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.
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 wind power as a clean and renewable source of energy that utilizes the power of wind to generate electricity. Wind power is considered clean because it does not produce greenhouse gas emissions or other harmful pollutants during operation. It is also renewable because the wind is an abundant and naturally replenishing resource.
Statement 2 is also true. Wind turbines are designed to convert the kinetic energy of the wind into electrical energy. The rotating blades of a wind turbine capture the energy from the wind and transfer it to a generator, which converts the mechanical energy into electrical energy that can be used to power homes, businesses, and other electrical devices.
Both statements provide accurate information about wind power and its conversion into electrical energy.
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.
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: 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: Nuclear power is a non-renewable source of energy that involves the use of radioactive materials.
Statement 2: Nuclear power plants generate electricity through nuclear fission, which releases a significant amount 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.
