For Every Green Job, Four Other are Lost

A few posts below you can read my opinion about Wind Energy for Hawaii
http://fixoahu.blogspot.com/2011/04/wind-energy-for-hawaii-great-for.html

Today I was sent this revealing study done at the UK:

Part of the summary in offshoreWIND.biz reads as follows: A study of renewable energy in Scotland shows that for every job created in the alternative energy sector, almost four jobs are lost in the rest of the economy.

Not only has the sun set on the British Empire, but the promise of wind apparently is deserting it as well. A new study called “Worth The Candle?” by the consulting firm Verso Economics confirms the experience of Spain and other countries: The creation of “green” jobs destroys other jobs through the diversion of resources and the denial of abundant sources of fossil fuel energy.

Here is the full report: “Worth The Candle?”

Board of Water Supply: For Crying Out Loud!

In 2009 and 2010 the Board of Water Supply tore up the upper half of Pacific Heights Road to upgrade the water lines and meters. The bumpy condition of the road (in part) cost me $800 in replacing the front suspension bushings of my car at 45,000 miles (normal wear should be 100,000 miles or more.) At the end of 2010 MIRA contractor spent over a month paving the road. They did a decent job.

Four months later the same road is marked to be torn up to fix the sewer lines, by the same Board of Water Supply. It really does not get more costly and disruptive than this…. Heavy machinery… Line up in single stack… Off duty police officers at both ends… Etc.

As can be seen in the photos below, the asphalt is dark black; brand new with a likely service span of 15 to 20 years. Actively being destroyed today.

Huge Combustion Efficiencies Are in the Works

The York Times article Start-Ups Work to Reinvent the Combustion Engine reports that
  • Pinnacle Engines is working on an engine that "will be up to 50% more efficient than today's power plants,"
  • EcoMotors, "a Detroit area start-up backed by Khosla Ventures(1) and Bill Gates," and
  • Achates Power of San Diego
are developing variations on an opposed piston engine...long considered too expensive and unworkable for automobiles. The goal is to reduce the amount of energy "wasted as heat," so as to "to tap more energy to propel a vehicle." Pinnacle says that its current engine is "30% more efficient than current scooter engines." EcoMotors "is also claiming up to a 50% improvement in efficiency for its two-stroke diesel opposed piston engine." Achates Power says that its engine is "15% more efficient than conventional diesel."

In addition I recently read that both the Engine Research Group of University of Wisconsin-Madison is working on dual fuel engines to achieve high efficiencies and low emissions. An example of dual fuel is engine uses 90% gasoline on high load (acceleration), 90% diesel on low load (cruise) and 100% diesel at idle. Fuel efficiency improved 20% to 25% or large engines for trucks and heavy equipment.

At the same time and the Oak Ridge National Lab is conducting similar experiments using 1.9 liter Euro spec GM diesel engines with good results.

These are all positive and telling signs that the "classic" engine and the automobile are nowhere near their "dawn" days.

(1) Vinod Koshla, of Khosla Ventures, a Silicon Valley venture-capital firm. His profile in The Economist is worth reading. I liked this quote of his: “ENVIRONMENTALISTS are fiddling while Rome burns. They get in the way with silly stuff like asking people to walk more, drive less. That is an increment of 1-2% change. We need 1,000% change if billions of people in China and India are to enjoy a Western, energy-rich lifestyle.” Forget today’s green technologies like electric cars, wind turbines, solar cells and smart grids. None meets what Mr Khosla calls the “Chindia price.”

Wind Energy for Hawaii: Great for Profits, Not So Great for Power

Electric power is all about baseload and predictable peaks of usage. Wind is all about unpredictability. Among all major resources for the production of energy, wind is among the least predictable and dependable. Full article published in Hawaii Reporter.

"Smart Technologies" Could Improve Transportation

The post below is excerpted from the American Society for Engineering Education (ASEE) daily newsletter. It summarizes an attempt of Congress to improve transportation conditions by employing Intelligent Transportation Systems (ITS).

I have been teaching these methods for over a dozen years as part of my CEE 661: Intelligent Transportation Systems graduate course at the UH-Manoa. What is different this time is $1.2 Billion dollars in federal funding over six years for the pilot deployment in six competing cities.

I hope that the bill will go forward and I hope (but do not expect) that Honolulu and State of Hawaii will vie for this ITS initiative. Besides being substantially congested, Honolulu presents an excellent, fully controlled traffic laboratory. By that I mean that 100% of the traffic is local, as opposed to, say, Chicago, that at any time 5% to 15% of its traffic is from neighboring Indiana, Wisconsin and other states, thus its local ITS initiative is diluted by a large number of non-participating vehicles.
===========================================

The Hill (3/30, Laing) reports, "A bipartisan pair of lawmakers on Tuesday announced a bill to create six pilot 'intelligent transportation systems' they say will use technology to ease transit woes in cash-strapped American cities. Reps. Mike Rogers (R-Mich.) and Russ Carnahan (D-Mo.) said their 'Smart Technologies for Communities Act' would make improvements to transportation that federal and state governments could not otherwise afford." Notably, "the bill would create pilot programs in six cities to test whether technologies such as cars with crash sensors, bridges that can sense stress from vehicle weight, electronic toll systems and live updates to commuters improve overall commutes."


