Some questions about fossil fuels, three common fossil fuels

In 2008, 1 kilogram of standard coal in China could generate kilowatt-hours (kWh) of electricity, and one ton of standard coal could generate 2,780 kWh. Now the mining cost of one ton of coal is about 120 yuan.

The proportion of gas that is made into coal gas is about 10% or 15%.

Are you talking about the fact that there are fossils and there are living individuals at the same time? What is this called a living fossil? They all have fossil finds.

"Living fossils" are lines in phylogeny that have not undergone advance evolution for a long time, nor have they undergone branching evolution. In addition, there is no interruption of the lineage (extinction), but the result of a state of stagnant evolution. and must remain a living species.

With the same habitat and very low seed growth rate, these organisms have not changed for millions of years. As a result, some ancient organisms that have lasted for tens of millions of years have been formed, and other creatures of the same era have long been extinct, and only they have survived alone, living in a very small area, called "living fossils".

In 1938, the first remaining remnants of the total finned fish speartail were discovered in the waters of southeast Africa, and it is one of the world's most famous living fossils. China's current gymnosperms ginkgo, water pine and mammal giant panda are all recognized as precious living fossils by the world.

Of course, there are their fossils. You only need to search for "panda fossils" or something like that. See for yourself. Since they can be called living fossils, it means that there are both fossils and living individuals

The mining cost is about 120 yuan.

The proportion of gas that is made into coal gas is about 10% or 15%.

Three common fossil fuels: coal, oil, and natural gas (blended, all non-renewable energy).

Fossil energy is a type of hydrocarbon.

or derivatives thereof. It is deposited from fossils of ancient organisms and is a primary energy source.

Fossil fuels emit toxic gases when they are not completely burned, but they are essential fuels for human beings.

Natural gas refers to all gases that occur naturally in nature, including the atmosphere.

Gases formed by various natural processes in the hydrosphere and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coal seam trace gas, and biogenerated gas in Pina, etc.); Petroleum is a viscous, dark brown liquid known as the "blood of industry."

Fossil fuels refer to coal, oil, natural gas, and other non-renewable fuel resources that are buried in the ground and under the ocean. Fossil fuels are classified into coal, oil, oil shale, natural gas, oil sands, and combustible ice under the sea in order of the amount of energy buried.

Fossil fuels, also known as ore fuels, are a mixture of hydrocarbons or derivatives of hydrocarbons, including natural resources such as coal, oil and natural gas. Fossil fuels are non-renewable resources formed by a series of complex changes in the remains of ancient organisms.

The use of fossil fuels can enable large-scale industrial development and replace water wheels. When electricity is generated, energy is generated during the burning of fossil fuels, which propels turbines to generate power. Old-style generators used steam to propel turbines.

Nowadays, many power stations already use gas turbine engines, which use direct gas leakage to propel turbines.

A fossil fuel is a hydrocarbon or a mixture of hydrocarbon derivatives, including natural resources such as coal, oil, and natural gas. Fossil fuels are non-renewable resources formed from the remains of ancient organisms through a complex series of changes. The use of fossil fuels can enable large-scale industrial development and replace water wheels.

When electricity is generated, energy is generated during the burning of fossil fuels, which slides and propels turbines to generate power. Old-style generators used steam to propel turbines. Many power stations now use gas turbine engines, which use gas to propel turbines directly.

Fossil fuels, also known as ore fuels, are hydrocarbons or their derivatives, which refer to coal, oil, natural gas, and other non-renewable fuel resources buried in the ground and under the ocean.

Fossil fuels are divided into coal, oil, oil shale, natural gas, oil sands, and combustible ice under the sea in order of the amount of buried energy. Fossil fuel coal is formed by the action of underground and geothermal heat of plants buried in the ground, after tens of millions or even hundreds of millions of years of carbonization process, the release of water, carbon dioxide, methane and other gases, the oxygen content is reduced, and the amount of carbon leakage is very rich. Due to the different geological conditions and the degree of evolution, the carbon content is different, and thus the calorific value is also different.

According to the order of calorific value, it is divided into anthracite, bituminous coal and lignite. Coal is widely distributed on the earth and is not concentrated in a certain origin. Petroleum is a hydrocarbon formed by the debris of microorganisms that accumulate in water, under the action of high pressure.

Natural gas is extracted directly underground and contains methane.

1.Greenhouse gas emissions: Burning fossil fuels releases large amounts of carbon dioxide and other greenhouse gases, which are one of the main greenhouse gases and have a negative impact on climate change.

2.Air pollution: Burning fossil fuels emits large amounts of particulate matter, oxides, and other air pollutants that negatively affect air quality and lead to respiratory problems and other health problems.

3.Energy security: Reliance on fossil fuels can create energy security concerns. Since most fossil repatriation fuels are finite resources, there are instability and geopolitical risks. In addition, volatility and competition pose challenges to energy security.

4.Environmental damage: The process of extracting and extracting fossil fuels can cause damage to the environment, including deforestation, land destruction, and biodiversity loss. Offshore oil and gas extraction can lead to pollution of the marine environment.

6.Non-renewable: Fossil fuels are finite resources, and their use will lead to resource depletion. In addition, the costs and technical challenges of extracting and extracting fossil fuels are increasing.

In the face of these shortcomings, society is actively promoting the development of renewable energy and the energy transition to reduce dependence on fossil fuels, reduce environmental and climate impacts, and find more sustainable and clean energy alternatives. <>
