WIND TURBINES A wind turbine is a machine that converts the kinetic energy in wind into mechanical energy If the mechanical energy is used directly by machinery such as a pump or grinding stones the machine is usually called a windmill Eggbeater turbines They have good efficiency but produce large torque ripple and cyclic
Factsheets and Statistics Wind Energy by the Numbers Wind energy produced worldwide 65 000 000 000 kWh per year enough power for 6 million homes Wind energy produced in the 16 000 000 000 kWh per year enough power
Wind Energy Environmentally friendly By Wesley Coopersmith Wind turbines additionally require the area around them to be clear of trees to maximize efficiency requiring an average of 50 acres per megawatt of capacity The GE MW turbine model needs at least 32 acres and the Vestas V90 model needs 78 acres for each
Power Generation from Coal Measuring and Reporting Efficiency Performance and CO 2 Emissions Coal is the biggest single source of energy for electricity production
Wind Turbine Efficiency This table is set up to accompany a blog posting about wind turbine efficiency because the tabular data would not display properly in the blog entry The table shown below consists of a range of common wind speeds in mph since that s the easiest number for Americans to grasp followed by their equivalent speeds in m/s
Here maximum L/D ratios are desired to maximize efficiency taking into account that the surface of a wind turbine will not be perfectly smooth during the whole life span of a windmill the airfoils should have good L over D values with rough surfaces too
Wind power in an open air stream is thus proportional to the third power of the wind speed the available power increases eightfold when the wind speed doubles Wind turbines for grid electric power therefore need to be especially efficient
Wind Energy and Wind Power Wind is a form of solar energy Winds are caused by the uneven heating of the atmosphere by the sun the irregularities of the earth s surface and rotation of the earth
