Though North America lags Europe on the wind energy front, with less cumulative installed capacity despite a vast geographical size difference, growth is strong and has only scratched the surface. Huge potential, particularly, exists in offshore installations, which represent just a small percentage of global wind capacity to date. Ocean-based turbines, both floating and fixed, take advantage of powerful, more consistent wind speeds and a topography that doesn't obstruct wind flow.
Many people mistakenly buy larger air conditioning units than they need because they believe that a larger unit will both operate and cool their house more efficiently. In truth, a larger unit could be less efficient.
Foundations are critical to the success of a wind turbine project, and since foundation types are as varied as the earth conditions and types of structures being supported, we examine below some of the considerations involved in foundation selection such as siting, cost, and geotechnology.
The average solar stock has moved up 124% since March 9th 2009 and the average gain for just the 8 Chinese based public solar companies ( CSIG,CSUN,JASO,LDK,SOLF,STP,TSL,YGE ) was an amazing 267.96% !
As photovoltaic technology increasingly penetrates mainstream markets rooftop solar PV system integration based on series configured arrays are becoming antiquated due to new system design architectures enabled by new inverter technologies.
With the advent of "home area networks" which allow consumers to be able to see what they are using in real time and make adjustments and decisions accordingly, this data could potentially be used by third parties to assist the consumer with those decisions. It will be important for that information to have privacy provisions built in so that third parties cannot access the data for purposes that have not been authorized by the consumer.

An Economic Case Study in Energy Financing
The ESD, the acronym for the Engineering Society of Detroit, is now 115 years old and it remains an august institution in the City of Detroit. Once housed in a magnificent marble building next to the Detroit Institute of the Arts it is an encompassing institution that holds many fine conferences on Engineering developments and Issues. Their recent conference held on March 3rd on Alternative Energy was something of a rousing affair, which we do indeed need since Michigan has been hardest hit in this recent Economic turn-down.
A distributed model revolutionized the way industrial-scale computing was delivered. Is it possible that something similar could be achieved for energy production?
Energy, Food, & Transportation for the Components of our Genes, Forevermore!
Aaron Fowles is the Specialist of Corporate Communications for SANYO North America Corporation's Regional Offices, based in San Diego. In this position, Mr. Fowles oversees all public relations activities, including media relations, strategic planning and implementation for all North American regional companies.
Renewable Energy companies need Public Relations (PR) for several reasons. The following are the top 10 things I believe every RE company should be aware of in 2010. Remember, the solar industry is still a nascent industry just at the beginning of its steep growth curve. But general awareness of solar and other renewables and their benefits is very low among the general public. The industry needs to educate and communicate with the American public so they better understand renewables and the bright future they can bring to our world.
By offering a means to install a solar power system without the initial capital, Power Purchase Agreements could be the Holy Grail for mass market adoption of solar. After being a major driver of solar installations over the last couple years, however, a number of obstacles still stand in their way. What makes these instruments so attractive?
