Evolution of UK Power Generation: From Traditional to Renewable Sources

The UK power generation landscape has evolved significantly in the past two decades. Today, the UK fulfils its power needs through various power generation sources, including gas, wind, nuclear, solar, biomass, hydro, and coal. Although gas contributes the major share in generating electricity in the UK, the country is gradually transitioning from traditional fossil fuel sources to renewable sources. In fact, gas and coal-based generation have plunged to 40% in 2022^[1].

Traditional fossil fuel-based electricity generation is increasingly criticised due to climate concerns, expensive power generation, and depletion of finite resources. In response, the UK is actively deploying sustainable alternatives, such as wind, solar, hydro, etc. The UK even recorded 2022 as one of the greenest years for electricity generation^[2]. Therefore, this article thoroughly explores the evolution of UK power generation from traditional to renewable sources.

A Look into the Traditional Power Generation in the UK

Traditional power generation refers to those power generation methods that have been in use for decades. They mainly include generating electricity from fossil fuels, including oil, natural gas, and oil. The UK power generation has relied heavily on these fossil fuel-based methods, mainly natural gas and coal, to produce electricity and meet the nation's growing energy demands. In 2010, 75% of UK power generation was based on traditional fossil fuels, including coal and natural gas^[3].

1. Challenges and Limitations of Traditional Power Generation

Traditional UK power generation had once been groundbreaking, but now it is losing its grounds due to many challenges/limitations and the emergence of alternative sources. To help better understand, below are the key challenges and limitations of traditional power generation worth knowing:

• Price Volatility

The cost of fossil fuels fluctuates based on supply and demand and geopolitical factors. For instance, the Russia-Ukraine war caused huge fluctuations in global oil and gas markets, causing extreme price volatility.

• Import-Based Generation

Most countries don't have enough fossil fuel resources within their borders, making them heavily dependent on importing fossil fuels to run their traditional power generation systems. In fact, UK power generation relies significantly on natural gas, but the country has to import around half of its gas from the international market^[4]. So, this import-based generation increases exposure to supply disruptions, geopolitical risks, and economic vulnerabilities.

• Depleting Resources

Traditional power generation is mostly based on finite resources. Although we currently have enough supply to fulfil global needs, they are non-renewable resources and will eventually become scarce and more difficult to extract.

• Extensive Infrastructure

To generate electricity from traditional methods, there is a need for extensive infrastructure, such as a large transportation network for fossil fuels, massive mining operations, etc. Not just are these infrastructures difficult to run and maintain, but they require significant and continuous financial resources.

• Lack of Scalability

Traditional power generation requires significant construction time, so they are not easily scalable to meet the growing power needs. To scale an existing traditional power system, a country requires more land, more workforce, and more financial budget.

• Safety Concerns

Traditional power generation also brings many safety concerns with it. Accidents, disasters, or malfunctions in traditional power plants can affect both humans and the country's grid supply. For instance, exposure to harmful gases during coal mining, oil and gas spills, nuclear accidents, transportation accidents, human error, thunderstorms, and others raise serious safety concerns.

2. Environmental Impacts of Traditional Power Generation

Besides the above challenges and limitations, another dominant reason behind the increased concern for traditional power generation is the adverse effect on the environment and carbon emissions. The major environmental impacts of traditional power generation are as follows:

• Greenhouse Gas Emissions

Traditional power generation is one of the major sources of greenhouse gas emissions. When fossil fuel is burned, it releases methane (CH4), carbon dioxide (CO2), nitrous oxide (N2O), and others, which contributes to global warming and the greenhouse effect. In fact,  about 75% of the world's greenhouse gas emissions originate from the generation of energy by burning fossil fuels^[5].

• Climate Change

The greenhouse gases released due to traditional power generation accumulate in the atmosphere, which leads to climate change. Rising global temperatures, shifts in precipitation trends, and severe and frequent extreme weather events are all climate changes due to traditional power sources.

• Health Concerns

Traditional UK power generation makes the air polluted with different hazardous pollutants. This can lead to many health concerns among individuals, such as respiratory disorders, heart problems, or even cancer.

