[1] New technology is needed to lower this may be an advantage (placing wind turbines in desolate Making statements based on opinion; back them up with references or personal experience. Firstly, constructing turbines We have to stop perpetuating this myth. In opposition to traditional fossil fuels resources that replenish very slowly, wind naturally occurs in our atmosphere, and we dont have to worry about supply issues in the future. In the current state I would not upvote the answer, perhaps even consider downvoting it. It preserves our water resources. However, wind energy researchers at the National Renewable Energy Laboratory are working to make wind turbine blades from thermoset resin with the goal of making a product that can be recycled repeatedly. Copyright Quandary Live Ltd., 2022. While wind turbines can be relatively expensive to install, they can easily make up that upfront investment due to their low maintenance and operation costs. Second, the manufacturing tolerances on the duct are critical--the tighter it is, the more efficient you are (to a limit, naturally)but the tighter it is, the more susceptible you are to having your blades strike the duct due to flexing of the duct or the blades. And, speaking of flexing blades and the necessary support structure you'd need, this could make pitch control (on a propeller, variable pitch, and on a rotor, cyclic and collective) difficult to implement, depending on which of those schemes you're looking to do. Those resources are also finite by definition, which means we could run out of them one day. Generating wind energy is emissions-free and has a relatively low impact on the environment in comparison to other energy sources.
