Conventionally, electricity is created by converting heat energy to mechanical energy to electrical energy. This is completed by rotating massive turbines that may turn electromechanical generators that may generate electricity. The process of moving these gigantic turbines is usually by boiling giant quantities of water and using the steam to show the turbines. To heat the water, fuels are needed. The most commonly used fuels for this objective are:
Fossil fuels and coal. These non-renewable resources are mined from deep layers of the earth and are one, if not a very powerful commodities of the today’s energy-hungry world.
Nuclear fission. This chemical process of splitting atoms into smaller components produce heat that can be used to boil the water and generate steam.
Bio-mass or bio-waste. These are biological waste from natural organism reminiscent of plants and animals which can be used instead of fossil fuels to produce heat.
Generally, different forces or energy are used to move the turbines without heating up the water for steam.
Hydro-energy is the process of using the kinetic energy of running water such as rivers, falls, tides, etc. to create mechanical energy that can rotate the turbines.
Wind is also another option to get the generators moving and convert mechanical energy to electrical energy, without the need for burning fuels and the heat.
If there are lots of options to generate electricity, why do we have to conserve it?
It’s because despite of those different alternate options, most energy companies still rely largely on burning fuels, notably fossil fuels and coal, to create mechanical energy that can in flip be used to generate electricity. And because these types of fuels are non-renewable, we are running the risks of energy scarcity as soon as we have used up the world’s fossil and coal deposits.
At this time, we’re nonetheless heavily dependent on these energy companies to provide us with electricity to run our household and our lives. In effect, we are also promoting using these non-renewable sources because that is how it’s always been. However we can not avoid the upcoming truth and the energy crisis that we’re facing.
Various teams and people at the moment are advocating different energy sources to acquire energy and preserve whatever now we have left. And as if to encourage us more, these green and various energy options have one wonderful consequence: free electricity for us to enjoy!
