Transcript of Energy Resources and its types

Earth's
Energy Resources
In using all energy resources there are both
Advantages
and
Disadvantages
There are Two main types of resources we use to create energy
Non-Renewable
Resources
Renewable
Resources
Resources that are used to create energy,
But when they are used up, they are gone for good.
Examples
Coal
Fossil Fuels
Nuclear Power
and
Wil
willsd
Oil
Natural Gas
Coal
Most abundant fossil fuel -
The supply of coal will last to 50 years
BUT
Has to be mined out of the Earth, which causes HUGE problems for the environment and animal habitats!
Resources that are used to create energy,
But once they are used up they are gone for good!
Resources that cannot be used again -
Once the resource is used up, it is gone for good!
Also, when burned, releases heavy metals, carbon dioxide, and sulfur dioxide
Which pollutes the atomsphere!
Oil
A relatively inexpensive fuel source, and it burns cleaner than coal with less sulfur dioxide released...
BUT
Still pollutes greenhouse gases!
and
Its supply is estimated to last only about
30 more years!
Natural Gas
Cleanest fossil fuel!
NO sulfur dioxide is released.
Inexpensive to deliver to consumers -
once pipelines are in place
Supply is estimated to last 100 years or more!
Requires pipelines to be laid underground
which is an expensive process and not available everywhere...
and
natural gas is
Flammable
and
Odorless
can cause harmful
situations
Produced from Uranium -
which means no greenhouse gases!
But!
Dangerous if mishandled and there is NO system for disposing the hazardous waste left behind
There are alternatives to
Non-renewable resources

Sustainable resources that can be maintainedand when used, they can be replaced to use again
Examples
by: David Blaikie
Sun
Wind
Water
Organic Waste
Earth's Heat
Can use solar panels to create
Solar Power
Can use solar power toheat water in homes !
And power cars without putting polluting gases into the air!
by: mjmonty
These are considered to be cleaner
energy resources.
When using these natural resources,
we can have a negative impact on
ecosystems and possibily the economy.
And these resources are not avaiable everywhere where energy is needed - you cannot ship these resources to other places like you can with non-renewable sources
by: mjmonty
The fastest growing energy technology:
Wind Power
By: Kevin Dooley
Wind turbines are used to generate electricity as strong winds turn the turbine blades.
Although there is no pollution admitted like that from vehicles on the road...
Strong winds are not in enough places to supply all the electricity needs we have and A wind farm can have a negative effect on wildlife
Water sources like rivers and lakes can be used to generate electricity constantly through
Hydropower
by: Michael Fludkov
A very clean and basically free energy source,
once the dam or plant is build.
More RELIABLE than
wind or solar power!
however
Also dams disturb fish and animal life!
People like to use waterways for recreation -
and People want to settle on the water...
So sites to produce Hydroelectricity are limited!
Organic materials are being turned into energy!
which is referred to as -
Biomass
For Example
Corn stalks can be converted into biofuels
Which can be used to provide heat
or power a car!
by: Joel Penner
However
Growing or collecting enough fuel to
meet energy usages can be difficult.
Biofuel is BURNED = Greenhouse Gases like with fossil fuels
Not to mention -
Plus

We can take the heat
from underground
most likely in volcanic areas
and turn it into
Geothermal Energy
When the water is mixed with molten rock
it sends hot steam up to the surface
Water is injected into hot spots in the Earth and steam comes up that is used to generate power!
NO Pollution is created!
Not much impact on
Environment!
Some places may run out of steam for years and years
OR
hazardous gases could come up with the steam!

by: Allie Caufield
To put less stress on our planet, we must think of how we can use our
We need to begin using less coal and more natural gas
While also continuing to explore how areas can rely on more than one renewable resource and even alternateresources according to seasons or weather patterns
Research indicates that the best way to improve our environment is to use less energy and put less greenhouse gasses into the atmosphere. If we could conserve energy more often then our natural, renewable resources could be used with less impact on the environment.
Not many places are sutiable for geothermal plants because of the lack of necessary hot rock below the surface and rock on the surface that is easy to drill into.
A greater demand for orgainic waste means more water used to grow crops, more fertilizer that runs off into water supplies, and the higer some grown food costs will increase!
This allows for less dependence on limited supply of fossil fuels
AND
Is cheaper to produce.

What are the Advantages of Nuclear Energy?
• Nuclear reactions release a million times more energy, as compared to hydro or wind energy. Hence, a large amount of electricity can be generated. Presently, 12-18% of the world's electricity is generated through nuclear energy.
• The biggest advantage of nuclear energy is that there is no release of greenhouse gases (carbon dioxide, methane, ozone, chlorofluorocarbon) during nuclear reaction
• Nuclear reactors make use of uranium as fuel. Fission reaction of a small amount of uranium generates large amount of energy, are expected to last for another 100 years.
• High amount of energy can be generated from a single nuclear power plant. Also, nuclear fuel is inexpensive and easier to transport.

a
Coal
Advantages
Coal can be found in lots of places in the world and there is still plenty in the UK.
Coal can be easily transported to the power stations.
Coal is a relatively cheap energy source

Advantages

Coal can be found in lots of places in the world.
Coal can be easily transported to the power stations.
Coal is a relatively cheap energy source
Advantages
Oil and natural gas are found in lots of places in the world.
We can transport oil and gas in pipes and by using tankers or ships

Disadvantages
Environmental damage can be caused when building the rig and by accidental oil spillages.
Oil and gas are not renewable, so once the supplies are used, they will run out.
Burning these fuels releases greenhouse gases into the air. This may add to global warming.
The price of oil and gas will increase because supplies are running out and lots of people will want it
Working on an oil or gas rig can be dangerous due to the risk of explosions and bad weather

Advantages
Nuclear fuel does not make harmful greenhouse gases.
You only need a very small amount of nuclear fuel to make a lot of energy
Disdvantages
The waste that is produced when using nuclear fuel is radioactive and very harmful. It needs to be disposed of carefully
Nuclear power stations are at risk from terrorist attack and sabotage.
World uranium supplies may run out in about 50 years
Advantages
The energy from the Sun is free.
The sun does not produce greenhouse gases.
The sun will always be there during our lifetime
Disadvantages of Solar Energy
The initial cost is quite high.
Most types of solar cells require large areas of land to achieve average efficiency.
Air pollution and weather can also have a large effect on the efficiency of the cells.
The silicon used in cells is also very expensive.
Currently, solar energy costs about twice as much as traditional sources i.e. coal, oil etc.
Advantages

When the electricity is generated, no greenhouse gases are made.
The water used is free.
It is a renewable energy source
