4. •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.

6. • 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.

8. 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.

9. 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.

11. 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.

12. 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.

14. 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.
