1 Wind Power and Wind Powered Turbines Renewable Energy Resources Wind power

2 Objectives: To design and construct a wind turbine to see who can create the most power (volts actually). Demonstrate understanding of the required parts of a wind turbine. Utilize mechanical and conceptual skills through construction and operation of a model wind turbine. Wind power

3 First sailing boats dating back to 300 BC. In the 19th century, wind mills were constructed all along the Norwegian coast to grind grain. The international oil crisis at the beginning of the 1970s helped spur the development of modern wind generators for the production of electricity. Wind energy remains one of the most eco-friendly energy sources for large- scale energy production.

4 Does wind have energy? If so, what type of energy? What does wind need to be doing to utilize its energy? Wind power

5 Reminder: PotentialKinetic Gravitational Potential – energy due to the position of an object. Chemical Potential – energy present within the chemical bonds of a substance. Elastic potential – energy of a stretched or compressed object. Nuclear potential – energy of particles inside an atomic nucleus. Radiant solar energy – the motion of EMR Sound energy – the motion of sound waves Electrical energy – the motion of flowing electrons Thermal energy – the motion of particles

7 Wind power Facts: Wind turbines produce electricity by converting the kinetic energy of the wind into electrical power. Wind power is renewable and has zero emissions. Wind power is the world’s fastest growing source of energy, and is most widely used in the US, Germany, China, Spain and India. Statkraft.com

8 Wind power How big are they? Statkraft.com Each turbine weighs just over 260 tonnes in total

9 Wind power The rotor blades on a wind turbine transfer the power of the wind via a drive shaft and gear box to a generator in the nacelle.

10 Wind power What is a volt? – When a charge is at high voltage, it means it has lots of potential energy. 1.5 V 9 V 12 V

11 Wind power What is an ampere (amp)? – Current is electricity in motion. It measures the amount of electrons that can flow through a material like a conductor. Electrical current is measured in amperes or "amps".

12 Wind power What is a watt? – The watt is a unit of power. – The power (P) it takes to send current (I) through a wire is given by: P = V I

13 Wind power What is a watt? – The watt is a unit of power. – The power (P) it takes to send current (I) through a wire is given by: P = V I

14 The Smola Wind Farm comprises 68 wind turbines with a combined capacity of 150 MW. 150 MW = 150,000,000 W Statkraft.com

15 The Smola Wind Farm comprises 68 wind turbines with a combined capacity of 150 MW. The annual production is about 450 GWh, corresponding to the average electricity consumption of Norwegian households. Statkraft.com 450 GWh = 450,000,000,000 Wh

16 The Smola Wind Farm comprises 68 wind turbines with a combined capacity of 150 MW. The annual production is about 450 GWh, corresponding to the average electricity consumption of Norwegian households. The wind turbines in each row stand meters apart. Cables have been laid in the roads from the turbines to a centrally located transformer. Statkraft.com

20 Wind Turbine We will compare designs by measuring volts.

21 Wind power Challenge: Design the best wind turbine to maximize amount of volts produced?

22 Wind power Challenge: Step 1: Design – Things to consider: a. Fin size (small to larger) b. Fin shape c. Organization of fins d. Fin material

23 Wind power Challenge: Step 2: Build
