Wind Speed Variability Sample as Reported in a Presentation by Renewable Energy Laboratory:

Civil Engineering Professor Panos D. Prevedouros, PhD discusses his opinions on infrastructure issues with emphasis on the City and County of Honolulu.
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."
The March 5, 2011 issue of The Economist states that USA’s debt to China at the end of 2010 in the form of U.S. Treasury notes was 30% higher than had been thought. China holds $1.19 Trillion in U.S. Treasury notes and Japan holds $882 Billion of the same.
So this form of debt of the USA to China and Japan comes to $2,072,000,000,000.
Let’s try to get a handle on this. The U.S. has about 140 million taxpayers (indeed, less than half of the population files for federal taxes) and 20% of them pay minimal amounts. That leaves about 100 million taxpayers holding this bag.
What’s your share? $20,720!
The average U.S. taxpayer owes China and Japan about $21,000. Your rate will vary depending on your income: If you make $50,000 you pay roughly 15% of that to the IRS, but if you make $200,000 you pay 30% of that to the IRS.
We got ourselves into a deep (and deepening) hole. There is one way to lessen this: Devalue the dollar to ½ its current worth. In this way, our average taxpayer debt to China and Japan becomes about $10,000.
Unfortunately at the same time everything at Walmart and at the gas pump doubles in price. Overnight the gas price goes from $4 to $8 per gallon. And a large portion of the population becomes impoverished.
Twenty plus years of tax and spend and entitlements will come full circle. Entitlements are the wrong way to pull people out of poverty. They ballooned the national and local debts. And the poor will pay the heaviest price no matter how hard “socially minded” decision makes have tried to help them.
HAWAII’S RENEWABLE ENERGY MANDATES, and HOW IT AFFECTS EVERYONE
Presentation to Hawaii Conservatives in Hilo, Hawaii, on February 27, 2011
We were honored to be addressed by two distinguished speakers at our Feb 27 forum: Michael Kaleikini, manager of Puna Geothermal Ventures, on “Geothermal Energy in Hawaii" and Dr. Panos Prevedouros, Professor of Civil Engineering at University of Hawaii, on “Statewide Implications of the Mandates". Questions were entertained after both speakers concluded.
Mr. Kaleikini described the history and present role of Puna Geothermal Ventures production on the Big Island. The first geothermal wells were drilled in the 1960s in Kapoho. In 1981, the state had a pilot program to prove the viability of geothermal energy production. The plant produced 3 MW of power, and was designed to last 3 years but stayed in production for 6-7 years. In 1993 PGV came on line, the first commercial geothermal plant in Hawaii. It was located on the lower rift zone of Kilauea because “ that is where the resource is."
It uses a hybrid / combined cycle where steam and hot water (brine) comes up in production wells from about 6000 ft down, is used to drive turbines for power generation, and then is returned underground via injection wells. It is a 100% renewable and closed-loop system. Today there are 6 production wells and 4 injection wells in operation.
PGV has 34 full-time employees and contractors. The State of Hawaii owns the mineral rights, and PGV pays royalties to the state and county. Proceeds from those royalties have gone to support the Hele-on bus, lifeguards, park maintenance and other public projects. PGV is owned by ORMAT Corporation, head quartered in Nevada, with geothermal projects located around the globe. They are the only vertically integrated geothermal energy company, involved with drilling, manufacturing of turbines and associated specialized geothermal equipment and electrical power production.
Currently PGV is under contract with HELCO to provide 30MW of electricity, and is permitted to go to 60 MW. They provided 17% of the Big Island total electricity last year, and they just recently signed a new contract to provide an additional 8MW at a fixed price not tied to the price of oil (as their present contract is).
Dr. Prevedouros then addressed us.
He pointed out that Hawaii had the most expensive electricity in the nation, double that of California and 3 times the national average (36 cent per kw-hour on the Big Island). Our energy sources as a state are 77% from oil, 15% coal and the rest “renewable". The Big Island is about 68% oil and 32% renewable, of which geothermal is about 18% and wind 11%. The state is therefore vulnerable to the availability of oil. American national policy has supposedly been to reduce our need for oil as an energy source, but through many different administrations little progress has been made. As Jon Stewart has said about this, "Fool me once shame on you. Fool me twice shame on me. Fool me 8 times...am I a @#$% idiot?"
Hawaii has had "renewable energy" mandates since 2001. In 2008, the Lingle administration increased the goal to be 70% "clean" energy by 2030, of which 40% is to be in electrical production and 30% from efficiencies and alternate fuel sources. However, if we kept present oil and coal usage constant, and massively increased production of biomass, H-power (trash), geothermal, wind and solar, we would still not meet the projected demand in 2025.
Part of the problem is how does one define "clean"? Is it energy that reduces greenhouse gases, hazardous chemicals (like mercury and sulfur dioxide), environmental degradation associated from production (like mine tailings and drilling leaks or cutting forests to plow more fields for biofuels), or the pollution hazards of combustion (such as trash)?
In addition, it is true that cheap energy = growth, and this is essential for our economic system. Most of our economic growth is tied to natural resource extraction, which will be limited if resources are not renewable. However, that does not apply to renewable sources of energy, including geothermal, hydro, solar, trash burning, nuclear and potentially algae to fuel.
What is needed is a realistic approach, not pipe dreams", Dr. Prevedouros stated.
In Spain, it was found that for every 1 "green job" financed by the Spanish taxpayers, 2.2. jobs were lost from the overall economy.
In Germany, "green" jobs financed by the government disappeared as soon as government subsidies ended.
