Which disadvantage of wind power?

A. It can be used anywhere
B. It creates pollution
C. It can harm wildlife
D. It is not efficient

C. It can harm wildlife

The disadvantage of wind power is:

C. It can harm wildlife

The correct answer is C. It can harm wildlife.

To arrive at the answer yourself, you can consider the following information:

A. It can be used anywhere: This is actually an advantage of wind power, as it is a renewable energy source that can be harnessed in many different locations. Therefore, it is not a disadvantage.

B. It creates pollution: Wind power is considered a clean source of energy because it doesn't emit greenhouse gases or other pollutants during operation. This makes it an environmentally friendly option, so it is also not a disadvantage.

C. It can harm wildlife: This is a valid disadvantage of wind power. Wind turbines can pose a threat to birds and bats, especially if they are not properly sited or have poor design features. Collisions with turbine blades or disruption to flight paths can result in injury or death to certain species. However, it's important to note that renewable energy technologies are constantly evolving and efforts are being made to minimize the harm to wildlife.

D. It is not efficient: Wind power has improved in terms of efficiency over the years, and modern wind turbines are capable of converting a significant portion of wind energy into electricity. While it may not be as efficient as some other forms of power generation, such as natural gas or nuclear power, it is still a viable and increasingly cost-effective option. Therefore, this is not the correct answer either.

In conclusion, the correct answer is C. It can harm wildlife.
