  2. Vegetable oils as alternative energy - Wikipedia

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

    Plants use sunlight and photosynthesis to take carbon dioxide (CO 2) out of the Earth's atmosphere to make vegetable oil. The same CO 2 is then put back after it is burned in an engine. Thus vegetable oil does not increase the CO 2 in the atmosphere, and does not directly contribute to the problem of greenhouse gas.

    Popular choices for plant biofuels include: oil palm, soybean, castor oil, sunflower oil, safflower oil, corn ethanol, and sugar cane ethanol. A 2008 Hawaiian oil palm plantation projection stated: "algae could yield from 5,000-10,000 gallons of oil per acre yearly, compared to 250-350 gallons for jatropha and 600-800 gallons for palm oil ".

  4. Vegetable oil - Wikipedia

    en.wikipedia.org/wiki/Vegetable_oil

    Some vegetable oil blends are used in unmodified vehicles but straight vegetable oil, also known as pure plant oil, needs specially prepared vehicles which have a method of heating the oil to reduce its viscosity. The use of vegetable oils as alternative energy is growing [citation needed] and the availability of biodiesel around the world is ...

  5. Biofuel - Wikipedia

    en.wikipedia.org/wiki/Biofuel

    Algae and cyanobacteria will use water, carbon dioxide, and solar energy to produce biofuels. [89] This method of biofuel production is still at the research level. The biofuels that are secreted by the bioengineered organisms are expected to have higher photon-to-fuel conversion efficiency, compared to older generations of biofuels. [89]

  6. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Some shade-loving plants (sciophytes) produce such low levels of oxygen during photosynthesis that they use all of it themselves instead of releasing it to the atmosphere. [ 12 ] Although there are some differences between oxygenic photosynthesis in plants, algae, and cyanobacteria, the overall process is quite similar in these organisms.

  7. World energy supply and consumption - Wikipedia

    In comparison, the refined forms of energy include for example refined oil that becomes fuel and electricity. Energy resources may be used in various different ways, depending on the specific resource (e.g. coal), and intended end use (industrial, residential, etc.). Energy production and consumption play a significant role in the global economy.

  8. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    The other major use for fossil fuels is in generating electricity and as feedstock for the petrochemical industry. Tar, a leftover of petroleum extraction, is used in the construction of roads. The energy for the Green Revolution was provided by fossil fuels in the form of fertilizers (natural gas), pesticides (oil), and hydrocarbon-fueled ...

  9. Types of plant oils - Wikipedia

    en.wikipedia.org/wiki/Types_of_plant_oils

    There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.
