Plugging into the future: A Car Charging Infrastructure Takes Shape

Having shipped hundreds of electric vehicle charging stations, and with repeat orders now coming in from Europe, Coulomb Technologies, a privately-held Silicon Valley company, expects to be profitable by the 2010 introduction of the Chevy Volt, according to its chief executive, Richard Lowenthal.

(Mr. Lowenthal appears in the video above, explaining the company’s ChargePoint Network.)

“Our plan was to sell a thousand stations, but we will probably double that,” he told NY Times’ Green Inc. last week after the company secured its third Bay Area order this year. “Our company is structured to be profitable based on early adapters.”

Founded in 2007, Coulomb is looking to crack the chicken-and-egg riddle that bedeviled the hydrogen fuel cell industry. Without a refueling infrastructure, consumers won’t buy vehicles. But no one invested in refueling stations without potential customers on the road.

“It is a very fundamental issue for the business,” Mr. Lowenthal said. “What do you do about the road trip?”

With electric vehicles, the additional problem is that in cities like San Francisco, where almost half of all vehicles park on the city’s streets, many potential buyers couldn’t recharge their cars overnight.

Mr. Lowenthal, a Cisco veteran who served as mayor of Cupertino, said that municipalities, parking companies and condo developers represent the first tranche of customers for charge points that will be deployed on city streets and in garages. They sell for $2,500 to $4,000 and can recharge an electric vehicle battery in four to ten hours.

In what might shape up to be the VHS/Betamax duel of the industry, a Coulomb rival, Better Place of Palo Alto, is looking to develop refueling stations where consumers on road trips can swap batteries in a matter of minutes. Still other companies are building rapid recharge points.

Mr. Lowenthal predicted the next three years would define the nascent charging station industry. By 2012, he said, the car industry will have an understanding of the early adoption rate for electric vehicles and plug-in hybrid electric vehicles.

Zipcar News: Zipcar founder tinkers with ridesharing and social networking tools; Zipcar’s iPhone App Makes Car-Sharing A Breeze

June 15, 2009 at 11:22 am

(Source: Urban Omnibus, Wired)

Urban Omnibus and The Infrastructurist talk to the founder of Zipcar and GoLoco about everything from mesh networks to taxi stands to why “infrastructure is destiny.”  In this exhaustive interview published on the Urban Omnibus, you can get to read about Robin’s new social networking project that aims to turn your social network into a travel network. The last couple years she’s been working on GoLoco, which aims to do for ride sharing what Zipcar did for car sharing: to make it easy, efficient and commonplace to share car travel, split costs, and reduce emissions. GoLoco members receive alerts when one of their friends or interest groups is going whether they want to.  Here is an interesting excerpt from the interview, that offers a better understanding of how GoLoco works.

So, as you have moved from Zipcar to GoLoco, from car sharing to ride sharing, do you see ride sharing as more of a national set of strategies?
Yes, car sharing only works in dense metropolitan areas or in cases where people don’t need a car to get to work. If you need a car to get to work, you’re going to have to own your own car. The cost of car sharing is too high for a daily commute. But, then again, according to the National Households Consumer Survey, across the nation it costs $24 per day on average that people are spending in America on their car, day in and day out. If I were to tell you that it was going to cost $125 a week to go to work, you would say, no way, I’m not going to do it. But we are doing it – we just don’t realize we’re doing it.

That’s why I did GoLoco – I said, what about all those other people who are feeling similar transportation and mobility pains but they need a car to get to work? Ride sharing is for those people.

Can you give us ride sharing 101? How can GoLoco change how we get around?

The big idea for ride sharing and for GoLoco is to think of your car, your expenses, your friends, and your trips as part of your own personal public transportation system. Your friends and their cars and their trips are ways that you can get around. It builds on the idea of long tail media and long tail economics. Ride sharing is the long tail of public transportation. There are rides that serve little niches of demand way out there, in places where you’ll never see a bus service, or a public transportation service of any kind, but you would see ride sharing, because of the individuals who do go way out there. Basically, if you look at the long tail, ride sharing can meet the needs of small groups of individuals who need to get from a specific origin to a specific destination at a particular time.

