With New PV Installation, DIA will be Largest Solar Producer in CO-



In addition to its 3.6-megawatt (MW) ground-mounted solar array, Denver International Airport (DIA) will be implementing another 4.4 megawatts of renewable energy this fall. With a grand total of 8 megawatts, the installation will place DIA as the largest photovoltaic energy producer in all of Colorado. Constellation Energy will finance, own and operate the solar installation and DIA will purchase the electricity produced by the system from Constellation over a 20-year period. “Denver’s airport has a widespread reputation as a green airport. Our partnership with Oak Leaf Energy, Constellation Energy and Intermountain Electric not only expands our sustainability efforts, but is a great example of public-private partnerships advancing the green economy,” says Kim Day, aviation manager for the airport. Yingli Green Energy will supply the PV panels for the project. Construction will begin early this fall and is expected to wrap up early 2011. The new installation will reportedly supply the airport with 7,000 MWh of electricity and reduce 5,000 metric ton

The first stadium capable of generating all its own electricity.

Another rendering of Lincoln Financial Field, scheduled to be completed by September 2011.
But a growing number of sports buildings from Boston to Los Angeles are becoming efficient in other ways, by saving energy and reducing waste with solar panels, low-flush toilets and composting.
On Thursday, the Philadelphia Eagles announced perhaps the most ambitious green initiative yet: the installation of about 2,500 solar panels, 80 20-foot-high wind turbines and a generator that runs on natural gas and biodiesel so that Lincoln Financial Field, the Eagles’ home, will be the first stadium capable of generating all its own electricity.
Becoming self-sufficient in energy is the latest in a string of environmentally friendly measures the Eagles have taken since they opened their stadium in 2003. (Coincidentally, the team’s primary color is green.) Since then, many teams have introduced similar efficiency programs, and the four major sports leagues have set up programs to help their teams share information about how to use less energy, reduce waste and save money.
As large as they are, sports stadiums consume just a sliver of the nation’s energy and produce a fraction of its waste. But they are seen and used by millions of Americans every day, which has helped leagues counter the perception that sports teams are wasteful enterprises and in fact can convey socially responsible messages to fans of all political and economic stripes.
The Eagles’ green efforts “underscore the position that we are all very visible and can make a significant effort in our communities,” said Roger Goodell, the commissioner of the N.F.L. “We think it’s smart business and the right thing to do.”
To become self-sufficient, the Eagles have hired Solar Blue, a Florida-based company that will spend more than $30 million to install the solar panels, wind turbines and dual-fuel co-generation plant by the start of next season. Solar Blue chose vertical wind turbines because they produce less noise than bladed ones. They will also capture energy at night. The panels and turbines will meet about 25 percent of the stadium’s energy needs, with the generator covering the remainder, and will be visible to fans in the stadium, on television and to drivers passing by.
The Eagles will pay Solar Blue fixed amounts for their energy with increases of 3 percent a year over 20 years, which gives Solar Blue a guaranteed buyer and the Eagles a predictable source of renewable energy without worrying about erratic spikes in prices. The Eagles expect that their alliance with Solar Blue will help reduce their energy costs by almost 25 percent in the first year. Solar Blue can sell any excess energy it creates to the local utility, PECO.
“This is an opportunity to not be the stereotypical sports franchise that is not on the cutting edge,” said Jeffrey Lurie, the owner of the Eagles, who, with his wife, Christina, created a Go Green sustainability program in 2003. “We’ve read a lot that excellent environmental practices are too expensive or not wise for a company. We challenged that.”
In some ways, stadiums and arenas are ideal for green initiatives because they typically have large roofs for solar panels and ample space for other equipment. Teams and their fans also consume vast amounts of energy, food and beverages, metals and paper goods that can be reduced or recycled.
Sports facilities are also where Main Street and Wall Street collide. Every day, hundreds of thousands of Americans watch sports live at arenas where companies from caterers to chemical makers have their goods on display. Teams are increasingly using their leverage to force these suppliers to go green with them.
“When sports say we’re going to go solar or waterless, that sends an enormous message to the supply chain,” said Allen Hershkowitz, who leads the Natural Resources Defense Council’s sports greening initiative.
For example, the Eagles asked Aramark, the food service and cleaning contractor at Lincoln Financial Field, to use nontoxic cleaning supplies and to switch to more environmentally friendly cups and dinnerware. All toilet paper, tissues and towels at the team’s facilities are made from 100 percent recycled fibers, which has helped the team recycle nearly 32 percent of its waste, twice as much as in 2008.
The team composts more than 25 tons of organic waste, and more than 10,000 gallons of grease and used kitchen oil last year were sent to processors that converted it into biodiesel. These and other measures, including halving the amount of water used by urinals, have helped the team save more than $3 million since 2005. The Eagles, like other teams, have been able to generate new revenue by selling sponsorships to companies interested in being linked to their green initiatives.

