A utility company plans to close its coal plant and replace its output entirely with a new offshore wind farm. Company analysts project that customer electricity bills will not rise, because the wind farm's projected per-megawatt-hour cost, once built, is lower than the coal plant's per-megawatt-hour cost.
Which of the following, if true, would most strengthen the analysts' projection?
- Coal prices have historically fluctuated more than the price of steel used in wind turbine construction.
- Other utilities that built offshore wind farms reported positive public reaction from environmentally conscious customers.
- The wind farm will create more permanent jobs in the region than the coal plant currently employs.
- The wind farm's output will be reliable enough that costly supplemental power will not be needed during low-wind periods.
- The wind farm is expected to have a longer operational lifespan than the coal plant before requiring major refurbishment.
