Renewable Energy

Definition: Energy derived from naturally replenishing sources such as sunlight, wind, rain, tides, waves, and geothermal heat.

Relevance to home energy efficiency: Renewable energy sources can provide clean, sustainable power for homes, reducing reliance on fossil fuels and lowering carbon emissions.

Benefits:

  • Reduces carbon footprint
  • Can lead to energy independence
  • Often has lower operational costs once installed

Drawbacks:

  • High initial installation costs for some technologies
  • Intermittent nature of some sources (e.g., solar, wind)
  • May require significant space or specific geographical features

Statistics: The International Energy Agency reports that renewable energy is set to account for almost 95% of the increase in global power capacity through 2026, with solar PV alone providing more than half the increase.
