Do fossil fuels insulate the crust from the Earth's interior?

Quoting from John Russell's response to this article, "This is arrant nonsense!" Russell concludes with How did this paper get through the peer-review and editorial review processes? What ...

What is the most important source of natural gas? Coal, oil or other?

The most important source of natural gas is natural gas. This is why it is called natural. It is not "made" from oil or coal. Natural gas forms by decomposition of organic material. Whether the ...

Do fossil fuels insulate the crust from the Earth's interior?

What neither the authors nor the response by John Russell takes into account is that all underground oil and gas is stored inside tiny pores of rocks. An oil reservoir is not a big underground cave, ...

Are fossil fuels really formed from fossils?

Let's look at this. A very large number of points for one question. First, the solar system. We do not see any hydrocarbons in the inner solar system (Mercury to Mars). This is because in this region ...

Why is helium only found in wells mixed with natural gas?

Helium is produced by the radioactive decay of primordial uranium and thorium. It should not be strongly associated with non-primordial 'fossil' hydrocarbons. The first statement is correct. The ...

Diamonds are expensive. Really expensive. Even "cheap" synthetic diamonds are orders of magnitude more expensive than conventional fossil fuel. By using them as fuel, you will increase ...

Why is the creation of water from the combustion of hydrocarbons not listed as a cause for rising sea levels?

1.2 x 10^13 kg equals 12,000,000,000,000 l water. One liter equals 0.001 m³, while one km³ equals one billion (1 x 10^9) m³. So we're supposedly adding 12 km³ water to the atmosphere per year. ...

Are there probably decent oil fields located in the middle of the ocean?

Are there probably decent oil fields located in the middle of the ocean? tl;dr: no. Hydrocarbon deposits form by thermal maturation (i.e. slow and mild heating) of buried organic matter (i.e. dead ...

Are there gases from the Earth useful to generate electricity besides "natural gas"?

The category "other gases" may not solely include other naturally occurring gases extracted from the Earth. As you state natural gas is predominantly methane, extracted from the Earth. Another type ...

Petroleum and coal formation

Coal, oil and gas can be found anywhere on Earth: on land and on sea. The Japanese once mined coal from beneath the sea floor, using Hashima Island as the base of operations. The island is only 6.3 ...

Does the amount of energy released from burning of fossil fuels have a measurable impact on global warming?

Yes, it does add to global warming. No, it's not currently measurable. Human primary non-renewable energy consumption is about 15TW - and pretty much all of that goes into low-grade heat in the ...

Scarcity is the biggest limit, diamonds burn much like coal but unlike coal they are extremely rare. artificial diamonds would still cost vastly more to make than digging up coal.
