2. Biomass
• Biomass includes the use of food and wood.
Energy stored in non-fossil organic materials
such as wood, straw, vegetable oils and wastes
from the forest, agricultural and industrial
sectors. Biomass is one of the most important
renewable energy forms and its use in Canada
involves both the oldest and the newest of
energy technologies.
• Biomass is captured from forest industries. To
capture energy from biomass is to burn it, to
make heat, steam, and electricity.

4. Fossil Fuels
• Fossil Fuels include different types of oil, gas
and jet fuel. They are normally ‘natural
resources’ and are extracted from the earth
itself. Non-renewable resources. Fossil Fuels
may also be associated with mineral fuels. The
resources may be crushed, burnt, or turned into
steam.
• Fossil Fuels form from the organic remains of
prehistoric plants and animals.

6. Hydroelectric Energy
• Hydroelectric Energy produces energy through
power plants, some such as; Micro-scale,
small-scale and “run-of-the-river.” A dam is built
to trap water, usually in a valley where there is
an existing lake. Water is allowed to flow
through tunnels in the dam, to turn turbines and
thus drive generators. Notice that the dam is
much thicker at the bottom than at the top,
because the pressure of the water increases
with depth.
• Hydro-electric power stations can produce a
great deal of power very cheaply.

8. Nuclear Energy
• Nuclear Energy work by thermal nuclear reactors
and fast reactors. The thermal ones use a
moderator to slow down the neutrons produced
by fission. The moderator can be normal water,
heavy water, or graphite. The normal water
types are the Pressurized Water Reactor and
Boiling Water Reactor. Fast reactors don't have a
moderator, and therefore cannot be built with a
water filled core, so have used liquid metal,
usually sodium, as coolant.

10. Solar Energy
• Solar Energy, radiant light and heat from the sun, has
been harnessed by humans since ancient times using a
range of ever-evolving technologies. Solar powered
electrical generation relies on heat engines and
photovoltaic. Solar energy's uses are limited only by
human ingenuity.
A partial list of solar applications
includes space heating and cooling through solar
architecture, potable water via distillation and
disinfection, day lighting, solat hot water, solar cooking,
and high temperature process heat for industrial
purposes. To harvest the solar energy, the most
common way is to use solar panels.

12. Wind Energy
• Wind energy is energy obtained from moving air.
is the conversion of wind energy into a useful
form of energy. Some such as using wind
turbines to make electricity, wind mills for
mechanical power, wind pumps for pumping
water or drainage, or sails to propel ships.
• The motion results from the heating and cooling
of the Earth.
13.
14. Geothermal Energy
• Geothermal Energy is power extracted from heat
stored in the earth. Geothermal power is cost
effective, reliable, sustainable, and
environmentally friendly, but has historically
been limited to areas near tectonic plate
bouneries.
• This geothermal energy originates from the
original formation of the planet, from radioactive
decay of minerals, and from solar energy
absorbed at the surface.
