Energy Systems Engineering Technology ESET 222 Wind & Solar Energy Winter 2024 Professor: Arun Hor. Wind Power Fundamentals ESET 222: Wind & Solar Energy Wind Tech Click ESET 222: Wind & Solar Energy Wind Power Wind Tech Click ESET 222: Wind & Solar Energy Wind Energy & 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. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover. This wind flow, or motion energy, when "harvested" by modern wind turbines, can be used to generate electricity. A wind turbine is a device that converts kinetic energy from the wind into electrical power. A wind turbine used for charging batteries may be referred to as a wind charger. Wind energy is one of the fastest growing major sources of new electricity around the world. Today, there are over 486,790 wind turbines operating around the world in over 90 countries. click ESET 222: Wind & Solar Energy Wind Energy & Power Wind is caused by huge convection currents in the Earth's atmosphere, driven by heat energy from the Sun. This means as long as the sun shines, there will be wind. The earth's surface has both land and water. When the sun comes up, the air over the land heats up quicker than that over water. The heated air is lighter and it rises. The cooler air is denser and it falls and replaced the air over the land. In the night the reverse happens. Air over the water is warmer and rises, and is replaced by cooler air from land. ESET 222: Wind & Solar Energy Wind Energy & Power Wind is caused by huge convection currents in the Earth's atmosphere, driven by heat energy from the Sun. This means as long as the sun shines, there will be wind. Anywhere and each time there are differences in atmospheric (air) pressure, there will be winds, because air will move from the high pressure area to the low pressure area. It also means that winds may be even stronger where the difference in the air pressure is greater. A good example is how a tropical depression forms, where warm air over hot tropical waters rise, and high pressure cold air quickly rushing to fill the space. ESET 222: Wind & Solar Energy Wind Energy & Power o Wind power is good renewable, clean and free source of energy for power production o Reduce dependence on fossil fuels including imported oils o Reduce emission of greenhouse gas and other pollutant o One major concern is the noise – can be improved o Intermittency and variability of the wind ESET 222: Wind & Solar Energy Typical Cost A 10 kW wind turbine costs approximately $48,000 – 65,000 to install. The equipment cost is about $40,000 and the rest is shipping and installation. The purchase and installation of very small (
