Question

energy use select one: a. has been declining in much of the world. b. is primarily from alternative energy sources. c. includes much use of biomass in developing countries. d. increased significantly in the richer countries.

Explanation:

• Option a: Global energy use, in general, has been increasing due to population growth and industrialization, so this is incorrect.
• Option b: Currently, most energy use is still from non - alternative sources like fossil fuels, so this is incorrect.
• Option c: In developing countries, biomass (like wood, agricultural waste) is widely used for energy, especially for cooking and heating in rural areas. This statement is correct.
• Option d: Richer countries have more stable or even slightly declining energy use per capita in some cases as they move towards more efficient systems, and the significant increase is more associated with developing countries' industrialization. So this is incorrect.

Answer:

c. includes much use of biomass in developing countries.
