what factors make wind energy imperfect as an energy source?

This form of energy generation has become increasingly popular in recent years. The amount of wind electricity generation has grown significantly in the past 30 years. Electricity generation with wind. The nation's wind supply is abundant and inexhaustible. When the wind blows past a wind turbine, its blades capture the wind’s kinetic energy and rotate, turning it into mechanical energy. Estimating your wind resource and checking your local permitting and zoning requirements are key factors to consider in order to pursue this option. In fact the main energy losses with wind power comes from the energy used to make the turbines in the first place. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling. Wind: Harnessing the wind as a source of energy started more than 7,000 years ago. Remind them that no idea or suggestion is "silly." Using coal, over 60% of the energy in the coal is lost as waste heat. However, if costs over the lifespan of energy projects are taken into account, wind and utility-scale solar can be the least expensive energy generating sources, according to asset management company Lazard. Harnessing the wind is one of the cleanest, most sustainable ways to generate electricity. Wind is an emissions-free source of energy. Wind is a domestic source of energy. Brainstorming: Have students engage in open discussion to think of how wind could be used as an energy source. Wind is actually a form of solar energy. Wind is a renewable energy source. wind turbine: A machine that converts the moving energy of wind into mechanical and/or electrical energy. It's sustainable. Over the past 10 years, U.S. wind power capacity has grown 15% per year, and wind is now the largest source of renewable power in the United States. Multiple studies have concluded that wind has an energy return on energy invested of around 20. And since the wind is free, operational costs are nearly zero once a turbine is erected. This rotation turns an internal shaft connected to a gearbox, which increases the speed of rotation by a factor of 100. It offers much the same benefits that many other alternative fuel sources do in that it makes use of a renewable source and generates no waste. Wind is a clean source of renewable energy that produces no air or water pollution. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Small wind systems can reduce your energy-costs by as much as 90 percent, but they do require careful planning. Assessment Pre-Activity Assessment.
