2023's Greenest Cities in America

 My commentary in WalletHub's ranking of US green cities.

Honolulu ranked 2nd out of 100. Reno did well at 33.

Should cities invest in going green? What are the benefits?

Environmental and transportation solutions need to be tailored to an area's specific characteristics. Solutions for Tokyo are likely less suitable for Chicago. Cities with acute pollution issues should focus on smart city mitigations targeting pollution, such as electrification of bus fleets and incentives for EVs. Cities with acute traffic congestion should focus on smart city congestion mitigation, such as adaptive traffic signal management and intelligent time-dependent road pricing.

What policies or investments offer the biggest bang for the buck?

Smart traffic management for both arterial streets and freeways is the most common low-hanging fruit with moderate costs and substantial congestion and pollution reduction. Priority lanes and traffic signal preemption for Bus Rapid Transit are cost-effective smart city improvements for public transport.

How can state and local authorities attract renewable energy companies and other green businesses?

By incentivizing the electrification of transportation, substantial new demand is generated which creates a need for power supply, which in turn, makes the establishment of new renewable energy suppliers welcome. A conducive framework for power purchasing agreements needs to be in place.

What are some easy ways individuals can go green without much cost or effort?

Several smart home solutions are affordable and effective in reducing power and fuel consumption. Hybrid light-duty vehicles are presently the most cost-effective choice for commuting and highway travel. Unfortunately, recycling is more of a feel-good initiative than an effective green option given that less than 10% of what is put into recycling collections is actually recycled, reused, or repurposed.

In evaluating the greenest cities, what are the top five indicators?

A generic list may serve as a guideline, but each city needs to focus on its most acute issues and deploy smart solutions that its taxpayers can afford, for mitigations.

How Clean Is Your Electric Vehicle?

The correct answer is... it depends on the way that power is produced. For example, EVs are not very clean in Honolulu (top graph); hybrids do better. But Reno (bottom graph) has natural gas, geothermal and solar power production, so EVs there run much cleaner. Find out about EV pollution for your area by entering your zip code at the website of the Union of Concerned Scientists.

Dramatic Oil Based Sea Level Rise Is Not Possible


A major article on climate change published in the science journal NATURE concluded as follows:

"The study concludes that a moderate amount of warming, on the order of 2°C, or 3.6°F, sustained for millennia, would cause significant melting of the interior ice that lies below sea level in this region [Antarctica], raising global sea levels by 3-4 meters, or up to 13 feet."

However, there will be no oil and fossil fuels left to burn a few hundred years from now. See graph of oil reserves from The Economist, below. In addition, technology moves fast towards cleaner options, and heavy polluters like China and India cannot afford to burn coal uncontrollably because their large cities are already suffocating; more on this at The Future of Oil

Therefore, oil based global warming over millennia is not possible!

Hybrid Cars Do Well in Assessments of the Environmental Impact of Urban Vehicles

This is my contributing brief as the newest member of the invitation-only Scholars Strategy Network.

Transportation uses vast amounts of energy and has a major environmental impact. As a result, rigorous assessments of the sustainability of various modes of moving people and goods are critically important.

Alternative fuels and electric vehicles are two major developments that can help transportation planners reduce the detrimental environmental impact of transportation. After many studies, it turns out that the highest environmental-friendly scores go to hybrid diesel-electric buses, while the lowest scores go to vehicles reliant on gasoline internal combustion engines. Among all passenger vehicles, fuel cell and hybrid gasoline-electric vehicles have the highest sustainability indexes.

‘Complete Streets’ Is Just an Excuse for Government to Spend

My invited commentary in Honolulu Star Advertiser


For decades, traffic engineering meant moving cars. Planners decided that this is wrong and moved the discussion from moving cars to moving people; they said streets are not just for cars, trucks and buses, but also for pedestrians, bicycles, street cars, etc.

However, in the typical medium-to-large American city (i.e., with a metro area population of 1 million to 5 million people,) over 90 percent of the people move in cars and buses, and nearly 100 percent of the goods, move in trucks and cars. Also, in traditional and current traffic engineering practice, the service and safety of pedestrians is top priority.

