Renewable Energy : Different Types Of Renewable Energy Sources

Wind energy is clean and renewable. The wind is never going to stop blowing; therefore, there will always be enough to keep the turbines going. While some areas may have more wind than others, there is always wind. Wind turbines do not produce any pollution or waste, making them one of the cleanest energy sources on the planet. However, environmentalists are concerned that with the increase of wind turbines, bird populations with decrease because they are getting hit by the wind turbines and dying. Because of the huge poles in the ground, turbines can cause erosion and disrupt wildlife habitats. Wind turbines are also huge; at 30 meters (100 feet) above the ground, with large spinning blades, they can be a bit of an eyesore. They are also loud and have a deep buffeting sound. But the idea is that the large wind farms will be located in the middle of nowhere so they don’t cause an issue in suburban areas. Small wind turbines may be located in backyards to feed houses directly, but these would be so small that they wouldn’t bother any

While non-reusable natural resources diminish, scientists have created engineering marvels, such as the Hoover Dam and hybrid cars, to preserve what little resources remain. Windmills are one such creation that utilizes the ever powerful wind to power generators to supply electricity, and the old man is mesmerized by them: “those windmills were rather simple and lovely but

Wind turbines have evolved over the years to develop into what they are today. People have been using technology for years. For example, it was used for transportation sailboats as early

Topic Disclosure: Today the primary source of fuel for the generation of electricity are fossil fuels such as coal, natural gases, and petroleum.

Years before America was even a land mass, Persians struggled to find a way to obtain the grains and water they needed to survive. One day, the had the ingenious idea to build a horizontal windmill to grind their grains. The windmill was composed of four inner sails surrounded by walls to protect it from being destroyed in strong wind storms (“Persian Windmills”). The vertical windmill was also protected

Wind turbines are another common way to power things. They are usually made to power a city and many are needed for a lot of energy to be created at once. Wind turbines are made to be very tall because that the higher up you go, the windier it gets.

Power production can come from multitude of sources with different types of power plant facilities each with some sort of unique need; these sources include coal, natural gas, nuclear, wind, water also known as hydroelectric, solar, geothermal and biomass (U.S. Energy Information Administration). These energy sources are broken down into one of two categories, renewable or nonrenewable.

Wind powered machines are developed by the Babylonians. King Hammurabi of Babylon used wind powered scoops to irrigate Mesopotamia. Aside from irrigation and drainage, windmills were also used to ground grain, but maybe later on in history. This is just another advancement making work easier, yet more productive for mankind.

A. I’ll begin with Wind, which utilizes a Wind Turbine or more commonly known as windmill.

Dabiri of California Institute of Technology associated with aquatic bio forms. Wind turbines are the Colossus of the modern landscape and the blades can sweep up to a football field in diameter. Critics call this particular invention unsightly while the blades clobber unsuspecting birds. There is also an a efficiency problem while the blades become more powerful, but they’re size requires that they be spaced apart, this means they take up a lot of land. John Dabiri of Caltech also found a solution underwater and also built an experimental wind farm-(FLOWE). In which the location of turbine relative to each other takes advantage of air flow among them” Dabiri 1. “The turbine placement was determined by studying the wake vortices produced by schools of swimming fish” Dabiri 1. Dabiri’s 30 ft. tall wind turbine has blades that gather energy generated as wind flows through the wind farm. The blades take advantage of the wind’s behavior, for energy production, the way fish take advantage of water’s behavior for forward

The first known sources of energy were wood and coal. However, if you were to ask everyone to return to a time where the conveniences of travel such as cars did not exist it would be impossible. Even the Amish people don’t rely on wood and coal, relying instead on batteries, propane gas as well as wind plants (Kraybill). Wind power was used as early as 5000 B.C. where it helped speed boats along the Nile River. It was also used to power windmills in China in 200 B.C. New windmills were created to grind grain in Persia as well as the Middle East. Those same windmills were adapted to solely produce food, while the Dutch used wind power to expunge water out of lakes and marshes. It was later in the 19th century that windmills had been re purposed

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the

Since 400-500A.D, people used windmill energy in farms for grain grinding and water pumping. In 1888, the first wind turbine that generated electricity was discovered by Charles F.Brush in Ohio, USA. However, there are limitations on speed.

The main cost of wind energy is in the initial investment in the construction of a wind turbine; the upkeep cost is generally marginal and lower than one cent per kWhr. In general, wind power works by having air molecules move across the turbine blades transferring kinetic energy from the molecules to the turbine, causing it to turn. As it turns, the mechanical energy can be used to perform tasks such as grinding grain. More commonly, the turbine turns and utilizes a power generator to convert the mechanical energy to electrical energy.

In the second part, the performance of a real wind farm is studied. The wind
