The plan calls for a mix of new renewable energy projects, energy conservation, gains in residential and generic propecia sale commercial energy efficiency, and developing plug-in vehicle infrastructure.
Vermont has a bit of click now cheap quality cialis an advantage going into this goal since it has the natural viagra scam lowest energy demand in New England and also has no coal-fired power plants. The Vermont Yankee nuclear plant that supplies one-third of its electricity is closing next year, so the state is aggressively pursuing renewable energy, mainly solar and wind power, to replace it.
Pipistrel-USA, a team from Pennsylvania has won the cialis online us NASA CAFE Green Flight Challenge by flying an electric plane 200 miles in less than two hours.
The Google-sponsored contest was created to spur development of electric airplanes and efficient aircraft designs and with a first-place prize of $1.35 million, it could very well succeed at that.
The contest took place at the visit web site buy cialis us Sonoma County Airport in California and required entrants to fly 200 miles in two hours while using less than one gallon of fuel per occupant or the electricity equivalent. Pipistrel-USA's plane, the Taurus G4, had two occupants and used less than a two-gallon equivalent of electricity. Check out the video above of a flight demonstration of wow)) buying levitra online the Taurus G4.
Both the winning Pipistrel-USA and the second place team flew electric airplanes. Only three teams out of 14 that registered met the contest's requirements.
Green building advocates and pfizer viagra 50mg construction product marketers have different views of what the greenest building material is. Different ways of determining what green means will lead to different results. But according to generic viagra from canada online a recent report from the U.S. Forest Service, wood is the greenest building material.
This analysis seems to rest largely on the carbon footprint of various construction materials.
"The argument that somehow non-wood construction materials are ultimately better for carbon emissions than wood products is not supported by our research," said David Cleaves, the U.S. Forest Service Climate Change Advisor. "Trees removed in an environmentally responsible way allow forests to how much does cialis cost continue to sequester carbon through new forest growth. Wood products continue to benefit the online cialis prescription environment by storing carbon long after the building has been constructed."
Wood is also unique as a renewable resource that actively sequesters carbon from the atmosphere. As they grow, trees absorb CO2 from the atmosphere and lock it into the structure of the wood. In doing so, wood is a carbon storage material, and that carbon is locked away until the wood decomposes or burns.
The report additionally recommends that USDA further its outreach efforts to educate the tramadol order online construction industry and the general public to be more aware of the suitability of order usa levitra onlineviagra on line uk wood for non-residential construction and to further study of the carbon benefits of the use of wood in construction.
Finding a parking space in downtown Pittsburgh is an easier prospect with the use of a new system called ParkPGH. The system, which is connected to 10 lots which together comprise 25 percent of the parking structures in the downtown area, monitors and predictively determines the best parking location for drivers looking for a place to leave their cars.
Unlike other parking monitoring systems which only report on current conditions at local parking lots, ParkPGH uses an algorithm designed by Dr. Robert Hampshire at Carnegie Mellon University that considers historical data as well as current conditions to price levitra predict where spaces will be when the driver arrives.
While at this point it may be more a convenience for drivers than a significant tool for cutting emissions and reducing drive time, developing systems like this to help route traffic can lead to more efficient travel, with the correspondingly reduced emissions and time savings.
Paris has introduced plans for a city-wide EV car-sharing network that will operate much like its successful Velib bike-sharing system. The car-sharing program will begin on December 5 with 250 EVs available.
The system will allow users to pick up and drop off the cars at different locations as long as they're returned to a designated parking spot. The chosen vehicles, called Bluecars, will be outfitted with computer systems that let drivers know where those parking spaces are.
The Bluecars are tiny, compact EVs being built by Pininfarina, who also makes Ferrari and www.beverly.org Maserati vehicles. The small EVs will have solid-state lithium metal polymer batteries that Pininfarina claims have a lifespan of 200,000 km and require no maintenance.
The patent application for this seems to be less about renewable power generation and is focused more on the attached LEDs being used as an animated display system. While it might be usable as a rapidly deployable system for power generation after an emergency, other portable wind-power generators seem more promising to be able to generate enough power to cialis cost 20mg be useful in the aftermath of a disaster. Nonetheless, it is always interesting to see new developments in wind power technology.
A 2,600-foot tower planned for the Arizona desert will be the world's second tallest structure and will be able to power 100,000 homes through hot air alone.
The solar updraft tower, designed by EnviroMission, will work by collecting hot air as it rises from the heated ground surrounding it. The very tall, narrow tower increases the strength of the hot air flowing upward, where it will turn 32 turbines along the way.
The tower will be able to produce 200 MW of electricity each day and, unlike solar power technologies, will be able to produce electricity at night too since heat from the ground will still be flowing upward and it will operate without the use of water.
This technology comes at a pretty steep price -- $750 million to build -- but since hot air is free, the operating costs going forward will be very minimal and the tower should last at least 80 years.
The tower will be made of concrete, which is a very carbon-heavy material, but the clean energy produced by the www.transitofvenus.org tower should cancel out the carbon emissions of making it within 2.5 years.
The WaterShed, designed and built by a team from the University of Maryland, is the winner of the 2011 Solar Decathlon. In addition to winning the overall competition, the Maryland entry also took first place in the Architecture category and real viagra gel second place in the Market Appeal category, and was in the top 5 in almost every category, including two other categories where they tied with several other teams for first place.
The winning house is just 876 square feet (81.4 square meters) in area. It not only utilizes solar photovoltaic (PV) and solar thermal, but also incorporates water collection, greywater filtration, and an edible garden wall among its numerous features.
Second-place in the Decathlon was won by Purdue University, and the team from Victoria University of Wellington, New Zealand received the third-place award.
The City of Austin, Texas is now the largest U.S. municipality to use only renewable energy to power its facilities. The city uses Austin Energy's GreenChoice, a voluntary program, to buy their electricity.
The city has bought about 400 million kWh of renewable energy from the program that will get the electricity from a wind farm in West Texas.
According to the National Renewable Energy Laboratory, Austin Energy sold more renewable energy than any other U.S. utility in 2010, selling 754 million kWh electricity from wind and landfill gas.
A new report from the International Center for Tropical Agriculture. a funded by the Bill and Melinda Gates Foundation, found that West Africa, where half of the world's cocoa supply comes from, is becoming less and less suitable for cocoa production as climate change brings higher temperatures and changing rainfall patterns.
The report says that between 2030 and 2050 land suitable for cocoa production will be slashed dramatically, with production having to move to less suitable areas. This change will make a huge impact on the worldwide industry and hurt the local farmers who rely on levitra sale buy cocoa crops for their livelihood.
Global demand for chocolate has been quickly rising as developing nations like China import more of it. The growing demand and drop in production will mean much higher prices for chocolate.
The study proposes finding new heat and www.absmag.fr drought resistant crops that could thrive in West Africa, while helping to transition cocoa production to more suitable areas.
A new section added onto a huge solar park in Eastern Germany now makes it the largest solar park in the world, but the more interesting fact about this section is that it was built over an old pit mine that had rendered that land useless for years.
The new section added 78 MW to the plant and, amazingly, it was constructed in just three months.
Using land that is otherwise undesirable is a great tactic for large solar developers because not only are they turning the remnants of something that once harmed the environment into an energy plant that is far gentler to it, but it also ensures that there isn't competition for that land for food production or other important uses.
The German solar park near Senftenburg now has a capacity of 166 MW.
