Our Energy Future

By Capt. Dallas

These are exciting times. Political, economic and technological conditions have combined to create a true opportunity for advancing our energy choices. Fossil fuels price will fall back some but our vulnerability as a nation to “black” mail will drive continued alternate energy development. The “black” being black gold controlled increasingly undesirable nations.

Everyone has his or her own opinion of the right way to approach changing our energy economy. Being pragmatic, I try to look at all the options. Of all the options we have, each has benefits and each has disadvantages.

Bio-fuels are the greatest example of the conundrum we face. Alcohol fuel is made from renewable resources. It is clean burning and works with our internal combustion engines. Big benefits! Alcohol has only 75% of the energy of gasoline, it takes energy to produce, it is a solvent that reduces engine life and food/feed crops have to be diverted for it to provide a significant portion of our energy needs. Pretty big disadvantages!

The biggest disadvantage of bio-fuels is the last, competition with our food sources. Biomass is non-competitive to a point, but eventually energy producing acreage will compete win food production acreage.

Solar energy has the advantages of being clean and renewable. The disadvantages are less obvious but are there. Solar energy using photovoltaic panels has over thirty-five years of history and is only now reaching 20% efficiency in conversion. Like other electronic technologies, solar cell efficiency and prices will change dramatically. Investing billions into huge solar energy plants will be a hard sell. With a recent record of a PV cell reaching 40.3 percent efficiency, more than twice the efficiency of available mass produced cell it is a harder sell at this time.

One good thing about the new high efficiency PV cell is that solar technology is close. Since 40% is approaching maximum efficiency reducing chances that radically higher efficiencies will be available any time soon. Price reduction of the higher efficiency cells should still be a concern of energy investors.

Wind power has made great leaps in efficiency in the past twenty years. Windmills rated for five Mega Watts (MW) each are in production. These new windmills or wind-turbines if you prefer can produce energy at lower wind speeds extending their useful range. With current power outputs and useful life spans of twenty-five to thirty years they are a good investment. While wind power technology is sure to improve the cost per MW is low enough with current technology to pay for the investment. All great advantages for wind power. The disadvantages are really only two. The not in my back yard (NIMBY) mentality, that limits areas where it can be used and wind power needs wind to work. In conjunction with other power plants wind can provide a large portion of our power needs but not own its own.

Tidal and wave power, the most over looked of the alternate power sources have quietly proven themselves and are poised to be energy players. Tidal has forty years of proven reliable service at the La Rance power station in France. Wave power has less of a track record but has proven reliable in initial smaller scale tests. The advantages of tidal and wave energies is that they are very cost effective. The disadvantages are they can effect the environment and hinder shipping in some applications. Further disadvantages are that acquiring ideal lease for areas are difficult and there is only a limited selection of ideal area to be considered.

Nuclear power technology has improved over the years as well. Nuclear power’s advantages are clean, reliable, stable and cost effective power. The disadvantages are catastrophic disaster (low probability but a big concern), security and waste disposal. Due the first list disadvantage the NIMBY crowd are highly vocal.

Hydrogen, which is not really a source of energy just a medium of storing energy, has the advantages of being clean and versatile. Hydrogen can fuel a large variety of existing engines and heat sources. It is perfectly suited for fuel cells which is a much more efficient method for using this fuel. Disadvantages are it takes energy to produce, is more difficult to store and it is explosive as all hell.

Now is the fun part of this article for me! Expressing my option. Despite its disadvantages hydrogen will be the portable fuel of our future. Hydrogen is a far to efficient and clean a fuel to be ignored. Safe, reliable storage systems for hydrogen are developing rapid because of its potential. Hydrogen also will extend the useful areas for wind and tidal/wave power generation. Areas remote from civilization and electrical grids can be used to produce hydrogen. Hydrogen will also increase the overall efficiency of nuclear power plants and other manufacturing processes with waste heat. Thermolysis, a heat and chemical hydrogen manufacturing process is perfectly suited for using the waste heat of various processes.

Hydrogen stored in plentiful energy times can be used to make energy produced by wind, solar and tidal/wave stand-alone power sources. For example: in a solar home, hydrogen produced in the day will produce electricity at night through fuel cell conversion. Think of hydrogen as the near ultimate battery. While a solid-state battery would be a huge boon to mankind a gaseous/liquid state battery ain’t all that bad!

Our energy future will require various sources and responsible application to maintain a healthy economy and meet our goal of energy independence. These are the most exciting times of our energy lives.

MANDATORY RENEWABLE ENERGY – THE ENERGY EVOLUTION –R12

In order to insure energy and economic independence as well as better economic growth without being blackmailed by foreign countries, our country, the United States of America’s Utilization of Energy Sources must change.
"Energy drives our entire economy.” We must protect it. "Let's face it, without energy the whole economy and economic society we have set up would come to a halt. So you want to have control over such an important resource that you need for your society and your economy." The American way of life is not negotiable.
Our continued dependence on fossil fuels could and will lead to catastrophic consequences.

