For the past century we have had free energy in the form of gas and diesel oil. Let me illustrate. Suppose you need the energy to move 1,000 pounds of corn 10 miles to market. Here are three ways to do it. All calculations are roughly adjusted to current dollars.
- Hire a porter at $200 per day for 20 days to carry it on their back at 50 lbs per 20 mile round trip. Cost = $4,000.This method was used for several millennia.
- Hire a driver, wagon, and team of horses for one day to make the 20 mile round trip. Cost = $400.This method was used for many centuries.
- Hire a driver and truck at $2/mile which includes driver, deprecation, repairs, fuel and oil. Cost = $40. This method has been used for a less than a century. This is only 1% of the cost of the most prevalent method used in the history of man.
By historical standards, $4/gallon of gas is basically equivalent to free energy. Think about that the next time you fill your car and stop by the grocery store to pick up Gatorade as you take the kids to soccer practice.
During most of the history of mankind, people spent 70%-90% of their time to get food. The rest of the time was spent getting clothing and shelter. When they weren’t totally exhausted, they made babies to help them with the work. The only soccer the kids got was kicking a squash around when their parents weren’t overseeing their weeding and watering.
Because of free energy, we have basically the equivalent of free food – it costs us much less than 10% of the time we expend for work and other activities. Here at Backyard Farming, we advocate spending much more time and energy to generate food. Backyard farmers have an appreciation for food that has been lost in our society. One of our goals is to restore that appreciation in more people. We encourage you join our efforts and be an advocate for backyard farming.
