Renewable vs non-renewable energy

Science · Energy · conceptual

Distinguish between renewable energy resources (solar, wind, hydroelectric, tidal, geothermal, biomass) and non-renewable resources (coal, oil, gas, nuclear), comparing their advantages, disadvantages, and environmental impacts

Sign in to track this

What mastery looks like

  • Lists at least four renewable and three non-renewable energy resources
  • Explains what makes a resource renewable or non-renewable
  • Compares the environmental impact of at least two different energy sources (e.g. wind vs coal)
  • Discusses trade-offs between cost, reliability, and environmental impact in choosing energy resources

Check your understanding

If Renewable vs non-renewable energy heard about a plan to build a new wind farm in your area, could they explain what the advantages and disadvantages would be compared to a gas-fired power station — both for the environment and for reliability?
