Learning about BioDiesel

The price of fuel, whether it is heating oil, diesel, or gasoline, seems to perpetually be on the rise here in Connecticut, making it increasingly more important for consumers to be informed about the different types of fuel available.

After attending the 2013 Regional Biodiesel Industry Forum hosted at the University of Connecticut, I learned a lot about the benefits of one fuel source that few consumers are familiar with; biodiesel.

Biodiesel is actually less expensive than petroleum based-diesel, outperforms both natural gas and petrodiesel in home-heating systems, and is one of the more sustainable fuel sources.  The following are just a few more things that I didn’t know about biodiesel; they surprised me and they very well might surprise you too!

 

Inexpensive

  • With state incentives, biodiesel can be up to 50 cents cheaper per gallon than petrodiesel

Great performance

  • Vehicles running on B20, a blend of 20% biodiesel and 80% petrodiesel, have the same fuel consumption, horsepower, and torque as vehicles running on conventional petrodiesel
  • When mixed with No. 2 diesel, B20 performs the same as petrodiesel in cold weather
  • Biodiesel has a BTU value comparable to petrodiesel
  • Most vehicles manufactured after 1993 can use biodiesel blends up to B20 without any impact on operating performance
  • When biodiesel is first introduced to an engine the filters get clogged more frequently because the biodiesel actually cleans out build-up left behind from petrodiesel
  • The waste cooking oil used to manufacture biodiesel must be purified and meet very specific standards in order to be used as biofuel
  • Biodiesel actually performs better than petrodiesel in many systems due to better lubricity and other chemical properties of the biodiesel

Sustainable fuel source

  • Biodiesel releases fewer toxins, particulate matter, and greenhouse gas emissions than conventional diesel
  • Biodiesel is an advanced fuel meaning that it is produced on existing land and reduces life-cycle carbon emissions by 80% as compared to petrodiesel
  • Biodiesel is a byproduct of producing high-quality meats, fried foods, and high-protein soybean meal and as demand for biodiesel increases the cost of these food staples can decrease

By switching to biodiesel in home-heating systems as well as in vehicles you can save money without sacrificing performance, and at the same time you can help improve environmental quality.

EV Charging Station

The University of Connecticut was one of eighteen locations selected by Connecticut Light & Power (CL&P) for their “Plug My Ride” program. There is already one electric vehicle charging station on campus located in the Motor Pool parking lot. It is open to the public for free use between the hours of 8:00AM and 4:00PM.

Image

Over the past year, CL&P and the University’s School of Engineering conducted a study on the charging station and concluded that it was in the top 5% for usage among all of the charging station included in the study (more information about the Plug My Ride Case Studies can be found here: http://plugmyride.org/Case_Studies.aspx). Recently, UConn’s Department of Transportation (DOT) and student interns at the Office of Environmental Policy (OEP) collaborated to acquire a grant for the installation of two more electric vehicle charging stations. The Connecticut Department of Energy and Environmental Protection (DEEP) agreed to fund the installation of two more electric vehicle charging stations on campus. The two additional charging stations are to be installed in both of the parking garages – one in North Parking Garage and another in South Parking Garage.

Image

The existence of two more electric vehicle charging stations will further promote the use of hybrid and electric vehicles. The additional charging stations will also provide the University with the potential to purchase more electric vehicles in the future to improve the fuel efficiency of its fleet, and will prompt the possibility of adding more electric vehicles to the “Hertz on Demand” car sharing program. Not only do electric vehicles contribute to cleaner air quality and lead towards a more sustainable planet, but they are also economically advantageous and energy independent.

Carpooling at UConn

Attention UConn commuters! This year, parking services is offering a carpooling program available to commuter students at the University of Connecticut.  The aim of the program is to encourage students to reduce their carbon footprint with the incentives of saving gas and money by riding to school together.  Carpooling is also a great way to save some money on your parking pass!

