P8.2 Powering Earth

• What are the two main types of energy sources discussed in this material?

  Renewable and non-renewable
• How can technological advances influence energy needs?

  Increase or decrease
• Non-renewable energy sources are infinite and sustainable

  False
• What is the definition of a renewable energy source?

  Replenished naturally
• What is one advantage of nuclear power as a non-renewable source?

  Lower carbon emissions
• Nuclear power is considered a renewable energy source

  False
• What is one major disadvantage of non-renewable energy sources?

  Contribute to climate change
• Efforts to reduce carbon emissions can lower overall energy needs
• Non-renewable energy sources contribute to climate change and environmental pollution
• Renewable energy sources produce greenhouse gas emissions during use.

  False
• Why are renewable energy sources considered intermittent and unreliable?

  Dependence on weather conditions
• What is a disadvantage of renewable energy sources in terms of cost?

  More expensive to set up
• Order the strategies for transitioning to sustainable power:

  1️⃣ Increasing Renewable Energy

  2️⃣ Improving Energy Efficiency

  3️⃣ Reducing Fossil Fuel Dependence

  4️⃣ Advancing Energy Storage
• What is a key area for improving energy efficiency?

  Building insulation
• Increasing population leads to higher overall energy consumption
• Environmental concerns can lower overall energy needs
• Why are renewable energy sources considered more environmentally friendly?

  No greenhouse gas emissions
• Non-renewable energy sources are finite and will eventually be depleted
• Increasing population leads to higher overall energy consumption
• Match the energy source with its key advantage or disadvantage:

  Renewable energy ↔️ Environmentally friendly

  Non-renewable energy ↔️ Cheaper and reliable
• Policymakers must consider the trade-offs between energy sources to develop a sustainable energy strategy


  True
• What is one example of a renewable energy source that relies on moving air?

  Wind energy
• What are examples of renewable energy sources?

  Solar, wind, hydroelectric, geothermal, biomass
• What is the definition of renewable energy sources?

  Sources that can be replenished naturally
• Non-renewable sources like fossil fuels are cheaper but contribute to climate change
• Non-renewable energy sources provide a reliable and consistent energy supply
• Renewable energy sources can affect aquatic ecosystems during hydroelectric power generation.


  True
