Wind energy is a type of renewable energy that is becoming increasingly popular all over the world, including the United Kingdom. This is because wind energy has many benefits over traditional forms of energy, such as coal and oil. In this article, we will explore why wind energy is considered a renewable resource and what this means for the UK.
Renewable energy is defined as energy that comes from natural resources that are replenished over time. Wind energy is considered a renewable resource because it relies on the natural movement of air. The wind is created by the uneven heating of the Earth’s surface, which causes air to move from areas of high pressure to areas of low pressure. This movement of air can be harnessed to generate electricity.
Wind energy is a clean source of energy that does not produce any carbon emissions or other pollutants. This makes it an attractive option for governments and businesses who are looking to reduce their carbon footprint and meet their climate change goals. In the UK, wind energy has become a key part of the country’s energy mix, accounting for around 20% of electricity generation in 2020.
One of the main advantages of wind energy is that it is abundant and widely available. The UK is particularly well-suited to wind energy because it is an island nation with a long coastline and open plains that are ideal for wind turbines. The UK is currently home to some of the largest wind farms in the world, such as the Walney Extension Offshore Wind Farm in Cumbria, which has a capacity of 659 megawatts.
Another advantage of wind energy is that it is relatively cheap and cost-effective. The cost of wind energy has decreased significantly in recent years, due to advances in technology and economies of scale. This has made wind energy more competitive with traditional forms of energy, such as coal and gas. In fact, wind energy is now one of the cheapest forms of energy in the UK, with the cost of onshore wind energy falling by 50% between 2015 and 2020.
However, wind energy also has some disadvantages that need to be addressed. One of the main challenges of wind energy is that it is intermittent and unpredictable. The wind does not blow at a constant speed or direction, which means that wind turbines do not always generate electricity when it is needed. This can cause problems for the electricity grid, which needs to be able to balance supply and demand in real-time.
To address this challenge, the UK government has invested in new technologies and infrastructure that can help to manage the variability of wind energy. For example, the UK has developed a smart grid that can adjust the flow of electricity in response to changes in demand and supply. The UK has also invested in energy storage technologies, such as batteries and pumped hydro storage, which can store excess energy generated by wind turbines for use when the wind is not blowing.
In conclusion, wind energy is considered a renewable resource because it relies on the natural movement of air, which is replenished over time. Wind energy is a clean and abundant source of energy that has many benefits over traditional forms of energy. In the UK, wind energy has become a key part of the country’s energy mix, accounting for around 20% of electricity generation in 2020. While there are some challenges associated with wind energy, such as intermittency, the UK government has invested in new technologies and infrastructure to address these issues and ensure that wind energy continues to play an important role in the country’s energy future.