Students may choose to share a permit for North or South Garage, commuter lots, W Lot, or C Lot.  The great thing about this permit is that you’re sharing the space, not just one car.  Because each carpooler’s vehicle is registered, you can rotate who’s on driving duty.  Additionally, parking services provides 2 complimentary day passes per carpooler into this deal that can be used in any commuter lot, just in case you can’t make the carpool sometimes.  If 2 days isn’t enough, additional permits may be purchased at a low price.  So if you’ve got a couple of friends who also commute to UConn from your area, then get together and purchase a carpool permit!  Check out the parking services webpage to learn more about how you can sign up for this great program.  http://web2.uconn.edu/parking/carpool.html

Sustainability Exchange – Part 2: Bicycle Transportation

A UConn “Sustainability Exchange” Experience –  Bicycle Transportation in Freiburg, Germany

Preparing for my trip, I had read that Freiburg, a large college town by any standard (pop. 220,000), and an increasingly popular tourist destination for all of Europe, the US and other parts of the world, was not only Germany’s “solar city,” which makes sense given that it enjoys more sunny days than anywhere else in Deutschland, but also its “cycle city.”  With this in mind, I had packed my bike helmet, gloves and shorts and made plans to rent a bike at The Mobile.  This is a large, multi-story facility, which was built to serve as the city’s public bike station and is connected by a pedestrian bridge to the train and bus stations.  I had read that as many as 30 percent of Freiburgers commute to work, class, and almost anywhere else they’re going, by bicycle – that number seems lower than what I observed.

“The Mobile,” a public bike station in Freiburg, rents and loans hundreds of bikes daily.

The easiest way to describe the difference between biking in Freiburg and the US, even compared to a college town like Storrs, is that bicycling here in southwest Germany, among students and the masses, is predominantly an alternative mode of transportation, certainly much more than it is a form of recreation or sport.  Bikes here are mostly very practical, low-frills models with wider hybrid tires and seats, straight handlebars, and metal basket clips and fenders.  In fact, most of them resemble the standard-issue “UConn Cycles” bike-sharing 3-speed models (the kind we selected to deter their theft).  The expensive, aerodynamic bikes so popular in the US, like the ultra-light racing bikes, are few and far between.  Upscale mountain bikes with the heavy-duty shock absorbers and hydraulic brakes are slightly more noticeable on the Black Forest’s wooded trails, which border the city and climb up to many scenic hilltops and steep “bergs.”  People of all ages ride everywhere, rain or shine, day or night, in their normal everyday attire: from business suits and ties, to long dresses, skirts and skinny jeans, and with footwear from dress shoes, sneakers, sandals and boots, to bare feet.  Helmets and spandex bike shorts, so popular among the “weekend warriors” in the US (myself included) are scarce in Freiburg.

The Mobile is connected by the pedestrian/bike-only bridge (left) to the main bus and train stations.

Biking here on the Freiburg Uni campus and in the city is all about getting where you need to go… quickly.  My $4 Freiburg metropolitan area bike map, with the solid red lines indicating separate, paved bike trails, and dotted lines for pavement-marked lanes alongside the walkways or on the shoulders of streets, showed a network of trails so numerous and inter-connected that it looked like a half-eaten plate of spaghetti.  It’s all so convenient and connected that the university has found 5,000 bike racks on campus are not enough! According to Dr. Juergen Steck, my host and counterpart at the university, this has become a problem for senior administrators, because hundreds of bikes are routinely locked to lamp posts, fences, trees and anything else fixed to the ground, becoming an eyesore and occasionally even a fire safety issue when blocking exits and access points. Help is on the way! The university will be adding 500 bike parking spaces in the basement of its new library, now under construction and expected to open next year.

5,000 bike storage racks on the Freiburg Uni campus, such as the covered racks to the left in this photo, are still not enough! Bikes are chained to everything, like the railings and lamp posts in front of this classroom building, posing aesthetic and safety concerns.

A note about bike safety is relevant here.  Many times last year, when our UConn Cycles team prepared to launch the campus bike-sharing pilot program, I heard from several faculty and staff members about how they had almost been run over by a careless cyclist.  They chided me that maybe encouraging more bikes on campus wasn’t such a good idea after all. So, we created a bike safety flyer, tightened our liability waiver form, took a deep breath and forged ahead.  Fast forward to southwest Germany in this summer of 2012 and picture dozens, if not hundreds, of bikes fearlessly zipping along the streets and narrow cobblestone roads and walkways, often weaving through pedestrian and vehicle traffic that is every bit as heavy as it gets on North Eagleville Road (in the Science Quad) between classes, and you’ll have a pretty good image of Freiburg. Cars, bikes and pedestrians here have learned to peacefully coexist. Everyone defers to cyclists, who seem pretty attentive and experienced at avoiding collisions. However, when I remarked to Freiburg’s director of education and the environment, Dr. Franziska Breyer, that I had seen very few riders, except for pre-teens, wearing bike helmets, she seemed resigned to the fact that an adult helmet law would not be enforceable.  And yes, she acknowledged, they have had their share of bike-related accidents. Those must have been involving the few adults I saw now wearing helmets.

