My Q is abt de renewable n non-renewable sources of energy!!!?

Question

The fossil fuels we r gettin now is known to all that they r non-renewable sources of energy, but how's that! i mean, these fuels r obtained by decomposition of the dead organisms of pre-historic ages, but what happened to the organisms that died after those times? Won't they form fossil fuels? That means, even these fuels r renewable sources since the organisms which dies now might get converted to fuel later!!! plz some one xplain this if i'm wrong!!!

Answer 1

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

This kind of large scale conversion is NOT taking place now; therefor it is a non renewable source of energy.

Answer 2

I wish you were right. However, as others have partially explained, you are not because there was a period of time when the conditions were just right that the growth of plants was so rampant that the dieing residue was produced in such huge quantities (compared to now) that the raw materials were available to begin the natural processes that produced out fossil fuels (oil and coal). That is not the case today (and was only the case for a comparatively short time in geological terms) and cannot be the case unless carbon dioxide levels are increased to levels that will not sustain animals that breath our atmosphere. The plants then had so much CO2 that they could grow luxuriantly compared to now. They sucked up that carbon dioxide for photosynthesis and produced more oxygen that changed our atmosphere so our ancestors could breath. Now, we are putting that CO2 back into our atmosphere by combusting these fuels. Theoretically this may cause global warning (some contend this is happening already) due to the build up of CO2 and other byproducts of combustion. This could again even make the atmosphere very animal unfriendly but likely will never reach that extreme.

Answer 3

The fastest way to answer this is that "natural production of fossil fuels" hasn't been constant over the millions of years. The Carboniferous Period, about 300 million years ago, had an unusually high density of plant life and vast swamps, which eventually produced most of the fossil fuels that we find buried deep underground today. Sure, more fossil fuels are being produced right now, but nowhere at the rate it once was.

Answer 4

Water by far. Sunlight is good only for clear days, and for only 6-8 hrs at the most. Plus it is too expensive to buy the solar panels for electricity. Under glass tubing is less expensive but still too short a day light time source. Wind is cheaper mechanically, and probably more hours of production overall. But still depends on sufficient air movement. Water from river flow is the most constant 24/7 production. Dams, are expensive but are multipurpose. Electricity, irrigation, drinking, recreation, flood control. Paddle wheels anchored along rivers or streams also produce continuous electricity and are cheap. They can be smaller or larger. Ocean waves and tides are being looked at as a continuous source also. All water sources of renewable energy are by far and away the most efficient. Water is heavy at 8+ lbs per gal. it does not take very much flow on a lever arm to multiply its effect dramatically.

Answer 5

Technically, yes. But we are using up these resources at such a fast rate, that it will be a couple million years before more oil or coal is formed (IF they are, as these are both formed from swampy conditions, most swamps are drained today)
