Can higher wind turbines generate more power with a smaller blade length?

The higher altitude allows for greater wind velocity, which can potentially facilitate the generation of the same amount of power with a smaller blade length. This study proposes the conduction of research on the technological and economic viability of higher WTs with smaller blade lengths.

Are wind turbines dangerous?

While wind energy is a clean and renewable power source, wind turbines can pose a risk to flying wildlife. Birds and bats may collide with turbine blades, resulting in injury or death. Studies suggest that wind farms located in migratory routes or near habitats with high bird and bat populations are more likely to cause fatalities.

What can go wrong with a wind turbine?

Wind turbines are complex pieces of machinery and there’s a lot that can go wrong with them. The turbine blades, generators and gearboxes can often fail - meaning that regular maintenance is very important. However, due to the remote locations of wind farms it can be difficult to carry out maintenance duties.

How long do wind turbine blades last?

The Institute of Environmental Management and Assessment (IEMA) states that the average wind farm will pay back the energy that was used in its manufacture within 3-5 months of operation. Do old wind turbine blades end up in landfill, or can they be recycled?

Could large-scale wind power cause more environmental impact?

This research was funded by the Fund for Innovative Climate and Energy Research. Researchers have determined that large-scale wind power would require more land and cause more environmental impact than previously thought.

Can wind turbine blades be recycled?

While it’s partially true that some can’t be recycled, manufacturers and operators are going to great lengths to ensure they are ultimately as sustainable as possible; finding ways to either recycle, reuse or rebuild them using recyclable materials in the future. What are wind turbine blades made of?
