It has been argued that from an entire cycle standpoint grains deliver the most energy to a human body per Btu of energy used to produce it. Meat is much less energy efficient. I heard a comparison made one time of energy efficiency of bike riding vs. gas guzzler driving. The author of the comment calculated all the energy required to produce a pound of beef steak, and how far the bicyclist could go on the energy derived from that pound of steak. He then compared the amount of energy required to drive an old gas guzzling Buick that same distance. From the standpoint of the entire energy consuming/producing cycle to move that particular distance, the Buick was more efficient!
If say the Power Company operates at about 40% Thermal Efficiency, and a fuel-efficient automobile operates at about 30% Thermal Efficiency, and a "gas-guzzler" operates at about 20% Thermal Efficiency, and a human being operates at about (depending what he's doing) 10% Thermal Efficiency, and wheat grows at about 2% Thermal Efficiency, then what you're saying is that everybody should take the cow to work?
You need to take the Power Company to work!
You need to take the wheat to work!
