Q:

How do biofuels work?

A:

Quick Answer

Biofuels are plant-based fuels made from organic matter and can be used in conjunction with traditional fuels (such as fossil fuels) to create more sustainable energy sources. Current biofuels fall into three main categories: ethanol, biodiesel and other biomass.

Full Answer

  • Ethanol is a biofuel derived from alcohol found in corn and cane sugar. It is most often mixed with gasoline and is used to power automobiles.
  • Biodiesel is made from vegetable oil and other natural oils. It can be used interchangeably with regular diesel (it does not need to be mixed) and allows automobiles and other diesel-powered machines to run more cleanly and release less toxic waste.
  • Other biomass includes all other forms of alternative, plant-based energy used to provide electricity or transportation. This includes burning wood chips for energy, collecting methane from manure piles and other innovations that transfer energy from natural materials into electricity or fuel.

  • Q:

    What form of energy is stored in fossil fuels?

    A:

    Fossil fuels store sunlight, which derives from plants using energy from the sun for photosynthesis. This light energy remains dormant in fossil fuels and dates back many years. Fossil fuels release this energy upon activation, such as burning.

    What are natural resources found in the tundra?

    A:

    Natural resources in the tundra include plants, animals, such as caribou, elk and foxes and sources of energy including uranium and oil. Natural resources refer to usable items deriving from nature, instead of undergoing an artificial manufacturing process in human hands. These resources range from living beings, such as berries, mushrooms and whales, to nonrenewable sources of fuel and economy-stimulating products like metals and minerals.

  • Q:

    What are different types of energy sources?

    A:

    Non-renewable and renewable energy sources are the two types of energy. As the names state, non-renewable sources such as fossil fuels are not able to be used again. Renewable sources such as wind can be used over and over again.