I think when we look back at ourselves sitting alone in our 120 square feet of car, driving down these highways with incredible storage costs and incredible operating costs, I think we will look back at how we travel today and be just astounded: astounded at the cost, astounded at the waste. It’s such a wacky idea that we’d want to be alone in our cars spending huge sums of money and all that parking space, when it was less fun and more expensive and kind of crazy.

This is why I did GoLoco. We know that we can’t build our way out of congestion, so if things are increasingly, year after year, getting more congested, there’s only one solution for that: addressing the cost of driving over peak periods.

At $2 per gallon, people spend 18% of their income on their car, and that’s without paying for congestion pricing or tax increases or any other changes to transportation financing coming down the road. But it’s not in the control of any government to effect what the ultimate price of gas is going to be when we have increasing demand from India and China, and arguably peak oil. We have an increasing world population that will continue to drive cars with gasoline on our roads. Ride sharing is going to be significant while we transform our infrastructure to be less car-dependent. While we have such a high cost of car travel in such a car-dependent country, I don’t see another solution. 86% of trips made are alone in a car. Think about standing in a mall, looking at a parking lot. You know that a large number of people there are going exactly where you’re going in the next five minutes.

In other related ZipCar news,  there is a new iPhone App from Zipcar which makes car sharing a breeze.  The pioneering car-share company has developed an iPhone app you can use to choose, reserve and locate a car on the go – a brilliant move, considering one-quarter of the company’s subscribers have an iPhone in their pocket.

The app tells you what cars are available and uses GPS and Google Maps to direct you to it once you’ve made a reservation. Should the car you’re looking for be lost in a sea of cars in a parking lot, the app will help you find it by sounding the car’s horn. That’s also handy for finding your ride if you’ve forgotten where you’ve parked it.  Zipcar is the largest car-sharing service in the world, with locations in 49 U.S. cities in addition to Vancouver, Toronto and London. The company believes the app, which will be available later this summer, will allow it to expand its service and make car-sharing a breeze.

“There are currently 15 million people within a block of a Zipcar service station and about 47 million iPhone customers,” says Luke Schneider, Zipcar’s chief technology officer. “We therefore estimate that our car sharing network could potentially increase to 32 million customers in years to come as a result of our new partnership and expansion into new markets.”

GAO Report on Aviation and Climate Change Says Aircraft Emissions Expected to Grow, but Technological and Operational Improvements and Government Policies Can Help Control Emissions

June 13, 2009 at 10:05 am

(Source:  Government Accountability Office)

Aircraft emit greenhouse gases and other emissions, contributing to increasing concentrations of such gases in the atmosphere. Many scientists and the Intergovernmental Panel on Climate Change (IPCC)–a United Nations organization that assesses scientific, technical, and economic information on climate change–believe these gases may negatively affect the earth’s climate. Given forecasts of growth in aviation emissions, some governments are taking steps to reduce emissions.

In response to a congressional request, GAO reviewed:

(1) estimates of aviation’s current and future contribution to greenhouse gas and other emissions that may affect climate change;

(2) existing and potential technological and operational improvements that can reduce aircraft emissions; and

(3) policy options for governments to help address commercial aircraft emissions.

GAO conducted a literature review; interviewed representatives of government agencies, industry and environmental organizations, airlines, and manufacturers, and interviewed and surveyed 18 experts in economics and aviation on improvements for reducing emissions from aircraft. GAO is not making recommendations. Relevant agencies provided technical comments which we incorporated as appropriate and EPA said emissions standards can have a positive benefit to cost ratio and be an important part of policy options to control emissions.

According to IPCC, aviation currently accounts for about 2 percent of human-generated global carbon dioxide emissions, the most significant greenhouse gas–and about 3 percent of the potential warming effect of global emissions that can affect the earth’s climate, including carbon dioxide. IPCC’s medium-range estimate forecasts that by 2050 the global aviation industry, including aircraft emissions, will emit about 3 percent of global carbon dioxide emissions and about 5 percent of the potential warming effect of all global human-generated emissions. Gross domestic product growth is the primary driver in IPCC’s forecasts. IPCC also made other assumptions about future aircraft fuel efficiency, improvements in air traffic management, and airport and runway capacity. IPCC’s 2050 forecasts for aviation’s contribution to global emissions assumed that emissions from other sectors will continue to grow.

