It is clearly that petroleum and coal experienced fluctuated trends while natural gas experienced a increasing trend.

Started at 100 million tons, petroleum had the highest amount of oil produced, hit peak at about 130 million tons in 1983 then fluctuated until reached 120 million tons in 2000. In 1981, the amount of produced oil of coal less than petroleum 20 million tones, it has remained unchanged for 4 years then decreased to approximately one-third the amount of petroleum in 2000 and ranked the lowest.

In 1981, natural gas had the lowest amount, just two-fifth the amount of petroleum in 1981, it stayed the same until 1991 then significantly increased to almost 85 million tones in just 10 years and surpassed coal to rank the second highest amount which is almost doubled the amount of coal in 2000.

Overall, the most noticable is petroleum line with the highest starting and ending point. Another significant one is natural gas line with low begining point but rose sharply after years.

The petroleum line has highest starting point, which is 100 million tonnes, rise and fall over years and end at 120 million tonnes, it also reach peak twice at 140 million tonnes in 1983 and 1995. The natural gas one has the lowest starting point stay level for 14 years and increase significantly from 40 to over 80 million tonnes which is overly double the amount of oil.

The less given attention one is the coal line start at the nearly peak of the natural gas line and end badly at over 40 million tonnes

Overall, the production of Petroleum is the highest, while Coal shows a downward trend, compared to Natural gas.

The production of Petroleum started at 100(million tonnes of oil) is the highest among fuels. Additionally, During period from 1981 to 2000 shows an significant increased about 130 million tonnes of oil, expert period between 1989 and 1992 fall to under 100 million tonnes of oil.

Meanwhile, The production of Natural gas remain unchanged during 1982 to 1994 at 40 million tonnes of oil. In contrast, The Coal' Production started at 80 million tonnes of old, more higher as twice compare to Natural gas, Before witness a dramatical decreased after 1984 and continous fall down over time. While, Natural gas has experienced sharply rise at 80 million tonnes of oil, pass over Coal's production after 1995

Overall, it is apparent that the production of petroleum consistently took the lead, with coal and natural gas in the back.

In 1981, 100 million tonnes of petroleum was produced while coal was produced 20% less and natural gas at only half of coal production. 3 years later, the production level of petroleum rose to 130 million tonneds while the other two stayed stagnant. After a year, coal production lowered to around 45 million tonnes whilst the rest were stable. In the the next half a decade, natural gas production level didn't change as petroleum and coal production gradually decreased to 95 million tonnes and nearly 60 million tonnes respectively. In 1997, petroleum production had an upturn, going back to 130 million tonnes, whilst the other two types of fuels were equal at 50 million tonnes. At the start of the 21st century, petroleum production lowered slightly to 120 million tonnes, was natural gas production at approximately 80 million tonnes and coal production at half of that.

Overall, it can be seen that petroleum has the highest production level during this period, while coal declined considerably, and natural gas increased gradually and surpassed coal in the end.

Petroleum production started from 100 million tonnes, then rose significantly to approximately 130 million tonnes and remained stable from 1983 to 1987 before falling slightly to about 100 million tonnes. From 1993 to 1996, it grew back to 130 million tonnes and finally decreased back to 120 million tonnes. While petroleum fluctuated, coal experienced a downward trend as it fell considerably from 80 to 50 million tonnes between 1984 and 18985, then went up slightly before going down gradually by the end of the period.

Natural gas, on the other hand, experienced an upward trend, it remained stable at approximately 40 million tonnes from 1981 to 1991. After 1991, it rose gradually, surpassing coal in 1997, and by the end reached above 80 million tonnes in 2000.

Overall, petroleum witness the most significant number compared to natural gas, which goes through the upward trend like the previous one, and coal, which witness the opposite trend.

