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.
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.
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."
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.
