Re-order Paragraphs
Arrange the sentences into the correct order.
Put the sentences in the correct order:
- Consequently, modern wind farms now generate substantially more electricity per turbine than those built only a few decades ago.
- This redesign allowed a single blade to extract noticeably more energy from the same wind speed than its flat predecessor.
- Engineers responded by tapering and twisting the blade along its length, so that each section meets the airflow at a more efficient angle.
- Early turbine blades were flat and rectangular, which made them simple to manufacture but poor at capturing energy from wind approaching at an angle.
- The purpose of a wind turbine blade is to convert the kinetic energy of moving air into rotational force with as little loss as possible.
