I've included three links. The three main fossil fuels are oil, natural gas and coal. If you examine the graphs in the related links, you will see since about 1960 to the present, the trendline is significantly higher, so we are in the time period of high growth (year over year increases) in the use of fossil fuels worldwide. The increase in petroleum use has contributed to carbon dioxide emissions as shown in the related links. You can see that the growth in emissions has accelerated in the last three decades. This is related to more use of cars and population growth worldwide. Coal usage has also trended higher. However, the increase in coal started over 50 to 100 years ago. People may have a different opinion as to which decade there was a significant change in the trend- was it 1950, 1960 or 1970? But from all information to date, the same upward trend continues until now.

At what time was fossil fuels considered renewable?
Fossil fuels were never a renewable resource.
How long does it take for the earth to make fossil fuels in years at a time?
It takes millions of years for fossil fuels to be naturally formed.
Fuels that can only be used once?
It can never be true that fossil fuels can be used only once because fossil fuels can be made again but if it has been buried it will take a longer time
What are the leading theories for the formation of fossil fuels?
The generally accepted theory for the formation of fossil fuels is that vegetable matter, dating back to the Carboniferous Period, became buried underground, and over time, with compression and heat in the absence of oxygen, it was transformed into the various fossil fuels, coal, petroleum, and natural gas. There is also one other theory which has some plausibility, which is that fossil fuels are much older than the Carboniferous Period, and are derived from the Earth's atmosphere, before the first appearance of green plants that produce oxygen. At a sufficiently early period in Earth's history, hydrocarbons may have been extremely abundant, just as they are in the outer solar system.
Today's fossil fuels began forming about 300 million years ago in pennsylvanian period. what was most likely true about that time period?
Many huge plants grew, decayed and died.
At what time was fossil fuels considered renewable?
Fossil fuels were never a renewable resource.
Is time a fossil fuel?
No, time is not a fossil fuel. Fossil fuels are coal, oil and natural gas.
Which of the following is not a renewable energy source solar energy wind energy geothermal energy fossil fuels?
Fossil Fuels. The sun, wind and heat from the earth core is continuously being produced. Fossil Fuels were created over a long period of time and required a lot of heat and pressure to be created which is why they are not considered to be renewable.
What causes decrease in fossil fuels?
Time
Why fossil fuels are called non-renewable source of energy?
Fossil fuels took millions of years to form. The time scale is such that it is not possible to renew fossil fuels on a human time scale. It is for that reason that they are called non-renewable.
Has the use of fossil fuels changed over time?
it will change if we use lots of fossil fuels. Because we cannot make fossil feuls because it is from long time ago. from:Alex
How might actions contribute to global warming?
Any time we use electricity produced from fossil fuels, and any time we use fossil fuels (transport).
How long does it take for the earth to make fossil fuels in years at a time?
It takes millions of years for fossil fuels to be naturally formed.
Why are these resources referred to as fossil fuels?
"Fossil fuels" refers to fuels, such as carbon and petroleum, that are generally believed to originate as fossils.
Were fossil fuels formed from minerals under the earth's crust?
Fossil fuels are produced by the decomposition of animal and vegetable matter over time
What is an advantage of fossil fuels?
The advantage of fossil fuel is it is cheep to make and the implement to use it is also cheep to make also. If you think about how much it would cost to make other types of fuels and the device to make power from those fuels fossil fuel is the cheapest.
What country does fossil fuels come from?
The sun. Fossil fuels are made up of plants and animals that lived in the past and have been converted to fossil fuels by geological processes over time. And as plants convert the suns energy into sugars, fossil fuels are stored solar energy.-----------------------------------------------------------------------------------------------The energy comes from the energy that was previously in dead plants/animals... to understand better read about the carboniferous period. It explains how fossil fuels were created, through the compression of decaying plant material that had lots of locked up carbon underneath layers of sediments.