Stop Comcast from blocking Netflix

http://act.credoaction.com/campaign/comcast_netflix/?rc=fb_share2


It's as brazen as it is outrageous. At the very same time that the FCC is deliberating the fate of our open Internet, cable giant Comcast threatened to block Netflix from delivering streaming movies to Comcast's own broadband customers.
Without strong net neutrality rules, companies like Comcast can demand fees from innovative companies like Netflix in an attempt to choke consumer freedom and coerce users to adopt its own video services instead.
Tell the FCC: Don't let Comcast block Netflix. Support the strong net neutrality protections President Obama promised during his campaign.
Comcast only relented after it was able to extort a fee from the company that supports Netflix's movie streaming service, Level 3. According to the AP, 3 asserts "the fee violates the principles of an 'open Internet.' It also goes against the Federal Communications Commission's proposed rules preventing broadband Internet providers from favoring certain types of traffic." 1
It's a critical time to speak out about this. After stalling for months, the FCC is poised to exercise its power and issue net neutrality regulations at a meeting scheduled for December 21. We expect FCC Chairman Julius Genachowski to release his draft plan for protecting an open Internet in advance of that meeting -- as early as this week.
There is only one Internet, and consumers should be allowed to access any legal website, service or application on any device of their choosing (whether they're accessing the Internet wirelessly or not). Furthermore, broadband providers cannot be allowed to employ paid prioritization schemes to give favored network access to some websites or services over others. And finally, the rules must define the terms in a way that avoids the huge loopholes favored by industry and rests on sufficient legal basis.
Tell the FCC: The big cable companies and telecoms will destroy our open Internet if you do not regulate strong net neutrality protections.
Clearly the big telecom and cable companies feel confident that the FCC will bend to their will, rather than protect consumers and preserve our open Internet. What makes Comcast's behavior even more outrageous is that in addition to the FCC's pending decision on net neutrality, it also must rule on Comcast's bid to buy NBC. Without tough and binding FCC rules, will Comcast ensure that NBC content is available online to its subscribers, but video streams from other channels download at a slower rate or not at all?
This is about more than getting movies via Netflix instead of Comcast. It's about the ability of media monopolies to decide what information we can access via the Internet. Will Fox News stories be carried in the fast lane while Democracy Now! is relegated to slow lane or perhaps blocked altogether?
President Obama campaigned on a platform that included strong net neutrality provisions. It's time for his FCC to deliver. 1 "Web delivery firm says Comcast taking toll on data," Associated Press, November 29, 2010.

How many Sun Miles® can a Nissan LEAF get?

How many Sun Miles® can a Nissan LEAF get?

Share
leaf-99-sun-mileseditors-blog-entry3The big news in the EV world is that the EPA has officially rated the Nissan LEAF at 99 miles per gallon. The designation has generated plenty of talk and controversy on the internet. But, as far as we can tell, no one's been talking about how many Sun Miles® the LEAF will be able to roll up.
Sun Miles® is SolarChargedDriving.Com's term for miles driven by an electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV) whose batteries have been charged using solar energy and/or using electricity from kWh credits amassed via solar offset generation.
The answer to the question of how many Sun Miles® the LEAF -- or any other EV will get -- is pretty simple: Your EV will get as many Sun Miles® as you produce with a home solar system.
Of course, you'll need a home solar system to produce Sun Miles®, and, as far as we're concerned, the bigger the better. That is, the bigger the solar system, the more Sun Miles® it'll produce for your LEAF, Ford Focus Electric, Tesla Roadster, etc.
In our humble opinion, the best scenario -- and we realize not everyone can achieve this -- is one in which your home solar system covers 100 percent of your home electric use plus all of the annual miles you drive in an EV. That way, you'll know for sure your electric LEAF not only gets 99 miles per gallon -- whatever that really means -- but that it's 100-percent sun-powered too.

