1. TYPE OF ENERGY:
Coal
Coal
Coal is the number 1 global energy polluter.
Coal accounts for 50% of US electricity generation.
Except South America, all continents have substantial coal
reserves.
In 2006, coal supplied 25% the world's energy.

3. How does it create
energy?
Coal is burned in power plants.
The process to generate energy from coal involves mining the
coal, then transporting, cleaning and burning it.
Water heated by burning coal converts into steam and
generates electricity.
Each stage of this process generates pollution.

5. Alternative Method
Coal could create energy through coal gasification which is a process
which converts solid coal into a gas that an be used for power
generation.
This method is more environmentally friendly as it removes sulphur
and other contaminants.

7. What % of the world's
energy comes from coal?
In 2006, coal supplied one quarter of the world's energy.
Although this proportion has fallen steadily over the past 20
years, world production actually increased by over 60%
between 1986 and 2006.
Coal production increased everywhere except Europe with
Asia (including China) recording the fastest growth.

9. What country uses
coal the most?
China.

10. Where is coal found?
Coal is found underground.
The biggest supply of coal is found in the USA.

11. Pros
Produces a lot of energy when burned
The U.S. contains one-quarter of the world's coal
reserves, which could provide more energy potential
than all the known recoverable reserves of oil.
Provides jobs for Americans.

12. Cons
Less transportable than oil and gas because...
It contains a larger proportion of waste
It has lower calorific value than oil and gas
It is a solid and less transportable by than liquids and gases
It is less versatile than oil, having little value for the transport industry

14. Oil
by Ella & Gin

15. How does oil create
energy?
Oil is a form of stored energy which is released
during combustion
It comes from plant matter which is
decomposed to form hydrocarbons which burns
as fuel

16. What percentage of the worlds
energy comes from oil?
In America, 16.5% of their
energy comes from oil
In Africa 12.1% comes
from oil
The Middle East is 13.1%
More than half of Eurasias
oil comes from Russia
47% of the worlds energy
is from oil.

17. Where is oil found?
In the Middle East oil is the most accessible
Canada, Iraq, Iran, Venezuela, US, Russia,
Libya
Oil is found in pores that are buried deep
beneath the earths surface, between layers of
hard rock

19. Pros for using Oil
No other energy source can move
vehicles with greater speed at
longer distances than oil.
It creates jobs for the local
economy
It can be used in cars
It can be converted into electricity
It can be used in plastics and wax

20. Cons for using oil
Oil is nonrenewable and so it will run out
Burning oil pollutes the environment by releasing CO2 and other toxic
gasses
Big oil rigs are needed to extract oil
Oil leak may occur which result in environmental disaster like killing
wild live, disturbing the biodiversity of that area and this takes years to
clean up
It is expensive and dangerous to transport it
Drilling for oil is unpredictable and takes a lot of time to search for oil

24. HOW DOES IT CREATE ENERGY?
Counts for 13% of world primary energy
production
80% of this energy came from combustible
renewables (mainly wood for heating)
17% came from hydropower
Altogether wind,tide, geothermal and solar
energies contribution to total world energy
production Is just 0.5%

25. Geothermal energy
The natural heat found in the earths crust in the
form of steam, hot water and hot rock. This source
of energy can be used to produce electricity or its
hot water bath can be used directly for industry,
agriculture etc.
eg. In Iceland hot springs supply water at 86 deg c
to 95% of the buildings in and around Reyhjavik
The number of countries producing power from this
source could rise from 21 in 2000 to 46 in 2010
The USA is the world leader in geothermal
electricity and accounts for 0.37% of electricity
used in the US

26. Where is IT found?
Share of renewables by
religion (total primary energy
supply)
Africa holds the largest share of 49%
Wind energy has an annual growth rate 48%
Renewable energies rely on the elements to produce electricity therefore
Hot countries are best suited to provide solar energy
Mountainous religions such as the Andes can provide HEP
Islands can obtain great stores of tidal energy and wind energy

27. Positive impactS
Renewable therefore less damage to the environment
Will never run out
Does not aggravate global warming
Reduce fossil feel dependency
Decreases necessity for nuclear waste
Reduces the need for importing from east (therefore improves
trade balance)
Unlimited (infinite) quantities

28. Negative impacts
Rich countries in n America and Europe have a
disproportionate share of the new renewables eg.
Cahora Bassa dam
Limited by high capital costs
Need for sophisticated technologies
Visual pollution
Conservationists worry about wind turbines affects on
migrating birds
HEP dams can damage fishing industries and delicate
ecosystems

The UK generate about 1% of it's

This figure is low because most

However, in July 2005, Scottish
ministers approved plans to

station in Inverness. The new
plant will generate up to
100megawatts of electricity.

It is a reliable source of energy
in areas where it is suitable to
