Wind Energy

• 43.96% coal as source of energy in the Philippines.
• at least 7m/s wind speed.
• we can harness wind energy through a wind turbines that transforms the kinetic energy of air currents into electrical energy.
• 500 to 900 A.D. - Persians use windmills to crush grains
• 1800s - invention of icon halladay windmill
• 1900s - world's first offshore wind farm begins operation
• Kinds of Turbine

  • Vertical Axis Wind Turbine (VAWT)
  • Horizontal Axis Wind Turbine (HAWT)
• Horizontal axis wind turbine

  • modern wind turbine
  • pros: blades are expandable
• Parts of a Wind Turbine

  • rotor
  • gear box system
  • generator
• rotor

  • 3 blades and the bushing that joins them together.
  • Function to capture the forest of the wind and convert it into mechanical rotational energy
• Gear box system

  • connected to the engine by means of a shaft.
  • Function is to increase the rotational speed from 30 revolution per minute (rpm) to 1500 rpm
• Generator

  • this element is responsible for converting mechanical energy of rotation into electrical energy.
• Power Curve - - is a powerful tool to estimate the power extraction process as it qualifies the relation between incoming wind and power output of a wind turbine.
• only capable to produce 2 megawatts
• At 25 velocity of wind, the turbines will shut off (reason: dangerous)
• Department of Energy (DOE)

  • Is mandated by RA 7638 (department of energy act of 1992)
  • to prepare, integrate, coordinate, supervise and control all plans, programs, projects and activities of the government relative to energy exploration, development, utilization, distribution and conservation.
• Energy Regulation Commission (ERC)

  • Is mandated to promote competition, encourage market development, ensure customer choice and penalize abuse of market power in the electricity industry.
• Republic Act 9513

  • renewable energy act of 2008
  • The policy that will accelerate the development of the renewable energy sector in the country.
• Project financing is also a concern in advancing not only the wind energy sector but the whole renewable energy industry.