So what are “Complete Streets” about? They are an excuse for government spending with undesirable economic, environmental and safety consequences, typically presented in the form of neighborhood beautification plans adorned with pleasant descriptions.

Critical Challenges in Transportation

I received a survey distributed to transportation committees of the National Academy of Engineering on future challenges that will affect transportation. My main responses are as follows.
====================

Please indicate to what extent you are interested in being engaged in activities related to the following critical challenges (not at all interested, not so interested, somewhat interested, very interested and extremely interested).

I was very interested or extremely interested in five out of the 14 critical challenges presented, as shown below along with my rationale.

Changing Characteristics of New Technologies & Innovation Environment (autonomous, shared, data-intensive): Potentially disruptive to traffic and freeway operations because we could get rid of most of roadside/ government data collection and tolling equipment, and rely on the big data generated by Connected Autonomous Vehicles (CAV).

Rapid Entry of Silicon Valley Entrepreneurs in Transportation Technology and Services: We’ve got to watch this one. If the "ITs" succeed in taking over a big chunk of transportation, their next goal will be controlling a big chunk of the government.

Changing Demographics, Values, Preferences, & Behaviors (age distribution disparities, evolving service expectations): Demographics are the most predictable among the future unknowns. But "safety behavior" will become a major challenge as driving progressively becomes a secondary task.

Climate Change (increased disruptive events, concern for sustainability): Major concern for sustainability but due to consumption and resource depletion, less due to climate effects… at least till 2050.

Challenges to Planning and Forecasting (forecasting under rapid change, addressing uncertainties, implementing new methods): 20+ year forecasts are exercises in political appropriation of funds and social engineering. Long term forecasts for facilities and services subject to a lot of possible automation aren't useful.

Hawaii's Coastal Highways

Sea level rise and extreme weather events can wash out portions of coastal highways.  This has happened several times on Oahu and many other locations.  With increasing population and traffic volume, the temporary loss of lanes or entire roadway cross sections becomes a major threat to public health and safety, let alone a threat to daily life and long term economy. Coastal roadway segments must be made more resilient to weather effects and reliable for operations regardless of storm surges.

As I outlined in a report that was the top story on Hawaii News Now (on Feb. 17, 2016--also see note 1) "Long-term solution for erosion along Kamehameha Highway won't come cheap", in general terms, the solution may come in three options, each one more suitable to various coastal highway segments (i.e., not one size fits all.)

1. Maintain the location of the current highway and elevated it by, say, 10 ft. This is a land protection option similar to those in low lying countries such as The Netherlands.
2. Relocate the highway several hundred feet inland and at a higher elevation.
3. Keep the highway largely as is and add jetties, lagoons and breakwaters to widen the coastline and isolate the highway from the forces of the ocean.

The first option requires no transportation work, but it has tremendous impacts by separating the community from the coast and a host of drainage issues. However, this "walling" option may be necessary for the effective protection of property and lives along specific sections, and at locations were current and other ocean forces make the deployment of option 3 impractical.

The second option attempts to develop a new highway in mostly agricultural, Hawaiian homestead or pristine nature areas, all of which are likely to generate insurmountable community and environmental impacts. However, there may be short segments where this option is economical and the impacts are small or moderate. For example a re-alignment of Kam. Hwy. away from Turtle Bay has been outlined in Hawaii DOT plans. Also for this option, the highway may be elevated which minimizes the disruption to lands underneath but it increases costs and reduces accessibility. Low height elevated segments may be necessary for wetland protection.

The third option, jetties and artificial ponds, is the most attractive because it protects the highway and communities, substantially reduces beach erosion and at some places adds beach or ocean recreation space. Its downside is some destruction of marine environment but some of this may be offset by the creation of traditional Hawaiian fishponds. This option also has the potential to be combined with wave action or high/low tide power generation by devices at key locations of the ponds (i.e., tidal power plants). An approximation of the proposed ponds is the lagoons at Ko'olina pictured below.


