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
