Are you aware that most of the earth’s electrical power is derived from the burning of coal? And that this is more than likely one of the chief sources of the greenhouse gases that are causing global warming and climate change.
It really is difficult to visualize that each time you turn on a kitchen appliance that you will be in part responsible for the discharge of toxins into the air, but in fact that is exactly what is actually happening.
Estimations differ, but it’s known that in the United states approximately one half of the electric power produced is derived from the burning of coal. In China, the planets most populous country, coal comprises above 70% of the nation’s energy usage.
Coal is burned to generate heat, and then the high temperature is used to turn water into steam. This vapor is put under pressure and then forced over turbines, which causes the turbines rotate. It’s the rotating of the turbines that makes the electricity.
Although there are alternative sources of high temperature to create steam (e.g. nuclear fission, geothermal, and natural gas amongst others) coal is by far and away the most frequent energy resource employed.
Burning coal releases various greenhouse gases along with other harmful materials straight into the atmosphere. Some of the air-borne pollutants emitted are:
- CO2 – the biggest contributor to climate change,
- SO2 (Sulphur Dioxide) – which causes acid rain when mixed with water,
- Nitrogen Oxide – a major cause of smog
- Carbon Monoxide (CO) – a poison which can be fatal (CO2 is also found in car exhausts)
- hydrocarbons and volatile organic compounds
- deadly metals for example mercury and arsenic
- lead and cadmium
Power generation companies, like any other company, respond to demand from customers. If there is need for electric power then someone can make big dollars from delivering it! And while burning coal is the most efficient techniques to generate the electricity, then it will, of course, remain in use.
Consequently, in a very real sense, each and every time you switch on an appliance or lightswitch, someplace there will certainly be coal being burnt to create that electrical power.
There are numerous renewable sources of electric power that are starting to become more common. Wind power, solar power, and even wave power are being harnessed and turned into electrical energy. In the superior technological era we are now living in almost any form of energy can be transmuted into electrical power.
And with breakthroughs in technology it means that capturing this energy for your own personal use is getting to be much more feasible. In fact a lot of people are looking to go off-grid, generate their very own electrical power and as a result reduce the requirement for electrical power created through burning coal.
To find out even more about just how producing your own electricity supply may be achieved, have a look at this article regarding how simple it is to assemble your very own residential windmills and begin to harness some free environmentally friendly and endless energy source for yourself.
