We get energy from gas by burning it and using the exhaust to turn our turbine. The heat is also used to boil water which in turn goes through another turbine; these turbines then turn electrical generators. The energy transfer in this is going from chemical potential to kinetic and heat to just kinetic to electricity.
Natural gas is one of the big three fossil fuels that the world runs on. Recently our wold has turned to natural gas as a larger source of our energy as it produces less less pollutants than coal or petroleum.

Pros of Natural Gas

1. Produces Less Soot:  Natural gas is always pointed towards when it comes to producing less pollution than other fossil fuels in its production as its byproducts are in gaseous form. It burns cleaner than gasoline or diesel. It releases 45% less carbon dioxide than coal and 30% less than oil and has therefore less impact on the environment.

2. Abundant Supply: It is abundant and available worldwide. There are over a trillion barrels of natural gas reserves in the US alone that have not been harvested. Just like oil and coal, natural gas is a finite source that has to be conserved to be a viable power source. In the coming years, many sites are waiting to be discovered.

3. Infrastructure in Place: The technology to produce natural gas already exists as the same is used to harness fossil fuels. The familiarity with the current technology makes it easier for us to harness natural gas in the same way. It is used extensively for power generation and heat.

4. Cheaper: Natural gas vehicles are far more energy efficient, as are other engines powered by it – which makes them cheaper to run. Given that most of the engines in the world of all types are gas based, the cost of converting or replacing them is prohibitive. It is most common used fuel in homes for heating and cooking purposes.

5. Transportation: Natural gas can be easily transported via ships, tankers and pipes. It is lighter and easier to transport in terms of carbon footprint. This makes natural gas a viable option to be used in residential homes. One of the main benefit of natural gas is that it is used to make plastics, chemicals, fertilizers and hydrogen.

Cons of Natural Gas

1. Highly flammable: Natural gas is a highly flammable substance that can cause significantly more damage should there be an accident. Natural gas leaks can cause fires or explosions, if not handled carefully. It is colorless, tasteless and odorless and cannot be detected by smell unless an odorant is added to it.

2. Greenhouse Gas Emissions: When natural gas is burnt, it releases carbon-dioxide, monoxide, and other carbon compounds in the atmosphere. These gases transfer carbon from the earth to the atmosphere, thus contributing towards greenhouse effect.

3. Non-Sustainable: Natural gas is non-renewable and will eventually expire one day like other fossil fuels. It is not a sustainable form of energy and is not an answer to ever growing energy crisis problem that this world is facing. The need is to look beyond that and invest heavily is renewable form of technologies.

5. Expensive Pipelines: The infrastructure needed to use natural gas is very expensive as long pipes, specialized tanks, and separate plumbing systems need to be used. Long distance transmission and transportation requires extra cost. Fixing of leaking pipes add to the running cost.

The tide moves a huge amount of water twice each day, and using it could provide a great deal of energy - around 20% of Britain's needs.

There are eight main sites around Britain where tidal power stations could usefully be built, including the Severn, Dee, Solway and Humber

Nuclear Fission is essentially splitting a nucleus. Usually uranium or Plutonium are used as they have large nuclei that are easy to split open when hit by neutrons. When a nucleus is hit by an atom:
-the nucleus splits into two smaller nucleui, which are radioactive
-two or more neutrons are released
-some energy is released

Huge amounts of water move in and out of river mouths each day because of the tides. A tidal barrage is a barrier built over a river estuary to make use of the kinetic energy in the moving water. The barrage contains electricity generators, which are driven by the water rushing through tubes in the barrage.

Where is Tidal Energy Used?

As tidal power generation is relatively new, there are not a lot of tidal energy companies out there developing investing in this technology yet. However, there are several tidal power plants in use and more is coming. Some of these are solely for research and experimental purposes, but the number of commercial tidal energy power plants is increasing.

La Rance tidal power station was the first large large-scale tide energy project and was opened already in 1966. It lays in the water-rich river Rance in the north-western France. This is a tidal power plant with a total installed capacity of 240 MW capacity generated from 24 turbines. Annual production of electricity is about. 0.6 TWh (600 GWh), which means that the average effect of day throughout the year is 68 MW. La Rance is a form of what we call a tidal barrage power plant.

The waste produced is only dangerous if the promoters don't use it properly.
i.e if proper disposal is supplied, it is harmless to the environment and anything around it

Pros:
-it easily burns unlike fossil fuels so no co2 or other greenhouse gases are emitted so reduces pollution
-it has a high power output
- only a small amount of fuel is needed sompared to coal/ oil
-reliable, unlimited supply even in disaster
- safe when promoters use it properly
- The lifetime of nuclear power station is about 20 years

Cons:
-hazardous radioactive waste is produced
-building the power station is quite expensive
-if proper disposal isn't supplied then it's harmful to the environment

Wind farms have been used throughout history as one the first energy.First used to power boats and grind grain.The Chinese have also used them even was a pump for pumping water.