Notes
1: Two weeks later, on February 29, 2016, another segment of the same road failed due to waves, as covered in: Contraflow to last another week as crews shore up second stretch of crumbling highway.

Honolulu's Recycling Plan Needs Important Revisions

Throughout my campaigns for mayor of Honolulu I focused on the flawed recycling efforts of Honolulu. Huge amounts of effort and fuel are wasted to recycle things instead of safely burning them and making free electricity for Honolulu.

Back in 2013 I developed a pictorial guide for Honolulu.

Later in 2013, a graduate student of mine and I published an article in the Pacific Business News which revealed that "Waste to energy is superior to any other technology in the long term."

Then in July 2015 HONOLULU magazine quotes me about a dozen times in their detailed article Should Honolulu’s Recycling Program Go Up in Flames?


“Trash is treasure,” says Panos Prevedouros, chair of the Department of Civil and Environmental Engineering at UH Mānoa and a former mayoral candidate. “Not only do you make energy, you remove something that is bad.” Prevedouros adds that a waste-to-energy plant can make “serious money” charging tipping fees, selling its electricity to the utility and harvesting the valuable metals for what he calls “a win-win-win” situation: The plant helps the state meet its renewable energy goals...

Paper and cardboard are heavy and hard to compact further for efficient shipping to recycling plants; they burn beautifully, and are depressed in price. “Paper, oh, my God, it’s really perverse to recycle. We’re losing the opportunity to make energy, and we’re wasting more fossil fuel to ship it somewhere else. If you have paper, put it in the gray bin,” says Prevedouros.

Hawaii rids itself from Ethanol Mandate

Hawaii is poised to repeal ethanol in gasoline. Better late than never. This was another loser that I advised against back in 2007...

18th Century Infrastructure

In her article in the LA Times "Some Perspective on What We Have to be Thankful for" Marian L. Tupy presents a startling summary of 18th Century infrastructure that sounds so remote from first world today yet it was only 300 years ago...

"The palace also was ill equipped to deal with human waste. People relieved themselves wherever they could. Thus, shortly before Louis XIV died [in 1715], an ordinance decreed that feces be removed from the corridors of Versailles once a week. All that filth meant that disease-spreading parasites were rife. Before the 19th century, people had no idea about the germ theory of disease, and doctors often caused more harm than good."

"If this was the life of Europe's richest and most powerful man, imagine what ordinary people's lives must have been like. People lacked basic medicines and died relatively young. They had no painkillers, and people with ailments spent much of their lives in agonizing pain. Entire families lived in bug-infested dwellings that offered neither comfort nor privacy."

And here is a depiction of 18th century London's life and hazards.

Letter to the Honolulu City Council: Hoopili Doesn’t Fit

Mahalo to Honolulu Civil Beat for publishing my Letter to the Honolulu City Council: Hoopili Doesn’t Fit.

This version includes the pictures in Appendices A and B.

I concluded by saying that it baffles me beyond belief that the Honolulu City Council is serially approving future development such as Ho'opili and transportation projects like the rail that are certifiably calamitous for our island community.

As the Nation Turns, Hawaii is Still Driven

As the Nation Turns, Hawaii is Still Driven is an comprehensive and detailed article in the November 2014 issue of Hawaii Business Magazine, by Carlyn Tani. I am quoted extensively throughout the article as follows:
  • “Hawaii’s driving never really went down – it just flattened out and then started going up again as opposed to the mainland, which made a U-turn,” observes Panos Prevedouros, who teaches civil engineering at UH-Manoa and chairs the freeway operations simulation subcommittee of the Transportation Research Board, a division of the National Research Council. He projects that Hawaii’s thriving economy and tourism sector will buoy VMT even higher.
  • Prevedouros cites three economic forces driving Hawaii’s trend toward more vehicle miles driven per capita: a rebound in tourism, which puts more visitors on the roads; the construction boom on Oahu, which stimulates the transport of people and materials; and the large number of Hawaii residents who hold more than one part-time job and drive between workplaces.
  • According to Prevedouros, the general tolerance threshold for congestion is 75 minutes for a one-way trip by car. When commute time exceeds that, people are more likely to move, change jobs or relocate to another region or state.
  • But what does Hawaii’s transportation future look like? Prevedouros predicts that cars will continue to dominate because of the state’s tourism-dependent economy, high private-schools enrollment and large number of people holding more than one job.
    “We don’t have mass transit that is flexible and quick enough to take you to drop off your kids or take you to your multiple jobs. You cannot be a resident in Kailua with kids at Punahou and try to do these things by bus,” he explains. “The only mode that can deliver that is private transportation.”

