Importance of Renewable Energy Sources

Today world is great danger. We need to save our earth. Our environment is polluted day by day. There is soil pollution ,air pollution, water pollution etc. We need to prevent that to save our world. For that reason we need to look other option to our energy resources. We have wind and sun in our hand to utilize.
We look bigger companies to provide our electricity. But each and everyone has the capacity to produce own electricity at our homes. We can install solar panels at our homes and also can install wind turbine. These are the thing that's saves our energy. These are energy called alternative energy. These are the alternative energy drastically reduce carbon emission. In this way we alternative energy saves our earth.
Every one has to play his own part to save our earth. Each and every people do everything to reduce carbon emission on the earth. On the other hand if we look closely by installing our energy resources at our homes w can save money. For example if we install solar panel at our homes we can utilize right amount of energy and also can save our electricity bill. On the other hand excess amount of electricity can be distributed to the other homes also. In this way we can gain some money also.
But there is problem to face. We need good amount of money to installing its system. My be look to take help form the solar company to install solar panel to our homes. It makes it costly. But every problem has solution. There are constant way to develop less costly system. It is in the process. So in near future we expect less costly system.

Renewable energy

We need energy to run our lives. Therefore we require energy security. Today energy security is much more in crisis. Petroleum products becoming more less and less day by day. But we need alternative energy resources. Renewal Energy is one that option that we have today. It is also have to notice that we need to cut our carbon emission today by huge margin. We have to look our future to stay properly.Carbon emission is a big problem today. It causes to heat stay in the ground. And in effect average heat in the ground getting bigger and bigger. So we need some kind of alternative. Renewal or Green energy is alternative of fossile fuel.

There are many renewal energy technologies today. They specially contribute to world energy security. It helps to reduce to dependency on the other fuel. There are different technology. And they are known as First generation technology, second generation technology and at the last Third generation technology.

First generation technology-
In this type of technology includes hydro power, biomass combustion,geothermal power and heat.

Second generation technology-
In this type of technology includes wind power,solar heating and cooling, solar photostatic and bioengineering.

Third generation technology-
It is still under development which is include ocean energy, advanced biomass gasification, solar thermal power etc.