Solar carport revolution is underway in U.S.

Growing interest in solar carports and solar-powered EV charging stations doesn’t necessarily mean that the electric car + solar connection is going to take off. But it does mean that the solar world is quickly waking up to the potential of what just might turn out to be a better surface area to cover with solar panels than the roofs of buildings: The vast blacktop parking areas that populate the U.S and which make up a significant portion of the estimated 45,000 square miles of so-called "impervious surface areas" in the U.S, or an area roughly equivalent in size to the state of Ohio.
And, in case you haven’t noticed, interest and investment in solar carports and solar-powered EV charging stations (a solar carport does not necessarily offer EV charging) is clearly on the rise.
Solar carport vs. solar-powered EV charging station

Solar carport = A basic parking structure with solar panels on it. The electricity the panels produce either flows directly into the electric grid (very common) and/or is stored via batteries on site (uncommon). Charging stations for electric vehicles are not necessarily integrated into a basic solar carport – although they can be, at which point a solar carport is more accurately described as a solar-powered EV charging station (see below).
capport-nyit-solar-carport-small

Solar-powered EV charging station: A solar-powered EV charging station is a specific type of solar carport – one equipped with charging stations for electric vehicles. When solar energy is being generated by the solar panels on top of a solar-powered EV charging station (panels can sometimes be on a building rooftop nearby), that energy flows directly into the batteries of an EV parked underneath it – or next to it. When no electric vehicle is plugged in to the EV Charging Station, typically the electricity generated by the solar panels on the solar part of the charging station flows into the general electric grid. If not enough electricity is being produced by the solar panels on site to charge the batteries of the EVs that have plugged into the station, that electricity is drawn from the general electric grid. It is possible to have an off-the-grid solar-powered EV charging station. For instance, SunPods, which makes portable EV-charging stations, makes a version of the SunPod which offers battery storage for the solar-generated electricity.
For instance, this week almost immediately after REC Solar announced that it was going to be building what it said would be America’s largest solar carport at a VA hospital facility in Arizona at 2.9 megawatts, Solaire Generation announced an even bigger solar carport project: A 4.1 megawatt installation that will be built at a Fortune 100 corporate office campus in central New Jersey.
SolarChargedDriving.Com has already written about dozens of solar carports and solar-powered EV charging stations in the past 10 months. In fact, we’ve mapped many of them onto our unique Global Map of Solar-Powered Plug-In Stations.
That we've consistently written about solar carports and solar-powered EV charging stations is a sure sign that there's a lot going on in this arena.
You don't need to stay on our web site to see that this is true. If one takes a quick glance at YouTube, a search for solar carports and solar-powered EV charging stations reveals a slew of videos -- the vast majority posted within the last year -- highlighting the solar + auto and/or solar + EV combo.
List of YouTube videos on solar carports
Below are quite a few of these videos. They provide strong evidence that the concept – and practice -- of solar-charged driving is on its way up. That’s good news for the environment, for national fueling independence, and, on a more everyday level, for those of us would appreciate more shade spots to park our car in.

