April 13-19, 2014 is National Environmental Education Week, and throughout April, students, educators and others around the country are taking part in learning focused on how the STEM (science, technology, engineering and math) fields, specifically engineering, can be used to solve some of today’s biggest environmental problems, leading to sustainable solutions for a healthier planet and healthier people.

So, how is engineering helping to solve some of our biggest environmental challenges?

Biomimicry: Whale Fins and Wind Turbines

Many of the environmental problems that engineers are working to solve already have hints to solutions in the natural world. Using the complex sciences of fluid dynamics and biomechanics, researchers discovered that the bumps on the front edge of humpback whale fins (called tubercles) increase lift and reduce drag for maximum efficiency as the whales move through the water. Now, a company called WhalePower is applying this bumpy-edged design to wind turbines and fans to increase efficiency – researchers have found that adding tubercles to wind turbine blades increases efficiency by 20 percent.
