Hi! My name is Laura Diaz. I’m a fifth grade student. I was born on March
25th of 2,000. I live in Cali and I am 12 years. I like to watch TV, eat pizza,
chat with my friends, and be with my family, I have 2 older brothers, and in
this IV part of my virtual booklet I’m going to show you what are energy
resources. This booklet is a project but I think that is very important that
everyone can know about energy resources so we can protect it. In this
booklet you will know everything of Energy Resources, types, definition of
the types (what is), etc…
I hope you like it!!!
WELCOME!!!
Energy
resources do
not produce
energy in any of
their forms.
Non-renewable energy
cannot be replaced,
that means that once
we use it we cannot use
it again.
Renewable energy
are the ones that
we can use it
without diminishing
the resource.
Do you
know what is
energy in
social studies
term?
I don’t
remember… Do
you remember if
energy is to
cook?
Energy resources
are not used for
energy
production, in
any of their form.
RENEWABLE ENERGY:
Renewable energy sources, also known as natural sources of energy, are those which it
is possible to use without diminishing the resource.
Hydropower
Hydropower is one of most established true renewable energy source. This is the
utilization of the potential energy caused by a height different in two levels of
electricity.
Biomass
Biomass power is where organic materials are utilized to generate power. This is
probably the oldest renewable energy
Wind Power
Wind power depends on utilizing the wind to generate electricity or carry out some
other activity (such as pumping water). As with many other renewable energy sources
it has a history going back quite centuries.
Tidal
Tidal energy is a natural source of energy which utilizes the power of the tides. Tides are
caused by the gravitational pull of the moon, and to a lesser extent the sun upon the
earth's oceans. The tidal motions follow a cyclical pattern, and so unlike other forms of
renewable energy such as wind and waves it is possible to predict with great accuracy
the power output of a tidal energy device well in advance of it being placed within
the water, which is a great bonus.
Geothermal
Geothermal are renewable energy sources which utilize the heat within the earth to
create either a source of renewable heat or renewable electricity.
Solar electric
Solar electric relies on the power of the sun to generate renewable electricity through
a variety of mediums. There are a series of ways of converting a solar energy resource
into renewable electricity including photovoltaics (PV), solar chimneys and
concentrated solar power. http://bristolboy.hubpages.com/hub/Renewable-Energy-Natural-Sources-of-Energy
NON-RENEWABLE ENERGY:
Non-renewable energy sources cannot be replaced in our lifetime, or that of our children or
even our childrens’ children. Once these energy sources have been used up that’s it, they
are gone forever.
PETROLEUM
Petroleum is extracted and turned into a variety of fuel sources including petrol or gasoline,
diesel, propane, jet fuel, heating oil and paraffin wax. Also known as crude oil, this fuel
source is nonrenewable. Petroleum is made when organic matter settles in water that has
lost its dissolved oxygen and is then compressed under immense heat and pressure for
millions of years.
COAL
Coal is also composed of organic matter --- matter that decomposed in peat bogs, which
then formed into carbon rock under immense pressure. Coal is generally highly combustible
and the world's most-used resource for electrical generation. However, burning coal releases
massive amounts of carbon dioxide into the atmosphere, which is the primary factor in the
greenhouse effect. In addition to being greenhouse gas source, coal cannot be
reproduced.
NATURAL GAS
Also a byproduct of decomposition, natural gas is mostly methane created as organic
matter decays. Once extracted, natural gas is processed to remove everything but the
methane, it is a nonrenewable energy source because it is a byproduct of thousands of
years of decomposition within the earth's crust.
NUCLEAR POWER
Nuclear energy may get mentioned in the same breath with renewable power sources like
wind and solar because it is clean-burning and therefore more environmentally sound than
oil or coal. But nuclear energy is, in fact, a nonrenewable resource. The problem lies in the
element that enables nuclear power: uranium. The element uranium is abundant, but only a
certain type of uranium, U-235, is used to fuel nuclear power. U-235 must be extracted from
mined and processed uranium. The processing produces only small amounts of U-235,
making it rare and expensive. Man cannot reproduce this element; we have a limited
natural supply.

Definition:
Eolic energy is wind energy. The definition of wind energy is: energy obtained from
turbine engines powered by wind.
EXAMPLES IN COLOMBIA:
- Colombia has only a wind turbines generating capacity of 20 MW in a wind farm of
the company Jepirachi EPM.
- As of 2010, the only wind farm operating in Colombia is located in La Guajira
province, a region in the north-east of the country. This onshore wind farm has fifteen
units of 1.3 MW each for a total nominal power of 19.5 MW. This farm, the first one built
in Colombia, was commissioned in 2004 and it is connected to the national grid by a
110 kV transmission line.
- According to the report, the wind regime in Colombia has been ranked among the
best in South America. Coastal regions of the northern part of the country have been
classified as class seven winds (winds over nine meters per second (m / s) at a height
of 50 meters).
- Colombia only has an installed capacity of 19.5 MW of wind energy (Jepirachi wind
farm with 15 wind turbines inaugurated in 2003 and built with World Bank support), with
some other wind farms projects under consideration, including a wind farm Ipapure
200 MW.

Definition:
Hydroelectric energy is a renewable energy source using the hydrologic cycle of
water, which involves evaporation and the flow of water due to gravity.
Accessing this energy from flowing waters can produce low-cost electricity. Today, this
is the largest form of renewable energy in the world.
Hydroelectric Plants in Colombia http://www.industcards.com/hydro-colombia.htm

Energy needs to be conserved to protect our environment from drastic changes, to
save the depleting resources for our future generations. The rate at which the
energy is being produced and consumed can damage our world in many ways. In
other words, it helps us to save the environment. We can reduce those impacts by
consuming less energy. The cost of energy is rising every year. It is important for us to
realize how energy is useful to us and how can we avoid it getting wasted.
To start saving energy is not a big thing at all. We can start saving the energy from
our home itself, just by turning off the lights during day hours, washing clothes in
cold water or using public transport instead of using our own vehicle and later can
implement these things on much wider scale at society level, then at city level then
district level and finally at country level. You might notice a small change in your
monthly bills by implementing these changes as they would be getting decreased
more and more. With so many alternatives and so many techniques about there, if
millions of people like us start doing these things, it will help us to save much more
money and also help the environment.
