Question

9. (04.05 mc) compare the costs and benefits of biomass energy with coal, another carbon-based resource. (2 points) both biomass and coal energies are expensive, but they do not release greenhouse gases. both biomass and coal energies are renewable, and they help protect habitats. both biomass and coal energies are inexpensive, but they release greenhouse gases. both biomass and coal energies are nonrenewable, and they do not help protect habitats.

Answer 1

Biomass has the approximate chemical formula CHO. It is similar to coal with an oxygen atom added.

The oxygen reduces the energy of biomass compared to coal, because the carbon is “half burned” and that energy is not available.

What are the cost and benefits of biomass energy?

Is less expensive than fossil fuels.

While fossil fuel production requires a heavy outlay of capital, such as oil drills, gas pipelines and fuel collection, biomass technology is much cheaper.

Manufacturers and producers are able to generate higher profits from a lower output.

What is biomass a better alternative to coal?

Supporters identify biomass as an improvement over coal, touting benefits that include significant reductions in the emissions of sulfur dioxide, nitrogen oxides, and mercury.

Biomass releases approximately the same amount of particulate matter as coal and fifty percent more carbon monoxide and carbon dioxide.
