LEARNING OBJECTIVE

RENEWABLE RESOURCES•A renewable resource is a resource which is replaced naturally and can be used again. •Examples are: oxygen, fresh water, solar energy, timber, and biomass. Renewable resources may also include goods commodities such as wood, paper and leather.

BIOMASS•Biomass is a renewable source of fuel to produce energy because: waste residues will always exist – in terms of scrap wood, mill residuals and forest resources. •Biomass is fuel that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power. Some examples of materials that make up biomass fuels are: scrap lumber.

THE BATTERY LEVEL OF BIOMASS

•When the carbohydrates present in plants are burned, they turn back into carbon dioxide and water and release the energy they captured from the sun.• In this way, biomass functions as a sort of natural battery for storing solar energy. •As long as biomass is produced sustainably—meeting current needs without diminishing resources or the land’s capacity to re-grow biomass and recapture carbon—the battery will last indefinitely and provide sources of low-carbon energy.

NUCLEAR ENERGY•Nuclear energy is energy in the nucleus (core) of an atom. • The energy released during nuclear fission or fusion, especially when used to generate electricity. Nuclear power is derived from energy that is released when relatively large atoms are split in a series of controlled nuclear reactions. • The resulting heat is used to boil water which drives a steam turbine to generate electricity. • The process of splitting an atom is known as nuclear fission.

THE FATE REACTION OF NUCLEAR ENERGY•Nuclear reactions involve changes in an atom’s nucleus.Nuclear reactions result in the transmutation of one element into a different isotope or a different element altogether. • There are two types of nuclear reactions. • The first is the radioactive decay of bonds within the nucleus that emit radiation as it decays or transforms to a more stable state. • The second is the “billiard ball” type of reactions, where the nucleus or a nuclear particle (like a proton) is slammed into by another nucleus or nuclear particle.

GEOTHERMAL ENERGY•Geothermal energy is the heat from the Earth. It's clean and sustainable. •Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

HOT FORMATION OF GEOTHERMAL ENERGY•The steam rotates a turbine that activates a generator, which produces electricity. •Many power plants still use fossil fuels to boil water for steam. •Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.
