What Are Five Alternative Energy Sources?
When it comes to alternative energy, there are five major examples. This article will provide you insights and you will find out what the top five alternative energy sources are. With these examples, you will get to learn some of the common advantages and disadvantages because they all come with flaws. Before we learn what the five alternative energy sources are, it is important to know what these alternatives really are and how they help. They are sources that consist of clean energy sources and others. They are popular because unlike more traditional sources, many do not harm the environment.
The Five Top Sources
The first example of the five alternative energy sources is wind power. This utilizes the power of wind turbines which are propelled by the blades therein. This is a clean energy source that is suitable in areas where wind levels are sustainable. The first advantage is that it is a clean energy as mentioned. The other point is that it is renewable meaning that it can never get depleted. Another thing is that activities like farming can go on as usual in an area where turbines are. The downsides are that not all places can harness this power because the wind capacity is too low. Another thing is that large wind farms will derive the scenic beauty of a place. The second example of the five alternative energy sources is the sun.
Solar power definitely tops the list of favorites when it comes to the five alternative energy sources. This power has been used for a long time for cooking, heating and to produce electricity. Solar panels are installed to ensure that electricity is gotten. Just like the other five alternative energy sources, it comes with its fair share of upsides and downsides. The advantages include the following. It is renewable, it does not pollute the environment and it has a wide variety of applications. The major disadvantages include the following. First, it can only be harnessed when the sun is shining and the night and cloudy days will not work well with this regard. It is expensive to establish solar power plants.
The other example of the five alternative energy sources is earth heat which is mainly called geothermal energy. This heat under the earth is able to heat water and produce steam. It is one of the best five alternative energy sources. The steam is used to drive turbines after it is purified. These turbines power electric generators that get the electricity running. Geo-thermal plants are very self-sufficient once built and they produce useful by-products. When they are built incorrectly harmful by-products may be emitted instead. The other sources are biofuels like maize and sugarcane.