Petroleum started its line with the largest number, 100 millions tonnes of oil, and increased considerably to almost 130 before stayed stably for some time. Coal stay the same as 80 million before fell remarkably to nearly 50 million at the time that petroleum also started to went back to its original static. Meanwhile, coal climbed slightly to 60 millions before continuously fell down for the rest of the duration. After that big fall, petroleum rose largely to 130 then fell to 120.

On the contrary, natural gas took its first change, after years of staying 40 million, when petroleum witnessed the first decrease from 1981 to 2000. Natural gas then gradually rose to reach its peak for it to be over 80 million at the end of the duration, doubled the last static.

Starting from 1981 it's shown that petroleum is dominating the industry with a exceedingly staggering 100t, which continues to rose up rapidly up to 130t from 1982 to 1983, production reached a halt from 1983 onward to 1987, before going back to the initial digits in 1988 where then it continues on the downward slope stopping petroleum to it's lowest point at 85t in 1993. and within the same year proceeded to shoot up massively again, with some speed bumps along the way petroleum comes to it stop in the year 2000 with the final production level at 120t.

Moving to the other 2 charts being coal and natural gas with coal starting out with 80t while natural gas starts off at 40t respectively, both having a various venture in terms of productions over the years in the 20th century with 2 side having a complete opposite of each other in terms of progression, with coal getting a nosedive dropping down to 54t in 1985 with a small resurgence going upward in 1987 barely reaching 70t, only to completely plummeted again reaching it lowest and final amount of 39t in the 2000. As for the other side, natural gas started off steadily with zero movement remaining at 40t consistently, this trend ended with a small movement going up in 1991, which was then followed up by a unexpected skyrocket boosting non stop before hitting it highest and final production amount of 85t being reverse of coal where it completely dropped in the coming years.

Overalls, the charts serves as an valuable piece of knowledge, allowing us to get an idea of how unexpected changes can be within and world economy system, resulting in different sources of fuel getting a shift in either in it's benefits or disadvantage.

Overall, petroleum production went up and down a lot, but it was usually the highest. Coal production went down a lot. But natural gas production stayed the same at first, then it went up a lot at the end.

The production of the petroleum is the highest

Overall, although Petroleum has fluctuated, it was evident that it remained the highest fuel production source during the period. While natural gas production increased significantly this time, coal production steadily declined by 2000.

From 1985 to 1995, the figures of petroleum production fluctuated between approximately 100 and 130 million tons, and it continued to reach peaks. In contrast, the quantities of coal had no gradual fluctuation, and the production of natural gas had not changed

By 2000, coal had a trend to started at about 80 million tonnes and it steadily declined over the years, reaching approximately 50 million tonnes. While natural gas saw a significant increase, especially after 1995, it rose sharply from a low of 40 million tonnes to a high of 85 million tonnes. Meanwhile, the data suggests that changing energy priorities in the country, with a move towards cleaner fuels such as natural gas.

as we can be seen from the table, the highest fossil fuel in 1981 belong to potroloum which is highest 95 or 100 ton while coal is 80 ton higher than natural gas is 40 tons

in 1981, about 95 ton of petroleum were stay at hight if we comparing it to coal is 80 tons were procucted, pretroleum increased significantly reached at peak at 130 ton in 1983 and keep the same until 1987 and drop dramatically to the same as old is 95 tons in 1989, unlike petrolum, coal in 1981 is 80 ton and stay the same until suddenly to 50 ton in 1985 and slighly go up for 75 tons in 1987, in the 1992 both of petroleom and coal showed to fall lighly to 90 tons petroleom and 55 tons in coal, both of the fuels showed diffrently as in 1992 petroleum grow unstable before stop at 221 tons but coal is showed opposed it also fall unstable until stopped at 39 tons in 200

lastly is natural gas stay in the loswest in 40 tons unlike coal and petroloem it didn’t change before 1994 it sky rocket into 58 tons in 2000

Well petroluem reached at peak is 130 tons in 1983 stay in the highest, coal also drog significantly in 1985 in 45 tons, and natrual gas sudden;y sky rocket to 85 tons in 1994 and 200
