Burning biomass to produce electricity avoids many of the problems associated with gathering, refining, transporting, and burning fossil fuels. Yet the use of biomass as fuel is not without its own set of problems. What challenges might arise from a large-scale conversion to biomass energy? How do these challenges compare with those encountered with fossil fuels? Which set of challenges do you think is more likely to be overcome? Does one energy source have more benefits and fewer costs than the others? Explain.
Select one of these alternative energy sources and compare it to a fossil fuel of your choice. Focus on the positive and negative aspects of each. Which do you feel is better choice? Why?
What is your opinion/stance on biofuels as an alternative energy source?

- To generate biogas the required biomass resources must be on wet form, else biogas will not produce. How do you disagree or agree with this statement? Justify your answerarrow_forwardProvide one way you can reduce carbon emissions.arrow_forwardFossil fuels contain the carbon and energy of organisms that have been dead for a very long time—in some cases, for millions of years. Biofuels, in contrast, are fuels that are made from recently living organisms, usually plants. Since biofuels come from living plants, the carbon dioxide released from burning biofuels is part of the modern-day carbon cycle. All of the following statements are true statements about biofuels. Select which statements are negatives of using biofuels as a primary source of energy. Check all that apply. A. With limited agricultural land, growing crops for biofuel might compete with growing crops for food. B. The carbon dioxide released into the atmosphere is carbon dioxide that was recently taken out of the atmosphere, so it does not overload the carbon cycle. C. Large-scale agriculture needed to grow plants for large amounts of biofuel may be damaging to the environment in other ways.arrow_forward

If this manufacturer were to reduce their annual carbon emissions by 1 tonne it would cost (marginal cost) them $5 dollars, by 2 tonnes it would cost them $10, by 3 tonnes it would cost them $15 and 4 tonnes would cost them $20.
