Advantages And Disadvantage Of Renewable Energy In India

If wind turbines are supposed to be good for the environment, what is to be said about their lethal effects on birds? How about the noise produced from the large turbines, whom many consider to be horrible eyesores that tarnish the countryside? Investing in these large, hideous structures is initially expensive, and while it may be true that there is an unlimited supply of wind, how is the resulting energy to be distributed? Undoubtedly, just as the advantages of wind power need to be taken into account, the disadvantages also need to be

With no doubt in mind the wind power plants are safer than most power providing resources. Providing clean energy for the human race and having a positive influence on climate change, the wind power industry is on a rise. With help from the government and with companies becoming more prominent on efficient energy, we could see an even bigger demand for wind power. Environmentally, the wind farms are one of the safest because of the low carbon and emission levels. Continuing are efforts to a safer future, the world is looking into wind farms more and more to help generate enough energy for the human

In a growing world, electricity production is becoming a problem due to coal fired electrical plants releasing millions of gallons of greenhouse gases, ecological problems with pollution in water, and health risks concerning workers and people living nearby. But with new technology and advances in renewable energy sources, wind energy is becoming one of the most popular energy sources for many states.

In the article “Nuclear Now,” Schwarts and Keiss point out some problems with wind power generation. First the “Whish, Whish” sound of the turning fan might bother the people living nearby. A relatively large area of land is needed for huge wind turbines. Also birds can be killed by the turbines. And, of course, there is the question of the cost. In “Wind Turbines Taking Toll on Birds of Prey,” for example USA Today reports that the number of birds killed by the

As the global supply of fossil fuels becomes steadily lower, need is growing for new energy sources that are beneficial to the environment and cost-effective. Wind power is one solution to this need. Wind turbines require significant investment, but are cost-efficient in the long term. If construction of turbines is sufficiently increased, the wind may be able to in the future provide a very major portion of global energy.

Secondly , windmills are really dangerous for the people living near them or working for windmills. Windmills make really loud noises which might cause health problems. There is a danger of people falling off of a windmill or a part falling down which can injure people. Also , the equipment used to build a windmill is really heavy.

The cause for this great rate of growth in wind power is contributed to tax incentives and state laws mandating renewable energy research. The nation 's total Wind power production is relatively low but some states like Iowa are investing in it heavily. Wind power produces 4.7 percent of the United States electrical energy and makes up over thirty percent of Iowa 's energy (American Wind Energy Association). Wind energy is gaining a lot of traction in northern states but almost does not exist in the southern states. When it comes to reliability wind energy is inferior to Hydropower. In order for a wind turbine to work wind speeds need to be around 8-55 mph and they are only efficient at wind speeds above 30 mph, anything below that minimal (National Wind Watch). This makes wind turbines less reliable because the wind can vary wildly throughout a day. Wind power also comes with some environmental impacts too. Wind Turbines kill tens of thousands of birds a year do to Turbines essentially being giant metal fans (Hosansky). Bats are especially affected because they rely on echolocation to see and giant moving blades confuse them into running into the blades.

Today, we have what is known as wind turbines. These large structures are used as a renewable and free energy source. The way a wind turbine works is very simple. As the wind blows, it moves the blades, which then turns a generator and makes electricity. These wind turbines are only a small source of energy because they work about 65 to 90 percent of the time. When many wind turbines are placed together in one area, it is known as a wind farm. The majority of wind farms are found in Texas and California. Wind farms are hoped to be spread all across the country to become a more prominent source of energy that is not only renewable, but also free.

“The potential of wind power is enormous – 20 times more than what the entire human population needs” (Energy Informative). The largest wind turbines can produce enough electricity to power 600 houses. Wind turbines can also be very space-efficient. They can be built on any existing farms, and those farmers are given a lot money as well. “About two billion people worldwide do not have electricity.

It has to be AT LEAST 8.7mph to turn a wind turbine. Another disadvantage about wind power is shadow flicker it is when the blades of the wind turbine cause a shadow as it turns. It would cause unwanted repetitive shadows over neighboring houses or buildings, it could be mistaken for power outages or even earthquakes. Finally, the sound of wind turbines they are not silent for the people that live near the wind farms would get unwanted noise in their houses content during the day and at night.

The second major negative effect is on wildlife. Although wind turbines are effect alternative energy that used to generated electricity, the hidden threat is a devastating wildlife such as bird and bat collision with the turbine. Bird and bat fly through space at a low pressure; therefore, make birds and bats lose balance in flight. A study analysis shows that 20-40 birds are exterminated by the wind turbines each year (Rosenbloom, 2006). The construction of wind turbines resulted in the diversity and population of the birds and bats decrease, it never come back again after start to use the wind turbine. Though wind turbine is not located directly on the food. Notwithstanding the impact of wind turbines is not a major problem, if neglected

H. Sterling Burnett's essay, "Wind Power Puffery," looks at the supposed beneficial alternative to burning fossil fuels: wind power. Many environmentalists view wind power as a resourceful way to reduce pollution and greenhouse gasses despite the costly methods. However, the negative aspects of wind farms override the ideal environmental benefits wind power can provide. Wind power is not only expensive, but it is limited, unsightly, and the turbines are killing native birds and bats. Contrary to the belief that wind power improves air pollution, the turbines work only when there is a certain range of wind. Too little wind produces no energy and too much wind causes a potential for the towers to blow down.

“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

The term, “non-renewable energy,” is at its most basic form, means that the sources of energy will eventually one day run out and not replenish itself. Non-renewable energy comes in many forms. For example: coal, crude oil and natural gas. These sources are categorized as fossil fuels, meaning that they were formed in the past due to natural processes from dead organisms. Non-renewable energy has been proven to be very beneficial to the US, however, many people argue the negatives are not worth the benefits.
