2. THE GOAL IS FOR STUDENTS TO
UNDERSTAND THE FOLLOWING OUTCOMES:
• Classifications of Energy sources
• Understand basic terminology for renewable
energy
• Gain a core level knowledge of different forms of
renewable energy
3. WHAT IS POWER
GENERATION?
Electricity generation is the process of
generating electric power from sources
of primary energy. For utilities in the
electric power industry, it is the stage
prior to its delivery to end users or its
storage. Electricity is not freely available
in nature, so it must be "produced".
4. Energy can be classified into several
types based on the following criteria:
• Primary and Secondary energy
• Commercial and Non-commercial energy
• Renewable and Non-Renewable energy
• Conventional and Non-conventional energy
10. • Thermal solar panels are
used to generate heat energy,
• Photovoltaic (PV) cells made
from silicon turn sunlight
directly into electricity
ENERGY
17. • Geothermal energy = heat energy from
the Earth
• Decay of radioactive elements and
residual heat from planetary formation
4.5 billion years ago
• Water is pumped down into hot rock
where it is heated.
• Steam can then be used to heat buildings
directly or to generate electricity by
spinning a turbine.
ENERGY
24. FOSSIL FUELS (COAL, OIL AND NATURAL GAS)
• Thermal power station which
burns a fossil fuel, such as coal
or natural gas, to produce
electricity
• Fossil fuel power stations have
machinery to convert the heat
energy of combustion into
mechanical energy, which then
operates an electrical generator
25.
26.
27. NUCLEAR POWER
• Nuclear power plants are a type of
power plant that use the process of
nuclear fission in order to generate
electricity.
• They do this by using nuclear
reactors in combination with the
Rankine cycle, where the heat
generated by the reactor converts
water into steam, which spins a
turbine and a generator.
Editor's Notes
Require source of energy to be converted to electricity.
Primary energy consists of unconverted or original fuels. Secondary energy includes resources that have been converted or stored.
Primary energy sources include petroleum, natural gas, coal, biomass, flowing water, wind, and solar radiation. Those are the fuels that can be mined, reaped, extracted, harvested, or harnessed directly.
Secondary energy cannot be harnessed directly from nature; rather, secondary energy is energy that has already been converted.
Commercial Energy- The energy sources that are available in the market for a definite price are known as commercial energy.
Non- Commercial Energy - The energy sources that are not available in the commercial market for a price are classified as non-commercial energy. Also known as traditional fuels.
Renewable energy is energy obtained from sources that are essentially inexhaustible. The most important feature of renewable energy is that it can be harnessed without the release of harmful pollutants.
Non-renewable energy is the conventional fossil fuels such as coal, oil and gas, which are likely to deplete with time.
Solar power is generated directly from sunlight (photons). Solar thermal panels are filled with water which heats up in the sunlight. The heated water is then pumped through a tank heating the water that is connected to the taps in the house.
Solar photovoltaic (PV) cells use the suns energy to convert are made from two layers of silicon crystal. When photons hit the top layer of silicon they ‘excite’ the negatively charged electrons in the silicon atoms giving them enough energy to move towards the positively charged lower layer, inducing an electrical current.
A solar charge controller is used to keep the battery from overcharging by regulating the voltage and current coming from the solar panel to the battery. It is used to prevent batteries from being damaged by overcharging and over-discharging by controlling the current flow from and to the batteries. They can also protect the appliances that are connected to the batteries.
A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC).

Wind turbines are built to harness wind energy (kinetic energy). When the wind blows the blades move and spin a turbine connected to a generator which produces electricity. Wind turbines essentially work in the opposite way to a fan, instead of using electricity to make wind, they use wind to make electricity.
In order to create enough energy capable of powering thousands of homes, energy companies build large wind farms with lots of wind turbines. Wind turbines need to be built in the direction of prevailing winds and ideally on a clear hill top.
Wind Power Plant- the rotor is connected to the main shaft, which spins a generator to create electricity.
Rotor Blade- to absorb the kinetic power of the wind.
Gear Box- dito nakalagay yung mechanical system and set of gears
Generator- wind turbine generator converts mechanical energy to electrical energy
Power Cables -transmission of electrical power
Switchyard - Switchyard controls the exchange of electrical energy. It monitors the electrical parameters in each transmission line like the voltage, current .
Geothermal energy is heat energy from the Earth generated by the decay of radioactive elements and residual heat from the Earth’s formation 4.5 billion years ago. Hot springs have been used since Palaeolithic times for bathing and the Romans harnessed geothermal energy for underfloor heating and to heat their public baths, however nowadays geothermal energy is better known for electricity generation.
To use geothermal energy water is pumped down into hot rocks through pipes where is it heated. When this water and steam comes back up to the surface it can be used directly to heat people’s homes, buildings, greenhouses etc., or the steam can be used to generate electricity through spinning turbine connected to a generator.
Geothermal energy can only be harnessed where the rocks are hot enough. This is generally around plate boundaries like in Iceland, New Zealand and Italy, where heated rocks tend to be much closer to the surface. However, recent technological improvements have increased the geographical range of geothermal power. In the UK, granite beneath Cornwall has been targeted as a potential source for geothermal power.
Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity.

Hydroelectric power harnesses kinetic energy from running water. Hydroelectric dams are built to store large amounts of water in reservoirs made from flooding river valleys. When electricity is needed, water is let out through pipes in the dam. The water flows downwards under the influence of gravity and turns turbines linked to generators to generate electricity.
Hydroelectric power is more reliable than wind and solar power, although hydroelectric dams are expensive and depend on finding a suitable valley site to build and flood. This in turn effects the people and animals living there as well as impacting on the migration patterns of fish.
Magat Dam is a large rock-fill dam in the island of Luzon in the Philippines. The dam is located along the Magat River, a major tributary of Cagayan River. The construction of the dam started in 1975 and was completed in 1982. It is one of the largest dams in the Philippines. It is a multi-purpose dam which is used primarily for irrigating about 85,000 hectares (210,000 acres) of agricultural lands,[1] flood control, and power generation through the Magat Hydroelectric Power Plant.
the fact is it remains one of the major renewable sources of energy available to the world. The energy is created through a specific nuclear reaction, which is then collected and used to power generators. While almost every country has nuclear generators, there are moratoriums on their use or construction as scientists try to resolve safety and disposal issues for waste.
Nuclear energy is produced from uranium, a non-renewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity. Scientists think uranium was created billions of years ago when stars formed. Uranium is found throughout the earth’s crust, but most of it is too difficult or too expensive to mine and process into fuel for nuclear power plants. In effect, as they operate, they will ‘renew’ their own fuel resource.
The possible outcome is that the resource of fuel available for fast neutron reactors is so abundant that significant depletion of the fuel source is almost impossible under practical terms
