Question : Which non-conventional energy source depends on the sun's heat?
Option 1: Wind energy
Option 2: Tidal energy
Option 3: Geothermal energy
Option 4: Solar energy
Correct Answer: Solar energy
Solution : The correct answer is (D) Solar energy
Solar energy is a non-conventional energy source that relies on harnessing the heat and light from the sun. Solar panels or photovoltaic cells convert sunlight into electricity, and solar thermal systems use the sun's heat for heating water or air. Solar energy is a renewable and sustainable source of power that can be used for various applications, including electricity generation, heating, and powering devices.
Question : Statement 1: Geothermal energy is a renewable source of energy derived from the heat of the Earth's interior.
Statement 2: Geothermal power plants convert geothermal heat into electricity through steam turbines.
Question : The energy that can harness heat stored below the earth's surface is known as:
Question : Statement 1: Geothermal energy is a reliable and consistent source of power as it is not dependent on external factors like weather conditions.
Statement 2: Geothermal power plants utilize the heat generated by the Earth's core to produce electricity.
Question : Statement 1: Wind power is a clean and renewable source of energy that harnesses the power of wind to generate electricity.
Statement 2: Wind turbines convert the kinetic energy of the wind into electrical energy.
