Alternative Sources of
Energy
By: JP Lester B. Delarmente
The Continuation
Hydropower
• Hydropower is electricity generated using the
energy of moving water. Rain or melted snow,
usually originating in hills and mountains,
create streams and rivers that eventually run
to the ocean.
• Ancient Greeks have used water wheels to
grind wheat into flour.

Hydropower
• First hydroelectric power plant was built at
Niagara Falls in 1879.
• Hydroelectric power provides almost one-fifth
of the world's electricity.
• Hydropower is the cheapest way to generate
electricity today.
Types of Hydropower
1. Impoundment - An impoundment facility,
typically a large hydropower system, uses a
dam to store river water in a reservoir. The
water may be released either to meet
changing electricity needs or to maintain a
constant reservoir level.
Types of Hydropower
2. Diversion - sometimes called run-of-river, facility
channels a portion of a river through a canal or
penstock. It may not require the use of a dam.
3. Pumped Storage - When the demand for
electricity is low, a pumped storage facility
stores energy by pumping water from a lower
reservoir to an upper reservoir. During periods
of high electrical demand, the water is released
back to the lower reservoir to generate
electricity.
Tidal Power
• It is a form of hydropower that converts
energy of the tides into electricity or
other useful forms of matter.
• Tidal energy is therefore an entirely
predictable form of renewable energy,
which can be harnessed in two forms:

Site/iStock_000003310838XSmall.jpg
Tidal Range
• It is the vertical difference in height between
the high tide and the succeeding low tide.
• Artificial tidal barrages or lagoons may be
constructed to capture the tide.

The Rance Tidal Power Station in
France.

math/wp-
content/uploads/2011/12/Barrage_de_la_Rance.jpg
Tidal Stream
• Tidal Stream is the flow of water as the tide
ebbs and floods, and manifests itself as tidal
current.
• Tidal Stream devices seek to extract energy
from this kinetic movement of water, much as
wind turbines extract energy from the
movement of air.
Image source: http://www.emerald-energy.co.uk/wp-
content/uploads/2012/03/Hydrodynamic.jpg
Wind power
• It is the process by which the wind is used to
generate electricity or mechanical power.
• Wind is the movement of air from an area of
high pressure to an area of low pressure.
• Farmers once used windmills to grind their
grains and pump water.
• Today, more and more people are using wind
turbines to wring electricity from the breeze.
Image source: http://conserve-energy-
future.com/Images/WindEnergy_Disadvantages.jpg
Wind powerWind power
• Wind energy production is growing rapidly
because construction of wind generators is
cheaper than building new fossil fuel-fired
power plants.
• Worldwide, wind is the fastest growing energy
source and many countries are rapidly
investing in new wind farms.
Kinds of Wind Turbines

Axis Wind
Turbines
Kinds Of Wind Turbines
1. Vertical Axis Wind Turbines – turbines look
like a giant egg beater to harness wind
energy.
2. Horizontal Axis Wind Turbines – turbines look
like giant propellers of a plane. It is the most
commonly used turbines.
Biomass Energy
• The term "biomass" refers to organic matter that
has stored energy through the process of
photosynthesis.
• It exists in one form as plants and may be
transferred through the food chain to animals'
bodies and their wastes, all of which can be
converted for everyday human use through
processes such as combustion, which releases the
carbon dioxide stored in the plant material.
Image source: http://wastetoenergysystems.com/wp-
content/uploads/2015/05/Biomass_Main.jpg
• Biomass has become one of the most
commonly used renewable sources of energy
in the last two decades, second only to
hydropower in the generation of electricity.
Biomass Energy
Advantages of Renewable Energy
1. Renewable energy is, well, renewable.
2. Environmental Benefits
3. Reliable energy resource
4. Economic benefits
5. Stabilize energy prices
Disadvantages of Renewable Energy
1. Reliability of Supply
2. Difficult to Generate in Large Quantity
3. Large Capital Cost
4. Large Tracts of Land is Required
Question
 What is the fastest growing energy
source in the 21st century?
Question
 What is the most abundant renewable
energy resource?
Question
 Where was the first hydroelectric
power built?
Summary: Renewables
 What is he purpose of having these
renewable energy resources?
 What do you think is the quickest and
the most effective way to decrease
energy consumption and to prolong
the availability of fossil fuels?

Editor's Notes

  1. In fact, wind exists because the sun unevenly heats the surface of the Earth.
  2. Renewable energy is, well, renewable: This means it has infinity of sustainability and we will never run out of it. Other sources of energy like coal, oil and gas are limited and will run out some day. Environmental Benefits: It is clean and results in little to no greenhouse and net carbon emissions. Reliable Energy Source: Our dependence on fossil fuels has increased considerably in last few decades. Economic Benefits: Renewable energy is also cheaper and more economically sound than other sources of generated energy. Stabilize Energy Prices: Switching to renewable energy sources also means steady pricing on energy.
  3. Reliability of Supply: One shortcoming is that renewable energy relies heavily upon the weather for sources of supply: rain, wind, and sunshine. In the event of weather that doesn’t produce these kinds of climate conditions renewable energy sources lack the capacity to make energy. Difficult to Generate in Large Quantity: Another disadvantage of renewable energy is that it is difficult to generate large amount of energy as those produced by coal powered plants. Large Capital Cost: Initial investments are quite high in case of building renewable energy plants. These plants require upfront investments to build, have high maintenance expenses and require careful planning and implementation. Large Tracts of Land Required: To meet up with the large quantities of electricity produced by fossil fuels, large amount of solar panels and wind farms need to be set up.
