Which of the various methods of current generation protects the nature well. Give examples to support your answer.

Explanation

1) Now a days current is generated in so many ways like Hydel power, thermal power ,wind power, nuclear power , power from garbage,solar power,etc.
2) Each system has it own advantages and disadvantages.
3) Hydel and thermal power generation is the most commonly used methods.
4) If you consider Hydel power . IT uses a lot of water stored at a very higher places. Water is non-renewable source. Ground water level is decreasing day by day due to less rain fall, because of Global warming which is a consequences of pollution. Therefore this Hydel power must be used only in rainy season.
5) Thermal pwer is produced from coal.Coal is also a non-renewable source and also it is limited to a certain area. The process of production involves a lot of pollution by means of ash. Nowadays some measures are taken by the managements to reduce pollutions by utilising the ash in the production of cement and bricks . But the major source i.e,coal is non-renewable . SO this is also does not protect nature.
6) The alternate power generating system like wind power.solar power protects nature wind power and solar power are renewable sources. But they have some limitations like ,non-avaibility at all times, more production cost,less storage capacity etc. Researches should be done in reducing the cost of productions and increasing the storage capacity.
7) The other sources like nuclear power, power from tides,Geothermal electricity etc. are to be improvised and they have to be brought into the wide usage.Then the nature will be protected well.