If other sectors make progress in reducing emissions and aviation emissions continue to grow, aviation’s relative contribution may be greater than IPCC estimated; on the other hand, if other sectors do not make progress, aviation’s relative contribution may be smaller than estimated. While airlines currently rely on a range of improvements, such as fuel-efficient engines, to reduce emissions, some of which may have limited potential to generate future reductions, experts we surveyed expect a number of additional technological, operational, and alternative fuel improvements to help reduce aircraft emissions in the future. However, according to experts we interviewed, some technologies, such as advanced airframes, have potential, but may be years away from being available, and developing and adopting them is likely to be costly.

In addition, according to some experts we interviewed, incentives for industry to research and adopt low-emissions technologies will be dependent to some extent on the level and stability of fuel prices. Finally, given expected growth of commercial aviation as forecasted by IPCC, even if many of these improvements are adopted, it appears unlikely they would greatly reduce emissions by 2050. A number of policy options to address aircraft emissions are available to governments and can be part of broader policies to address emissions from many sources including aircraft. Market-based measures can establish a price for emissions and provide incentives to airlines and consumers to reduce emissions. These measures can be preferable to other options because they would generally be more economically efficient. Such measures include a cap-and-trade program, in which government places a limit on emissions from regulated sources, provides them with allowances for emissions, and establishes a market for them to trade emissions allowances with one another, and a tax on emissions. Governments can establish emissions standards for aircraft or engines. In addition, government could increase government research and development to encourage development of low-emissions improvements.

California notches another world 1st in its environmental campaign – This time with a plug-in oceanliner!

June 12, 2009 at 2:44 pm

(Source: Revenge of the Electric Car & LA Times)

It’s been a long time coming, but we have finally achieved the first “cold ironing” of a tanker in the Port of Long Beach. Cold Ironing is the term for plugging a ship’s electrical system into the on-shore grid to supply power so that the ship’s giant diesel engine can be turned off while it’s docked. Normally, these engines crank out massive amounts of pollution, equal to “a day’s worth of driving by 187,000 cars,” according to estimates by the Port of Long Beach.

Port of Long Beach takes ‘giant step’ toward pollution reduction Port officials unveil what is billed as the world’s first electrical shore-side power system for tankers, which are notorious fuel guzzlers and air polluters.  Docked in Long Beach on Wednesday with a fresh load of oil from Valdez, the Alaskan Navigator didn’t look like much of a trailblazer.

The massive tanker sat silently, with a few thin cables draping down to some gray metal boxes. Missing was the incessant rumble of diesel engines, which on an average cargo ship would be running constantly to keep electrical systems going — burning quite a bit of diesel fuel and generating a significant amount of pollution. But the 941-foot Navigator, anchored at the BP oil terminal’s Pier T on the Long Beach port’s main channel, isn’t average. The vessel, owned by Alaska Tanker Co. of Portland, Ore., was plugged into what is billed as the world’s first shore-side electrical grid.

The project cost $23.7 million and took three years to complete, port officials said. The port contributed about $17.5 million to the project and BP paid the rest.  One project partner noted that the emissions reductions amounted to 50% even when factoring in pollution created by power plants in generating the electricity.

The Natural Resources Defense Council (NRDC) initiated suits against the ports over seven years ago to make this happen, and it was a long difficult fight, but the NRDC’s attorneys persevered and eventually won. This event marks the first of what we hope will be the electrification of all the tanker and cargo ships while docked in the ports of Los Angeles and Long Beach (and probably worldwide?). For too long, the people living downwind of the ports have suffered the ill effects of this pollution with heart and lung disease, cancers and asthma rates that are significantly higher than average.

