How solar energy works to produce electricity is not that hard to understand and that is why homemade solar panels are so easy and low cost to make.
Electrical power has been one of man’s greatest discoveries because it has helped to develop the world and it’s living standard to what they are today.The demand for electricity has just grown and grown as more and more countries throughout the world demand the energy that comes from this source. The ever increasing amounts of electricity is produced, largely by, using as its source depleting fossil fuels, nuclear fission, water, wind and of course the sun.
This article will explore the different methods of electricity production with an eye on how solar energy works.
Electricity is produced by complicated enormous turbines that are powered by the various sources mentioned above.
How Solar Energy Works Is Nothing Like This.
Electricity is produced by burning fossil fuels and when the blades of a turbine are turned by enormous amounts of concentrated steam. This steam is made by heating a lot of water with huge furnaces. The water is super heated by burning rapidly depleting fossil fuels like coal, petroleum, and natural gas. This method of producing electricity releases huge amounts of carbon dioxide in the atmosphere, thus severely polluting the air we breathe and damaging the planet.
Because of how electricity is produced it is important to turn to alternate methods of electricity production for long-term benefits. That is why so much time and effort has been spent, over the years, to fully understand how solar energy works.
How electricity is generated.
You have, no doubt, heard how dams are constructed to produce electricity. The Hoover Dam in Nevada USA is an example of this. It is a popular method for producing electricity, a water dam works by restricting the water flow of a river and channeling it to turn massive turbines, which produce electricity. Electricity generated this way helps the atmosphere and controls air pollution; however, this method of electricity production adversely affects the ecosystem by harnessing large bodies of water. It changes nature. At the moment water accounts for around ninety per cent of the world’s electricity that is generated through renewable resources.
Electricity is produced when wind energy is converted to electrical energy by the use of windmills or wind turbines that are used to capture high gusts of wind energy which is then converted into electrical energy. A wind mill captures the power of the wind and turns it into mechanical power to turn say a millstone. A wind turbine is employed to capture the energy produced by the wind and converts the wind energy into electrical energy for electrical work. A wind turbine typically consists of blades, a tower, a shaft, a base, and a generator. The blades of the wind turbine rotate in the wind to generate mechanical energy. The two pre-requisites for installing a wind turbine are a large area of at least one acre and an average wind speed of 11 miles per hour. The main problem with this is that the wind is variable. How solar energy works is by using an unvariable source the shining of the sun.
By nuclear fission:
Yes, nuclear fission does not only make atom bombs, but also helps produce electricity. Nuclear fission causes a chain reaction where the element Uranium is bombarded by neutrons causing it to split. Every time a Uranium nucleus is split, more neutrons are released, causing more splits in the already split Uranium nuclei. The resultant chain reaction generates a lot of heat which is used to heat water the steam of which eventually moves turbines to create electricity.
With technological advancements, electricity is also being produced by bio-waste. Bio-gas is a typical way of generating electricity in rural areas in countries like India. In fact, a new technology evolved in the state of Bihar in India that uses human waste to generate electricity.
How Solar Energy Works.
Solar energy works by harnessing the sun’s energy or the solar energy, which is the most abundant form of energy available on earth and turning this free energy into heat and light by using affordable solar panels. The sun is capable of giving us more than heat and light because it can be converted into electricity that generates power for our daily use.
With the advent of diy solar panels just about every one is able to benefit from the massive cost savings this brings. Learning how solar energy works and then harnessing it is time well spent.

And the end of the day the important thing is not how solar energy works but that it does work and we can save money and save the earth at the same time.
