Question 1

Correct Answer:

Verified

Industrialized countries have an established infrastructure and mature industries. Increases in energy consumption due to population growth or expansion are balanced by efforts to conserve and to become more efficient. Some developing countries are just now realizing their industrial capabilities and their demands for energy increase linearly with their development.

Biomass is more efficient in providing energy than biofuels. Biomass uses a greater fraction of the crop than biofuels, and biomass produces more energy per acre of crop than biofuels. Yet, biofuels continue to be studied more extensively than biomass. Why does research continue to focus on biofuel optimization?

Question 2

Correct Answer:

Verified

Refer to the graph below showing world energy consumption by fuel type. Some analysts have projected that we will reach "peak oil" in 2015; that is, oil production will reach a global maximum in 2015 and further increases annual petroleum supplies will be impossible. If this is true, how will it impact world energy consumption?

Question 3

Correct Answer:

Verified

Oil consumption will reach a maximum in 2015 and will either remain flat or decline. The other forms of energy must increase to meet demands. Coal will likely increase the most and nuclear will increase the least. Hopefully, "peak oil" will provide impetus to stimulate the research and growth of renewable energy sources.