Toxic battle brewing over a new breed of automobile refrigerant HFO-1234yf; Greenpeace Germany sounds alarm; German Environment Minister calls it “highly risky economic and technical adventure”

June 12, 2009 at 2:07 pm

(Source: R744.com &1234facts.com)

In a letter sent to German OEMs on 27 May, Greenpeace Germany is attacking the global car industry for deliberately or recklessly downplaying the formation of highly toxic hydrogen fluoride from HFO-1234yf by several magnitudes. A review of a SAE scientific paper supported by global OEMs revealed that at the correct rate of HF concentration “all passengers would die with close to certainty”.

The manufacturers are touting that HFO-1234yf meets the automotive industry’s needs for a cost-effective, commercially viable low global warming potential (GWP) replacement for R-134a refrigerant.

Some of the stated benefits of HFO-1234yf include:

  • lower lifetime greenhouse gas emissions
  • dramatically shorter atmospheric lifetime
  • compatibility with current automotive a/c systems
  • superior cooling efficiency
  • best ease of adoption
  • safety for mobile applications

In the early 1900’s, CFCs provided the first form of refrigeration. As their ozone-depleting potential became recognized, the Montreal Protocol was adopted by many nations to begin the phase out of both CFCs and HCFCs. HFCs were developed to fill the void and while they were non-ozone depleting, they did have global warming potential.

“It is unknown to us if this is a factual error or if there are manipulative intentions behind this misinformation. Fact is, however, that the (correct) rate of HF concentration from the refrigerant 1234yf in a passenger compartment will not be around 150 ppm (depending on the vehicle) but will be a multitude of that. At these concentrations all passengers will die with close to certainty,” the Greenpeace letter, sent to the boards of all car manufacturers united in the VDA on 27 May, reads.
“As a result, the claim that 1234yf will be an alternative is not only wrong but also life threatening; the legal consequences not calculable,” the letter continues before calling on all carmakers to point out this dangerous misinformation in the automotive industry and correct the calculation.

Greenpeace refers to a peer-reviewed SAE Paper presented by Roberto Monforte, Fiat, at the SAE World Congress in Detroit on 21 April. The paper, obtained by R744.com, states that if 0.55 kg of HFO-1234yf are completely released in an accident and exposed to a flame inside the passenger compartment of a Pontiac Grand Prix model the concentration of highly toxic hydrogen fluoride will not surpass 150 ppm (parts per million). HFO-1234yf would therefore not pose a higher risk to the passenger than the currently used refrigerant R134a.

A calculation strongly rejected by Greenpeace and external industry sources, who suggest that this figure might be understating the actual formation of HF by up to 1000 times. If 0.55 kg of 1234yf are burned, 0.39 kg of HF will develop. Calculated on a cabin volume of 3m3 (weight of air 3.6 kg), a concentration of 100,000 ppm would occur, or 10.7%. As opposed to 150 ppm, this 1000 times higher concentration would be enough to kill busloads of humans. Even with varying vehicle types, the HF rate inside the compartment could be hundreds of times higher than that assumed in the SAE paper. Click here to read more about the Greenpeace argument.

In the middle of this fiasco, Environment Minister Sigmar Gabriel has raised his voice to warn the German automotive industry against a “highly risky economic and technical adventure” with an untested, flammable, and toxic refrigerant 1234yf. Moreover, manufacturers should not expect the EU R134a phase-out schedule to change, but rather choose CO2 now as the most energy-efficient and safe alternative available.

German Environment Minister: Untested 1234yf an “adventure”In an interview with ACE, a leading automotive club representing the interests of 550.000 Germans, the Environment Minister Sigmar Gabriel has taken a clear stance in favour of CO2 in the currently hotly debated question of which refrigerant to choose for future car air conditioning systems:

“Fact is: With CO2 there is an environmentally friendly alternative to R134a available, and it has been proven in real life,” Gabriel stated. “The VDA has to know what it does to strengthen its credibility or not,” he referred to the clear commitment to CO2 already issued in 2007 by all carmakers united in Germany’s automotive association VDA. The Environment Ministry would continue to support CO2 (R744) as not only the most ecological option, but also that with a significantly higher energy efficiency, as measurements by the Federal Environment Agency have proved.

