Wind turbines are designed to exploit the wind energy that exists at a location. Aerodynamic modelling is used to determine the optimum tower height, control systems, number of blades and blade shape. Wind turbines convert wind energy to electricity for distribution. Conventional horizontal axis turbi...
producing (produce) electricity, such as wind turbines and solar panels, can only provide power on the days 5. when wind blows or the sun shines. Electricd batteries 6. used (use) to store energy are expensive and can also be polluting. Finnish scientists came up with a simple solution ...
