Concerns about our oil supply has hit home when he must stop at the gas pump and fill our cars more than $ 3.00 a gallon. This is a blow to our pockets and is unlikely to end soon. Above and beyond the many theories about the political reasons for this trend are the facts. The era of cheap oil is over. The effects of higher oil prices are felt most directly in the rising cost of oil we use to heat our houses, petrol we use to run our cars and electricity to power its lights. Oil companies such as, for Western Pipeline Corporation, using new technologies to further develop the existing production wells to optimize production to offset the effects of high oil prices.
There is much less aware of how strongly our food system depends on cheap oil market. Oil fuels our food from fertilizers to pesticides. It feeds on the farm tractors and trucks to take on the market. Markets are any of your local grocery store for food processing plants enormous. Oil fuels plant food processing, food packaging plant and the truck carrying his remains off to the landfill.
Only 21 per cent of overall food system energy is used in agricultural production, 14 percent goes to food transport, 16 percent for processing, 7 percent for packaging, 4 percent to food retailing, 7 percent for restaurants and caterers, and 32 percent to home refrigeration and preparation.
Since the 1950s, agricultural production relied on fertilizers to replace soil nutrients. Production of nitrogenous fertilizers relies heavily on natural gas to synthesize nitrogen air. Oil is necessary both to mine, manufacture and transport these fertilizers around the world. China is now the top consumer fertilizer with consumption growing at over 40 million tons in 2004.
The world grain production tripled during the last century. New grain demand has been met primarily by raising land productivity through higher yielding varieties of crops conjunction with more oil-intensive mechanization, irrigation and fertilizer use, rather than by expanding cropland.
Processed foods now account for three quarters of the worldwide turnover of total food. A bag of two pounds of breakfast cereal burns the energy of a half-gallon of gasoline in his cooking. Breakfast cereals Processing uses about five times more energy is contained in the cereal itself. Together, the food in the United States uses about ten calories of fossil energy for every calorie of food energy it produces.
In 1940, the average farm in the United States produced 2.3 calories of food energy for every calorie of fossil energy used. In 1974 (the last year research has been done), this ratio was 1:1. In 1940 we received approximately 100 barrels of oil back for every barrel of oil, we have spent to get it. Today, each barrel invested in the process returns only ten. Not only is it costing us more to get the oil we are getting a lot less energy to form the calories of oil.
