Hydel Power's Contribution to Global Electricity

This question asks us to identify which energy resource is responsible for generating about one-fourth of the world's total electricity. Let's break down the main electricity production methods.

Exploring Hydel Power Generation

Hydel power, often called hydroelectricity, harnesses the energy from moving water. Large dams store water, and when released, the water flows through turbines connected to generators. This process converts the kinetic energy of water into electrical energy.

Globally, hydel power is a major contributor to the electricity supply. Statistics show that hydroelectricity consistently accounts for approximately 24% to 25% of the world's electricity, fitting the description of one-fourth.

Analysis of World Electricity Resources

To understand the significance of hydel power, consider the other main sources:

• Thermal Power: Generated by burning fossil fuels (coal, natural gas, oil). It's the largest source globally but is non-renewable and causes pollution.
• Nuclear Power: Uses nuclear reactions to generate heat, producing electricity. It's a significant low-carbon source but has challenges with waste and safety.
• Solar Energy: Utilizes sunlight via panels. It's a growing renewable source, but its global share is currently smaller than hydel power.
• Other renewable sources like wind, geothermal, and biomass also play roles.

Significance of Hydel Power Resource

The widespread infrastructure of hydroelectric dams allows hydel power to provide a stable and substantial amount of electricity consistently. Its role in supplying around one-fourth of global electricity highlights its importance as a key energy resource.

Therefore, hydel power is the primary resource responsible for producing approximately one-fourth of the world's electricity.