Põhu- ja savimajade ehitus kogub populaarsust

Ökoehituse Ühingu esindajad Knut Klais ja Ain Siska olid messile vaatamiseks toonud põhupakid, millest maja ehitatakse.
Foto: Taimi Plado
MESS • 26.–28. novembril Tartus toimunud ökomessi eesmärgiks oli tutvustada tooteid ja teenuseid, mis aitavad kooskõlas loodusega keskkonnateadlikult elada. Esmakordselt oli väljas maheloomade näitus, sai osaleda erinevate töötubade tegemistes ja saada ökoehitusalaseid nõuandeid. Mahe- ehk ökoloogilise põllumajandusega hakati Eestis tegelema 1989. aastal. Võrumaa on hetkel mahetootjate arvu poolest esikohal. 2008. aastal jõudis poelettidele kodumaine maheliha, esimesed mahemeierei tooted aga vaid mõned aastad varem. Tarbijate huvi oma tervise vastu kasvab ja üha suuremat tähelepanu pööratakse lisaks toidule ka tervislikule elukeskkonnale. Euroopas levinud ökoehitus näitab ka Eestis tõusutrendi. Keskkonnateadlikku ehitust ja säästvat renoveerimist olid messile tulnud tutvustama Ökoehituse Ühingu esindajad. Põhumajade suhtes ollakse umbusklikud
Ökoehituse Ühingu esindaja Knut Klaisil on endal põhumaja Põlvamaal. Hoone on elamiskõlblik aastaringselt, kuid kuna maja on väike, vaid 50 m2, siis on see kasutusel ainult suvekoduna. Klais toob esile põhumajade hea soojapidavuse. Põhuseinte soojusjuhtivuseks on mõõdetud 0,16 W/m2K. Võrdlusena võib tuua puidu soojusjuhtivuse, mis on 0,12–0,14 W/m2K. Savimaja vastava näitaja on 0,25 W/m2K. Klais on oma maja ehitanud ainult taaskasutatavatest materjalidest. Selline materjali valik võimaldas omahinna hästi alla viia. Kogu ehitustöö on ise tehtud, sealhulgas ka ahi ja korsten. Ökoehitust käis ta õppimas Saksamaal ja Belgias. Nüüd jagab ta saadud teadmisi kursustel teistelegi. Eestis on tema hinnangul viis-kuus inimest, kes põhumaja ehitust põhjalikumalt tunnevad. Ehitushuviliste ring aga aasta-aastalt laieneb. Põhumajade arvu Eestis on Klaisi sõnul raske öelda, sest mõned inimesed ehitavad ise oma teadmistega ja täpne informatsioon nende tegemiste kohta puudub. Võrumaal ei ole tema teada valminud veel ühtegi põhumaja. Üks olevat siiski tegemisel, karkass on juba olemas. Erinevalt üldlevinud arvamusest, et kõige suurem oht põhust hoonele on hiired, tuleb selleks siiski lugeda niiskust, mis võib olla tingitud nii põhu ebaõigetest koristus- ja pakkimistöödest, ebaõigetest ladustamisoludest, aga võib sattuda konstruktsiooni ka kasutusaja jooksul. Kui põhk ei ole saanud niiskust ja on umbrohuvaba, siis on sellest ehitatud majade eluiga sarnane puitmajade kasutuseaga. Kui hirm näriliste ja niiskuse ees on siiski suur, võib maja ehitusel kasutada põhu asemel järve- ja mereroopakke.
Iseenese tarkusest ei maksa maja ehitada
Saviukumaja OÜ esindaja Liina Asu-Raag, kelle savimaja valmis neli aastat tagasi, usub, et kõik inimesed, kellel on ehituslikku taipu, saavad lihtsama savi- ja põhuhoone ehitamisega hakkama. Püsivamate majade rajamisel soovitas ta siiski palgata spetsialisti, kes oskaks pakkuda ökoehituse viljelejatele erinevaid lahendusi. Ka Rõuge vallas asuva osaühingu Amain Ehitus omanik Ain Siska ei soovita päris omapäi savi- ja põhumaju ehitama hakata, sest ehitusfüüsikalisi teadmisi on nende tegemisel vaja rohkem kui tavamaja ehitusel. Kui peetakse kalliks eriteadmistega ehitaja palkamist, siis peaks vähemalt konsultandiga nõu pidama. Pole vaja ise hakata jalgratast leiutama, kui teiste vigadest on võimalik õppida. Looduslikud materjalid käituvad erinevalt ja sellega ei osata arvestada. Asu-Raag tunnistas, et praegu teeks temagi oma majas nii mõndagi teistmoodi. 99 protsenti tema majast on tehtud savist, nii põrandad, lagi kui seinad. Teistel soovitab ta saviga mitte liialdada. Mõned hoone osad võiksid olla puidust ja kivist. Savil on omadus niiskust siduda. Kuna väljaandmisprotsess on aeglane, siis on toad liiga kuiva õhuga. Ümbertegemine ja parandamine ei ole aga just eriti odav. Asu-Raagi hinnangul läheb savimaja ehitamine niigi tavamajast veidi kallimaks maksma. Materjal on küll odavam, kuid ajakulu on suurem. Vanade raamatute põhjal teab ta öelda, et käsitsi on võimalik valmistada 500 plokki päevas. Plokkide kuivamiseks kulub kuni kaks kuud.
Kergsavimaju on Võru- ja Põlvamaal kokku kümmekond. Sellelgi suvel ehitati kolm-neli maja juurde. Ta usub, et üheks põhjuseks, miks inimesed üha enam ökomaju hindama hakkavad, on allergilisuse tõus. Viimaste uuringute järgi on Eesti laste allergilisus kasvanud ja 18 protsenti kümneaastastest lastest on millegi suhtes ülitundlikud. Siska juhib siinjuures tähelepanu asjaolule, et maja sisekliima on tervislik ja maja saab ökomajaks nimetada ainult siis, kui tegemist on terviklahendusega, see tähendab planeerimisest viimistluseni kasutatakse ökoloogilisi ehitustehnoloogiaid, loodussõbralikke materjale ja seadmeid.
Eesti üks suuremaid ökoloogilistest materjalidest valminud hoone, Võrtsjärve külastuskeskus, asub Emajõe alguses Tartu – Viljandi maantee ääres Kolga-Jaani ja Rannu valla piiril asuval Rannu-Jõesuu puhkealal. Maja ehitusel on kasutatud puitu, puitlaastu, savi ja põhku.

