What is the country that uses the most solar energy?



Introduction: An Overview of Solar Energy Utilization Around the World

Solar energy is one of the oldest and most widely used renewable energy sources in the world. It is a clean, reliable, and abundant energy source that has long been at the forefront of the global energy transition. Solar energy is increasingly being used to replace fossil fuel-based power plants and to power homes, businesses, and transportation. According to a recent report by the International Energy Agency (IEA), global solar energy capacity is projected to nearly double by 2023 and account for almost one-sixth of global electricity generation.

China’s Leadership in Solar Energy:

China is now the undisputed world leader in solar energy, having invested heavily in the deployment of solar panels both domestically and around the world. According to the National Energy Administration (NEA) of China, the country has invested over $100 billion in solar energy since 2014, more than any other country. This has propelled China to the top of the solar energy ladder, with more installed solar capacity than any other country in the world. At the end of 2020, the country had more than 254 gigawatts (GW) of installed solar power and remained the world’s leading destination for both utility scale and rooftop solar installations.

A. China’s Impressive Gains in Solar Energy Investment and Generation

The tremendous growth of China’s solar energy industry in recent years can be attributed to a number of factors. First and foremost, China’s vast population continues to drive a rapid economic expansion, leading to an increasing demand for electricity. This demand is largely supplied by solar energy, with China having become the world’s top solar energy investor and generator in 2019. China has also become a key leader in solar research and development, with the Chinese Academy of Sciences (CAS) launching multiple major solar energy research initiatives in recent years.

B. Positioning of China as the World Leader in Solar Energy

China’s leadership in solar energy has led to the country becoming something of a global role model for renewable energy transition. In addition to being the world’s largest investor in solar energy, China is also the world’s largest exporter of solar products. This includes both photovoltaic cells and modules, a key part of any solar system. The country has also established itself as the go-to destination for solar system construction projects, with large scale projects like the Tengger Desert Solar Park acting as a global symbol of the country’s commitment to renewable energy transition.

Comparison of China to the European Union and United States in Terms of Solar Energy Usage

A. Comparing the Cumulative Solar PV Capacity in 2021

China is the world leader in solar energy in terms of both capacity and generation. Its 254 GW of installed solar capacity is far ahead of both the European Union (EU) and the United States (US), which have 152.9 GW and 75.6 GW of installed capacity respectively. This gap is even more pronounced when looking at total annual installations, with the difference between China and the EU almost doubling that of China and the US. In 2021, China is estimated to add nearly 47 GW of additional capacity while the EU and US are estimated to add 27.8 GW and 17.5 GW respectively.

B. Looking at Percentage of Growth from 2016-2020 in Major Solar Players

In addition to comparing total cumulative solar capacity, it is also important to look at the growth of each country’s solar energy sector over the past five years. In this time period, China’s solar capacity has grown more than sevenfold, from 34.5 GW of 2016 to 254.3 GW of 2021. This level of growth is unparalleled by any other country, and is likely to continue as the country continues to invest in the sector. The EU and US have also seen impressive growth in their solar energy sectors in recent years, with capacity increasing seven- and fivefold respectively.

An Analysis of Other Leading Countries in Terms of Solar Energy Usage

A. Rundown of the Top 10 Countries with the Highest Cumulative Solar PV Capacity

China may be the undisputed leader in solar energy generation and installation, but there are many other countries that have made significant investments in the sector as well. Germany, Japan, India, and Italy are all major players in the solar industry, and each country has amassed substantial amounts of solar capacity. The top 10 countries with the highest cumulative solar PV capacity in 2021 are as follows:

Country | Cumulative Solar PV Capacity (GW)
:—————– | :——————
China | 254.3
European Union | 152.9
United States | 75.6
Japan | 41.1
India | 34.0
Germany | 33.7
Italy | 23.2
Australia | 13.0
France | 11.9
UK | 9.9

B. Drill Down into the Top Countries and their Contribution to the Overall Solar Energy Sector

Each of the abovementioned countries has had their own unique strategies and initiatives in the solar energy sector, ranging from ambitious installation targets to generous financing schemes. China’s leadership in solar energy is the result of its robust investments in the sector and its success in developing lower cost solar technology, particularly in the form of crystalline silicon photovoltaics (CSPVs). Germany and Japan have both implemented generous financial incentives to increase solar installations, while India and Italy have both adopted ambitious solar energy installation targets. Australia and France have also been leaders in the sector, with both countries making heavy investments in large-scale solar farms.


In conclusion, the world’s solar energy sector has seen rapid growth over the past decade. China is the undisputed leader in solar energy with more installed capacity than any other country and an unparalleled commitment to the sector. The European Union and United States are also major players in the global solar sector, having invested heavily in solar installations in recent years. Other countries such as Germany, Japan, India, and Italy have also made significant contributions to the solar energy sector, with each deploying major solar energy projects and incentives.

Implications and Further Reading

The rapid expansion of the global solar energy sector is having a profound impact on our energy landscape. Solar energy is becoming increasingly competitive compared to other forms of energy, leading to more countries investing heavily in the sector and more of a focus on renewable energy sources rather than fossil fuels. The implications of China’s leadership in solar energy could lead to further collaborations between countries in the sector, as well as greater investments in solar from other countries as well.

Sources and the Following Question: What is the Country that Uses the Most Solar Energy?

The answer to the question of which country uses the most solar energy is China. According to the IEA, China has the world’s highest cumulative solar energy capacity, totaling 254 gigawatts (GW) at the end of 2020. This is more than double that of the European Union and United States, which had 152.9 GW and 75.6 GW of installed capacity respectively. China is also the world’s leading destination for both utility scale and rooftop solar installations, making it clear that the country is the world leader in solar energy.