Untested chemical “high adventure”
Gabriel also issued a clear warning to the automotive industry to not use untested alternative refrigerants. The currently discussed flammable and toxic chemical 1234yf would be a completely new substance not yet fully investigated by public authorities for its ecological and health risks. As a consequence, manufacturers deciding for 1234yf would embark on a “high economic and technical adventure”, Gabriel concluded.

The Minister warned the German automotive industry against a further use of R134a in cars after 2011. According to Gabriel, the EU MAC Directive, prescribing the use of refrigerants with a Global Warming Potential of below 150 in future passenger cars, will not be changed. Carmakers should acknowledge that he would hold on to the agreed phase-out schedule starting in 2011, with a gradual ban of R134a until 2017. As a result, from 2011, the deprivation of type approval for cars using the climate-damaging refrigerant would be enforced as originally scheduled.

Volvo Technology to Lead New York Commercial Vehicle Infrastructure Integration Development Program

June 11, 2009 at 11:27 pm

(Source: Green Car Congress)

The New York State Department of Transportation (NYSDOT) has selected Volvo Technology North America to lead the development and demonstration of an advanced Commercial Vehicle Infrastructure Integration (CVII) program. A contract awarding this program to Volvo Technology is being finalized by the state.

The program will demonstrate VII applications for commercial vehicles along key transportation corridors in the greater New York City region. Test corridors, utilizing 5.9 GHz dedicated short range communications (DSRC), include 13 miles of the New York State Thruway Authority’s I-87 Spring Valley Corridor and 42 miles of NYSDOT’s I-495 Long Island Expressway.

VII is an advanced ITS (Intelligent Transportation System) technology using infrastructure similar to that of 915 MHz based systems such as E-Z PASS but with the capability of very high-speed, high-capacity data communication using an on-board communication device that is integrated with the electronic information and control systems of the vehicle.

Visual and audible information is available to the driver from the VII network, and the vehicle can communicate information to the VII roadside infrastructure as well as other vehicles, creating smart vehicles operating along a smart highway and transportation system, NYSDOT notes.

VII development has focused almost exclusively on passenger vehicles. While a number of major light vehicle manufacturers have been directly involved with the VII technology development under the leadership of the USDOT, the commercial vehicle industry has not been sufficiently represented, NYSDOT said. The Volvo-led effort for the state of New York, funded by the I-95 Corridor Coalition in cooperation with the Federal Highway Administration, is the first VII program exclusively devoted to developing and demonstrating the technology for commercial vehicles.

The Volvo-led program will test enhanced vehicle security, demonstrating driver identification and verification using TWIC (Transportation Worker Identification Credential, an identity card issued by the Transportation Security Administration) and biometric readers to restrict vehicle operation to authorized drivers only. The program will also test the ability to gather real-time information about important vehicle safety components, such as brake condition.

The goal of national Vehicle Infrastructure Integration (VII), which uses high speed, high capacity wireless technology, is to enhance highway user safety by allowing smart vehicles and highway infrastructure to communicate information to the driver. VII technology can provide a wide range of communications to the driver including safety warning of potential hazards and general traveler information.

For commercial vehicles, such high-speed, wireless communications can also be used to improve vehicle productivity and contribute to improved fuel efficiency and reduced CO2 emissions.

GAO says Plug-in Vehicles Offer Potential Benefits, but High Costs and Limited Information Could Hinder Integration into the Federal Fleet

June 11, 2009 at 5:32 pm

(Source: U.S. Government Accountability Office)

The U.S. transportation sector relies almost exclusively on oil; as a result, it causes about a third of the nation’s greenhouse gas emissions. Advanced technology vehicles powered by alternative fuels, such as electricity and ethanol, are one way to reduce oil consumption. The federal government set a goal for federal agencies to use plug-in hybrid electric vehicles–vehicles that run on both gasoline and batteries charged by connecting a plug into an electric power source–as they become available at a reasonable cost. This goal is on top of other requirements agencies must meet for conserving energy.

In response to a request, GAO examined the:

(1) potential benefits of plug-ins,

(2) factors affecting the availability of plug-ins, and

(3) challenges to incorporating plug-ins into the federal fleet. GAO reviewed literature on plug-ins, federal legislation, and agency policies and interviewed federal officials, experts, and industry stakeholders, including auto and battery manufacturers.

