Created with Fabric.js 1.4.5 MECHANICS Should Wilmette Junior High invest in awind turbine? Lets look at the facts: Loss of territories - productive land,industries and raw resources The Deutsche Mark lost 75% of it's value during WW1. It was after the war,however, when hyperinflationbegan ENVIORMENT right wing Sparticist Uprising Nov 1923 - 200,000,000,000 D Marks Sept 1922 - 163 D Marks WIND POWER 48% of ironore lost 26% of coalresources lost def; energy extracted from wind using wind turbines to produce mechanical power VS Wind spins blades,blades turn shaftconnected to generatorthat makes electricity. horizontal axis vertical axis blades facein direction of wind,spinning up wind egg beater like style, don't have to be facing in direction of wind PARTS OF A WIND TURBINE PARTS OF A WIND TURBINE BLADES- wind creates pockets of pressure causing blades to turnNACELLE- holds generator & gearbox through series of gearsTOWER- steel cylinder about 150-200ft tall, 10ft in diameterBASE- made of concrete reinforced with multiple steel bars RENEWABLE RESOURCE a source that exists freely in nature, such as WIND ENVIORMENTAL IMPACTS: -only 1kilometer disturbed permegawatt of energy used-bird and bats can be killed byair pressure changes-noises the wind turbine createsvary between different designs wind turbines negatively impact wildlife MYTH: FACT: new technology is being designed for wind turbines free of animal harm BEST LOCATIONS: -coastines-places with strong wind-not insulated by trees $350,000 cost to purchase and install a 100kw wind turbine 4% wind power as a percentage of all energy production in the USA 61,108mW current USA wind power capacity 59% maximum windpower efficiency STATS CONS PROS -renewable resource-no water impacts-no climate changeimpacts-free of repairs onceinstalled-once installed, no other costs -only works in certainareas of land-community disturbance-maximum efficiency of59%-expensive for initialinstalment THE FINAL VERDICT Wilmette Junior High School should invest is a wind turbine as a secondary energy source. For one, wind turbines are very environmentallyfriendly, because the source is renewable and doesn't pollute. In addition, wind turbines are a wise choice economically because it only costs $350,000 for eternity, unlike fossil fuels where the substance must be repurchased. For these reasons, an investment in a wind turbine would be a wise choicefor Wilmette Junior HIgh School.
