With reference to Blue Renewable Energy Sources, consider the following
statements —
1. Tidal energy is generated using turbines placed in tidal streams or barrages.
2. Ocean Current Energy uses the temperature difference between warm surface
water and cold deep water to generate power.
3. Ocean Thermal Energy Conversion (OTEC) utilises the kinetic motion of surface
waves to produce electricity.
Which of the above statements is/are correct?
Explanation - Blue Renewable Energy Sources refer to sustainable energy derived
from the
ocean's natural forces, including tidal waves, ocean currents, and thermal gradients.
These
sources harness the immense power of the sea to generate electricity without
emitting
greenhouse gases, making them a clean and eco-friendly alternative to fossil fuels. Key
types of blue renewable energy include —
• Tidal Energy — Generated from the rise and fall of tides, tidal energy uses turbines
placed
in tidal streams or barrages to produce electricity.
• Wave Energy — Captures energy from surface waves using floating devices or
underwater
systems, converting the kinetic motion of waves into power.
• Ocean Current Energy — Utilises the continuous flow of ocean currents to turn
underwater
turbines, generating consistent and predictable electricity.
• Ocean Thermal Energy Conversion (OTEC) — Exploits the temperature difference
between warm surface water and cold deep water to generate power, often using a heat
engine.
Blue renewable energy holds significant potential for sustainable power generation,
particularly for coastal and island nations, providing a reliable and environmentally
friendly energy solution.
