Description: Fossil fuels – coal, oil and natural gas – are hydrocarbons which when burnt release energy.
Energy can be used directly e.g. petrol in cars or indirectly to produce electricity.

Advantages
Cheap and infrastructure for extraction is available.

Disadvantages burning of fossil fuels releases greenhouse gases which are linked to global warming.
Fossil fuels can be difficult and costly to extract, as they're buried deep underground.
Fossil fuels are non renewable - it takes about 1 million years to make the amount of fossil fuels we use in a year
Remaining fossil fuel supplies:
Coal – 250 years
Gas – 70 years
Oil – 50 years

Description: Wind energy is a form of solar energy. Wind energy is the process by which wind is used to generate electricity.
Wind turbines convert the kinetic energy in the wind into mechanical power. A generator then converts mechanical power into electricity.

Advantages:
wind is a clean, renewable energy source, and is one of the most cost-effective sources for electricity. It has low operating costs and it leads to a creation of jobs

Disadvantages:
Wind turbines can be noisy and unappealing aesthetically
Can  adversely impact the physical environment around them(blades can harm and kill species that fly into them)
Wind power is also intermittent(turbines are reliant on weather) and therefore aren’t capable of generating electricity 24/7.

Description: A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.

The generator converts the turbine’s mechanical energy into electricity.


Advantages: Completly renewable unless there is no water, emission free

disadvantages: there are droughts, its really expensive, has big environmental impact

description:
the heat produced from the planet's magma produces heat energy. but can only be accessed where the crust is thin, where tectonic plates meet and where volcanic activity is high.
they pump cold water into the cold ground and pressure build forcing the heated water which is now steam turning turbines creating electricity.

advantages:
Geothermal power stations emit 2000 times less carbon dioxide than fossil fuel power plants.
Sustainable / Stable
No Fuel Required
Rapid Evolution

disadvantages:
Gases are released into the atmosphere during digging.
Geothermal energy runs the risk of triggering earthquakes.

Most nuclear power comes from the fission of plutonium and uranium (at the moment).

Scientists speculate that if we could create a self-sustaining nuclear fusion energy reaction chain (like the sun) it would be could.

Advantages:
Provides electricity
Low operating cost 
Global climate compatible - few carbon emissions 
It can be used and created in different ways
It is a reliable source of energy

Disadvantages:
Initial investmest is expensive 
When exposed it can produce health issues 
Long term storage expenditures 
New power plants take a long time to construct

Advantage: Better for the environment as it's a cleaner energy source than the burning of fossil fuels, it won't pollute the air like power plants or produce atmospheric emissions such as acid rain, smog, or green house gases , and also won't run out (sustainable). Wind farms also creates jobs (manufacturing, installation, maintenance, and supporting services). 

Disadvantage: Need for land use (dominate the landscape), however, because of the need for a large plot of land, wind plants are in remote areas far away from the city where the electricity is needed. Therefore transmissions lines have to be built so that the electricity generated from the wind farms reaches the city. They also cause mild disturbance (wind turbines produce a lot of noise). Wind plants also effect wildlife, such as birds flying into the turbines and dying.

Unlike tidal energy which uses the ebb and flow of the tides, wave energy uses the vertical movement of the surface water that produce tidal waves.

Wave energy is actually a concentrated form of solar power generated by the action of the wind blowing across the surface of the oceans water which can then be used as a renewable source of energy. As the suns rays strike the Earth’s atmosphere, they warm it up. Differences in the temperature of the air masses around the globe causes the air to move from the hotter regions to the cooler regions, resulting in winds.


advantages
  • Wave energy is an abundant and renewable energy resource as the waves are generated by the wind.
  • Pollution free 
  • Reduces dependency on fossil fuels as wave energy consumes no fossil fuels during operation.
  • Wave energy is relatively consistent
  • Presents no barriers or difficulty to migrating fish and aquatic animals.
disadvantages

  • Visual impact of wave energy conversion devices on the shoreline and offshore floating buoys or platforms.
  • Wave energy conversion devices are location-dependent
  • Offshore wave energy devices can be a threat to navigation that cannot see or detect them by radar.
  • High power distribution costs to send the generated power from offshore devices to the land using long underwater cables.
  • They must be able to withstand forces of nature resulting in high capital, construction and maintenance costs.

Disadvantages
- Visual impact of wave energy conversion devices on the shoreline and offshore floating buoys or platforms
- Wave energy conversion devices are location dependent requiring suitable sites were the waves are consistently strong
- Intermittent power generation as the waves come in intervals and does not generate power during calm periods
- Offshore wave energy devices can be a threat to navigation that cannot see or detect them by radar
- High power distribution costs to send the generated power from offshore devices to the land using long underwater cables
- They must be able to withstand forces of nature resulting in high capital, construction and maintenance costs

Description: Hydroelectricity is a process of producing power through the use of streaming or falling water. It is not capable of emitting greenhouse gases. A dam is a large, man-made structure built to contain some body of water. Dams blocking the rivers lead to severe social and environmental impacts.

Advantages: Renewable; source of clean energy; stable and reliable; requires low operating cost; matches current demand.

Disadvantages: Causes environmental damage; cost of building is expensive; may cause droughts; floods in lower areas; shortage of water supply.