    Prevedouros predicts we will see more cars on the road in the future, but says traffic congestion will eventually be reduced by autonomous cars that drive better than people-driven cars, while more energy-efficient cars will ease environmental concerns.

Climate Change and Hurricanes in Hawaii

While many journalists and some scientists attribute more, and more severe storms to climate change, trajectory plots of major storms and hurricanes in Hawaii over the past of 65 years shows an "inconvenient truth": There is no association with climate change. Hurricane frequency in Hawaii appears to have peaked in the 1980s.

Ten Plus One Reasons Why I Do Not Support The Honolulu Rail Project

  1. Among all travel options on Oahu, mass transit serves 6% of the travelers, just slightly above the U.S average of 5%. Focusing on this small piece of the pie is no way to solve the mobility problem of the 80% that drive and carpool, i.e., rail is the 1% solution because City's rosy numbers show that transit share will grow from 6% now to 7% with rail.
  2. Spending over five billion dollars for a non-solution is clearly unethical and all responsible for it are breaching their professional and fiduciary duty. As an engineering professional and past candidate for mayor I want no part in this unethical endeavor.
  3. The original system was supposed to be 34 miles through Kapolei to UH and Waikiki for about $3 Billion as shown in the headline above.  The current project starts a mile out of Kapolei and dead-ends at Ala Moana shopping center with no service to Waikiki or UH. Just 20 miles for over $5 Billion. If offering the public 41% less for a 73% higher price is not a lie then what is it?
  4. In some respects Oahu's congestion is comparable to that of the largest cities in the nation chiefly because Oahu is lane deficient.  20 miles of rail and 20 overhead stations will cause critical lane closures and result in debilitating congestion for a decade or more. For example, look at the image below and consider what traffic in downtown Honolulu will be like with Ala Moana Boulevard closed for about a year? The impact on quality of life, economy and tourism will be huge.
  5. B, C, E, 3, 9, 11, 20, 43, 53, 73, 81, 90, 91, 92, 93, 94, 96, 97, 98A, 101, 102, 103, 201, 202 are all the bus routes that will be eliminated or terminated to the nearest rail station. TheBus will be changed from a core operation to a feeder operation. This will add a lot of inconvenience and disappointment to the people that need transit service the most.
  6. Rail is high security risk. Mentally ill shooters and terrorists typically attack work, school and train station locations. Third rail systems like Honolulu's are a magnet for suicides. Train stations are a hot spot for robberies and drug trafficking.
  7. Rail makes Honolulu less resilient:It is practically certain that a major storm will hit Oahu in the next 50 years. Ten miles of reversible lanes not only will reduce congestion by over 30% for one third the cost of rail, but also they will be a critical backbone for post-storm recovery. Instead rail will be incapacitated for a prolonged period and critical resources will wasted to revive it.
  8. Cannot afford it. Hawaii is among the five worse states in the country in pension and health benefit funding liability. Future budgets will be very tight for the state. Outer islands should worry about their loss of big subsidies they receive from Oahu (i.e., they too will pay for it.)
  9. The City already has big problems finding a few million dollars for important services. Its budgets will be crushed by the union raises, the EPA sewer consent decree and the pension liabilities. Then add the rail construction cost-overruns and bankruptcy may not be far off.
  10. Out of more than 650,000 adults on Oahu only 156,000 voted YES to rail in the 2008 elections. That yielded a marginal 50.6% approval among those who bothered to vote. During elections the ratio of pro-rail lies to anti-rail information in advertising media was more than 10 to 1. Taxpayer monies were used to support rail and, indirectly, rail-supporting politicians. Calling this a "mandate" is disingenuous and the process was indeed unethical.
Last but not least, the aesthetics of the system are undesirable for the small, tropical capital of Honolulu. Here is just one before/after picture offered in city's renderings.