Increasing the use of plug-ins could result in environmental and other benefits, but realizing these benefits depends on several factors. Because plug-ins are powered at least in part by electricity, they could significantly reduce oil consumption and associated greenhouse gas emissions. For plug-ins to realize their full potential, electricity would need to be generated from lower-emission fuels such as nuclear and renewable energy rather than the fossil fuels–coal and natural gas–used most often to generate electricity today. However, new nuclear plants and renewable energy sources can be controversial and expensive. In addition, research suggests that for plug-ins to be cost-effective relative to gasoline vehicles the price of batteries must come down significantly and gasoline prices must be high relative to electricity.

Auto manufacturers plan to introduce a range of plug-in models over the next 6 years, but several factors could delay widespread availability and affect the extent to which consumers are willing to purchase plug-ins. For example, limited battery manufacturing, relatively low gasoline prices, and declining vehicle sales could delay availability and discourage consumers. Other factors may emerge over the longer term if the use of plug-ins increases, including managing the impact on the electrical grid (the network linking the generation, transmission, and distribution of electricity) and increasing consumer access to public charging infrastructure needed to charge the vehicles.

The federal government has supported plug-in-related research and initiated new programs to encourage manufacturing. Experts also identified options for providing additional federal support. To incorporate plug-ins into the federal fleet, agencies will face challenges related to cost, availability, planning, and federal requirements. Plug-ins are expected to have high upfront costs when they are first introduced. However, they could become comparable to gasoline vehicles over the life of ownership if certain factors change, such as a decrease in the cost of batteries and an increase in gasoline prices.

Agencies vary in the extent to which they use life-cycle costing when evaluating which vehicle to purchase. Agencies also may find that plug-ins are not available to them, especially when the vehicles are initially introduced because the number available to the government may be limited. In addition, agencies have not made plans to incorporate plug-ins due to uncertainties about vehicle cost, performance, and infrastructure needs.

Finally, agencies must meet a number of requirements covering energy use and vehicle acquisition–such as acquiring alternative fuel vehicles and reducing facility energy and petroleum consumption–but these sometimes conflict with one another. For example, plugging vehicles into federal facilities could reduce petroleum consumption but increase facility energy use. The federal government has not yet provided information to agencies on how to set priorities for these requirements or leverage different types of vehicles to do so. Without such information, agencies face challenges in making decisions about acquiring plug-ins that will meet the requirements, as well as maximize plug-ins’ potential benefits and minimize costs.

The recommendations are listed below:

  • To enable agencies to more effectively meet congressional requirements, the Secretary of Energy should, in consultation with Environmental Protection Agency (EPA), General Services Administration (GSA), Office of Management and Budget (OMB), and organizations representing federal fleet customers such as Interagency Committee for Alternative Fuels and Low-Emission Vehicles (INTERFUEL), Federal Fleet Policy Council (FEDFLEET), and the Motor Vehicle Executive Council, propose legislative changes that would resolve the conflicts and set priorities for the multiple requirements and goals with respect to reducing petroleum consumption, reducing emissions, managing costs, and acquiring advanced technology vehicles.
  • The Secretary of Energy should begin to develop guidance for when agencies consider acquiring plug-in vehicles, as well as guidance specifying the elements that agencies should include in their plans for acquiring the mix of vehicles that will best enable them to meet their requirements and goals. Such guidance might include assessing the need for installing charging infrastructure and identifying areas where improvements may be necessary, mapping current driving patterns, and determining the energy sources used to generate electricity in an area.
  • The Secretary of Energy should continue ongoing efforts to develop guidance for agencies on how electricity used to charge plug-ins should be measured and accounted for in meeting energy-reduction goals related to federal facilities and alternative fuel consumption. In doing so, the Secretary should determine whether changes to existing legislation will be needed to ensure there is no conflict between using electricity to charge vehicles and requirements to reduce the energy intensity of federal facilities, and advise Congress accordingly.
  • The Administrator of GSA should consider providing information to agencies regarding total cost of ownership or life-cycle cost for vehicles in the same class. For plug-in vehicles that are newly offered, the Administrator should provide guidance for how agencies should address uncertainties about the vehicles’ future performance in estimating the life-cycle costs of plug-ins, so agencies can make better-informed, consistent, and cost-effective decisions in acquiring vehicles.
  • Once plug-in hybrids and all-electrics become available to the federal government but are still in the early phases of commercialization, the Administrator of GSA should explore the possibility of arranging pass-through leases of plug-in vehicles directly from vehicle manufacturers or dealers–as is being done with DOD’s acquisition of neighborhood electric vehicles–if doing so proves to be a cost-effective means of reducing some of the risk agencies face associated with acquiring new technology.

