Electricity is energy transported by the motion of electrons Faraday Effect: Faraday Effect Faraday Effect Basic Concepts Voltage – V – Potential to Move Charge (volts) Current – I – Charge Movement (amperes or amps) Resistance – R – V = IxR (R in =ohms) Power – P = IxV = I 2 xR (watts) KidWind Project | www.kidwind.org How Does a Generator Work?: How Does a Generator Work? KidWind Project | www.kidwind.org Where do we get our electricity?: Where do we get our electricity? What is a Fossil Fuel???: What is a Fossil Fuel??? What is “Renewable Energy?”: What is “Renewable Energy?” Types of Electricity Generating Windmills: Types of Electricity Generating Windmills Small ( 10 kW) Homes Farms Remote Applications (e.g. water pumping, telecom sites, icemaking) Large (250 kW - 2+MW) Central Station Wind Farms Distributed Power Intermediate (1 0-250 kW) Village Power Hybrid Systems Distributed Power What is Wind Energy ?? : What is Wind Energy ?? The windmill is a device in which the energy of the wind is used to rotate a set of blades, and the rational energy of the blades is used to do some work. Parts of a Wind Turbine : Parts of a Wind Turbine Wind Turbine Perspective: Wind Turbine Perspective Nacelle 56 tons Tower 3 sections Workers Blade 112’ long Large Wind Turbines: Large Wind Turbines 450’ base to blade Each blade 112’ Span greater than 747 163+ tons total Foundation 20+ feet deep Rated at 1.5 – 5 megawatt Supply at least 350 homes PowerPoint Presentation: Yawing – Facing the Wind Active Yaw (all medium & large turbines produced today, & some small turbines from Europe) Anemometer on nacelle tells controller which way to point rotor into the wind Yaw drive turns gears to point rotor into wind Passive Yaw (Most small turbines) Wind forces alone direct rotor Tail vanes Downwind turbines Carnage!: Carnage! Environmental Impact Assessment: Environmental Impact Assessment Advantages: Advantages Wind Energy is Free, and the power it generates has been harnessed for centuries. Wind is a completely renewable resource because it is something that occurs naturally, once the means are there; technologically and practically, it can be harnessed constantly without destructive effects (emissions and use of resources) to our abused planet. Generation and maintenance costs for turbines have decreased significantly in recent years. Wind power is well suited to rural areas. Wind Power does not use water. Disadvantages: Disadvantages There are many obstacles to optimal use of Wind Power Transmission How to get energy from point A to point B Technology Means storage and containment of power must be developed Weather- Wind power is highly subjective not only to location but also to climate, time of year, and currents/weather patterns. It cannot be harnessed at places where wind does not blow regularly. Winds should be at least at 15km/hr For many problems new tower designs provide an answer Noise and view disruption become an issue with communities near wind farms. Endangered birds can be killed by flying too close to wind turbines PowerPoint Presentation: Thank You You do not have the permission to view this presentation.
