What Are Considered To Be The Advantages Of Wind Energy?
The welfare of the planet has been a hot topic of conversation over the last few years. Environmental awareness is causing significant changes to our lifestyles. Taking action for our planet is high on the agenda of many of the Earths inhabitants. There is good reason; we are very quickly running out of time to make a change.
There is a big change towards a more ethical and eco-friendly lifestyle. Part of this involves looking at the fuel we use and consume. We also need to consider alternative, less harmful methods of generating energy. Helping to reduce the carbon footprint of human beings is another essential. One area which is particularly growing is that of wind energy. It is easy to see why; wind is plentiful and free. This also offers an alternative to traditional fossil fuels and resources.
What Is Wind Energy?
As the name suggests, wind energy involves harnessing the power of the wind. At its core, wind is simply moving air. The sun heating the land results in the movement of air – the force we have named ‘wind’. This is a high speed movement. Over time, the speed means that the resulting product contains kinetic energy. This energy can then be used to our advantage.
Why Do We Need Wind Energy?
In times gone by, generating electricity was far less green. We have been largely reliant on the burning of fossil fuels such as coal. This is a non-sustainable resource which is on the verge of running out. The process of burning these fuels has resulted in dangerous emissions. These have been slowly killing and choking our planet. They are also responsible for releasing toxic chemicals into the environment.
Wind energy helps to negate many of these concerns. It is a limitless resource which is not going to run out. It is also fairly cheap. Wind energy is almost entirely carbon neutral.
How Does It Work?
The most common method for capturing the kinetic energy of wind is the wind turbine. The rotor blades of the turbine work using aerodynamic force. This works in a way which is similar to an airplane wing, or helicopter blade.
As the wind flows across the surface of the blade, the air pressure decreases on one side. The difference in air pressure between the two sides of the blade then creates lift and drag. The force of the lift is stronger than that of the drag. This is what causes the rotor to spin round. This rotor is then attached to a generator, and the force creates electricity!
What Are The Advantages?
- It uses a limitless resource.
Unlike resources such as coal or natural gas, wind is inexhaustible. This allows a virtually limitless source of energy with no concerns about running out.
- It is non-polluting.
Perhaps the biggest advantage is that it almost entirely carbon-neutral. This means that there are no gases or other pollution released. Left unchecked, these can be pumped into the atmosphere and cause damage. There are no emissions to damage the planet. Rivers and oceans are also safe. There are no unpleasant waste products. Wind energy also lacks hazardous chemicals or pollutants.
- There is potential to scale up.
Wind can generate energy on a huge scale. This makes it perfect for large towns or cities. It also suits more remote regions which may be otherwise cut off.
- It is safe.
Unlike nuclear energy, there is no risk attached to wind power. Nearby communities will not live in constant fear of meltdowns or accidents. There are also no risks or dangers from the waste. This can often be generated as a byproduct of electricity.
- It is sustainable.
Wind energy has the potential to provide long term reliable and steady electricity. This is especially true when used in combination with solar power. No matter how much electricity is used today, there will be more wind along tomorrow. This is one of the only energy sources which can keep up with our global demand. It also causes minimal damage to the environment.
- It is a space saver.
Wind turbines do not require large areas of land to be cleared. Instead, they sit on a far smaller area. Once installed, the land around wind turbines can be used. It remains accessible to a range of other industries, including farming.
- It is a low cost solution.
Many environmental solutions and ideas are often dismissed for cost. The wind, however, allows for a cheap and sustainable energy source. Wind turbines cost far less to install than fossil-fueled generators. Even better, they do not require extra fuel to run the system.
- It can aid development.
Wind turbines are also simple, straightforward and cheaper to run and install. This means they are perfect in areas which lack infrastructure. They can also be invaluable for developing countries. These may require a cheap but reliable form of electricity which wind can offer. This can allow nations in the developing world to become energy independent. They no longer have to rely on large powers for their energy. This can provide a vital element of international growth and development.
- It can spread rapidly.
Some systems which can take months or years to get off the ground. Wind turbines, however, incur a relatively low cost. This makes them far more adaptable and achievable for companies all over the world. This makes the process of switching to a renewable energy source far more simple. In addition, it is more affordable and so far more likely to occur!
Wind energy symbolises the future of commerce and industry. We all use electricity on a daily basis. Wind energy offers a wonderful and efficient method to generate this. We look at the disadvantage discussion here so we decided we needed to keep an unbiased opinion on this.
