what are the advantages and disadvantages of thermal power?

Answer 1

I am assuming that by thermal you mean "heat" which is how Websters dictionairy describesmost versions of thermal. Thermal power is provided by several sources, all of which have thierown advantages and disadvanteges but you would need to seek out each source and decide those for yourself.

Answer 2

Geothermal power is utilising the heat of the earth to make steam to turn turbines, or using naturally occurring steam. Its advantages are that it requires no fuel (and thus no greenhouse gases) to gebnerate electricity. Disadvantages are limited availability - it is only available in limited parts of the world. You generally have to drill a very deep hole. The steam can also have many other dissolved compounds which can be highly corrosive.
