The global demand for electricity is expected to double by 2050, and while carbon-free electricity sources like wind and solar power have grown faster than expected, they have not been able to outpace the growth in demand, leading to a continued reliance on fossil fuels. Coal and gas, the most common sources of electricity production, are also the most polluting, and their continued use is pushing carbon emissions to dangerous levels. While some countries, like China, the world's largest producer and consumer of electricity, still rely heavily on coal, they are also making significant strides in carbon-free power. Other countries, like Paraguay, Iceland, Sweden, and Uruguay, get more than 95% of their electricity from low-carbon sources, while many others are still heavily dependent on fossil fuels. As the demand for electricity continues to rise, the challenge of transitioning to cleaner energy sources becomes increasingly urgent.

What You'll Learn
The rise of renewable energy sources
The world is witnessing a significant shift towards renewable energy sources, with countries increasingly adopting wind, solar, hydropower, geothermal, biomass, and tidal power. This transition is driven by the need to address climate change, reduce air pollution, and improve public health. Since the Industrial Revolution, fossil fuels have dominated the energy mix of most countries, contributing to global climate change and local air pollution. To combat these issues, renewable energy sources are being tapped into, with their potential yet to be fully harnessed.
Hydroelectric power has been one of the oldest and largest sources of low-carbon energy, but its scale varies globally. Wind and solar power, on the other hand, have experienced rapid growth, with solar maintaining its status as the fastest-growing electricity source for the past 19 years. In 2023, solar and wind energy pushed the world past a significant milestone, with renewables accounting for over 30% of global electricity for the first time. This growth is expected to continue, with the International Renewable Energy Agency (IRENA) estimating that renewable energy sources could provide 65% of the world's electricity by 2030 and decarbonize 90% of the power sector by 2050.
Several countries are leading the way in renewable energy adoption. For instance, France obtains around three-quarters of its electricity from nuclear power, while Chile has met its rising power demand primarily through renewable sources. China, despite being the world's largest producer and consumer of electricity, is also expanding its carbon-free power sources, particularly wind and solar. However, coal continues to dominate electricity generation in other rapidly developing countries, such as India, where officials argue that coal is necessary for economic development and providing affordable power to millions.
The transition to renewable energy offers multiple benefits beyond environmental and health impacts. It can drive inclusive economic growth, create new jobs, and alleviate poverty. Additionally, renewable energy sources are now the cheapest power option in most parts of the world, with prices for solar and wind energy dropping significantly in recent years. This makes renewable energy more attractive, especially to low- and middle-income countries.
The future of renewable energy looks promising, with world leaders committing to tripling global renewables capacity by 2030 at the UN's COP28 climate change conference. This target would align with the 1.5C climate goal and significantly reduce power sector emissions. While challenges remain, such as the upfront costs of renewable energy projects, the world is undoubtedly witnessing a significant rise in renewable energy sources that will shape the future of electricity generation.

The continued dominance of fossil fuels
Despite the increasing adoption of renewable energy sources, fossil fuels continue to dominate the global electricity generation landscape. In 2023, over 60% of electricity worldwide was produced using fossil fuels, with coal, natural gas, and petroleum being the primary sources. This dominance is particularly evident in several key countries, including the United States (59%), China (65%), India (75%), Japan (63%), Poland (73%), and Turkey (57%). China, the world's largest producer and consumer of electricity, relies heavily on coal to meet its soaring power demands, although it has also significantly expanded its carbon-free power sources in recent years.
The persistence of fossil fuels in the energy mix can be attributed to several factors. Firstly, rapidly developing countries, particularly in Asia, continue to rely on coal as it is more affordable and provides reliable power to support their economic growth. For instance, India, the world's most populous nation, has ambitious renewable energy targets but still needs coal to power its development. Additionally, the upfront costs of renewable energy projects, such as wind and solar, pose financial challenges for many developing countries, despite their lower lifecycle costs compared to fossil fuels.
While some countries have made strides toward renewable energy, others have experienced setbacks. For example, Japan initially moved away from nuclear power after the Fukushima disaster but has since reversed course. Similarly, South Africa's transition away from coal has been complicated by its struggles to deliver consistent power to its residents. These examples highlight the complexities and varying trajectories countries face in their energy transitions.
The continued reliance on fossil fuels, particularly coal, has significant implications for global carbon emissions and climate change. Despite the expansion of carbon-free electricity sources like wind and solar, the absolute growth in coal-fired electricity generation has pushed carbon emissions upward. This dynamic is at odds with the urgent need to reduce emissions to avoid dangerous levels of global warming. As a result, the energy sector faces mounting pressure to transition away from fossil fuels and toward more sustainable alternatives.
However, there are signs of progress and reasons for cautious optimism. While fossil fuels still dominate, renewable energy sources are gaining traction. The share of electricity generation from renewables has been growing, and in some countries, such as Chile, rising power demand has been predominantly met by renewable sources. Additionally, China, a major global electricity producer, is approaching a turning point where carbon-free power sources are expected to surpass coal-fired electricity in the coming years. This shift in China could significantly impact global emissions and accelerate the transition toward cleaner energy sources.

