) is the logical next step for the millions of people who own hybrid cars or who want an extremely efficient car. PHEVs solve a lot of problems quickly. They combine the benefits of pure electric vehicles and hybrid electric vehicles. Much like pure electric vehicles, they plug into the electric grid and can be powered by the stored electricity alone. Similar to hybrid electric vehicles, they have engines that enable them to have a greater driving range and that can recharge the battery.
"Cracker Barrel will be rolling out fast chargers called the Blink, made by ECOtality, Inc, at select restaurant locations across Tennessee for Phase 1 of the project.
Greenleaf Power, a biomass power plants owner and operator, has signed a deal to buy 100% of the stock of Colmac Energy, including the 47MW biomass power plant operated by Colmac's majority shareholder American Consumer Industries since its construction and initial start-up in 1992.
NAFTC Studios' plan to open a state-of-the-art film studio in Lakeshore, Ontario is revitalized thanks to the inclusion of a 500 kW solar power plant. The proposed studio failed to meet provincial and municipal standards back in 2005 and the project was put on hold - until now.
In this article I'll show you how to untether from the grid, and avoid a smelly, noisy, fuel consuming generator except in extreme weather conditions. It can be pricey for a good system, but you'll have minimal ongoing expenses, unlike fuel and maintenance on a generator. The less power you consume, the less power you will need to generate, keeping the system costs down. It's important to start with conservation.
From a materials perspective, racking represents roughly 5-10% of the system cost. That said, the labor required to install the modules on the racking system costs twice as much as the racking material involved and can account for up to 66% of the total installed cost of a system. According to expert industry analysts, the speed and ease of installation for the racking system can directly impact roughly 40% of the total installed cost.