Man combines boat and lawnmower to create amphibious 'Shortcutter'

Amateur inventor John Hinton has launched an amphibious assault on the misery of the morning rush hour - with a vehicle that can swap traffic queues for river cruises.

John Hinton Shortcutter John Hinton models his amphibious mower/boat combo (Pic: M and Y)
John’s ‘Shortcutter’, made from a sit-on lawnmower and an old boat, can chug along the roads at a ‘relaxing’ 9kph (6mph), then take to the water at the first sign of a snarl-up.
Of course, with a top speed that could cause more traffic jams than it solves and a propeller that spins wildly behind it on dry land, the four-wheeler is still very much a work in progress.
John Hinton, Shortcutter Land ahoy: John hits the road (Pic: M and Y)
But Mr Hinton hopes future models could revolutionise the way we travel.
The 76-year-old said: ‘In theory, you could go anywhere on it – it would be just as good as a normal car.
John Hinton, Shortcutter Take the wheel: Inside the vehicle (Pic: M and Y)

‘You could go and get your shopping on it or go to work in it and, if you had to cross a lake or river or even part of the sea to get there, that would be fine.
‘If it was big enough you could probably get all the way to France, drive on to land, pick up some cheese and wine and bring it all back without leaving the boat.’

John Hinton, Shortcutter The lawnmower before conversion (Pic: M and Y)

A YouTube video of Mr Hinton’s invention has attracted bemused interest since he uploaded it two months ago.

And the retired insurance broker, of Horsham in West Sussex, has even been in touch with Honda about mass production of his vehicle.
He added: ‘It’s about time the car and marine industries combined.’
Mr Hinton spent two years and £1,000 making the prototype with late friend Laurie Mayhead.
Wife Pat said: ‘Everyone needs something to do when they retire. This is just one of his many projects. I was quite happy to get him out of the house, to be honest.’

Much mystery surrounded the electric versions of the Fiat 500 that have appeared at auto shows over the last year.
Now, Chrysler has cleared up a bit of the confusion: It will build an electric Fiat 500 for the U.S. market, with a powertrain developed by engineers at its Michigan headquarters, at a price that's "competitive with similar electric vehicles in the market."

