The correct answer is: d) Wind power potential.
Gujarat has a long coastline of about 1,600 kilometers. This coastline is ideal for the generation of wind power. Wind power is a renewable source of energy that does not produce greenhouse gases. It is also a cost-effective source of energy.
The other options are not as advantageous for power generation in Gujarat. Geothermal potential is the potential to generate electricity from heat that is generated within the Earth’s crust. Tidal power potential is the potential to generate electricity from the tides. Access to coal imports is not an advantage for power generation in Gujarat because coal is a non-renewable source of energy that produces greenhouse gases.
In conclusion, the advantage of Gujarat’s long coastline for power generation is its wind power potential.
