Since they are non-renewable, once they are gone, they are gone forever. It takes millions of years to create fossil fuels.  The graph shows the estimated amount of time three of the most popular fossil fuels have left before they run out if consumption continues at the rate it is at currently. Which strategy is most likely to help extend the life expectancy of our fossil fuels?

• Begin use more oil than coal for energy

• Develop technology that detects even the most minute amount of fossil fuels.

• Pass legislation to allow for more construction of gas stations along the interstates.

• Pass more legislation to contruct and utilize more renewable energy sources such as hydroelectric and wind power.
