Sources of Renewable Energy by Shantanu

To think about renewable energy we have to think about the sources of renewable energy first. There are various kinds of ways to produce renewable energy in the world. First one is Hydropower. Hydropower means generating electricity, using water. We can use a dam of a river to generate electricity. There will be small way out for the water and water will be stored in behind of the dam. Then water will be released through the narrow way out and on the way it will spin the turbine and that will generate electricity. This is a very old but successful way to generate electricity. By using this way we can generate huge electricity. But the problem of this energy source that the setup is huge and it may create problem for the wildlife in the water. The next is wind power. There will be three blades and the center of them there will be the generator, which will be generating electricity. Wind makes the blade turbine and the generator generates electricity. To get the strongest wind these blades are usually situated above a tall tower or something like that. Using wind power for electricity is very popular because this is totally pollution free. The next is solar power. Solar is manmade plate by which electricity can be generated by using sunlight. This solar energy is expected to get bigger if the technology expands. But now the problem with the solar energy is it is not that much cost efficient and not provide expected electricity. The next one is biomass energy. In this way we can make electricity my using the gas formed by the wastes. We can store wastes in a vacuum place and produce burning gas and electricity or we can make bio fuel by directly heating the wastes. Biomass can meet needs regarding our electricity, burning gas and fuel for vehicles. One problem can occur that sometimes it may result toxic pollution if the wastes are directly from the municipal. These are the various kinds of renewable energy sources that we can use by not depending the natural resources.

Opinion

I have taken various kinds of renewable energy sources from the article. In this article I got all the renewable sources that exists now. If we can make a combination of all of the renewable energies we can make a pollution free world and can get all of our basic needs. In this article all of these renewable energy sources are being used in USA. It is described in a very good way that how much electricity USA can get from these sources. There are some limitations in the renewable sources. Limitations will be everywhere and we have to come up with solutions. It is far better to come up with a solution that can make the renewable sources perfect rather than using our natural resources to the end. Technology is developing and we hope in the very near future we can meet all our needs by only depending on the renewable sources.
