How Does Energy Resource Depletion Affect Prosperity ...

It has been proposed that energy resource depletion and declining energy return on investment (EROI) can disrupt modern, prosperous lifestyles. This is because such lifestyles are dependent on abundant, low-cost energy supplies, to date supplied by fossil energy. We illustrate a mathematical structure by which to analyze the impacts of energy depletion as it affects all sectors of the economy ...

Oil Sands: Water Management | Natural Resources Canada

All major energy production requires water. Water requirements for oil sands production vary depending on the technology used for extraction. Water is used in oil sands extraction to help separate extra-heavy crude oil, also known as bitumen, from the sand, clay and water that make up the oil sands.
