Question

a community needs more electrical energy. the community is area with the following characteristics:

• average wind speed of 0 to 5 mph
• one small river with slow currents
• dry, sunny conditions most of the year
• no coal or oil deposits

based on this information, which alternative energy source sho community consider investing in?
a. wind energy
b. biopower
c. hydropower
d solar ener

Explanation:

• Wind energy (A): The average wind speed is \(0 - 5\) mph. Wind turbines typically need a minimum wind speed of around \(9 - 10\) mph to operate efficiently. So wind energy is not a good option.
• Biopower (B): There is no mention of biomass - related resources (such as agricultural waste, dedicated energy crops) in the given characteristics. So biopower is not indicated.
• Hydropower (C): The river has slow currents. Hydropower plants, especially large - scale ones, need significant water flow (fast - moving water) to generate electricity effectively. A small river with slow currents is not ideal for hydropower.
• Solar energy (D): The area has dry, sunny conditions most of the year. Solar panels can convert sunlight into electricity, and these sunny conditions are favorable for solar energy generation.

Answer:

D. Solar energy
