Recommended: Pros and cons of traditional sources of energy
The energy produced and created by using the kinetic energy which comes from the wind naturally is known as the wind power. Wind power is the technology to catch the energy gained with movement, kinetic energy, and change this energy into electrical power which is useful in many places, such as households throughout the nation. Wind power can be produced by using a device called wind electric turbine. Several huge blades, about 30 feet long, are placed on each wind turbine. While wind passes through the blades, the wind with kinetic energy makes the blades to turn. The movement of blades makes a shaft inside the turbine to be in motion as well with the same velocity of the blades. This work turns the kinetic energy into rotational energy which will be stored into a generator located at the bottom of the turbine. After the rotational energy is kept in the generator, this energy is changed into electrical energy. Finally, the electrical energy is removed into the electrical plant for storage by the power lines until the communities are in need of energy.
Referring the process, systems, structures, and equipment that help with conversion between kinetic energy and the pressure energy of flowing water into electrical energy is known as hydroelectric power. Hydroelectric skill became a leading force of development in the living standard during the electrical age. During the Industrial Revolution, hydro mechanical technology was developed based on simple water wheels from ancient times. The method, conversion of flowing water to electricity, is known as very environmental process because no waste is created during energy generation. Many hydroelectric power plants depend on the same similar basic rule as a historical water wheel. Howe...

...tion or loss of fish habitat, and inundation of wildlife habitat and land in some cases. There could be changes in stream water quality and reservoir in some cases as well.
Although both wind power and hydroelectric power have some disadvantages, I believe wind power is more useful than hydroelectric power because wind power will not produce any pollutants while hydroelectric power produces few minimal pollution. Also, hydroelectric power plant needs high investment costs, so this device cannot be built by the developing countries. On the other hand, the cost of wind power is decreasing because of better generation techniques and technology improvements, so the wind power will become increasingly feasible as a main source of mechanical power and electricity. I believe the device that can be built by everyone is more likely to reduce global warming problems faster.
Its most known process of generating electricity would be movement of air through wind turbines. Wind power has two parts, mechanical and electrical systems. Mechanical systems are low speed and are used for mechanical tasks such as pumping water or grinding grain. Electrical systems are high speed and are used to generate electricity to power homes or schools. Many people feel that wind farms full of turbines, are aesthetically unpleasing, but wind power is a clean energy source and does not generate greenhouse gas emissions. It is a very abundant resource throughout the United States. Wind power is simple, relatively cheap, and low maintenance (Sambu). Wind power is again, free and very abundant so no matter how much we use now, we will still obtain enough in the
When it floods sediments can affect the land by losing nutrients in the soil and it can also affect the clarity of
Besides the long known history, the ways electricity is generated through wind turbines are truly simple, too. “Turbines catch the wind's energy using blades which are mounted on a shaft. The shaft is connected, normally via a gearbox, to a generator which produces electricity. The blades and shaft are connected to the
One of the main types of renewable energy that we have used the most is the wind energy. Wind energy is the energy produced from the power of the wind. Throughout the 20th century, wind energy was used by sailboats as a fuel to move the boat in different directions. In the past, this was the most frequent way for shipment of goods. Sailboats were also used as a method of transportation. Also, wind energy is used to power wind turbines and convert the wind energy into electricity. Without the wind energy, the production of electricity and the shipment of goods would have been very difficult and perhaps life on earth might have perished. Thus, the efficient ways of using the renewable energy such as wind energy has played an enormous role to our existence and it has made engineers more successful at harnessing
Wind turbines can be very useful in bringing energy into your home. They are especially useful when solar panels aren't working. They take the wind speed from oceans, lakes, dugouts, or rivers and turn it into energy. To use the wind turbines most efficiently you should set up a wind power system.
The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
Hydro power is one of many examples of alternative energy source. Hydro power is producing energy by moving
One efficient way to acquire energy is Hydropower. Hydropower is power derived from the energy of falling water or fast running water. This energy converter is harmless to the environment. Other ways will affect the atmosphere and the environment in a negative way. The most common device for hydropower is a dam. It relies on the water cycle. This is one of the oldest sources of energy.
Next, hydro-electricity is electricity produced by moving water, flowing past a turbine connected to a generator (“Hydropower”). According to Nationalgeographic.c...
For electricity to be generated there is a need for a source of energy. Some of these sources will include Wind, liquid water forced to move at high velocity or steam projected at high pressure. The energy harnessed from these sources is used to run large turbine devices which in turn run attached generators that produce electricity that is the extracted and distributed. These sources produce mechanical and kinetic energy that is extracted by massive turbine devices that have blades spinning at great speeds. These blades are connected to the turbine shaft.
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
Wind turbines are a great source of energy around the world. Wind turbines produce wind energy that can be used to power our homes. Wind turbines convert kinetic energy into mechanical power. Then this mechanical power gets generated into electricity. Wind turbines make energy by the wind turning the large blades, which spin a shaft that is connected to the large blades, which then operates the generator making electricity.
The Wind Turbine is a device that converts the kinetic energy of the wind into kinetic energy of turbines. The turbines turn to generate electricity but they work only when there is wind. The efficiency is 30-40%. The environmental impacts are needs many large turbines to generate electricity which can be noisy and unsightly. Turbines may endanger birds and bats.
Hydroelectricity is a known renewable energy resource that provides substantial benefits for our wealth, our health, and for our global economy. There are five types of renewable energy we can use on a daily basis throughout our lives, but the most widely installed form of renewable energy is hydroelectricity. Hydroelectricity is electricity created by converting the kinetic energy of flowing water. Best thing about this source of energy is that it’s timeless and renewable, which means it will never run out, however we had to figure ways to store this energy. In order for them to harness this energy for other people, they had to build generators that convert all the potential energy of rapid moving water into electrical energy.

Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