One electrical vehicle is the equivalent of a small house in power consumption.
He himself had a solar system on his roof at home, but the $14,000 system cost him a net $4000 only after state and federal subsidies
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. He's abandoning the wind business to focus on natural gas. On a national scale, it is expected the US will transition heavily from present 49% coal/21% natural gas to 40% cheap natural gas/25% coal.
Denmark, the poster child of wind energy production at 20%, has to sell much of its peak power to neighboring Norway and buy from them a steady base load in return, as wind is incapable of a steady supply.
Wind cannot work in Hawaii, as we have no nearby neighbor for such a deal. What are we going to do, turn the elevators on in Waikiki when the wind blows, then turn them off when it stops? Impossible."
Turning food to energy is no good either. " Food prices world wide are rising as a result. " Former vice president Al Gore said that he regrets supporting first generation corn-based ethanol subsidies while he was in office. Gore said his support for corn-based ethanol subsidies was rooted more in his desire to cultivate farm votes for his presidential run in 2000 than in doing what was right for the environment: "It is not a good policy to have these massive subsidies for first-generation ethanol".
Dr. Prevedouros stated "Energy policy should be grounded in realism, and should pursue the ‘Double A's’: Abundant and Affordable."
Energy policy in the US has consisted of fantasies: fantastical claims of imminent energy independence or imminent technology breakthroughs. Wind and solar power are unreliable for baseload electricity; even with subsidies, they do not scale up enough to reduce fossil fuel use significantly.
Governments simultaneously spend too little and too much on clean-tech. Too little on research, development and demonstration of new technologies, and too much subsidizing the commercialization of older technologies that don’t stand on their own. If clean-tech companies can make a profit making subsidized technologies, why would they try to invent anything better?
So what makes sense for Hawaii?
Clarity of goals is needed
On the Big Island, increase geothermal for complete electrical supply. He notes the geothermal reserve on Earth is 70 million QUADs (hot rock only) but the USA needs only 100 QUAD/yr. In the Philippines they already use 27% geothermal, and in Iceland 100% for electrical power.
On Oahu and Maui, increase trash burning and clean coal as electrical power sources. Australia has a resource of over 75 billion tons of high quality and inexpensive coal: low in sulfur and reduced ash, high in energy content. India recently contracted to purchase 8 billion tons and was building port facilities for that alone. Honolulu should consider that as an alternative to oil.
On Oahu, increased "green bin" biomass use for methanol vehicle fuel, cooking grease for biodiesel, and long-term use of biofuels from algae. Algae have the potential of being both renewable, greater affordable energy potential than wind or solar, and are attracting serious investment.
Also not out of consideration would be nuclear. The Nuclear Regulatory Commission is processing permit applications for at least 26 new power plants in U.S. Gallop Poll shows 62% favor the technology, and Obama wants to triple the amount of loan guarantees for new reactors. The current price tag for a large nuclear plant: $6-8 billion. Traditional nuclear power plants are not suitable for Hawaii. However, there is the possibility of extending lengthy power cables to decommissioned Navy vessel with small reactors (50 MW). Also promising are the "micro-reactors" such as the Toshiba 4S (Super Safe, Small and Simple) nuclear power system able to supply 10 MW of electricity for 30 years without any new fuel. The plant is simply buried and then dug up and replaced when used up.
The achievable goal would be to bring Hawaii’s overall present 75% oil usage down to 40% by 2040.
We consequently are united in opposing the construction of an elevated heavy-rail system through historic downtown Honolulu and strongly urge consideration of a less destructive and more neighborhood-friendly system.

Everyone must learn about the realities of the city's plan and the steamroller process that is propelling it. There's much more to come.
As the City and County of Honolulu proceeds with its analysis of O'ahu's transportation future and holds community meetings to solicit public input, the cost of a proposed fixed guideway is a common topic of discussion.
As is their role, the professional planners and engineers involved in this Honolulu High-Capacity Transit Corridor Project are gathering data, making analyses and evaluations, and preparing recommendations for the City Council, which will make the final selection of a transit alternative later this year. The planners and engineers are envisioning a system where money is not a primary factor, a transit network that accommodates all needs well into the future, a world-class fixed guideway that rivals those of the great cities around the world.
That is not the world in which we live. It is my responsibility to balance needs with resources. This has meant that we've had to make some tough fiscal decisions over the past year-and-a-half, foregoing the nice-to-have for the need-to-have.
The transit system the city ultimately will support will meet our immediate needs and our budget, estimated at around $3 billion. This is called a "minimal operable system" in the parlance of transportation engineering. Yes, a multifaceted, multimodal approach to solving our growing traffic mess falls within the need-to-have, but I want to be careful that we do not exceed our financial limits.
If revenues from the general excise tax surcharge provide more money [1] for our transportation coffers, or if private partnerships [2] generate a major infusion of cash, or if we receive any financial windfalls [3] for mass transit, then we can consider spending more money to expand the system.
Until then, I will continue to insist that we live within our means.[4]
Mufi HannemannThe city has not come out and explained these requirements to the public. Therefore, it is time for the city council and the media to ask for clarity.
Here are some questions to ask the city to get them to explain where they are in the FTA New starts process:
1. Please explain the difference between the Pre-Award Construction Authority that is applied when Honolulu receives its Record of Decision and the construction authority that comes with a Letter of No Prejudice?
2. Please tell us when you are going to apply for permission to enter into Final Design? Please tell us what the city needs to do in order to make this application?
3. Please tell us what will be accomplished in Final Design and why it will take almost a year to complete?
