What is solid biomass as a fuel source?

Back

Solid biomass refers to organic materials, such as wood, agricultural crops, and waste, that can be used as fuel. It is considered potentially renewable but can lead to environmental issues like deforestation and soil erosion.

Why is nuclear energy considered non-renewable?

Back

Nuclear energy is considered non-renewable because it relies on uranium, which is a finite resource. Once depleted, it cannot be replenished within a human timescale.

What is co-generation in power plants?

Back

Co-generation is the simultaneous production of electricity and useful heat from the same energy source, increasing the overall efficiency of the power plant.

What is the role of uranium in nuclear energy?

Back

Uranium is the primary fuel used in nuclear reactors to produce energy through nuclear fission, where the nucleus of an atom splits, releasing a significant amount of energy.

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally in a short period (e.g., solar, wind), while non-renewable sources (e.g., fossil fuels, uranium) are finite and will eventually deplete.

Front

What are the advantages of using natural gas over coal?

Back

Natural gas burns cleaner than coal, producing fewer greenhouse gases and pollutants, making it a more environmentally friendly option for energy production.