• Acid Rain

The burning of fossil fuels during traditional power generation also emits nitrogen oxides and sulphur dioxide. These pollutants can form acid rain, damaging soils, plants, and aquatic environments.

• Water Pollution

Improper extraction of fossil fuels or lack of proper handling of waste can pollute the water and harm the aquatic ecosystem and sea life.

The Rise of Renewable Power Generation in the UK

With the growing awareness of the limitations and hazardous nature of traditional power generation, the UK is actively shifting from traditional to other power generation sources, especially renewable power generation. In 2010, less than 20% of the UK power generation was based on renewable power generation^[6], but now around 47.8% of power is generated through renewable sources in the first quarter of 2023^[7]. The country is rapidly transitioning from traditional to renewable power generation.

1. Key Renewable Energy Sources in the UK

The UK is a country rich in renewable energy sources, that's why the country is trying to exploit all the options to increase renewable-based UK power generation. The key renewable energy sources in the UK include:

• Wind Energy:The UK has plenty of wind resources, including offshore and onshore. The country is even the global leader in offshore wind farms. UK's windy coastlines provide an ideal location to harness wind power and generate electricity.

• Solar Energy:The UK is gradually increasing its solar power production capacity. Besides setting up solar farms, the locals are installing solar panels in homes or commercial places to get clean energy, save electricity costs, and reduce the burden on the grid supply.

• Bioenergy:Bioenergy is another major source of renewable power generation in the UK. It involves using organic materials, organic waste, and agricultural residues to produce heat and electricity.

2. Advantages of Renewable Power Generation

Renewable power generation is the key to reviving the planet's deteriorating condition and having a much cleaner and more reliable power source. The other key advantages of renewable power generation are as follows:

• Sustainability

Renewable power generation is highly appreciated due to its sustainable nature. For example, solar naturally replenish at a faster pace than they are consumed. Moreover, it is inexhaustible. Therefore, it offers a long-term and continuous power supply, leading to more sustainability of the power system.

• Emissions Reduction

Renewable power generation is linked with no to minimal emissions of greenhouse gases. This results in a significant drop in carbon emissions and other harmful pollutants, leading to improved air quality and climate.

• Energy Diversification

Integrating different renewable power sources into the country's grid supply diversifies the energy portfolio. It empowers countries to set up a more flexible and reliable energy system for uninterrupted power supply and enhanced energy security.

• Lower Operating Costs

Renewable power generation does require a proper initial investment. But once the infrastructure is installed, the ongoing operational cost is much lower than traditional power generation. Moreover, renewable energy sources also require lower maintenance expenses, making them cost-effective in the long term.

• Energy Independence

Renewable power generation reduces the country's dependence on imported fossil fuels. The country gets to use its own renewable resources, which are available continuously. This not just gives energy independence but also reduces price fluctuations due to geopolitical situations.

Solar Energy Solutions in the UK

1.  Solar Energy and Its Potential in the UK

Solar energy is all about harnessing sunlight through well-placed solar panels and using the process of photovoltaic effect to convert solar energy into useful electricity. Although the UK is known for its cloudy nature, the country is still actively investing in solar power generation.

The UK installed 555 MW of new PV capacity by the end of December 2022, making its cumulative solar capacity hit 14.3 GW. This is almost a 4% increase from December 2021^[8].

Other than solar farms contributing directly to the UK power generation, the UK government is also launching different government support programs and incentives to encourage UK households to install solar panels in their homes, such as:

• Energy Company Obligation Scheme (ECO4):It provides up to £14,000 grant for energy-saving initiatives.
• VAT Exemption:The UK government has scrapped VAT on solar panels until 2027.
• Smart Export Guarantee:Households are able to receive payments for selling their surplus energy back to the grid.^[9]

In short, the UK is emphasising a lot in solar energy and taking every step to increase its solar capacity with every passing year.

2. The Emergence of Portable Power Stations as Clean and Reliable Power Sources
