Renewed Energy



An energy is said to be renewable when the source has the ability to replenish itself. Thus, they appear to be more sustainable source of energy supply in the coming years. Most of all, since they don’t emit greenhouse gases and other toxic emissions that can harm the atmosphere and cause illnesses, there are several people who are in favor of the different types of renewable energy.
Common types of renewable energy

You would be surprised to know that there are definitely a handful of various types of renewable energy that it’s almost impossible that you would not be able to find the source even in your community. For a rundown of types of renewable energy, you can refer to the list below:
Solar energy

Of all the types of renewable energy, that coming from the sun is the most popular and widely used. After all, almost every part of the world can obtain sunlight one way or the other. They are also used as alternatives for fossil fuels, which can create holes in the ozone layer. In order to convert the energy coming from the sun into electricity, users make use of photovoltaic panels, which come in different sizes. Besides this, there are no other moving parts or components that need to be installed.
Hydroelectric Energy

One of the types of renewable energy, hydroelectricity derives its energy from flowing water. Normally, strong gushes of water, like the ones you can find in Niagara Falls, can already generate useful power. The force will eventually turn the turbines, which will then case the generator to move and create electricity. The latter is then distributed to different homes all over the community. Like other types of renewable energy, this doesn’t create any smoke and hence doesn’t cause any form of pollution. Moreover today it’s highly possible for homes to generate their own hydroelectric power without building huge dams.
Wind Energy

Of all types of renewable energy, this is considered to be the oldest. In fact, earliest civilizations made use of the wind to further their economy, especially in farming and irrigation. Nowadays, the wind, like other types of renewable energy, can also be used to generate the much-needed electricity in many towns and homes. Wind turbines as high as 100 feet are erected in a very windy area. The shaft, on the other hand, forms the rotor, which is then connected to a generator. When the former turns, it will then activated the latter, producing electricity.
