Question

list two advantage and disadvantage each for using wind as a source of energy ​

Answer 1

Answer:

Advantages of Wind Power

It's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Wind turbines don't produce atmospheric emissions that cause acid rain or greenhouse gasses.

The advantages of wind energy are more apparent than the disadvantages. The main advantages include an unlimited, free, renewable resource (the wind itself), economic value, maintenance cost, and placement of wind harvesting facilities. First and foremost, wind is an unlimited, free, renewable resource.

Answer 2

Advantages of Wind Energy

1. Wind Energy Is Renewable & Sustainable

The wind is both a renewable and sustainable resource. Unlike reserves of fossil fuels (such as coal, oil, and gas) it will never run out. This makes wind turbines a viable option in helping to meet our future energy demands.

2. It’s Good For The Environment

Wind energy is one of the most environmentally friendly energy sources known to man. This is based on the simple fact that wind turbines don’t create pollution whilst generating electricity.

3. It Reduces Fossil Fuel Consumption

Generating electricity from wind energy reduces the need for us to burn fossil fuels. This not only reduces carbon emissions but also helps to conserve dwindling supplies of the earth’s natural resources. As a result, reserves of fossil fuels like coal, oil, and natural gas will last much longer.

4. Wind Energy is Free

Unlike non-renewable energy sources, the wind is readily available and free for everyone to use. People use the wind each and every day for recreational purposes (such as sailing and windsurfing.) Utility companies use it to power wind turbines which are often installed as part of onshore or offshore wind farms.

Disadvantages of Wind Energy

1. The Wind Fluctuates

Wind energy has a similar drawback to solar energy in that it is not constant. Although the wind is sustainable and will never run out, wind speed does change. This can cause serious problems for the efficiency of a wind turbine. Utility companies invest a significant amount of time and money in researching which locations are suitable for wind power.

2. Wind Turbines Are Expensive

Although costs are reducing, wind turbines are still very expensive. First, an engineer must carry out a site survey. This may involve having to erect a research turbine to measure wind speeds over a period of time. If deemed adequate, a wind turbine then needs to be purchased, transported and installed. All of these processes contribute to the high cost of buying and installing wind turbines.

3. Wind Turbines Pose a Threat to Wildlife

We often hear that wind turbines pose a threat to wildlife – primarily birds and bats. However, researchers now believe that they pose less of a threat to wildlife than other manmade structures do.

4. Wind Turbines Are Noisy

One of the main disadvantages of wind turbines is the noise pollution they generate. You can sometimes hear them from hundreds of meters away depending on the wind direction. Combine multiple wind turbines with the right wind direction and the audible effects can be much greater. This issue is one of the biggest impacts of wind energy.
