Question

What are the disadvantages of using wind and solar energy?

Answer 1

Answer: The Wind Fluctuates. Wind energy has a similar drawback to solar energy in that it is not constant. Wind Turbines Are Expensive. Although costs are reducing, wind turbines are still very expensive.

Answer 2

1: The Wind Fluctuates, wind speed does change. This can cause serious problems for the efficiency of a wind turbine.
2: Wind Turbines Are Expensive, wind turbines are still very expensive. If deemed adequate, a wind turbine then needs to be purchased, transported and installed. All of these processes contribute to the high cost of buying and installing wind turbines.
3: Wind Turbines Pose a Threat to Wildlife, wind turbines still contribute to mortality rates among bird and bat populations.
4: Wind Turbines Are Noisy, You can sometimes hear them from hundreds of meters away depending on the wind direction. Combine multiple wind turbines with the right wind direction and the audible effects can be much greater.
