Question

ocean wave energy is a renewable energy source that uses the kinetic energy of the waves to produce electricity. which statement describes a disadvantage of ocean wave energy?
ocean wave energy devices must be able to withstand severe storms, resulting in high construction and maintenance costs.
ocean wave energy is relatively consistent and predictable as waves can be accurately forecast several days in advance.
ocean wave energy is an abundant and renewable energy resource as the waves are generated by the wind.
ocean wave energy reduces dependency on fossil fuels as wave energy consumes no fossil fuels during operation.

Explanation:

Ocean wave energy is a renewable energy source. The first option mentions that ocean wave energy reduces dependency on fossil fuels as it consumes no fossil fuels during operation. This is a clear advantage as it helps in moving towards a more sustainable energy future by decreasing reliance on non - renewable fossil fuels.
The second option about it being an abundant and renewable resource (generated by wind) is more of a general characteristic rather than a direct advantage in terms of energy consumption and fuel dependency.
The third option about being relatively consistent and predictable is a characteristic but not as directly related to the advantage of reducing fossil fuel dependency.
The fourth option about the devices' requirements is a drawback or a design consideration rather than an advantage.

Answer:

Ocean wave energy reduces dependency on fossil fuels as wave energy consumes no fossil fuels during operation.
