For example:
A car’s gas tank is filled with (liquid) petroleum in order to move. The combustion engine in a car combusts and ignites the petroleum (as it is extremely flammable) and converts this power into energy used to put pressure on the car pistons and move the car wheels. This happens constantly throughout the car journey and is the explanation behind a car moving forward.
Although there are many advantages to using fossil fuels, there are many disadvantages also. Firstly, the fossil fuels on earth are quickly depleting and, scientists and geologists say that within the coming 70 years, our entire source of fossil fuels will be used up by humans; Thus leaving a need for alternate energy supplies in the generations to come.
The second problem with the use of fossil fuels is that, when burnt, they release immense amount of Carbon Dioxide into the environment. This issue has been impacting the world greatly over the past 50 years (mostly) and if the economy continues this path of destruction, then the earth will turn into our garbage can.
Hydrogen is an energy carrier. It is not a direct source of energy, however when reacted with oxygen, it is a very powerful source of energy.
Energy carriers move energy in a usable form from one place to another. Electricity is the most well-known energy carrier. We use electricity to move the energy in coal, uranium, and other energy sources from power plants to homes and businesses.
Hydrogen is not widely used today but it has great potential as an energy carrier in the future. Hydrogen can be produced from a variety of resources and is a by-product of other chemical processes. Unlike electricity, large quantities of hydrogen can be easily stored to be used in the future.
Hydrogen can also be used in places where it’s hard to use electricity. Hydrogen can store the energy until it’s needed and can be moved to where it’s needed.
There are 8 main types of renewable energy. They are:
- Biomass
- BioFuels
- Geothermal
- Hydro-Power
- Solar Power
- Tidal Power
- Wave Power
- Wind Power
Renewable energy is a much safer, cleaner source of energy. It is from natural resources, such as sunlight or wave power from oceans or rivers. The majority of renewable energy technologies are directly or indirectly powered by the sun.
