The United Kingdom is committed to reducing its carbon emissions and becoming a leader in renewable energy. The country has made significant progress in recent years, increasing its use of clean energy sources such as wind, solar, and hydro power. In this article, we will explore how much renewable energy the UK currently uses, the government’s targets for the future, and the challenges that need to be overcome to achieve a more sustainable energy mix.
Renewable energy sources in the UK
Renewable energy sources in the UK include wind, solar, hydro, biomass, and tidal power. According to the latest government statistics, renewable energy sources provided 33.1% of the UK’s electricity in 2018, up from 29.3% in 2017. The majority of this came from wind power, which generated 17.1% of the country’s electricity, followed by biomass (11.2%), solar (4.2%), and hydro (0.9%). Tidal power is still in its early stages of development, but there are plans for several large-scale projects that could potentially generate a significant amount of electricity in the future.
The UK is the world leader in offshore wind power, with more offshore wind capacity than any other country. In 2018, offshore wind generated 8.5% of the country’s electricity, up from 6.2% in 2017. The government has set a target of 40GW of offshore wind capacity by 2030, which would provide a third of the country’s electricity needs.
Solar power has also seen significant growth in recent years, with more than 13GW of capacity installed across the country. However, the government has been criticized for reducing subsidies for solar power, which has slowed down the rate of installations.
Challenges to reaching renewable energy targets
Despite the progress that has been made, there are still significant challenges to achieving the government’s renewable energy targets. One of the main challenges is the intermittency of renewable energy sources, particularly wind and solar power. This means that they are not always available when needed, which can create challenges for grid operators. To address this, the government is investing in energy storage technologies such as batteries, which can store excess electricity generated by renewables and release it when needed.
Another challenge is the lack of infrastructure needed to support renewable energy sources. For example, there is currently a shortage of onshore wind and solar projects, as planning permission for new projects has become more difficult to obtain. The government has also faced criticism for not investing enough in the necessary grid infrastructure to support the growth of renewable energy sources.
Finally, the cost of renewable energy is still higher than that of fossil fuels, although this gap is closing as technology improves and economies of scale are achieved. The government has set a target for renewable energy to be cost-competitive with fossil fuels by 2025.
Government targets for renewable energy
The UK government has set an ambitious target of net-zero carbon emissions by 2050, which will require a significant increase in the use of renewable energy sources. The government’s Clean Growth Strategy sets out a range of policies and initiatives aimed at achieving this target, including:
– A target of 30% of the UK’s electricity to be generated from offshore wind by 2030.
– A target of 40GW of offshore wind capacity by 2030.
– A commitment to phase out coal-fired power plants by 2025.
– A target of 12GW of installed solar capacity by 2030.
– A commitment to invest £2.5 billion in low-carbon innovation by 2021.
Conclusion
The UK has made significant progress in increasing its use of renewable energy sources in recent years, particularly in offshore wind power. However, there are still significant challenges to overcome, including the intermittency of renewable energy sources and a lack of infrastructure to support their growth. The government has set ambitious targets for the future, which will require significant investment and innovation to achieve. If these targets are met, the UK could become a leader in renewable energy and make a significant contribution to the fight against climate change.
