Problema Solution
In 2008, world natural gas proven reserves totaled 6185 trillion cubic feet, while annual consumption was 105.5 trillion cubic feet in 2006. The USGS projected then that world consumption would increase 2.2% per year through 2025.
What was the static reserve for natural gas in 2008?
Answer provided by our tutors
Let P = 105.5 trillion cubic feet
r = 2.2 = 0.022
t = 2
P(t)= 105.5(1+0.022)2
P(t)= 110.193 trillion cubic feet
Total gas in 2008 = 6185 trillion
Static reserve = 6185-110.193 = 6074.81 trillion cubic feet