Nuclear power's changing role
Nuclear power is a significant source of electricity, with nuclear reactors worldwide helping to avoid the emission of 72 billion tonnes of carbon dioxide since 1970. It is a form of low-carbon energy generation, producing heat and electricity through nuclear fission. This process involves the nucleus of an atom, such as uranium-235, splitting into smaller nuclei and releasing neutrons, energy, and radiation. This energy is then converted into electricity in nuclear power plants.
The role of nuclear power in electricity generation is changing country by country. In 2015, the global trend was for new nuclear power stations to be balanced by the retirement of old plants. France, for example, obtains around three-quarters of its electricity from nuclear power. In contrast, Japan has been phasing out nuclear power following the 2011 Fukushima disaster, instead focusing on renewable energy sources.
China, the world's largest producer and consumer of electricity, has been increasing its nuclear capacity. In 2019, 5% of its electricity came from nuclear power, and it had 45 reactors in operation with plans to build more. However, China has also faced challenges with the economics of energy generation, as the country may shift towards cheaper and more reliable renewable energy sources.
While nuclear power has helped reduce carbon emissions, there are concerns about the environmental impact of nuclear power plants, particularly the risk of accidents and the management of nuclear waste. The changing climate and increasing frequency of extreme weather events pose threats to nuclear power plants, which require cooling water and are vulnerable to flooding and hurricanes.
Overall, nuclear power plays a significant role in global electricity generation, and its low-carbon benefits are being weighed against the potential risks and the emergence of more affordable renewable energy sources.

Country-specific electricity production trends
China, for example, is the world's largest producer and consumer of electricity, representing 55% of consumption in Asia and 31% globally in 2023. China overtook the United States as the largest power producer in 2010, and its electricity demand has been predominantly fulfilled by coal, the most polluting fossil fuel. However, China has also significantly expanded carbon-free power sources in recent years, particularly wind and solar. Energy analysts predict that China's carbon-free power will soon displace coal-fired electricity.
The United States, the second-largest electricity producer, has a higher per-person electricity generation rate than China. While the US has historically relied on fossil fuels, it is gradually transitioning to renewable energy sources.
Other countries, such as India, the world's most populous nation, are also setting ambitious renewable energy targets. However, India's officials maintain that coal is still necessary for economic development and providing affordable power to its massive population.
Some countries, like Chile, have managed to meet their rising power demands primarily through renewable energy sources. France, on the other hand, obtains a significant portion (around three-quarters) of its electricity from nuclear power, while Sweden and Uruguay rely heavily on hydropower.
In contrast, countries like Japan, Saudi Arabia, and the Middle East have continued to rely on nuclear power, oil, and gas to meet their rising energy demands. Indonesia has expressed its intention to phase out coal power by 2040, provided it receives sufficient financial support from wealthy nations to invest in cleaner energy alternatives.
While carbon-free electricity sources like wind and solar have experienced rapid growth, they have not kept pace with the escalating global demand for electricity, allowing fossil fuels to retain their dominance in the energy mix.

The impact of electricity demand on carbon emissions
Global Electricity Demand and Carbon Emissions
Electricity demand varies across countries, with China being the largest consumer of electricity, accounting for 31% of global consumption in 2023. The sources used to meet this demand have a direct impact on carbon emissions. Globally, coal remains the largest source of electricity production, followed by gas, contributing significantly to carbon emissions. Despite the rapid growth of wind and solar power, the demand for electricity has outpaced the expansion of clean energy, leading to a continued reliance on fossil fuels. This dynamic has resulted in rising carbon emissions from the power sector, which scientists warn needs to be urgently addressed to mitigate global warming.
Country-Specific Context
Each country's electricity mix is unique, and the transition to low-carbon sources varies. China, the world's largest electricity producer, has relied heavily on coal to meet its soaring power demand. While China has significantly expanded wind and solar energy, coal-fired generation continues to grow. India, the most populous nation, has renewable energy targets but relies on coal for economic development and affordable power for its massive population. Indonesia aims to phase out coal by 2040 with financial support for cleaner energy. Chile has met rising power demand primarily with renewable energy, while Saudi Arabia and the Middle East rely almost entirely on oil and gas. Japan is transitioning away from nuclear power after the Fukushima disaster, and South Africa faces challenges in delivering consistent power amid coal decline.
Carbon Pricing and Demand Flexibility
Carbon pricing mechanisms, such as Australia's carbon price, can influence electricity demand and emissions. During the scheme's first two years, electricity demand in the National Electricity Market (NEM) decreased by 3.8%, and overall emissions by 8.2%. Carbon pricing also led to shifts in the supply mix, with emissions-intensive generators reducing output. Demand flexibility strategies enable buildings to manage their electric demand, providing grid services that can help reduce emissions. Local laws, like New York City's Local Law 97, aim to reduce emissions associated with electricity use in buildings by setting performance expectations based on carbon emissions.
Renewables and the Future
Renewable energy sources like wind, solar, hydropower, and geothermal offer a pathway to reducing the impact of electricity demand on carbon emissions. While upfront costs can be a barrier, particularly for developing countries, the lifecycle costs of renewables are more cost-competitive than fossil fuels. As countries navigate their unique energy transitions, a combination of policy interventions, carbon pricing, demand flexibility, and investments in renewable energy infrastructure will be crucial in mitigating the impact of electricity demand on carbon emissions.
