Frequently Asked Questions

1. Which is more sustainable: biomass or fossil fuels?

Biomass is more sustainable because it is renewable and carbon neutral. Fossil fuels are finite and add to atmospheric carbon.

2. Which is cheaper: biomass or fossil fuels?

Fossil fuels are generally cheaper at current prices. However, carbon pricing and incentives are narrowing the gap. Biomass costs are more stable.

3. Which has higher energy density?

Fossil fuels have higher energy density. Biomass requires more volume and weight for the same energy output.

4. Is biomass really carbon neutral?

Yes, when sustainably sourced. CO₂ released during combustion is absorbed by new growth, creating a closed carbon cycle.

5. Which has lower emissions?

Biomass has lower net CO₂ emissions and much lower sulfur emissions. However, it has moderate NOx and particulate emissions.

6. Which is more energy secure?

Biomass offers better energy security as it can be produced locally. Fossil fuels often require imports.

7. Which is better for the environment?

Biomass is generally better for the environment, especially when sustainably sourced. It reduces fossil carbon emissions and utilizes waste.

8. Which is easier to implement?

Fossil fuel systems are generally easier to implement due to mature infrastructure. Biomass systems are more complex but becoming easier.