The Fiat 500 EV will go into production in 2012, perhaps as a 2013 model. By that time, electric cars on the market will include the 2010 Tesla Roadster, 2011 Nissan Leaf, 2011 Coda Sedan, 2011 Chevrolet Volt, 2011 Fisker Karma, and 2012 Toyota Prius Plug-In Hybrid.
According to a Chrysler spokesman, the specifications of the 500 BEV concept shown at auto shows should not be viewed as reflective of a production vehicle.
While Nick Cappa, a Chrysler PR manager for technology, offered no details on technology, energy storage, power, performance, range, or timing, he acknowledged two marginally interesting points.
It would be "safe to assume," he said, both that the engine-less Fiat 500 vehicles to be converted to electric drive might be built at the Mexico plant where standard 500s will be manufactured.
Observers might also assume, he said, that lithium-ion cell maker A123 Systems--with whom Chrysler has said it is working--might be involved in designing the battery pack that will be used in the electric 500.
Cappa's most revealing comment came in describing the potential buyers of a Fiat 500 EV: "daily commuters who don't travel more than 40 miles a day"--though he hastened to add that the 500 EV would have a range "well beyond that" and be highway capable.
Like most pure electric vehicles going into production, the electric Fiat is on the small side. "The Fiat 500 is a small, lightweight platform perfect for integrating electric-vehicle technology," said Scott Kunselman, Chrysler Group's senior vice president of engineering.
The conventional gasoline-powered 2011 Fiat 500 will go on sale at selected Chrysler dealers in the U.S. before the end of this year. While EPA ratings haven't yet been issued, we'd expect it to be on a par with the 2010 Mini Cooper, at 28 mpg city, 37 mpg highway.
Despite various pre-bankruptcy promises and pledges, the Fiat 500 EV is the first electric car Chrysler has announced it will build, because electric cars have gained a far higher profile lately. "They're not just important," Cappa said. "They're necessary."

Michigan Readies as the U.S. Prepares for Electric Vehicles

More than 5,300 home and workplace charging stations to be installed in Michigan

2010-10-13


DETROIT – More than 5,300 home and workplace charging stations are planned to be installed in Michigan as the state prepares for the introduction of new electric vehicle technology. General Motors and its partners are teaming up to help give Chevrolet Volt buyers more options for charging their vehicles.
DTE Energy pledges to install 2,500 240V home charging stations for plug-in vehicles, and Consumers Energy is matching that pledge.  The utilities will cover up to $2,500 of the cost of the charging station and installation. GM's Voltec 240 V home charging station is priced at just $490 plus an estimated $1,475 for installation.  The city of Lansing Board of Water and Light will provide an additional 25 charging stations to its customers and by the end of 2011, General Motors plans to have almost 350 charging stations in place for employees at its facilities in Michigan, with more than 100 already installed.
In addition, more than 1,500 Chevrolet dealers across the U.S. plan to install charging stations for use by customers. This number includes nearly 650 dealers that will soon begin selling the Volt in retail launch markets and approximately 900 others across the country that are authorized to provide service.
More important than the total volume of charging stations is where they will be located, according to Tom Stephens, GM vice chairman, Global Product Operations. “Since our homes may soon be our fueling stations of the future we believe the most important way to make communities 'plug-in ready' is by enabling residential charging.”
Most of these stations will be placed in consumers’ garages, carports and driveways.  A few will be strategically located, such as the two GM placed in front of its headquarters at the Renaissance Center at the building’s entrance off of Jefferson Ave in Detroit.  A total of 18 charging stations will be operational in and around the Renaissance Center within the next week.
“We think this opens up doors for those Volt owners who want to charge at work or who don’t have a place at home to charge the car overnight.  They’ll be able to drive electrically when they can, and they can drive on gasoline when they need to,” Stephens said in remarks at the Business of Plugging In Conference in Detroit on Tuesday.  “We see these stations as an incentive to our employees to join the Electric Vehicle movement … and as a demonstration to other businesses to encourage their own employees to drive greener.”
GM-installed charging stations for use by its employees in Michigan will include 34 at the Detroit-Hamtramck assembly center where the Volt is built and 140 in the homes of employees driving early-build models for quality evaluation.
Many of the stations at GM facilities will be powered by renewable solar energy. The Detroit-Hamtramck assembly center already has 10 stations in place powered by photovoltaic systems from SunLogics Inc. Envision Solar International (OTCBB:EVSI) will provide its innovative Solar Tree® with EnvisionTrak™ system  for use at the Warren Technical Center and Milford Proving Ground. 
GM envisioned the need for public and workplace charging stations in 2007 when it formed a collaboration with DTE, Consumers Energy, the Electric Power Research Institute and more than 50 other utilities. Many of those utilities are or will be launching similar programs to help customers prepare for electrification.
Michigan is one of nine regions in the United States identified by the U.S. Department of Energy to lead the electrification movement.  Free home charging stations provided by ECOtality and Coulomb Technologies will be available to 4,400 eligible Volt owners through a program funded by the DOE.
“We’ve put a lot of thought into the best way to enhance the electric vehicle experience,” Stephens said.  “We’ve focused on everything from vehicle-to-grid technical interfaces, codes and standards to leading consumer education and outreach.”
In fact, the Society of Engineers-approved industry standard for charging equipment was led by a GM engineer. And GM’s Opel subsidiary recently announced a vehicle-to-grid experiment in Germany involving a battery electric version of the Opel Meriva.
About General Motors – General Motors, one of the world’s largest automakers, traces its roots back to 1908.  With its global headquarters in Detroit, GM employs 208,000 people in every major region of the world and does business in more than 120 countries.  GM and its strategic partners produce cars and trucks in 31 countries, and sell and service these vehicles through the following brands:  Buick, Cadillac, Chevrolet, FAW, GMC, Daewoo, Holden, Jiefang, Opel, Vauxhall and Wuling.  GM’s largest national market is China, followed by the United States, Brazil, Germany, the United Kingdom, Canada, and Italy.  GM’s OnStar subsidiary is the industry leader in vehicle safety, security and information services.  General Motors acquired operations from General Motors Corporation on July 10, 2009, and references to prior periods in this and other press materials refer to operations of the old General Motors Corporation.  More information on the new General Motors can be found at www.gm.com.

