Solution
The correct option is A A and B only
Geothermal energy is energy obtained from the earth's molten core where temperatures are so high where underground water is converted to steam with high pressure. This steam can be used to generate electricity at geothermal plants.
Hydropower plants store water a height. When this water is allowed to flow, they can be used to turn turbines to generate electricity.
Hence, these are good alternatives to coal in power stations.
