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 mphOne medium-sized river with slow currentsRainy conditions most of the yearNo coal or oil depositsBased on this information, which energy source would be most economical for the community to use?A.Fossil fuelsB.SolarC.HydroelectricD.Nuclear
Solution
Based on the information provided, the most economical energy source for the community would be C. Hydroelectric. This is because the community has a medium-sized river with slow currents, which can be harnessed to generate hydroelectric power. The other options are less feasible: Fossil fuels are not available locally, the average wind speed is too low for wind power, and the rainy conditions most of the year would limit the effectiveness of solar power. Nuclear power could be an option, but it is typically more expensive and complex to implement than hydroelectric power.
