# In the 1950s, the United States produced about the same amount of energy that it consumed. However, since then, a gap has grown between consumption and production. Today, the United States produces less energy than it consumes, and the difference is met by imported energy, mostly petroleum. Consider the following graph: a. Estimate the increase in energy consumption (in quads) between 1949 and 2012. What is the average yearly increase during this period? b. Estimate the increase in energy production (in quads) between 1949 and 2012. What is the average yearly increase during this period? c. What is the gap (in quads) between production and consumption in 2012?

## In the 1950s, the United States produced about the same amount of energy that it consumed. However, since then, a gap has grown between consumption and production. Today, the United States produces less energy than it consumes, and the difference is met by imported energy, mostly petroleum. Consider the following graph:a.

Estimate the increase in energy production (in quads) between 1949 and 2012. What is the average yearly increase during this period?c. What is the gap (in quads) between production and consumption in 2012?

Interpretation Introduction

Interpretation:

Increase in energy consumption between 1949 and 2012 is to be estimated and the average yearly increase during this period is to determined. The increase in energy production between 1949 and 2012 is to be estimated and the average yearly increase during this period is to be determined. The gap between the production and the consumption in 2012 are to be calculated.

Concept Introduction:

Energy is the property that is required by an object to perform work and to heat itself and it can be measured.

The average change is calculated by dividing the change in the value by the elapsed time.

### Explanation of Solution

a) The increase in the energy consumption between 1949 and 2012 and the average yearly increase during this period.

The average energy consumption between 1949 and 2012 is calculated as follows:

Theyearlyaverageconsumption=Energyconsumptionin2012Energyconsumptionin194920121949

Substitute the value of energy consumption in 1949 and 2012 in the above expression.

Hence, the average yearly energy consumption between 1949 and 2012 is,

b) The increase in energy production between 1949 and 2012 and average yearly increase during this period.

The average energy production between 1949 and 2012 is calculated as follows:
