Question : Statement 1: Hydropower is a renewable source of energy that harnesses the energy of flowing or falling water to generate electricity.
Statement 2: Dams and turbines are used to convert the potential and kinetic energy of water into electrical energy.
Option 1: Both statements are true.
Option 2: Statement 1 is true, and Statement 2 is false.
Option 3: Statement 1 is false, and Statement 2 is true.
Option 4: Both statements are false.
Correct Answer: Both statements are true.
Solution : The correct answer is (a) Both statements are true.
Statement 1 accurately describes hydropower as a renewable source of energy that utilizes the energy of flowing or falling water to generate electricity. Hydropower is considered renewable because water is naturally replenished through the water cycle.
Statement 2 complements Statement 1 by explaining the process of converting the energy of water into electrical energy. Dams are constructed to create a reservoir, and turbines are used to capture the potential and kinetic energy of the water, which then rotates the turbine and generates electricity.
Both statements provide accurate information about hydropower and its generation process.
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.
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 : Statement 1: Renewable sources of energy are inexhaustible and can be replenished naturally.
Statement 2: Solar power, wind energy, and hydroelectric power are examples of renewable sources of energy.
Question : Statement 1: Solar energy is a renewable source of power that utilizes sunlight to generate electricity.
Statement 2: Photovoltaic cells in solar panels convert sunlight directly into electrical energy.
Question : Statement 1: Biomass is a renewable source of energy derived from organic materials such as crop residues and wood.
Statement 2: Biomass can be used to produce heat, electricity, and biofuels.