Plan Bay Area: Urban Planning as a Form of 21st Century Illogical Dictatorship. Part 2

Part 2 is lawsuit galore. Barely two weeks after its acceptance by Bay area planning and transit agencies, Plan Bay Area was Sued From the Right and the Left!  Of course the myopic view of Sierra Club forces them to sue the Plan for daring support some highway transportation.  As I have demonstrated in my critique of the Plan, its emphasis on transit is totally wrong. Sierra Club wants more emphasis on top of emphasis on transit. It is quite clear to me that the title Lunatic Left is becoming a fundamental characterization.

Plan Bay Area: Urban Planning as a Form of 21st Century Illogical Dictatorship. Part 1

Part 1 by Wendell Cox explains why the well intentioned Plan Bay Area makes the wrong assumptions and picks the wrong solutions. As a result it barely makes the pollution targets they are after!  Sample estimates by Cox are shown the picture below.  Telling people what to do is not the way to do it.

Electric Vehicles Are Here to Stay. In Moderate Numbers.

The MIT Review titles the infographic below: Electric Vehicles are Here to Stay.

Yes, but the case for them is not particularly strong and their market penetration will be small for a very long time, for two big reasons.  One is EV's marginal environmental benefit. The infographic clearly shows that the big improvement comes when a gasoline-powered vehicle is converted to hybrid: Its emissions drop from 0.87 pounds of CO2 per mile to 0.57 pounds per mile. All the fuss to get to EV cuts CO2 down only to 0.54 pounds per mile (and probably leaves a much bigger problem with battery recycling at the end.) In addition this estimate does not likely account for all the charging infrastructure that is being installed from scratch.

The second reason is the affordable price of fuel, gasoline in particular. It will be priced at around $4 per gallon for a long time thanks to major forces that work against major price increases, such as:
  1. Hydraulic fracturing of fracking for natural gas extraction, which curbs the demand for oil by vast amounts. (In 2000 fracking yielded 1% of the natural gas production in the US. In 2010 it yielded 20% of the production. A breakneck acceleration in such a capital intensive industry thanks to my fellow Greek and father of fracking George Phydias Mitchell.)
  2. Sustained oil prices in the $50 to $100 per barrel make expensive explorations affordable, so a healthy supply of oil will be available to satiate the increasing demands of the developing world.
  3. Substantially decreased demand for gasoline due to the popularity of high mpg vehicles (CAFE requirements and sales success of hybrids and plug-in hybrids; can't buy a Hummer anymore.)
  4. Less travel due to persistent high unemployment and mega economic downers such as debt, deficit, bankrupt cities and countries, and looming pension and health care social costs in the US.
  5. Continued public and private investment in renewable sources of energy.

Circuit of the Americas: Racing to the Finish

"When in 2010 the city of Austin, Texas, was awarded the United States Grand Prix for 10 years, plans to construct the Formula 1 racetrack there, the Circuit of the Americas, quickly got under way, and an unlikely midsize civil engineering and surveying firm was awarded the civil engineering design contract."

This is a fascinating story of infrastructure development for a top flight world sporting event. Read this open article starting on page 64 of the Civil Engineering Magazine, May 2013 issue, of the American Society of Civil Engineers: Racing to the Finish.

Sierra Club Used Wrong Population Projections in Support of Honolulu’s Rail

If one wants to keep things simple, then it could be said that the base of Sierra Club's support for rail is simply a case of garbage in, garbage out.  In other words, garbage data were used to come to a garbage conclusion.  However, I believe that data were sufficiently twisted to support the underlying car-hating philosophy of "environmentalists."

In this case, the bias is clear because supporting rail (to kill auto) causes huge damage to prime agricultural land. The Sierra Club simply cannot have it both ways.

Explanations are provided in my article in the Hawaii Reporter.
