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.
