Question

a community needs more electrical energy. the community is located in an area with the following characteristics: • average wind speed of 0 to 5 mph • few rivers or streams • rainy conditions most of the year • large surplus of waste corn based on this information, which energy source would be most economical for the community to use?
a. biomass
b. solar
c. wind
d. hydroelectric

Explanation:

• For option B (Solar): The community has rainy conditions most of the year, so solar energy (which relies on sunlight) is not ideal as there would be limited sunlight.
• For option C (Wind): The average wind speed is 0 - 5 mph, which is too low for effective wind energy generation (wind turbines typically need higher wind speeds).
• For option D (Hydroelectric): The community has few rivers or streams, so there is not enough water flow to generate hydroelectric power economically.
• For option A (Biomass): The community has a large surplus of waste corn. Biomass energy can be generated from organic materials like corn waste, so this is a viable and economical option given the available resources.

Answer:

A. Biomass
