Energy Assignment Part 1

You are going to start this assignment by researching 3 of the following types of energy production options. Please research ones that interest you AND NOT just the ones that your friends choose. I will be checking when I mark to ensure that natural social groupings have no researched the exact same things. 
For EACH of the energy types that you research you should look at the pros and cons, how we use it, the benefits, drawbacks etc. Make sure that you are familiar with how they work. 

From the following list choose THREE: 
-Coal
-Nuclear
-Solar
-Tidal
-Wind
-Hydrothermal
-Geothermal

Coal:

Coal is a fossil fuel which is used around the world to produce electricity. It is a black sedimentary rock. Somethings it can be brown is very flammable. It is mostly made out of organic carbon and is a primary source for energy. It is mainly used to produce heat or electricity. Back in the days it was frequently used to heat up homes and power factories and trains. Since the 2000's coal consumption as risen up a lot than any other fuel globally. Around 6 billion tonnes of coal were used world wide in 2014! Thats how important coal is in modern society.

Pros for coal:
-inexpensive
-supply is more in industrialized cities/countries
-good utilization
-cheaper than gas (better to invest in financially)
-continuous power
-can change to a liquid state
-can turn into low carbon 

Cons for coal:
-not a renewable source
-has a large contribution to global warming
-has different levels for radiation
-emits methane (a lot of it)
-bad for environment around it
-has carbon dioxide in it
-impacts human health negatively
-burning coal emits mercury
-increases the rate of asthma and cancer in lungs

Solar:

Solar energy comes from the suns rays which is converted into electricity for various products. For instance light bulbs to light up a  house! This type of energy can be used in heating pools, water, homes and even for ventilation. It can heat up things that coal can heat up! Many people use solar energy lights on their driveway. So how does it work? There are panels called solar cells that convert sunlight into electricity. Using the energy of photons it creates current with the panel. A photon is created in the sun by the fusion of atoms.

Pros:
-Can replace certain products that need coal
-Using it is cost efficient
-Renewable source
-High efficiency
-Doesn't pollute the atmosphere
-saleable of at least 100MW level

Cons:
-low energy
-a little more expensive than the solar PV
-have to set it up in a proper location
-need to have proper upgraded technology to create
-to create the panel is super expensive
-Needs a lot of space
-does not look pretty in backyards
-manufacturing may cause pollution
-people still would rather buy gas (its cheaper)

Wind:

This type of energy also can be used for almost anything.. It can power boats, batteries and be used for electricity! In the olden days instead of wind turbines there was wind mills. Wind turbines convert energy in the wind and change it into mechanical power. This power can be used for pumping water or giving light in a house. Wind turbines can use generators to turn the wind energy into electricity. Which leads the house having light.

Pros of wind energy:
-also renewable
-a sustainable option
-no land is being drilled to collect it (saves environment)
-power is free
-cost is lower
-can be used almost anywhere

Cons of wind energy:
-have to rely on government as wind power may not be cheap
-turbines make a lot of noise
-birds have casualties from the propellers
-wind is not always blowing in the sky
-wind is inconsistent and unpredictable
