1.3.1 Renewable and Non-Renewable Energy Resources

• What are renewable energy resources?

  Sources replenished naturally
• Renewable energy resources are considered sustainable because they can be used without being exhausted
• What is the source of wind energy?

  Wind currents
• Geothermal energy uses heat from the Earth's internal heat.
• Match the renewable energy source with its corresponding non-renewable source:

  Solar ↔️ Fossil fuels

  Wind ↔️ Nuclear

  Hydroelectric ↔️ None
• Renewable energy sources, unlike fossil fuels, are sustainable.


  True
• What is a potential drawback of solar energy?

  Dependent on weather
• Many renewable sources like solar and wind are intermittent and weather-dependent.


  True
• What are two potential drawbacks of renewable energy sources mentioned in the study material?

  Intermittency and land use
• Many renewable sources like solar and wind are dependent on weather
• Renewable energy sources produce greenhouse gas emissions.

  False
• How does transitioning to renewable energy improve a country's energy security?

  Reduces reliance on imports
• Match the drawback of renewable energy with its explanation:

  Intermittency ↔️ Dependent on weather conditions

  Land Use ↔️ Requires large areas of land

  Cost ↔️ Expensive implementation
• Match the renewable energy source with its source:

  Solar ↔️ Sunlight

  Wind ↔️ Wind currents

  Hydroelectric ↔️ Flowing water

  Geothermal ↔️ Earth's internal heat
• Hydroelectric energy is carbon-free and reliable.


  True
• Geothermal energy is location-specific and may release harmful gases.
• Renewable energy sources reduce greenhouse gas emissions.


  True
• Why are renewable energy sources considered sustainable?

  Replenished naturally
• Transitioning to renewable energy can reduce reliance on imported fossil fuels.
• Renewable energy projects require minimal land compared to fossil fuel plants.

  False
• Why can renewable energy sometimes be more expensive than fossil fuel-based power generation?

  Higher initial implementation costs
• Renewable energy sources are sustainable because they can be replenished naturally
• What are the two main types of non-renewable energy resources?

  Fossil fuels and nuclear energy
• Fossil fuels are formed from the remains of plants and animals over millions of years.


  True
• Compared to renewable energy, non-renewable sources contribute to greenhouse gas emissions
• What radioactive element is used to derive nuclear energy?

  Uranium
• What is the primary characteristic of renewable energy resources?

  Replenished naturally
• Match the renewable energy source with its corresponding non-renewable counterpart:

  Solar ↔️ Fossil fuels

  Wind ↔️ Nuclear
• Solar energy is derived from sunlight
• Fossil fuels like oil, gas, and coal are non-renewable resources.


  True
• Sustainability is a key advantage of renewable energy because it ensures resources can be replenished naturally
• Non-renewable energy resources contribute to greenhouse gas emissions.


  True
• How are fossil fuels formed?

  From the remains of plants
• Unlike renewable energy sources, non-renewable resources are finite
• What is the primary environmental impact of using fossil fuels?

  Greenhouse gas emissions
• Non-renewable energy sources like fossil fuels and nuclear power are finite resources that will eventually be depleted
• Non-renewable energy sources are sustainable in the long term.

  False
• What happens to non-renewable resources when they are used?

  They are exhausted
• Match the energy resource with its example:

  Renewable energy ↔️ Solar power

  Non-renewable energy ↔️ Fossil fuels
• Non-renewable energy resources can be replenished within a human lifetime.

  False
