Title: Energy around the world- does one size fit all?
1Energy around the world-does one size fit all?
2What types of energy are available around the
world?
3Biomass
- Biomass is an organic material made from plants
and animals. Biomass can be wood, manure, and
even some garbage! - Biomass energy is created by burning biomass
material. The gases that are released are made
into electricity, and the steam it releases can
directly heat houses. - Some biomass, like garbage, releases methane gas,
which is the main ingredient in natural gas.
Since natural gas is a non-renewable resource, we
can substitute a renewable resource, like
biomass, into a very similar renewable resource.
That is better for the environment. - Biomass can pollute the air when it is burned,
though not as much as fossil fuels can.

4Nuclear
- Nuclear energy supplies 16 of the worlds
energy. - It is created by using a nuclear reactor, and
uranium particles are either split or combined to
create energy. Nuclear fission is used more than
nuclear fusion. - Pros- Nuclear energy could produce energy even
after fuel and coal run out. Nuclear plants need
less fuel than fossil fuel plants- one ton of
uranium produces energy that would take several
million tons of fossil fuels. Well operated
nuclear plants do not pollute. - Cons-They produce radiation, which is very
harmful to humans if they are exposed. Nuclear
explosions can happen if a meltdown occurs-
nuclear reactions happen too quickly and too
often. The Chernobyl disaster was caused by this
happening. If nuclear wastes are not stored
correctly they can result in explosions, just
like if they were in use.

5Hydrogen
- Hydrogen is the most plentiful gas in the
universe. It is a simple element, and it only
exists as a solid compound when combined with
other elements on Earth. - To make hydrogen into a form of energy, we must
first separate it from the other bonds in the
compound it is in. Next it is turned into a gas
by steam reforming or electrolysis. Then it is
ready to be turned into energy! Hydrogen is
usually turned into a fuel cell, although it can
be used once it is in its pure hydrogen gas
state. - Every region in the world has some type of
material that can be used to process hydrogen,
and this makes this type of energy very
accessible. - Hydrogen can power everything from cars to homes
to laptop computers. It is also a very clean
source of energy and does not emit any type of
fume or vapor.

Theres even a hydrogen powered cell phone!

6Wind
- In this form of energy, wind turns the
turbine. The blades turn a shaft inside the
nacelle (the box at the top). The shaft goes into
the gear box which increases the rotation speed
enough for the generator to convert rotational
energy into electric energy using magnetic
fields. - Pros- Wind is free, and wind farms dont need to
use any fuel! Wind energy produces no waste or
greenhouse gases, and the land beneath the
turbines can still be used. - Cons- On some days there is no wind, so a backup
energy source is needed. Although it is extremely
rare, birds can be killed by the turbines.
Sometimes the turbines are noisy, but that too is
rare.

7Hydroelectric
- Hydropower is one of the most used forms of
energy in the US today. - Hydroelectricity is made from deriving mechanical
energy from flowing water. This is often
accomplished by building a dam to collect water.
The amount of available energy from water is
determined by its flow and fall. Water that runs
very fast or falls a great distance is the most
suitable for use as hydropower energy. - When the water is inside the dam, it turns a
wheel, called a penstock, which in turn produces
electricity in a generator on the shore. - Hydropower is a great form of energy because it
costs almost no money. There are no waste
by-products, and it does not pollute the water or
the air.

8coal
- Pros- It is inexpensive and if in great supply,
very reliable. It provides about half of the
United States' energy. - Cons- The burning of coal is one of the least
environmentally friendly energy sources, leaving
its large mark on planet Earth. It is
nonrenewable, so when it is gone, it is gone for
good, and can take several hundred million years
to form again. Burning coal produces more carbon
dioxide than burning oil or natural gas, and the
fumes contribute to acid rain.

9Oceanic
- There are many types of oceanic energy. They
are - Tidal
- Wave
- Water/Solar
- Water/Wind
-
- These types of energy are useful because they
use water, which is plentiful, to harvest
electricity in a non-impact way.
10Oceanic-Continued
- Tidal- Like wind energy, tidal energy is produced
with the use of a turbine. In the tidal system,
there are many turbines placed parallel to each
other. All of the water that passes the turbines
is forced through them, and this spins a wheel
which in turn generates electricity. Tidal
turbines are clean and can be used anywhere with
a tide range above 10 feet, but they are
expensive and may harm plant and animal life. - Wave- Waves are huge sources of energy. We can
use this energy by bending the waves into a
channel, increasing their size, and then using
the water to spin turbines to generate
electricity. This form of energy could be used
anywhere large waves break near the shore and
would be useful for the West Coasts of the US and
Europe and in New Zealand and Japan.

