6.2.1 Renewable Energy Adoption

• Renewable energy is naturally replenished
• Match the type of renewable energy with its example:

  Solar ↔️ Solar panels on rooftops

  Wind ↔️ Wind turbines in wind farms

  Hydroelectric ↔️ Dams and hydropower plants

  Geothermal ↔️ Geothermal power plants
• Wind energy harnesses the kinetic energy of wind
• Intermittency in renewable energy supply is caused by fluctuating weather
• What is the definition of renewable energy?

  Naturally replenished, indefinitely usable
• What type of renewable energy uses sunlight to generate power?

  Solar
• Non-renewable energy sources are naturally replenished over time.

  False
• Which renewable energy source uses flowing water to generate electricity?

  Hydroelectric
• What is one key characteristic of renewable energy replenishment?

  Naturally replenished
• The key types of renewable energy are solar, wind, hydroelectric, geothermal, and biomass
• Adopting renewable energy reduces greenhouse gas emissions, lowers environmental pollution, and preserves natural resources
• Lower operating costs and job creation are economic benefits of renewable energy.


  True
• What is intermittency as a challenge in renewable energy?

  Fluctuations in energy supply
• Large land areas are required for renewable energy facilities like wind farms and solar plants
• What is a renewable energy target set by governments?

  Mandatory share of renewable energy
• What is one challenge faced by the Solar City initiative in India?

  Grid integration and storage
• Order the case studies of successful renewable energy initiatives based on their primary source of energy:

  1️⃣ Geothermal Power in Iceland

  2️⃣ Denmark's Wind Power

  3️⃣ Solar City in India
• Renewable energy sources are unsustainable and environmentally damaging.

  False
• Each type of renewable energy is defined with a brief description and clarifying example.


  True
• What are two environmental benefits of renewable energy compared to non-renewable energy?

  Reduced pollution and emissions
• One of the challenges of transitioning to renewable energy is high initial costs
• Match the renewable energy challenges with their descriptions:

  High Initial Costs ↔️ Significant upfront investment in infrastructure

  Intermittency ↔️ Fluctuations in energy supply

  Land Use ↔️ Large areas required for facilities

  Social Acceptance ↔️ Concerns about aesthetics and noise
• Feed-in tariffs guarantee a fixed, above-market price for renewable energy generated electricity.


  True
• Denmark's wind power initiative succeeded due to long-term government support and investment in wind turbine manufacturing
• Renewable energy accounts for over 50% of Denmark's electricity generation.


  True
• Geothermal power in Iceland relies on abundant geothermal resources
