How tall is a modern wind turbine and how can it possibly generate power from the wind? This course gives an overview of key aspects in wind energy engineering. Whether you are looking for general insight in this green technology or your ambition is to pursue a career in wind energy engineering, 'Wind Energy' is an excellent starting point.
Experts located in the wind pioneering country of Denmark will take you on a tour through the most fundamental disciplines of wind energy research such as wind measurements and resource assessment, aerodynamics, wind turbine technology, structural mechanics, materials, financial and electrical systems.
You will gain a rational understanding of wind energy engineering and, through hands-on exercises, you will learn to perform wind energy calculations based on simple models. Working with the different course disciplines will give you a taste of what wind energy engineering is all about. This allows you to identify the most interesting or relevant aspects of wind energy engineering to be pursued in your future studies or in your professional career.

Frequently Asked Questions
When will I have access to the lectures and assignments?
Once you enroll for a Certificate, you’ll have access to all videos, quizzes, and programming assignments (if applicable). Peer review assignments can only be submitted and reviewed once your session has begun. If you choose to explore the course without purchasing, you may not be able to access certain assignments.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
What is the refund policy?
Is financial aid available?
Aerodynamics, how to find the right values of a and a'?
1.The formula for finding x = ({Omega}* R )/v_0
2.Solve[16 a^3 - 24 a^2 + a (9 - 3 x^2) - 1 + x^2 == 0, a]
3. a is in interval (0<a<1)
4. a' = (1 - 3 a)/(4 a - 1)
How many numbers after comma I should enter?
Coursera takes in unlimited about of numbers after comma, but we suggest you enter by approximation of 0.01, in cases where the answer is larger then 10000, the decimals are not necessary.
Economics: Having problems with negative values!
All answers are asked to be entered in absolute value.
Economics: I am having problems with calculating NPV!
You have included the present value of the decommissioning cost in the NPV calculation. We have not asked you to do that, so that is why answer is outside the range, but including these costs could also be done, so you are not entirely wrong.
