Energy Consumption

The graph shows consumption of main energy resources in the USA since 1980 until 2030. There are two main features. 

The accompanying graph shows consumption of principal energy resources in the USA from 1980 to 2030.

(“Main” is ok. The synonym principal would work well here.)

The consumption of underground sources such as petrol, coal and natural gas increased steadily in long period. In 2005, natural gas consumption peaked and it is predicted it will not be increased until 2030 

The consumption of underground resources such as petroleum, coal and natural gas has increased steadily over the long term. However, the rate of natural gas consumption peaked in 2005 and it is predicted that it will not peak again until 2030.

On the other hand, there are no significant changes about renewable and alternative energy consumption. For instance, solar energy using was 3 quadrillion units in 1980 and it did not increase well. In conclusion, this graph illustrates the hunger of underground source consumption of the USA. USA did not try to produce energy with alternative and renewable way of doing it and it is expected that it will not happen. The underground sources is going to take more role on energy using.

On the other hand, renewable and alternative energy consumption rates have not changed significantly. For instance, in 1980 the consumption of solar energy was 3 quadrillion units and to date this rate has remained almost the same.

The comparisons visible in the graph indicate a hunger for underground resources. There have not been great efforts towards producing more energy from renewable resources in the USA and this trend is not changing. We can conclude that underground resources will continue to be exploited at an ever increasing rate.

( I was able to understand your essay. Good work! The changes I suggest here are mainly for clarity.)
