Advantages and disadvantages

non renewable

renewable

coal

Fuel Wood

Wind

Solar

tidal

HEP

Nuclear

Biofuel

Solar power can be used to generate electricity

heat water

reduce energy expenditure required

cannot be created during the night

Oil

reduced during times of cloud cover

Natural Gas

solar panels can be a substantial initial investment

free energy for use

wind power is not always generated

areas in which wind is not very strong, or very frequent, may not benefit from the construction of wind power facilities.

They can be very noisy

in heavily populated areas, a very large amount of wind turbines may be necessary

clean energy source on the basis of greenhouse gas emission

disadvantages

Advantages

do not create any disturbance to their surrounding environment

increments global warming

it is not a renewable source

Harms the environment

they only take up a small plot of land at their base

Remote areas that are not connected to the electricity power grid can use wind power to create their own supply of electricity

Hydroelectricity does not "use" water, all of the water is returned to its source of origin

pollutes and releases greenhouse gases

can be created 24/7 and is a clean source of energy

The power plants, once in place, do not create any waste byproducts in their conversion

we over consume it too fast

coal is easy to burn

coal produces energy with combustion

coal is inexpensive

coal is abundant

coal is a reliable energy source

power plants, hydroelectric plants are very expensive to build

The high cost means that plants must operate for a long time to become profitable

The creation of dams can also create flooding of land

natural envrionment and the natural habitat of animals, and even people, may be destroyed.

cause a lot of water access problems

nuclear energy can be a very useful and powerful source of easing dependence on fossil fuels

disadvantages

Advantages

its easy to produce

oil can be produced all day and night while wind and sun are not always constant

oil has a high energy density

Oil spills are a huge risk, they pollute the earth and the water, this oil spills are more common than what we think and they affect the animals and plants a lot

people fight for getting the best spot to drill oil so this generates tension between governments and people.

greenhouse gas is released so it increments global warming and acid rain chances

nuclear power plants safer than ever

Nuclear power plants also produce no greenhouse gas emissions after they are up and running

he running costs of nuclear plants are also very low due to the fact that a very small amount of uranium produces a very large amount of energy.

Nuclear energy reduces the dependence on foreign oil and natural gas

nuclear powerplant undergoing a meltdown would act as a nuclear bomb and destroy everything with a hundred miles

the land many miles surrounding the plant would be uninhabitable for several decades.

nuclear power does produce some greenhouse gases. Nuclear power plants are also very expensive to build.

always happens

easy to obtain

Biofuels are a renewable energy source in that they are created from plants that can be regrown each year.

Biofuels also do not require many changes

biofuels can help reduce the dependence on foreign oils, which fluctuate in price rapidly

the machniery required to farm the plants for biofuels does create carbon emissions

setting aside land for biofuel crops means less land for food production

biofuels help to reduce carbon emissions by 50-60%.

Advantages

Disadvantages

Does not contaminate as much as Coal and Oil

The least expensive fossil fuel

safer than other fossil fuels

Safer to store than the other fossil fuels

Besides it is the less embironment damaging fossil fuel it still releases some greenhouse gases

Generates violence and terrorism

It is a non-renewable source of energy

it is difficult to detect as it is smell less and colour less

It is highly combustible
