The full paper is titled: LIFE CYCLE ASSESSMENT THROUGH A COMPREHENSIVE SUSTAINABILITY FRAMEWORK: A CASE STUDY OF URBAN TRANSPORTATION VEHICLES
Civil Engineering Professor Panos D. Prevedouros, PhD discusses his opinions on infrastructure issues with emphasis on the City and County of Honolulu.
Energy and Honolulu rail is an angle that I did not have time to look at in detail, until last week when my students did some energy analysis of Honolulu’s proposed rail. They discovered this June 2008 article by Sean Hao: Rail's use of energy subject of debate in the Honolulu Advertiser.
Of note is that the rail will consume about 20 MW of energy which is about 20% of the capacity of HECO’s new palm oil plant. Unfortunately peak rail travel coincides with peak demand for electricity around 6 PM, which means that rail will stress HECO’s generators.
Now if you believe the city’s numbers which are based on incredible ridership projections and substantial bus route eliminations, Table 4-21 of the Final EIS shows that the rail project will save 2,440 million British thermal units (BTU) of energy each day, or about 610,000 million BTU per year.
Hao correctly added that: “Any evaluation of the energy savings generated by rail also needs to consider the massive amount of energy required during construction. For example, construction of the fixed guideway will require between 3.7 trillion and 4.9 trillion BTU of energy, according to Parsons Brinckerhoff.”
This quote reveals two startling facts:
First the unnamed Parsons Brinkerhoff source clearly lied to Hao by stating roughly half the correct amount of BTU. The 2008 Draft EIS, Table 4-34 on page 4-159, shows that the rail’s Airport alignment will require 7,480,000 MBTU. That’s 7.5 trillion BTU, not 3.7 trillion.
Second, by dividing 7,480,000 by 610,000 we get 12.2. That’s how many years it will take to make up the construction energy loss by the purported energy savings. But in reality these 12 years are an understatement because Hawaii's vehicle fleet is much smaller in engine size (more economical) than mainland fleet and the adoption of hybrid and electric vehicles is vastly bigger on Oahu. In addition the national averages are based on low vehicle occupancy, whereas Oahu has among the highest transit and carpooling rates, so BTU per passenger mile is way lower than mainland.
The City's BTU savings estimate may be wrong by a factor of 3 or larger, so it will take so many years for rail to "make up" its construction energy waste that before break-even is reached, rail will need multiple component replacements, repairs and refurbishments. So an energy black hole it is!
On the other hand, our 2008 simulation estimates using the DEIS traffic numbers show that rail is a net energy loser without even counting the huge energy consumption during construction. In comparison, a properly designed and operated HOT lane system will save energy (motor fuel and oil.)
Fuel Consumption for One Peak Hour (in US gallons) | ||
ALTERNATIVE | Motor Fuel | Motor Fuel plus Diesel at HECO for Rail |
Rail: 6.5% traffic reduction | -2.6% | -0.3% |
Rail: 3.25% traffic reduction | -0.4% | 1.9% |
HOT Lanes and Four | -40.5% | -40.5% |
Jade used her MidWeek column, plenty of emotion and wrong information to paint a favorable picture for Honolulu’s proposed elevated rail which she wants and supports. (Read it here.)
Jade issued a call to action because the pro-railers are not being heard. “I think it’s time for rail supporters to come back out and make a little noise. Make yourselves heard again.”
At the same time, the City shamelessly uses tax monies to produce, print and mail hundreds of thousands of gloss fliers to households monthly, it produces TV programs including a regular spot on O’lelo, it gives rail propaganda shows with food and music at high schools and colleges, and Inouye, mayor or HART have at least one press release or pro-rail event every week.
Moreover, the Star-Advertiser routinely rejects anti-rail letters and MidWeek has refused my multiple offers to print my articles. Councilman Tom Berg is being shadowed by Go-Rail-Go every time he arranges a townhall meeting with rail on the agenda. Pro-rail unions flooded the Land Use Commission hearings on Ho’opili recently. But none of this is enough for Jade. She wants to make sure that anti-rail voices are swamped.
“Our future demands that we protect our environment, that we have viable transportation choices. Clean mass transit must be one of the options on the menu” she claims.
The energy required just to build the foundations, columns, structures and trains involved is enough to give an energy consumption and pollution stroke to anyone willing to quantify it. National statistics clearly show that hybrid cars are less energy demanding and polluting than heavy rail, and 4-cylinder cars are not far behind the hybrids. That’s by mainland standards which include substantial nuclear and hydro (clean) power and less than 3% oil. In contrast, over 90% of Oahu’s electricity comes from oil with little end in sight. It is the dirtiest electricity in the U.S.
Remember that a parked car does not pollute. A train runs less than half full most the time. Plus station lights, elevators, escalators, ticket machines, controllers, air-conditioners are on all the time. What a waste of resources!
Here is a green transportation alternative for Jade: Telecommuting. Since the turn of the millennium, more Americans telecommute than take trains. Also two years before the 2008 “rail referendum” on Oahu there was another one about bikeways and a whopping 72% were in favor. What did Mufi I (Hannemann) and Mufi II (Carlisle) do about bikeways? Where is Jade’s outrage for this green mode? Perhaps bikes are ignored because they aren’t HECO customers.
“It would revitalize the construction industry…” No, it’ll keep some of them busy for a few years. Then what? Megaprojects are not sustainable. All they do is create “bubbles” of temporary growth. This point is too myopic to discuss any further.
“…stimulate business and economic development and provide opportunities for employment.” Maybe, but correctly spent, six billion dollars can go way further for Oahu. Here is a suggestion: A $6 Billion Plan for Hawaii's Long-term Prosperity.
“Listen to the voices of the people who are tired of traffic hell.” I’d agree that by local standards the Kapolei to town commute is what Jade calls “traffic hell.” But Oahu’s congestion ranking is between 49 and 52 worse in the US according to the Texas Transportation Institute congestion index estimations: Mobility Data for Honolulu (2004 to 2009.)
“My biggest fear for rail is that it will somehow stumble into a legal no man’s land.” Jade got this right. Even if the Cayetano, et al. suit fails, even if the Bombardier complaints fail, there will be dozens of eminent domain and other suits. Big projects typically get stuck. One heiau in Halawa did it for H-3 Freeway. How’s several football field sized stations in Waipahu, Kalihi, Kakaako 40 ft. up in the air?
Rail for Oahu has been, is and will be a losing proposition. Manini traffic relief, huge visual and environmental impact, colossal cost to implement, and ridiculous traffic and court tie-ups once real construction begins.
I am optimistic about the outcome of the lawsuit against Honolulu Rail in federal court. There was no such suit against the Silver Line addition to the Washington DC Metro. So the line is now under construction. These two excerpts from a recent article in New Geography are important:
What's important is that this system is about the same length as Honolulu's, and it is heavy rail like Honolulu's. So despite the fact that its construction is relatively easy (in the middle of an existing toll road) compared to the nightmare of shoehorning elevated stations and guideways in densely populated Honolulu the cost is staggering and it will likely surpass $7 Billion.
Remember that the financial analysis report conducted for Governor Lingle said that the likely cost of Honolulu Rail will be $7.2 Billion.
So when mayor candidate Carlisle promised that he will "get Honolulu's financial house in order" what did he mean? The answer is clear: "Adding several Billions of new debt onto Honolulu's financial house."
I strongly suggest that you read the rest of the article linked above as it presents a most suitable solution for the Dulles connection and for Honolulu: Bus Rapid Transit on HOT lanes. Much better results are a much lower cost.
