Trivial Corn Stove Questions
- Can corn farms raise enough corn to provide America's total energy by
year 2030? For surprising answer, go to bottom.
The International Energy Agency states that in 2030 the world will
consume more than 115 million barrels of oil per day, up from the
current 85 million barrels per day.
100 million acres of corn in the US x 150 bu/acre x 2.8 gal ethanol/
bu = 42 trillion gal/yr
100 million barrel x 365 day/yr x 42 gal/bar = 1533 trillion gal/yr
Energy For MECHANICAL SYSTEMS
* The U.S. non-residential buildings inventory includes more
than 5 million buildings.
* Commercial buildings consume 17% of all energy used in the
U.S. (nearly 17 Quads in 2004), including 34% of all electricity
(about 4.2 Quads in 2004).
* Mechanical/HVAC systems are often the largest consumers of
electricity in commercial buildings, accounting for 50% to 70% of
total energy costs.
* The estimated 130 million mechanical rooms in the U.S. were
built in a time of abundant energy and fresh water in favorable
Residential, commercial, and industrial each use equal amounts of
energy (30-35% each)
Water heating cost is 10-30% of total residential energy use.
Each Power plants will use more energy than it delivers.
Fossil power plants deliver about 25% of the energy consumed.
ANSWER: Feel free to crunch the numbers above.

a. corn yields continue at 150 - 300 bu per acre
b. increase US corn acreage back to the corn acreage planted in year 1910.
c. Heat with whole kernel shelled corn. Use corn ethanol for
d. politics, governments and war do not interfere with corn production