11Oceanic-Continued
- Water/Solar Energy- Since the ocean makes up 70
of the surface of Earth, why not put a solar farm
on the top of the ocean? Solar panels would be
placed just offshore to collect solar energy.
Then the panels would transmit energy to the land
to be used. - Water/Wind Energy- This type of energy can be
used everywhere along the coast of the US. It is
just like a continental wind farm, where wind
turbines are placed to change wind into energy.
Some people oppose this because it would change
the view of the ocean.

12Natural gas
- Pros- Natural gas is efficient, economical, and
reliable. Remember how your gas stove worked when
the power went out? - Cons- It is less environmentally friendly than
other alternatives, but friendlier than oil and
coal energy. Because it is nonrenewable, when it
is gone, it is gone. This could make demand much
higher in the future, making the price skyrocket.

13solar
- Solar energy is an excellent and environmentally
friendly energy source for areas of the world
that receive large amounts of sunlight. - It can be used to heat water and spaces.
- Solar energy is generated using two types of
panels- photovoltaic cells, which are the kind
you see on houses and are not connected to a
power grid, and cells connected to power plants. - Pros- It is environmentally friendly, very
accessible and useful in sunny areas. Renewable - Cons- Solar panels are expensive to install and
maintain, which limits the amount of countries
that could benefit from it. Solar panels can only
work when it is sunny, so it can be used in
limited areas where sunshine is great enough for
the solar cells to be profitable.

14geothermal
- Geothermal energy is derived from the same force
that builds mountains, erupts volcanoes, and is
responsible for hot springs. - Geothermal energy is sourced from geothermal
reservoirs, which can be found in few areas.
California could benefit from geothermal energy
because of their fault lines, where geothermal
reservoirs are normally found. - Pros- Environmentally friendly- they produce no
smoke, only steam, and they are cost efficient.
Renewable. - Cons- Only available in select places.

15oil
- The US produces only 40 of the total amount of
oil it uses. - The top oil producing countries are Saudi
Arabia, Russia, and the United States. - Pros- Low cost, compact generators, easy to store
and transport. - Cons- Oil is nonrenewable and being used at a
fast rate, it is a source of conflict trading
wise, and when in transport, oil can spill
causing great environmental strain.

16Where can these types of energy be found and why
are they useful?
17Biomass
- Accessible all over the world
- 70-90 percent of people in Africa use wood, a
biomass material, to heat their homes - 50-60 percent of all developing countries in Asia
use biomass - Clean
- Cost-effective, and anyone can have their own
biomass
18Nuclear
- Virtually can be used in any part of the world
- Limited to countries that can afford it
- Cost in excess of 13 billion
- Japan, Russia, the United States, Korea, and
China have all harnessed nuclear energy - Sometimes nuclear energy is not used to benefit,
like in WWII
19Hydrogen
- Abundantly located in every region of the world.
- Very clean form of energy
- Likely to be used in countries with a substantial
amount of money, because the whole process is
somewhat expensive - US, China, Japan, India, and other countries may
be the pioneering forces in making this energy
available to everyone.
20Wind
- Can be used in places with wind speeds of over 10
mph. - Can withstand 140 mph winds
- Mostly found around the coast or in desert or
plain areas - Wind energy is cost effective, but installation
is expensive - Most always found in rural areas, would take up
too much space in the city
21Hydroelectric
- Best used in mountainous areas with rivers, or
areas with rivers in general - Many places in Africa, the Middle Sast, Siberia,
and Asia may not be able to access this form of
energy - Europe, Canada, South America, the USA and other
areas of the world are well suited for
hydroelectricity
22Coal
- Can be harnessed where it is found or imported.
- People are choosing more environmentally friendly
alternatives. - Remains the cheapest, and supplies many American
and world wide households
23Oceanic
- Useful to countries and states located on the
ocean or any other large body of water - Wave and tidal energy are the only exceptions to
that rule, because they require substantial
amounts of change in sea level and waves must
break close to the shore to generate a high
amount of electricity - These forms of energy would be helpful to poorer
countries, because they are all relatively
inexpensive
24Natural Gas
- Can be used where it is found or imported.
- Like coal, it is cost effective.
- India, the United States, Canada, and Russia all
use natural gas in great amounts.
25Solar
- Very smart energy choice in sunny parts of the
world countries on the equator, India, Alaska,
Arizona, or Hawaii etc. - Island nations could benefit from solar energy.
- Panels can be expensive if put on a large area,
so some countries, or cities could not use them
26Geothermal
- Can only be used in a small part of the world
where geothermal reservoirs are found. - Includes countries surrounding the Ring of
Fire, the Philippines, Alaska and California. - Has also been used in Europe.
27Oil
- Can be used anywhere in the world.
- Creates a significant amount of pollution,
countries or states with large amounts of
pollution might use a more environmentally
friendly alternative. - Oil is one of the best choices for poor
countries.
