Energy cost and availability will likely become an important factor affecting future natural resource management. Recent information suggests that world oil production will peak within a decade or two implying that demand will outstrip supply and energy costs will increase significantly and become more scarce in the coming decades. Some have augured that additional discoveries will provide abundant oil well into the future. But most estimates of ultimately recoverable oil (URO) have remained relatively constant since 1965 at about 2 trillion barrels. Oil discoveries peaked in the 1950s and 1960s and have declined since. The world now consumes about three barrels of oil for each one discovered. An important factor that affects consideration of energy use is energy return on investment (EROI); the ...
