A windmill uses wind power to create rotational energy for the use in mills, pumps and presses. In the Netherlands, where windmills became important for local economies, they were used to make boards, paint, oil, paper and bread.Continue Reading
The pumping of water was the earliest use of windmills. Depending on the strength of the wind, windmills could be used to pump water out of lakes and kept the land dry for agriculture. They could also pump water into fields for irrigation or to pump water for livestock. Windmills were also used to grind cereal grains, such as wheat or corn. Farmers would take their grains to a mill and grind their crops, leaving some of their crops as a payment for using the windmill.
Because the use of windmills are not dependent on energy costs, wind is free and abundant after all, they became popular in many countries for agricultural use. In modern times, small windmills have been used to aerate ponds in order to control the amount of algae produced in the water. They can also be used to generate electricity for areas that have no access to mains power. They are quieter and cleaner than fuel-burning electricity generators and cost less to upkeep, needing little more than to be oiled at regular intervals.Learn more about Physics
Nuclear energy provides power, heat and electricity by splitting atoms in a process called nuclear fission. The heat produced by fission creates steam that powers the turbines, thus generating electricity. Nuclear energy serves as a dependable source of power because it is not susceptible to inclement weather and climate conditions.Full Answer >
Hydro power is power generated using the energy of moving water. Hydro power, also known as water power, is mostly used to generate electricity, and it is the most inexpensive way to produce electricity, as of 2015.Full Answer >
Wind energy is a form of renewable energy produced through machines that use wind as their power source. Wind energy is only possible because of the sun.Full Answer >
Charles F. Brush of Cleveland, Ohio, was the first person to use wind to power energy sources in the winter of 1887. He used the wind turbine around his home to power cellular batteries that were in the basement of his mansion, creating the first recorded electrical use of wind power.Full Answer >
