7/2/2017 Wind Energy: Advantages Wind Energy: Advantages  Hydro is currently the most used renewable  Wind energy conversion does not resource and incredibly efficient if sited produce greenhouse gas emission in correctly. Its reliability also surpasses the contrast with biomass wind energy due to stability of water flow  Wind energy can pay back the against wind energy spent for its manufacture  It is really hard to find a good location for a very soon, whilst harvesting biomass dam, so Hydro is not expanding todays. Wind corps often takes more energy than energy is catching up its high position, and it can be produced with it wouldn’t be long until it happen  Using wind turbine, can generate  Geo Thermal energy requires electricity ANYTIME unlike solar special location which is not many in the world whilst wind can be panels which only work at daytime  Nearly all countries have several found sufficiently, almost every windy areas, while few countries where  Investment return time can be have continually sunny regions.  Wind‐produced power costs nearly very higher than wind energy twice less per KWh than solar harnessing systems WIND ENERGY CONTROL BY MAJID FIROUZBAHRAMI 2 July 2017 17 WIND ENERGY CONTROL BY MAJID FIROUZBAHRAMI 2 July 2017 18 Wind Energy: Disadvantages Wind Energy: Disadvantages LAND USE WILD LIFE AND HABITAT VISUAL IMPACT PUBLIC HEALTH WIND ENERGY CONTROL BY MAJID FIROUZBAHRAMI 2 July 2017 19 WIND ENERGY CONTROL BY MAJID FIROUZBAHRAMI 2 July 2017 20 5

7/2/2017 Wind Energy: Future Wind Energy: Future  Main Drawbacks  IRAN  It is more expensive to produce wind-sourced electricity than other  Iran has this capacity to produce near to 40,000 MW Wind-produced electricity conventional sources, such as nuclear and thermal energy. which is about half of required energy in the country in a year.  Wind power is intermittent because winds are unpredictable and uncontrollable.

7/2/2017 Wind energy harnessing: VAWT HAWT: Structure and main parts  Advantages  No yaw mechanisms is needed  A VAWT can be located nearer the ground, making it easier to maintain the moving parts.  VAWTs have lower wind startup speeds  VAWTs can be installed when taller structures are prohibited  Disadvantages  Most VAWTs have an average decreased efficiency from a common HAWT due to the additional drag that they have as their blades rotate into the wind  Having rotors close to the ground where wind speeds are lower, VAWT does not take advantage of higher wind speeds  VAWT is not commonly deployed due to the serious disadvantages mentioned above, so is not familiar for investors and this has made it almost neglected over the last 50 years WIND ENERGY CONTROL BY MAJID FIROUZBAHRAMI 2 July 2017 29 WIND ENERGY CONTROL BY MAJID FIROUZBAHRAMI 2 July 2017 30 THANK YOU FOR TAKING YOUR TIME WIND ENERGY CONTROL BY: MAJID FIROUZBAHRAMI 8
