A very Modern HIGH TECH wind turbine would be about 40-50% efficient in converting the winds kinetic energy into mechanical energy in the turbine. Then of course, the generator would be 90-98% efficient for a VERY efficient generator. The German physicist Albert Betz that the maximum efficiency of converting wind kinetic energy to mechanical energy is 59%. This number was derived from a lengthy and accurate physics calculation. This limitation is due to the 2nd Law of Thermodynamics. Think of it this way, if all the kinetic energy of the wind has to go to the wind turbine, then all the wind particles would loose all their kinetic energy and stop completely. The wind particles would just build up and stop more wind from flowing past if this was true.
A heat engine is similar but the efficiency increases as the temperature of the engine increases relative to its surroundings. That is why bigger engines (think power stations) are more efficient, because they can run at higher temperatures.
What else can I help you with?
What are wind turbines made?
Wind energy is made by spinning turbines. The wind spins the wind turbines and they generate energy.
What do wind turbines convert the winds energy into a rotational energy called?
Wind turbines convert the energy of the wind into rotational energy known as mechanical energy.
Is wind electrical energy?
Wind is not electrical energy itself, but it can be harnessed to create electrical energy through technologies like wind turbines. Wind turbines use the kinetic energy of the wind to spin turbines, which then generate electricity through a generator.
Is wind energy created by wind tubines?
Yes, wind energy is created by wind turbines. Wind turbines convert the kinetic energy of the wind into electrical energy by spinning a generator. This renewable energy source is harnessed to generate electricity for various applications.
How reliable is wind turbines?
wind turbines are very reliable in production of wind energy which in turn helps in the production of electrical energy
How do you access wind energy?
Wind energy can be accessed by installing wind turbines in locations with strong and consistent winds. These turbines convert the kinetic energy of the wind into electrical power. Wind farms are often built in open, elevated areas to maximize energy production.
How do Wind turbines capture wind?
Wind turbines have blades that rotate when the wind blows, converting the kinetic energy of the wind into mechanical energy. This mechanical energy is then converted into electricity by a generator inside the turbine. The turbine's orientation and design help to maximize the capture of wind energy.
Do wind turbines use renewable sources of energy?
yes wind is a renewable source of energy and that is what turbines use
What type of energy enables turbines to move?
turbines are moved by wind energy
How much of our energy comes from wind energy source?
Actually, most of our energy comes from wind energy sources, like wind turbines. Wind turbines are used all around the world.
Which one of these is a renewable energy wind turbines coal oil or gas?
Wind turbines.
What are some types of wind energy?
Wind turbines