Zero Emission Solar Charging At Chevrolet Volt Plant [Video]

http://www.allcarselectric.com/blog/1051887_zero-emission-solar-charging-at-chevrolet-volt-plant-video



November 24th, 2010 We've discussed before the issue of how clean electric cars really are when you take into consideration the source of the electricity you use to charge them - they're only as clean as the grid powering them. It's usually one of the first things EV dissenters bring up... "Yeah, but where does the electricity come from, hmm? Coal power?" at which point many of us are ready to hit them back with "Yeah, but where does the gasoline come from, hmm?" before explaining the massive chain of production for fossil fuels. POW! One-nil to the electric car. Chevrolet can bypass that conversation altogether though with their new solar-powered recharging station at the Detroit-Hamtramck Volt assembly plant. Twelve charging points are situated under an 18.2 kW solar array from which the stations draw their power. Dave Schuster, manufacturing and engineering manager at Detroit-Hamtramck, says that up to 10 Volts can be charged at once. Even on the cloudy day featured in the video, the station managed to capture 3 kWh of electricity, and on a sunny day Schuster claims they can charge six Volts all at once from the power generated. The charging stations themselves are 240-volt devices (or a 'level 2' charger) which should allow a full charge in 3 to 4 hours, compared to the 8-10 hours a regular 120V socket would allow for. The more exciting news is the 7-acre array that Chevrolet have planned which will help power the plant itself, meaning even Volt production will be greener.

Eesmärk: suurendada taastuvenergia osakaalu 25 protsendini

http://teadus.err.ee/artikkel?id=3106&cat=1

Valitsus kinnitas täna Eesti taastuvenergia tegevuskava aastani 2020, mille kohaselt moodustab taastuvenergia osakaal aastaks 2020 vähemalt veerandi kogu siseriiklikust energiatarbimisest. Oluliseks ülesandeks on taastuvate energiaallikate osakaalu suurendamine elektriturul. Kava kohaselt saavutab riik taastuvate energiaallikate abil toodetud elektri osaks tarbimises üle 15 protsendi.

Majandus- ja kommunikatsiooniminister Juhan Partsi sõnul tuleb taastuvenergia kasutamise mahtu kõige rohkem suurendada transpordis ja elektri tootmisel. "Taastuvenergia tegevuskava  on teekaart järgmiseks kümneks aastaks, et täita Eestile võetud kohustused Euroopa Liidu ees," lisas Parts.

