The problems with current power generation systems are
1) Hydel Power: Severe Impact of the Eco systems, Huge cost. many People are rendered Homeless. Plant & Animal species goes extinct.
Your heritage is also Impacted a Big way.
2) Thermal Power: cheaper to built than hydel Power but they also Impact in a big way. most plants are Lignite based. they are responsible for creating air pollution.
3) Nuclear power: In my opinion its the worst method of generating power, as Till date Man kind can't find a way what to do with the radio active waste produced in the process. If any earth quake comes or any other nautral calamity then the results be Disastrous.
