Given line graph illustrates the relationship between the energy demand and the energy generated from fossil fuels in Fredonia over a period of two decades, from 1985 to 2005. The energy is expressed in units, each of which is equivalent to 100 billion megajoules.
The graph reveals that between 1985 and 1990, the energy demand dropped consistently from 5 units to 2 units. After that, it remained at the same level until 1995. Since then, the demand boomed dramatically from 2 units in 1995 to 7 units over a decade. Moreover, the demand is predicted to continue rising in the future.
On the contrary, the energy available from fossil fuels experienced a rapid increment in the starting 10 years. From approximately 3.5 units in 1985, it climbs up to nearly 6.5 units by the year 1995. From this point onwards, availability took a drastic downturn and remained constant at a level of about 2.5 units from the year 2000.
Overall, the graph represents that the energy demand followed an upward trend while, availability of energy from fossil fuels experienced a downfall over the period of 20 years.