Tegevuskava näeb ette tuuleelektri  võimsuse järk-järgulist kasvu praeguselt 150 megavatilt ligikaudu 600 megavatini aastaks 2020. Samuti tuleb laiendada suuremates linnades elektri tootmist taastuvaid energiaallikaid ja muid kohalikke kütuseid kasutavates koostootmisjaamades. Hüdroenergia täiendav kasutuselevõtt on tagasihoidlikum.

"Kuna taastuvenergia osakaal järjest suureneb, siis on eriti oluline see, et teisalt väheneksid tootjatele makstavad liigsuured toetused," rääkis Parts. "Me püüdleme puhtama keskkonna poole, aga see  ei tohi olla tarbijale üle mõistuse kallis," sõnas ta.

Maismaatranspordis on eesmärk saavutada taastuvenergia osakaaluks 10 protsenti kasutatud energiaallikatest. See tähendab, et aastal 2020 tuleks autotranspordis kasutada ligikaudu 90 000 tonni biokütuseid. Transpordis biokütuste osakaalu eesmärgi saavutamiseks tuleb edendada ka elektrisõidukite kasutuselevõttu.

Taastuvenergia tegevuskava vähendab Eesti sõltuvust imporditavatest kütustest ning parandab Eesti väliskaubandusbilanssi. Biokütuste suurem kasutus loob uusi töökohti ja parandab sellega tööhõivet, eriti maapiirkondades, luues sellega eeldused maapiirkondade arenguks.

Euroopa Liidu poolt seatud Eesti vahe-eesmärk aastaks 2011 on saavutada taastuvenergia osakaaluks 19,4 protsenti. Prognooside kohaselt peaks Eestis taastuvenergia osa selleks ajaks olema aga juba 21,5 protsenti.

Making Silent Electric Cars Noisier: 3 Carmakers, 3 Sounds

Making Silent Electric Cars Noisier: 3 Carmakers, 3 Sounds


November 23rd, 2010 It looks like carmakers are going to make their quiet, electrically powered cars a lot noisier. And that's going to happen regardless of whether there's any actual data to support the notion that electric cars are so silent they pose a hazard to blind pedestrians. As of now, three different automakers have taken three different approaches, with more likely to be on the way in future models. Warbles, blips, or fake engine noises? The 2011 Nissan Leaf electric car automatically makes a kind of futuristic electronic warbling sound up to 12 miles per hour. Beyond that speed, tire noise suffices, said Mark Perry, Nissan North America's director for product planning and advanced technology. The 2011 Chevrolet Volt extended-range electric vehicle, on the other hand, uses a driver-actuated alert system on the left column stalk that blips the horn several times quickly. GM worked with the National Federation of the Blind on that pedestrian warning device. Now, the new 2011 Kia Optima Hybrid introduced at last week's 2010 Los Angeles Auto Show adds a third variation: a straight-out synthesized engine noise that kicks in whenever the car is running in all-electric mode at 12 mph or below. Making your hybrid a spaceship A much greater variety of options is offered by the HALOsonic External Electronic Sound Synthesis system, prototyped by Lotus Engineering but not yet implemented in any production vehicles. It can produce a range of different noises for drivers to select among, from a droning buzz to the simulated exhaust sounds of a variety of virtual engines. Among the possibilities are a couple of noises that make a Toyota Prius hybrid sound like a spaceship. Which we much prefer to fake engine sounds. Thus far, Japanese colussus Toyota hasn't weighed in with a noise-making technology. That company has built and sold roughly two-thirds of the hybrid-electric vehicles on the planet today, so whatever solution it chooses will carry major weight--strictly on volume. Flawed legislation? Legislation appears to be on the way nonetheless. Section 109 of the proposed Motor Safety Act of 2010--now in front of the U.S. Senate's Commerce, Science, and Transportation Committee--includes provisions to require "new electric or hybrid vehicles to provide an alert sound” at less than 20 mph. There are at least two flaws here. First, the laws don't even try to define the problem--danger from quiet vehicles--objectively, perhaps via perceived decibel levels at specific distances. And, second, it ignores any hazards posed by quiet gasoline cars, by singling out just two types of vehicles (hybrids and electrics) that it deems dangerous.
