问答题

The demand for energy dropped steadily between 1985 and 1990 from 5 units of energy to approximately 2 units. From 1990 until about 1995, energy demand appeared to level off and remained constant at about 2 units of energy. From this time onwards, energy demand climbs dramatically from 2 units of energy in 1996 and is projected to reach 7 units in the year 2005. Furthermore, the forecast is for energy demand to continue to rise in the future.In contrast, the amount of energy available from fossil fuels increased quite rapidly from about 3.5 unit sice 1985 until it reached a peak of 6.5 in 1995. From this point onwards it is projected to decline dramatic-ally until it remains constant at an availability level of around 2.5 units from the year 2000.The energy demand and energy available from fossil fuels resulted in an excess amount of energy available in the 1990s in Freedonia which, perhaps, was due to the availability of alternative sources of energy. On the other hand, an energy gap that continues to widen is forecast, beginning in the late 1990s. In the future, Freedonians will have to enforce energy saving measures or look towards the use of alternative sources of energy.
