The Solar Energy Industries Association (SEIA) released the 2009 U.S. Solar Industry Year in Review, finding 2009 to be another year of strong growth despite the economic recession. Overall U.S. solar electric capacity, including both photovoltaic and concentrating solar power installations, increased by 37 percent. This was driven primarily by strong demand in the residential and utility-scale markets, state and federal policy advances and declining technology prices. As a result, total solar industry revenue reached $4 billion, a 36 percent increase over 2008. The solar industry contributed to the overall economy by adding 17,000 new jobs from coast to coast. The solar industry today employs 46,000 U.S. workers and supports an additional 33,000 jobs in other sectors.
Known as the " Salamander, " this car operates on zinc oxygen energy fuel cells. Also known as ZOE, the fuel cell generates electricity through the metal's oxidation process. It can be recycled by using sun power to return the oxidized zinc back to the original metal form. 288 of these little cells provide enough power for the lightweight vehicle to reach speeds well over 200 miles per hour. Of course, 80 miles per hour is the design speed and combined with brisk acceleration makes it nimble enough to function well in modern traffic. Local Taipei news video of the car in action here.
Buyers of electric vehicles will get the grant and be exempt from vehicle registration tax, the government said. Ireland's Electricity Supply Board is rolling out 3,500 charge points by December 2011, with roll-out already under way in Dublin and charging points due to be installed in Cork, Galway, Waterford and Limerick. Ireland said it's aiming for 10% of the country's vehicles to be electric by 2011. Nissan is due to roll the Leaf, an all-electric five-seater, early next year, and Renault will launch its Kangoo Z.E. electric vehicle later in the year.
A new type of environmentalist is emerging, using nanotechnology based products as a way of reducing their impact on the environment and reducing their energy use in a variety of ways.
If you are a building owner that is considering a solar panel installation, there are several questions you should ask before signing any contracts. What is the best mounting method for installation on my rooftop? Do I need a new warranty to protect myself from any damage? Which type of system will give me the best ROI? Do I work with my old roofing company or do I need to find a structural engineer?
Altenergymag interview with Barry Kay, President of Kay + Sons, a national leader and expert in how light is managed in buildings of the future.
The aircraft made its maiden voyage Wednesday in Switzerland, as a team of engineers and adventurers marked an important step in a $93.5 million project to build the first aircraft capable of circumnavigating the globe without a drop of fuel. The plane itself, Solar Impulse, is an unwieldy beast. Wings as wide as those on a 747 are decked out with solar panels to provide enough power to keep the 3,500-pound craft cruising at about 44 mph. Test pilot Markus Scherdel managed to take the aircraft almost a mile above the Swiss countryside, executing simple turns during the 90-minute flight before making a successful landing.
United Parcel Service (UPS) has added an additional 200 hybrid delivery vehicles to its fleet of low-emissions and alternative energy vehicles. With this latest addition, UPS now has more than 20,000 green vehicles in its fleet! The 200 new HEV package cars are expected to reduce fuel consumption by roughly 176,000 gallons over the course of a year compared to an equivalent number of traditional diesel trucks. The hybrids also should reduce by 1,786 metric tons the amount of CO2 gases released annually into the atmosphere.
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.
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.
