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.