The Detroit News (3/30, Shepardson) reports the bill "would provide grants to make 'Intelligent Transportation Systems' a reality." They support "spending $1.2 billion over six years" on the initiative. The News says "the pair will tout their bill along with Intelligent Transportation Society of America CEO Scott Belcher in a press briefing Wednesday." Their bill has the support of "the Alliance of Automobile Manufacturers and its members, including General Motors Co., Ford Motor Co. and Chrysler Group LLC." It would "create a pilot program in up to six communities across the country to serve as model deployment sites for large-scale installation and operation of ITS to improve safety, mobility and the environment on the nation's highways."

Real Energy, Real Jobs

By looking at the title, for a second I thought that I wrote this article and forgot about it, but the Real Energy, Real Jobs article was written by Robert Bradley Jr., CEO and Founder of the Institute for Energy Research and author, Capitalism at Work: Business, Government, and Energy.

Indeed Energy is Big Business and critically important for the US, Hawaii and indeed all civilization. For each location, there is an optimum mix of energy options for abundant, affordable energy, energy jobs and energy profits. There are many sub-optimal mixes that may lead to huge profits, short-term jobs, and unreliably and expensive energy. You can read some of these in Bradley's article.

In addition to the points raised in the article Real Energy, Real Jobs, my own research has revealed that:
  • Denmark: 20% of the electricity is from wind, but much of it is exported at no cost to Norway in return for baseload electricity when the wind does not blow!
  • Spain: For every 1 green job financed by Spanish taxpayers, 2.2 jobs were lost as an opportunity cost. Since 2000, Spain spent $753,778 per “green job.”
  • Germany: Green jobs created by government actions disappear as soon as government subsidies end.
  • Texas: After 30 months, countless TV appearances, and $80 million spent on an extravagant PR campaign, T. Boone Pickens has finally admitted the obvious: The wind energy business isn't a very good one. The Dallas-based entrepreneur, who has relentlessly promoted his Pickens Plan since July 4, 2008, announced that he's abandoning the wind business to focus on natural gas. (Wall Street Journal quote.)

Nuclear Power Plant ... Oxymorons and Solutions

The Economist has a useful tool for looking up which have nuclear power and how much electricity they produce in a year. The U.S. leads the pack.

One of the oddities of nuclear power is that some countries like Greece are strongly opposed to nuclear power, yet less than 100 miles away their Bulgarian neighbors already have nuclear power plants ... This reminds me of Hawaii with its nuclear power plant constitutional prohibition and the 15 nuclear submarines home ported in Pearl Harbor.

The difficult management of a failing power plant due to major force of nature as witnessed in Japan makes a strong case for locating them on off shore floating platforms (e.g., refurbished decommissioned air carriers.) These platforms, like off shore rigs can be manned as required by helicopter flights but they can be engineered for self power and management by remote control (like the unmanned drones of the air force.)


In the extremely rare care of nuclear reactor failure the floating platform can be de-anchored and de-tethered, and then robotically powered away from populations. This plan offers significant economic, safety and psychological benefits. Perhaps the state of Georgia should look into a floating platform 10-20 miles out in the Atlantic among its alternatives for locating a very large nuclear power plant.

Higher Gas Prices. Go for Trains and Electric Cars?

Fuel prices are trending upward in a hurry due to world events.

Local governments, including Honolulu's also are increasing fuel taxes.


The damage to people's wallets and family budgets will worsen.

So is it more economical to switch to a train or an electric car? This is definitely not a good choice in Honolulu.

Hawaii has by far the highest price per kilowatt-hour of electric power in the nation. The current price on Oahu is about 28 cents per KWh or 230% higher than the U.S. national average. AAA reports today's regular gas price in Honolulu at $4.084 per gallon or 15% higher than the U.S. national average.


Over 75% of the electric power on Oahu is produced by oil.


So it is pain at the pump and pain at the plug. But in relative terms, gasoline is a bargain. Honolulu pays a 15% premium on gas and a 230% premium on electricity.

This has two important implications for transportation in Hawaii:
  1. The 100% electric car Nissan Leaf is rated by EPA at 99 MPGe (miles per gallon equivalent) assuming the average price of 11 cents per KWh in the US. This reduces to about 40 mpg in Hawaii because power is 230% more dear. As a result, the Nissan competes with similarly fuel efficient Ford, Honda, Hyundai and Toyota hybrids which cost less and have a range of 400 miles instead of 100 miles.
  2. The operating cost and pollution impact of the proposed rail will be staggering because it draws several megawatts of electricity, runs almost empty for 16 out of 20 hours of its daily operation, and has a minimal benefit on traffic congestion.
(Of course by now it is clear that rail is the way for billions of taxes to be reallocated to special groups and politicians -- both of them pushing it madly.)
