Study Notes

Climate Change and Renewable Energy

  • Climate change is a major global challenge
  • Renewable energy is a sustainable solution to mitigate climate change
  • Renewable energy sources are replenished constantly.
  • Includes solar, wind, hydro, geothermal, and biomass.

Solar Energy

  • Harnesses power from the sun

Wind Energy

  • Captures kinetic energy of moving air

Hydro Energy

  • Derived from the movement of water
  • Used for centuries.

Geothermal Energy

  • Leverages heat from Earth's surface

Biomass Energy