Opting to take the train instead of driving for environmental reasons? Think twice about ‘green’ transport, say scientists

June 11, 2009 at 12:32 pm

(Source: AFP via Yahoo & Science Daily)

Image Courtesy: IOP - Energy consumption and GHG emissions per PKT (The vehicle operation components are shown with gray patterns. Other vehicle components are shown in shades of blue. Infrastructure components are shown in shades of red and orange. The fuel production component is shown in green. All components appear in the order they are shown in the legend.)

Do you worry a lot about the environment and do everything you can to reduce your carbon footprint? Are you the one who frets about  tailpipe emissions, greenhouse gases and climate change?

If yes,  you must be the one who prefers to take the train or the bus rather than a plane, and avoid using a car whenever you can, faithful to the belief that this inflicts less harm to the planet.

Well, there could be a nasty surprise in store for you, for taking public transport may not be as green as you automatically think, says a new US study published in Environmental Research Letters, a publication of Britain’s Institute of Physics.  Often unknown to the public, there are an array of hidden or displaced emissions that ramp up the simple “tailpipe” tally, which is based on how much carbon is spewed out by the fossil fuels used to make a trip. Environmental engineers Mikhail Chester and Arpad Horvath at theUniversity of California at Davis say that when these costs are included, a more complex and challenging picture emerges.

In some circumstances, for instance, it could be more eco-friendly to drive into a city — even in an SUV, the bete noire of green groups — rather than take a suburban train. It depends on seat occupancy and the underlying carbon cost of the mode of transport.

The pair give an example of how the use of oil, gas or coal to generate electricity to power trains can skew the picture.

Boston has a metro system with high energy efficiency. The trouble is, 82 percent of the energy to drive it comes from dirty fossil fuels.  By comparison, San Francisco‘s local railway is less energy-efficient than Boston’s. But it turns out to be rather greener, as only 49 percent of the electricity is derived from fossils.

The paper points out that the “tailpipe” quotient does not include emissions that come from building transport infrastructure — railways, airport terminals, roads and so on — nor the emissions that come from maintaining this infrastructure over its operational lifetime.

The researchers also touch on the effect of low passenger occupancy and show that we are naïve to automatically assume one form of transport is more environmentally friendly than another. They conclude from their calculations that a half-full Boston light railway is only as environmentally friendly, per kilometre traveled, as a midsize aircraft at 38 per cent occupancy.  From cataloguing the varied environmental costs the researchers come to some surprising conclusions. A comparison between light railways in both Boston and San Franciso show that despite Boston boasting a light railway with low operational energy use, their LRT is a far larger greenhouse gas (GHG) emitter because 82 per cent of the energy generated in Boston is fossil-fuel based, compared to only 49 per cent in San Francisco.

Total life-cycle energy inputs and GHG emissions contribute an additional 155 per cent for rail, 63 per cent for cars and buses, and 32 per cent for air systems over vehicle exhaust pipe operation.

So getting a complete view of the ultimate environmental cost of the type of transport, over its entire lifespan, should help decision-makers to make smarter investments.

For travelling distances up to, say, 1,000 kilometres (600 miles), “we can ask questions as to whether it’s better to invest in a long-distance railway, improving the air corridor or boosting car occupancy,” said Chester.  The calculations are based on US technology and lifestyles.

Ride of the Future? – ABC News Chief Washington Correspondent George Stephanopoulos Calls Coda EV the American Answer to Japanese Prius

June 10, 2009 at 7:20 pm

(Source: ABC News & Autobloggreen)

I had an opportunity to take a ride today in a new electric car that has perhaps one of the best shots at being the U.S. answer to Japan’s popular Toyota Prius.

