Green energy

At the moment,the issue of a possible shortage of energy is more actual than ever. That's because most energy that is spent by humans is finite. But we must keep in head that there is an available alternative:natural or green energy. It makes me want to emphasize clear benefits of natural energy:the green energy is renewable,I think this aspect will help us to escape the deficit of energy,the second one is that the green energy is environmentally-friendly which means it isn't harmful for the nature at all. Actually,it's the part of it.

Usually when you say ''natural energy'' you probably mean solar,wind power,hydroelectric power. So let's watch each case of profit of differents types of natural energy.

      SOLAR                               
Solar cells can be used to generate electricity from sunlight. It is a device that converts light energy into electrical energy. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight.

        WIND POWER
One of the most popular uses of wind energy today is for wind power generation. During this process, a wind turbine is used to harness the energy of the wind. As the wind starts to move the turbine blades, a generator starts to turn which then produces electricity.

HYDROELECTRIC ENERGY
Hydropower is energy collected from flowing water that's converted into electricity or used to power machinery. Hydropower has been around for centuries, used to turn millwheels or drive early industrial machinery, but in modern use it typically refers to electrical generation. 


Overall,I want to say that using green energy is a great opportunity to keep in safe of energy shortage and save our environment. I hope soon it will be the normal practice to produce electricity by using natural energy.
