  2. Kerosene - Wikipedia

    en.wikipedia.org/wiki/Kerosene

    Kerosene was also produced during the same period from oil shale and bitumen by heating the rock to extract the oil, which was then distilled. [21] During the Chinese Ming Dynasty , the Chinese made use of kerosene through extracting and purifying petroleum and then converted it into lamp fuel. [ 22 ]

  3. Abiogenic petroleum origin - Wikipedia

    en.wikipedia.org/wiki/Abiogenic_petroleum_origin

    The Gravberg-1 well only produced 84 barrels (13.4 m 3) of oil, which later was shown to derive from organic additives, lubricants and mud used in the drilling process. [32] [33] [34] Kudryavtsev's Rule has been explained for oil and gas (not coal)—gas deposits which are below oil deposits can be created from that oil or its source rocks ...

  4. Vegetable oils as alternative energy - Wikipedia

    en.wikipedia.org/wiki/Vegetable_oils_as...

    There is a limited amount of fossil fuel inside the Earth. Since the current world energy resources and consumption is mainly fossil fuels, society is very dependent on them for both transportation and electric power generation. The Hubbert peak theory predicts that oil depletion will result in oil production dropping off in the not too distant ...

  5. Hubbert peak theory - Wikipedia

    en.wikipedia.org/wiki/Hubbert_peak_theory

    "Hubbert's peak" can refer to the peaking of production in a particular area, which has now been observed for many fields and regions. Hubbert's peak was thought to have been achieved in the United States contiguous 48 states (that is, excluding Alaska and Hawaii) in the early 1970s. Oil production peaked at 10.2 million barrels (1.62 × 10 ^ 6 m 3) per day in 1970 and then dec

  6. Life-cycle greenhouse gas emissions of energy sources

    en.wikipedia.org/wiki/Life-cycle_greenhouse_gas...

    The scale uses the global warming potential unit, the carbon dioxide equivalent (CO 2 e), and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from material and fuel mining through construction to operation and waste management.

  7. Environmental impact of electricity generation - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    Geothermal energy is the heat of the Earth, which can be tapped into to produce electricity in power plants. Warm water produced from geothermal sources can be used for industry, agriculture, bathing and cleansing. Where underground steam sources can be tapped, the steam is used to run a steam turbine.

  8. Kerogen - Wikipedia

    en.wikipedia.org/wiki/Kerogen

    All the kerogen on earth is estimated to contain 10 16 tons of carbon. This makes it the most abundant source of organic compounds on earth, exceeding the total organic content of living matter 10,000-fold. [1] The type of kerogen present in a particular rock formation depends on the type of organic material that was originally present.

  9. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    A fossil fuel [a] is a carbon compound- or hydrocarbon-containing material [2] formed naturally in the Earth's crust from the buried remains of prehistoric organisms (animals, plants or planktons), a process that occurs within geological formations.
