6. How does biomass energy compare to fossil fuels?

Biomass energy differs from fossil fuels in several aspects:

Comparison with fossil fuels:

• Biomass energy is derived from organic matter, while fossil fuels come from ancient organic deposits that took millions of years to form.
• Biomass energy has the potential to be carbon-neutral if sustainably sourced, as the carbon released during combustion is offset by the carbon absorbed during the growth of biomass resources.
• Fossil fuels release carbon that has been stored underground for millions of years, leading to a net increase in atmospheric carbon dioxide levels.
• However, biomass energy may have lower energy density compared to fossil fuels, requiring larger quantities to generate the same amount of energy.

7. Can biomass energy help reduce greenhouse gas emissions?

Yes, biomass energy can contribute to reducing greenhouse gas emissions. Here's how:

• By utilizing biomass as a replacement for fossil fuels, the combustion process releases carbon dioxide (CO2) that was recently absorbed by plants during their growth.
• This carbon cycle makes biomass energy potentially carbon-neutral, meaning it doesn't result in a net increase in CO2 levels in the atmosphere.
• In contrast, burning fossil fuels releases carbon that has been sequestered underground for millions of years, adding to the overall greenhouse gas concentration.

8. How is biomass energy used for electricity generation?

Biomass energy can be used to generate electricity through different methods:

• Biomass power plants burn organic materials, such as wood pellets or agricultural residues, to produce steam that drives a turbine and generates electricity.
• Some biomass power plants utilize gasification or anaerobic digestion processes to convert biomass into biogas, which is then used to generate electricity.
• Biomass can also be co-fired with coal in existing coal-fired power plants, reducing greenhouse gas emissions and utilizing existing infrastructure.

9. What are some examples of biomass energy applications?

Biomass energy can be utilized in various sectors for different applications:

Applications of biomass energy:
