Explanation

• Wind energy depends on the speed and consistency of wind.
• If wind is low or stops, electricity generation decreases or stops.
• That’s why it is considered unreliable compared to fossil fuels.

Explanation

• Rising factory output directly increases energy consumption in the industrial sector.
• Factories use energy for machines, production processes, and heating.
• So when production increases, industrial energy demand also increases.
• This sector is the largest consumer of commercial energy in most economies.

Explanation

• Natural gas is mainly transported through pipelines over long distances.

• Pipelines provide a safe, continuous, and cost-effective method of transport.

• For long overseas transport, natural gas is converted into LNG (Liquefied Natural Gas).

Explanation

• Biomass energy is produced from organic matter such as plants, animals, and waste materials.

• It includes wood, crop residues, dung, and food waste.

• It is a renewable energy source because it can be replenished naturally.

• It releases energy when burned or converted into biogas or biofuels.

• It helps reduce waste and provides an alternative to fossil fuels.

Explanation

• Coal energy is considered suitable for base-load power generation because coal can be stored and supplied continuously.
• Base-load power means electricity supplied continuously to meet constant demand.
• Coal power plants can operate 24 hours a day.
• Major base-load energy sources: Coal, Nuclear, Hydroelectric, Natural Gas, Geothermal.
• China is the world’s largest producer and consumer of coal.