Bike taxis (and even a few passenger-pedaled buses) were popular in Freiburg’s beautifully restored and preserved Aldstadt (”Old City”), where motor vehicles were mostly prohibited.

Renting a bike was less expensive than in the US (finally something less expensive!) and cost about 8 euros ($10) for a half day or 15 euros for an entire day. The 50 euro refundable deposit made me thankful that I brought extra cash in my pack.  Busy staffers at The Mobile quickly fetched a well-maintained 7-speed “city bike” from the well-stocked racks of similar bikes for rent. They demonstrated the rear wheel locking mechanism, with the key that could only be removed when the bike was stopped and locked (I made a mental note for UConn Cycles), then directed me to the Dreisam River trail and sent me on my way – no liability waiver form was presented for my signature and no helmet was offered.

The trail along the cascading river, stretching for miles in either direction beyond the city center, was simply one of the most scenic, smooth, uninterrupted and enjoyable bike paths I have ever ridden. The scenery transitioned seamlessly (see photos below) from busy city blocks, to suburban village-like districts, to sports fields and playgrounds, then under or over the autobahn and out to the bucolic farms with herds of goats and sheep, past acres of corn and wheat fields. There were plenty of intersecting bike trails along the way that I would have loved to explore.  We headed west when we meant to go east to find the solar soccer stadium on the outskirts of the city, so had to double back and ended up riding for more than 20 miles, stopping occasionally to take pictures.

Once back within the city limits, we found lunch at a Turkish restaurant not far off the Dreisam River trail.  While this ride was all very pleasant for me, I still didn’t get the impression that many of the locals were riding for pleasure.  The vast majority appeared to be biking solely for transportation.

Freiburg proved to me that when biking becomes a lifestyle choice and serves as a mode of transit that literally replaces the use of cars and other motorized vehicles, the population becomes healthier.  I’m no slouch on a bike but many of the locals, young and old, passed us as we pedaled along at our leisurely pace.  I’ll admit that I found it a little bit frustrating that I couldn’t easily close the distance between myself and an elderly white-haired gentleman in jeans and a t-shirt, or a middle-aged woman in a long skirt, whom I guessed could have been heading to her apartment for a lunch break – not exactly like trying to make up ground on the peloton at the Tour de France. Between biking everywhere, and hiking and mountain climbing in the Black Forest, Freiburgers are in good shape! Or maybe it’s the local beer….

Sustainability Exchange – Part 1: Public Transportation

A UConn “Sustainability Exchange” Experience – Public Transportation to, from, and in Freiburg, Germany

This is series of blog posts by Rich Miller, UConn’s Director of Environmental Policy, comparing and contrasting aspects of environmental sustainability at Freiburg University (Albert Ludwig University at Freiburg or Freiburg Uni) and in the “Green City” of Freiburg, Germany, with similar sustainability aspects and metrics at the University of Connecticut (UConn) and its main campus located in Storrs, within the small town of Mansfield, and the rural surroundings of northeastern CT.  Rich received a professional staff travel grant from UConn’s Office of Global Programs and used it to visit Freiburg over a two-week period in July 2012 for this international sustainability exchange program.

How do the Germans and foreign visitors travel in and around Freiburg?  Are alternative modes of transportation popular and encouraged by local government, institutions and businesses? Is public transportation convenient, accessible and affordable to the masses?

At first, mass transit in Germany didn’t seem much different from airports and buses in the U.S., at least not based on my departure from JFK airport in NY and my arrival in Frankfurt, Germany.  After the short flight to JFK from Hartford, we settled in for a two-hour layover. But as boarding time neared, we were shuttled from the crowded and rather run down international terminal to the new and more spacious one still under construction.  Hate to think what would have happened had we not heard the announcement about that gate change and then missed the 15-minute shuttle bus ride across a corner of the busy runway, just in time for boarding.  After an overnight, wind-aided 8-hour flight to Germany, I was a little stiff and sleep-deprived, but well caught up on a few recent movies.