The federal, state and local government should implement a mandatory renewable energy installation program for residential and commercial property on new construction and remodeling projects with the use of energy efficient material, mechanical systems, appliances, lighting, etc. The source of energy must be by renewable energy such as Solar-Photovoltaic, Geothermal, Wind, Biofuels, Ocean-Tidal, Hydrogen-Fuel Cell etc. This includes the utilizing of water from lakes, rivers and oceans to circulate in cooling towers to produce air conditioning and the utilization of proper landscaping to reduce energy consumption. (Sales tax on renewable energy products and energy efficiency should be reduced or eliminated)

The implementation of mandatory renewable energy could be done on a gradual scale over the next 10 years. At the end of the 10 year period all construction and energy use in the structures throughout the United States must be 100% powered by renewable energy. (This can be done by amending building code)

In addition, the governments must impose laws, rules and regulations whereby the utility companies must comply with a fair “NET METERING” (the buying of excess generation from the consumer at market price), including the promotion of research and production of “renewable energy technology” with various long term incentives and grants. The various foundations in existence should be used to contribute to this cause.

A mandatory time table should also be established for the automobile industry to gradually produce an automobile powered by renewable energy. The American automobile industry is surely capable of accomplishing this task. As an inducement to buy hybrid automobiles (sales tax should be reduced or eliminated on American manufactured automobiles).

This is a way to expedite our energy independence and economic growth. (This will also create a substantial amount of new jobs). It will take maximum effort and a relentless pursuit of the private, commercial and industrial government sectors’ commitment to renewable energy – energy generation (wind, solar, hydro, biofuels, geothermal, energy storage (fuel cells, advance batteries), energy infrastructure (management, transmission) and energy efficiency (lighting, sensors, automation, conservation) (rainwater harvesting, water conservation) (energy and natural resources conservation) in order to achieve our energy independence.

"To succeed, you have to believe in something with such a passion that it becomes a reality."

P.S. I have a very deep belief in America's capabilities. Within the next 10 years we can accomplish our energy independence, if we as a nation truly set our goals to accomplish this.
I happen to believe that we can do it. In another crisis--the one in 1942--President Franklin D. Roosevelt said this country would build 60,000 [50,000] military aircraft. By 1943, production in that program had reached 125,000 aircraft annually. They did it then. We can do it now.
The American people resilience and determination to retain the way of life is unconquerable and we as a nation will succeed in this endeavor of Energy Independence.

The Oil Companies should be required to invest a substantial percentage of their profit in renewable energy R&D and implementation. Those who do not will be panelized by the public at large by boy cutting their products.

Solar energy is the source of all energy on the earth (excepting volcanic geothermal). Wind, wave and fossil fuels all get their energy from the sun. Fossil fuels are only a battery which will eventually run out. The sooner we can exploit all forms of Solar energy (cost effectively or not against dubiously cheap FFs) the better off we will all be. If the battery runs out first, the survivors will all be living like in the 18th century again.

Every new home built should come with a solar package. A 1.5 kW per bedroom is a good rule of thumb. The formula 1.5 X's 5 hrs per day X's 30 days will produce about 225 kWh per bedroom monthly. This peak production period will offset 17 to 2

4 cents per kWh with a potential of $160 per month or about $60,000 over the 30-year mortgage period for a three-bedroom home. It is economically feasible at the current energy price and the interest portion of the loan is deductible. Why not?

Title 24 has been mandated forcing developers to build energy efficient homes. Their bull-headedness put them in that position and now they see that Title 24 works with little added cost. Solar should also be mandated and if the developer designs a home that solar is impossible to do then they should pay an equivalent mitigation fee allowing others to put solar on in place of their negligence. (Installation should be paid “performance based”).

Installation of renewable energy and its performance should be paid to the installer and manufacturer based on "performance based" (that means they are held accountable for the performance of the product - that includes the automobile industry). This will gain the trust and confidence of the end-user to proceed with such a project; it will also prove to the public that it is a viable avenue of energy conservation.

Installing a renewable energy system on your home or business increases the value of the property and provides a marketing advantage.

Nations of the world should unite and join together in a cohesive effort to develop and implement MANDATORY RENEWABLE ENERGY for the sake of humankind and future generations.
The head of the U.S. government's renewable energy lab said Monday (Feb. 5) that the federal government is doing "embarrassingly few things" to foster renewable energy, leaving leadership to the states at a time of opportunity to change the nation's energy future. "I see little happening at the federal level. Much more needs to happen." What's needed, he said, is a change of our national mind set. Instead of viewing the hurdles that still face renewable sources and setting national energy goals with those hurdles in mind, we should set ambitious national renewable energy goals and set about overcoming the hurdles to meet them. We have an opportunity, an opportunity we can take advantage of or an opportunity we can squander and let go,"
solar energy - the direct conversion of sunlight with solar cells, either into electricity or hydrogen, faces cost hurdles independent of their intrinsic efficiency. Ways must be found to lower production costs and design better conversion and storage systems.
