Searching for New Sources of Energy and Looking in all the Wrong Places

Recently, Frank Luntz, a pollster, corrected a Fox News pundit, who stated that Americans were in favor of drilling for more oil. Luntz stated that Americans did not want to drill for more oil, they “wanted to explore for new energy sources.” Personally, I believe this is a distinction without a difference; however, it appears that the liberals and environmentalists have convinced Americans that drilling equals environmental apocalypse. So, following the lead of Albert Einstein, I decided to perform some “thought” experiments to see what sources I could find and thereby meet the needs of my fellow citizens, who currently are sitting on 86 billion barrels of oil, with 85% of it off limits to drilling (USA Today, June 13, 2008, pg 2A).

Serendipitously, I came across a 2006 USA Today article “Feds: Obesity Raising Airline Fuel Costs,” in which USA Today suggests, based on a 2000 Center for Disease Control study, that the 10 additional pounds gained by the average American in the 1990s, costs the American airlines an additional 350 million gallons of fuel per year and produces 3.8 million additional tons of carbon dioxide. The article states that this represented a fuel price increase of $275 million. I was “flabbergasted,” pardon the pun, which resulted in an epiphany. What if I could turn “flab” into “gas?”

First, I needed to confirm some facts. I had to determine the scope of the opportunity. First, I checked the projected benefits of simply reducing the cost of airline fuel. I found it circumspect that 350 million gallons of fuel could cost only $275 million dollars (78.9 cents per gallon). Lo and behold, to my surprise, the International Air Transport Association (www.iata.org) tracks the weekly price of aviation fuel. In 2000, a gallon of gas traded at 87 cents per gallon, which compares favorably to that reported). Even more surprising, the cost of a gallon of aviation fuel on June 13, 2008 was listed as $4.03 per gallon. Then I knew I was really onto something. The potential savings from solving this problem alone was worth almost 5 times the originally reported cost savings – $1.27 billion.

But were there other benefits? Several came to mind: reduction in food cost, better health were obvious… how about generating energy from the fat stored in the bodies of all these overweight individuals.

Additional research was required to estimate the additional benefits that could accrue to my fellow Americans – those sitting on 86 billion barrels of oil, 85% of which is off limits to drilling (are you starting to see a theme here). Here is what I learned:

- 65% of adult Americans are overweight or obese (source: CDC). This is defined in terms of body mass index (BMI), but it is generally accepted that it would include individuals who are at least 20% above their ideal body weight. Using the mid-point weight, by BMI, an average weight of 147 pounds for a 5 foot, 9-inch height individual was calculated. Using the 20% factor, “overweight or obese” was determined to be 30 pounds of fat.

- 75.4% (226.3 million) of all Americans (299.4 million) in 2006 were older than 18 (source: Census Bureau).

- Various newspaper reports state that the average American (those sitting on 86 billion barrels of oil, 85% of which is off limits to drilling) consumes 4,000 calories per day. According to the calculator on www.health.com, a 147-pound person doing office work and light reading 16 hours per day and sleeping 8 hours per day, requires 2,399 calories per day. Other sources indicate a minimum need of 2000 calories per day. These statistics are comparable to those reported by the Food and Agriculture Organization (FOA) of the United Nations which states that the average American consumes 3,790 calories per day compared to some third world countries that consume 2,020 calories per day. Conservatively, Americans consume at least 1,500 calories each day more than they need.

- According to www.health.com, 1 hour of vigorous walking exercise consumes about 368 calories. For purposes of this analysis, I will assume it is all fat; clearly that is not the case, but this is a blog not a scientific journal.

- There are 9 calories per gram of fat (source: www.wikipedia.com ). There are 1000 grams in one pound (source: basic high school education, circa 1967).

- According to a University of Washington Cooperative State Research, Education, and Extension Service (CSREES) study (March 2008), Adam Drewnoski, checked the prices of 372 foods sold at local supermarkets in the Seattle, WA, area, comparing the prices with calorie density. High calorie density foods include things like peanut butter and granola; low-density foods included things like fruits and vegetables. “Based on a standard 2000 calorie diet, the researchers found a diet consisting of calorie dense foods costs $3.52 per day, but a diet consisting primarily of low-calorie foods, costs $36.32 a day. The average American eats a variety of foods, throughout the day, spending $7 per day.” Further, the study reports that during a the two year study period, the price of high –calorie foods decreased by 1.8% and the price of low-calorie foods increased 19.5 percent. While the $7 per day seems high, it does compare favorably to the number reported in Agriculture Fact Book, 2000 – 2001, food expenditures in the United States were $2,964 per capita or $8.12 per day, which represents a higher caloric intake than 2000 calories per day. Based on this data, I non-scientifically extrapolated the data to state that the cost of 200 calories of food is $0.43 (200 x $8.12 per day / 3,790 calories per day).

So, what can you deduce from all this? Assuming the 147 million average Americans, who are either overweight or obese, (and sitting on oil, etc) were to walk one hour per day five days per week and reduce their food consumption from almost 4,000 calories per day to 2,500 per day, they would:

- Lose 4.4 billion pounds of fat over a period of 1.3 years, resulting in better health and a feeling of self worth due to their accomplishment.

- Save the American airline industry ~ 800 million gallons of fuel per year (350 million gallons per 10 lbs multiplied by 30 pounds per person and divided by 1.3 years) costing $3.2 billon dollars (800 million gallons multiplied by $4.00 per gallon), but probably an overstatement, because the cost of fuel would most likely come down due to supply / demand … so discount this by a third, and reduce the savings by $1 billion a year to $2.2 billion). This is the equivalent of one-day’s energy consumption for the whole United States (20 million barrels per day at $137 per barrel, as of this writing).

- Reduce individual adult food cost by at least 32%, assuming a 2,500-calorie diet (i.e., (3,790 calories – 2,500 calories)/(3,790 calories)) or a savings of $948 per year per adult. Assuming a family of four, comprised of two adults and two minors, this represents a family savings of almost $1,900 per year or 4.5% of the average American family income (assumed to be $42,000). Not factored into the calculation is the costs required to produce the food which can be 12 to 100 times as energy intensive as the calories consumed (i.e., it requires 12 calories of energy to produce 1 calories of corn; 96 calories of energy to produce 1 calorie of beef).

- Reduce carbon dioxide emissions by 9 million tons per year. The US electric utility industry releases 2.8 billion tons of carbon dioxide per year (source: Washington Post). Airline savings would equate to a little more than 1 day of carbon dioxide savings.

- Even though it is beyond the scope of this article and will be the subject of another blog, if the walking energy expended by these 147 million Americans was harnessed on treadmills and converted to useful work (assuming a conversion ratio of 0.7), then we could generate approximately 85 watts per person or approximately 12,500 Megawatts (Mws) in total capacity. Assuming each person walks1 hour per day, five days per week, for 1.3 years, this is equivalent to approximately 50,000 Mw-hr in generation. This is approximately 4 days of generation from a 600 Mw coal fired fossil unit.

In spite of these benefits, I suspect that the average American (who is currently sitting on 86 billion barrels of oil, with 85% of it off limits to drilling) will not choose to capture them. Instead, they will use the additional calories to generate hot air, the energy content of which cannot be captured for useful purposes, and only will contribute to global warming and the eventual energy death of the world. That assumes that the flawed ideas and inaction generated by their talking doesn’t destroy it first.
