Sea Change: Recommendations For Offshore Wind Farms

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.

What Size Air Conditioner Do I Need?

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.

In Support of Wind Energy: The Foundations that Underlie Wind Projects

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 Solar Industry: Where it has been, where it is now and where it has to go

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% !

Power Optimization Approaches for Trouble-free Project Execution and Superior System Performance

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.

AltEnergyMag Interview - Data Privacy and the Smart Grid

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.

Tesla Wins Alternative Energy Rally

A Tesla Roadster has become the first electric vehicle to win the Monte Carlo Alternative Energy Rally and the first to win an FIA-sanctioned competition. Driven by Formula One driver Erik Comas, the Arctic white Roadster beat 96 competitors in range, efficiency and performance. The Roadster's victory in the three-day, nearly 1,000-kilometer challenge also marks the first time an electric vehicle has dominated a certified Federation Internationale de l'Automobile competition. The Roadster scored definitive victories in two additional categories, including the Efficiency Cup and the Electric Vehicles Cup.

China vs U.S. in clean energy investing war

This is a war we want to encourage. China overtook the United States in renewable energy investments for the first time ever in 2009, attracting nearly twice as many dollars and becoming the world's largest market for clean energy projects. Renewable energy investments in China - mostly wind farms - totaled $34.6 billion in 2009, according to report released Thursday by the Pew Charitable Trusts and Bloomberg New Energy Finance. In the United States, $18.6 billion was spent. The report noted that over 700,000 clean energy jobs have been created in the Untied States since 1998, and with so much money being invested in the alternative energy market, this was likely just the beginning.

Electric Vehicle Charging Stations in US

What's billed as the biggest roll-out of electric vehicle infrastructure in the world is about to begin in the United States. Urban planners are deciding where to locate more than 11,000 charging stations in 11 major cities. They want those stations up and running when the first mass-market electric cars from Nissan and General Motors go on sale at the end of this year. Last year, the Department of Energy awarded $100 million to eTec, an electric transportation research and development firm, to build electric vehicle charging networks in five states. eTec is installing more than 2,000 electric car chargers in the greater Seattle area in western Washington, and another 2,000 at homes and public places in four Oregon cities. They'll be near shopping centers, fast food restaurants and movie theaters, "the variety of places that people think about when they're able to park and leave the vehicle for an hour or two."

Chevron Tests 7 Solar Technologies at an old refinery site in California

The oil giant Chevron has transformed an old refinery site in California into a test bed for seven advanced photovoltaic solar technologies, which the company is evaluating for use at its facilities worldwide. Chevron is unveiling 7,700 solar panels installed on 18 acres in Bakersfield, the capital of California's oil patch. Called Project Brightfield, the plant will generate 740 kilowatts of electricity to power nearby oil operations. Any excess electricity will be fed to the power grid. Chevron will test the technologies for three years and decide which might merit use at the company's facilities, or by Chevron Energy Solutions, which builds solar power plants and installs solar arrays for commercial customers.

China's State Grid Corp. to accelerate building of electric vehicle charging stations

The State Grid Corporation of China (SGCC) has announced plans to accelerate the building of electric vehicle charging stations in 27 cities in 2010. Plans are for 75 public charging stations, 6,209 AC charging spots and some battery replacement stations, with the aim of supporting the country's "Energy efficient and new energy vehicle pilot program." Since 2006, the SGCC has acquired 101 electric vehicles and constructed 30 pilot charging stations, and has cooperated with the Beijing municipal government in the design of seven electric bus lines and manufacture of 58 electric buses.

FCC's National Broadband Plan

The Federal Communications Commission (FCC) unveiled the first U.S. National Broadband Plan on Tuesday morning. And — what we're particularly interested in — there's an entire chapter on Energy and the Environment (Chapter 12, Page 245) . The National Broadband Plan looks at how broadband can be used to build out a smarter power grid, make information technology more efficient and make transportation cleaner. Some recommendations include: States should reduce impediments and financial disincentives to using commercial service providers for Smart Grid communications. The Federal Communications Commission (FCC ) should start a proceeding to explore the reliability and resiliency of commercial broadband communications networks. The National Telecommunications and Information Administration (NTIA) and the FCC should continue their joint efforts to identify new uses for federal spectrum and should consider the requirements of the Smart Grid. Congress should consider amending the Communications Act to enable utilities to use the proposed public safety 700 MHz wireless broadband network.
