Renewable Energy Sources

Introduction

• Renewable energy sources are sustainable and naturally regenerate over human timescales.
• They play a crucial role in reducing our reliance on non-renewable fossil fuels.

Historical Perspective

• Before the 18th century, most energy sources were renewable.
• Examples include water wheels, windmills, and burning wood for heating and cooking.

Types of Renewable Energy Sources

• Renewable energy sources include solar, wind, wave, tidal, and hydroelectric power (HEP).
• These sources harness the power of nature to generate electricity.

EU Renewable Energy Statistics (2016)

• In 2016, renewables contributed 44% of the EU's electricity capacity.
• They accounted for 15% of the EU's final energy consumption.

Solar Power

• Solar panels capture energy from the sun's rays and convert it into electricity.
• Solar power is clean and abundant, making it an important renewable energy source.

Wind Power

• Wind turbines use the kinetic energy of the wind to generate electricity.
• Wind power is a rapidly growing renewable energy source worldwide.

Hydroelectric Power (HEP)

• HEP harnesses the energy of flowing water to generate electricity.
• Dams and turbines are used to capture this energy.

Wave and Tidal Energy

• Wave and tidal energy capture the movement of ocean waves and tides.
• They are still emerging technologies but hold great potential.

Environmental Benefits

• Renewable energy sources produce little to no greenhouse gas emissions.
• They help combat climate change and reduce air pollution.

Economic and Energy Security

• Investing in renewables can boost local economies and reduce reliance on imported fossil fuels.

Summary

• Renewable energy sources, including solar, wind, HEP, wave, and tidal energy, offer sustainable and environmentally friendly alternatives to fossil fuels.
• They play a significant role in reducing greenhouse gas emissions and ensuring a more secure and sustainable energy future.