Image Courtesy: Autobloggreen

Designed by Santa Monica, California-based Coda Automotive, the four-door sedan isn’t powered by gas. The electric battery can plug into any standard AC outlet.

Coda says a 40-mile commute takes about 2 hours to charge.

Right now, the car and it’s battery are manufactured in China. But the company has applied for tens of millions of dollars worth of stimulus funding through the Department of Energy to build an electric battery plant in a factory in Enfield, Connecticut to fuel it’s vehicles.

“The U.S. has zero,  absolutely no mass battery manufacturing in the United States.  So we’re going to China where they can mass produce the batteries to get these cars to market in the U.S. fast until we can get these produced here” said Kevin Czinger, president and CEO of Coda Automotive.

Coda plans to partner with aerospace battery designer Connecticut-based Yardney Technical Products to create and mass produce the first U.S. electric car battery.

The company says the plant could employ 600 people at first, and then possibly grow. Beginning next June, Coda plans to have the capacity to build 2,700 cars and 20,000 a year in 2011. By comparison, Toyota sold about 159,000second-generation Toyota Prius hybrid cars last year in the U.S.  The price tag? $45,000 — but buyers could receive a federal tax credit worth $7,500 and other state incentives that Coda says could drive the price down to $32,500.

Details, Details, Details: A quick comparision of the House vs. Senate forms of “Cash for Clunkers” a.k.a Consumer Assistance to Recycle and Save (CARS Act) bill

With the “Cash for Clunkers” bill successfully clearing the House floor, there is a lot of chatter about the fate of this bill in the Senate.   The auto industry and Michigan lawmakers are pushing for quick Senate action on this legislation to boost auto sales, after the House overwhelmingly passed the bill Tuesday.

But it remains unclear when Senate supporters may overcome the objections of Senate appropriators and a group of senators who say the House proposal doesn’t do enough to improve fuel efficiency on the nation’s highways.

The House approved its version Tuesday, 298-199, with substantial Republican support despite the opposition of House leaders including Minority Leader John Boehner and whip Eric Cantor.

Sens. Debbie Stabenow, D-Lansing, and Sam Brownback, R-Kan., introduced a nearly identical bill in the Senate, but had to withdraw an attempt to get a floor vote last week.

Opposition came from members of the Senate Appropriations Committee, which objected to funding provisions of the bill, and from senators who want tougher fuel economy requirements.

Sen. Diane Feinstein, D-Calif., introduced a competing proposal on Monday.   Feinstein’s proposal would require drivers to achieve a 25 percent fuel-efficiency increase before receiving a tax credit for ditching their clunkers. But Michigan Sen. Debbie Stabenow (D) is pushing for a trade-in tax credit that’s very similar to Sutton’s — truck owners would only have to increase their fuel efficiency by 2 miles per gallon to be eligible.  The requirements for car trade-ins aren’t much better under the Stabenow and Sutton plans, with a mere4 mpg increase in fuel economy triggering the $3,500 tax credit.  With Rep. Sutton’s plan winning the House approval this week, Stabenow’s Senate counterpart could potentially get a leg up over Feinstein’s.

Also, our friends at Jalopnik have compiled an awesome visual that simplifies the rs details of this “Cash for Clunkealong” with some great analysis about the worthiness of the program for buyers.

First of all, operable vehicles are required and there aren’t many people driving around with vehicles worth less than $1,500. Many old crappy cars, in fact, can still demand up to $2,500 on the open market. This means you’re going to get, max, $2000 for your trade-in. The least valuable qualifying cars, of course, are actually the more efficient compact vehicles, which makes getting the necessary 10 MPG improvement unlikely.

The second problem, stemming from the first, is quantifying the number of people who actually drive around in cars worth less than $2,500 and can actually afford a new car. Our instinct tells us there aren’t many people. This means people taking advantage of the program will, typically, have to be excited by the prospect of saving $1,000 or $2,000. These people should already have been swayed by intense discounting from automakers in recent months.