Once safely on the ground and through customs and baggage claim in Frankfurt, we waited briefly in line for the free shuttle to the train station.  On the bus, we were instructed in three languages, German, French and English (thankfully, this is a standard practice for internationally-frequented mass transit systems in Germany), that it would be an 8-minute ride.  Accurately timed, I’d say! I compared this precision with the shuttle across the tarmac at JFK, where we waited for clearance at several points along the runway and the driver risked no attempt at such an announcement. At Frankfurt’s main mega-train station, which, in the US resembles NYC’s Grand Central Station or a mid-sized airport terminal, we needed to find our way to the high speed/direct train line, aka ICE (Inter-City Express), to Freiburg.  Through the ICE, the German Railway offers clean, fast and sleek trains with direct connections to several larger cities in Germany and beyond.  While this is similar to the newer high speed/bullet trains between Washington, DC and NYC, the ICE covers a much larger area and serves as a convenient, mass transit backbone for most of Germany.

The ICE to Freiburg would be a 2-hour ride, costing about $65 a ticket – not cheap, but compared to the price of gasoline in Germany, a relatively affordable option.  I saw a gas station sign for regular at 1.57 euros per liter, which translates to about 6 euros/$7.22 a gallon.  Of course, the price for everything is higher for us Americans, given the poor euro-to-dollar exchange rate.  We hurried to exchange currency and purchase our ICE tickets, knowing that the Freiburg train left at two-hour intervals and not wanting to prolong the trip with a layover if we could avoid it. We made it to the ICE gate with 5 minutes to spare! But as it turned out, the train arrived a few minutes late – something the conductor would later apologize for in his announcements at several stops – in three languages, no less.  I wish the overnight flight from the US had been as spacious and comfortable as the ICE train – I might have gotten some sleep.

Front entrance to the main train station (Hauptbahnhof) at Freiburg.

Freiburg taxis – most of them VWs of course, and all of them fuel-efficient sub-compact cars, were waiting curb-side at Freiburg’s impressive main train station, located adjacent to the bus station and the public bike rental center.  This complex served as a combination “mobility station,” shopping mall and city gathering place of sorts – cafes, fast food, grocery and sporting goods stores, bakeries, travel agencies and information stations, crowded with residents, commuters and tourists alike.

Outside the train station, I caught my first glimpse of the electric trams, which continuously loop on tracks and cables throughout the city, including stops within the historic Altstadt (Old City), where motor vehicles are mostly prohibited, and at scattered sections of the Freiburg Uni campus. When I took the tram to the city’s Vauban eco-district (one of the many destinations on my Green City map) I found it to be faster than traveling by car or bus, but probably not as efficient as a bicycle, had I known my way around town.  Buses in Freiburg generally don’t compete with the trams in the Altstadt or inner-city but instead travel to the outskirts of town and beyond.  In addition to transit and commuter buses, there were steady streams of buses arriving and departing daily with groups of tourists and shoppers.

Two of the continuously-looping electric trams wait for passengers to board in Freiburg’s Altstadt. For a few euros or less, the trams will take you anywhere you need to go in Freiburg, from the inner-city to nearby village districts.

While there’s no real comparison between mass transit at UConn, in rural Mansfield, with the impressive public transportation network that Freiburg Uni enjoys within a city the size of Freiburg, it’s also fair to point out that UConn has had to piece together its own system for transport on- and off-campus.  UConn’s continuously looping shuttle buses are always free to students, faculty, staff and the public. This fall (2012), new streamlined bus routes, designed to reduce wait times as well as total mileage, will be unveiled. During the school year, through arrangements with companies like Mega-Bus, Huskies can find low-cost fares for direct trips to NYC and Boston available daily. If more flexible or convenient transportation to other off-campus destinations is needed, students and others can now rent one of four ultra-low emissions vehicles stationed around campus, available at low-cost hourly rates (gas and insurance included) through UConn’s new car-sharing program, run by Hertz-On-Demand.

Back at the Freiburg Hauptbahnhof, after coffee on the ICE train, the restroom beckoned.  The one and only “WC” (water closet) or public restroom at the main train station required 0.80 euros (roughly $1) per person, payable at the turnstile entrance.  This can be said from my experience – very little in Germany is free of charge – clean, accessible and efficient, yes, but everything at a price.  Even this blog comes across the internet at a special discount rate of 5 euros per day (versus 3 euros per hour) from the w-fi equipped hotel.
