Knowledge of Renewable Energy

Energy is a precious property of objects to human beings which can be converted into different forms or transferred to other objects. It cannot be created or destroyed. We may hear the words such as renewable energy, natural energy, clean energy, solar energy, sustainable energy etc. And we also they are important to us. But few of us know a lot of them. Today I am going to tell something about renewable energy.

What is Renewable energy?

It is the energy of natural resources such as sun, wind, rain, tides, and geothermal heat renewable natural. Renewable energy technologies including solar energy, wind energy, hydropower, transport of micro hydro power, biomass and biofuels.

Renewable energy in Singapore is in the process of natural energy, constantly added.This includes the sun, wind, geothermal, tidal, water, and all forms of life.This energy cannot be exhausted, constantly updated.

We should also know what is alternative energy.

Alternative energy is an energy term, however,which is a substitute for fossil fuel.In general, it shows that unconventional energy and low environmental impact.The term alternative is used to contrast with fossil fuels according to some sources. By most definitions alternative energy doesn't harm the environment, the difference between renewable energy and may or may not have a significant impact on the environment.

There is a lot of renewable energy, and is considered to be environmental protection, the use of natural process.

Solar energy is the most ideal renewable energy due to the resources are inexhaustible, clean and safe.

Wind energy is another important renewable energy. Increasing the development and utilization of wind energy has become the consensus of the global energy sector. Wind power generation has resulted in annual output value of more than 5 billion-dollar in the world. More than 50 countries are actively promoting the development of wind energy.

One of the renewable energy is tidal energy.It can be generated in two ways, after a spate of tidal stream generators or generation. Tidal stream generators generally more environmentally friendly and the effects on the existing ecological environment more small.Is similar to a wind turbine, many tidal stream generators rotate underwater, is the rapid flow of dense water. Although has not been widely used, tidal power will use in the future. Tidal more predictable than wind energy and solar energy. Historically, tide factory in Europe and the United States on the Atlantic coast. The emergence of the earliest can be traced back to the middle ages, or even from Roman times. Tidal force produced by the moon and the sun, in combination with the earth's rotation, is responsible for the generation of the tides. The moon energy company announced that they will build the world's first tidal power plant on the coast of wales. This will be the world's first deep-sea tidal power plants, supply power for 5000 homes.Eight underwater turbines, each 25 metres long and 15 meters high, installed in the bottom of the sea of st David peninsula.Construction will begin in the summer of 2008, the tidal generators, described as a wind from the bottom of the sea, should be put into use in 2010.

Using renewable energy not only can save resources and eliminate waste but more efficient with lower consumption and fewer emissions than using primary resources. In addition, the healthy and rapid development of renewable energy industry will give impetus to the development of a large number of related industries, and create jobs for the city.
