Electricity generation is a major contributor to global warming, which is causing global temperatures to rise. In the United States, the largest source of greenhouse gas emissions is transportation, closely followed by electricity production and industrial activity. Fossil fuels, such as coal, oil, and natural gas, are burned to generate electricity, producing carbon dioxide and nitrous oxide, which are powerful greenhouse gases. As a result, the Earth's atmosphere warms, leading to an increase in global temperatures. This warming triggers climate tipping points, such as the rapid melting of glaciers and thawing permafrost, transforming natural systems and further intensifying warming. The rising temperatures also have significant impacts on energy systems, increasing the demand for cooling and putting pressure on electricity grids, while also making them more vulnerable to extreme weather events such as heatwaves, droughts, and wildfires.

What You'll Learn
Fossil fuels and electricity generation
The burning of fossil fuels, such as coal, oil, gasoline, and natural gas, has led to the greenhouse effect, which is causing global warming. Fossil fuels are the largest source of global carbon dioxide (CO2) emissions. Fossil fuel power stations, which burn fossil fuels to generate electricity, provide most of the electrical energy used in the world. Coal is the most abundant fossil fuel and is widely used as an energy source in thermal power stations. It is also a relatively cheap fuel.
In 2023, about 4.18 trillion kilowatthours (kWh) of electricity were generated at utility-scale electricity generation facilities in the United States. About 60% of this electricity generation was from fossil fuels, including coal, natural gas, petroleum, and other gases. Fossil fuel power plants convert the chemical energy stored in fossil fuels into thermal energy, mechanical energy, and finally electrical energy. Diesel engines are sometimes used in fossil fuel power plants, but they can be subject to problems resulting from water accumulation and chemical decomposition.
While some countries get nearly all of their electricity from nuclear or renewable sources, globally, more than a third of electricity comes from low-carbon sources, with the majority still generated from fossil fuels. The balance between fossil fuels and low-carbon electricity sources has remained relatively unchanged over the past few decades. However, some countries have seen a shift away from coal in recent years, such as the UK.
To limit global warming, there is a need to transition away from fossil fuels and towards cleaner energy sources. The IEA's Global Roadmap to Net Zero by 2050 outlines the need for much more electricity and cleaner electricity to achieve net-zero emissions. Making electricity systems more resilient to the effects of global warming and more efficient and flexible as they incorporate rising levels of solar and wind power will be critical for reaching net-zero emissions.

Climate change and energy infrastructure
Climate change is impacting energy infrastructure in numerous ways, from the generation of electricity to its transmission and consumption. The burning of fossil fuels, such as coal, oil, and natural gas, has led to the greenhouse effect, causing global warming and climate change. As a result, temperatures have risen globally, with the planet experiencing its warmest years on record in the last decade.
The energy sector is vulnerable to the impacts of climate change, including rising temperatures, heatwaves, droughts, intense rainfall, and hurricanes. These impacts strain the energy infrastructure in various ways. For instance, heatwaves increase electricity demand as people use more cooling systems, and power plants themselves require more cooling to function efficiently, reducing their efficiency. Additionally, higher temperatures decrease the carrying capacity of transmission lines, increasing the risk of blackouts and power disruptions.
Wildfires, which are more frequent and intense due to warmer and drier conditions, pose a significant threat to energy infrastructure. They can disrupt energy networks by damaging transmission towers and power lines, as seen in the 2021 Dixie Fire in California, which was sparked by a tree contacting electrical distribution lines. Climate change is also causing sea-level rise, melting sea ice, and thawing permafrost, which are expected to damage oil and gas infrastructure in regions like Alaska, affecting energy production.
To address these challenges, the transition to cleaner and more resilient energy systems is crucial. Many countries have set ambitious targets for reaching net-zero emissions by 2050, which will require a significant increase in clean electricity generation and its integration into various sectors such as transport, buildings, and industry. The IEA's Global Roadmap to Net Zero emphasizes the importance of secure electricity supplies and the need to prioritize the climate resilience of the electricity sector in government policy agendas.
While the shift towards cleaner energy is essential, it is also important to recognize the energy access gap that exists globally. Approximately 1.3 billion people lack access to electricity, while 3 billion rely on burning wood or dung for cooking or heating. Providing modern energy supplies to these populations may have minimal impacts on climate change, but it is crucial for their well-being and development. Balancing the need for universal energy access with the imperative to reduce greenhouse gas emissions remains a complex challenge in the pursuit of a more sustainable future.

Energy demand and electricity supply
As global temperatures rise, energy demand also increases, particularly for cooling. This trend is expected to continue, with the energy demand for cooling potentially tripling by 2050. Heatwaves put pressure on electricity systems as people increase their use of air conditioning and other cooling appliances. Additionally, the carrying capacity of transmission lines decreases as temperatures rise, further straining the electricity supply.
The vulnerability of our energy systems to climate change impacts is evident in the increased frequency and intensity of extreme weather events, such as heatwaves, droughts, and wildfires. These events can directly damage energy infrastructure, leading to power disruptions and blackouts. For instance, the 2021 Dixie Fire in California, sparked by a tree contacting electrical distribution lines, became the largest wildfire in the state's history.
To address these challenges, a transition to cleaner and more resilient energy systems is necessary. This includes incorporating more renewable energy sources, such as wind and solar power, and improving energy efficiency. Achieving net-zero emissions targets, as many countries have committed to, will require a significant increase in clean electricity production and its integration into various sectors like transport, buildings, and industry.
Lastly, it is important to consider the 1.3 billion people without access to electricity and the 3 billion who rely on burning wood or dung for cooking or heating. Providing modern energy supplies to these populations could have a minimal impact on climate change by reducing deforestation and its side effects.

This transition involves adopting cleaner energy sources, such as wind, solar, hydropower, and other renewable sources, while also improving energy efficiency and deploying advanced technologies.
One key aspect of clean energy transitions is the need to transform electricity systems. Electricity production is a significant contributor to global greenhouse gas emissions, particularly in the United States. To achieve net-zero emissions targets, electricity systems must become more resilient, efficient, and flexible in incorporating rising levels of renewable energy. This includes enhancing electricity grids to accommodate the integration of distributed energy resources, such as solar and wind power, and ensuring electricity supply security during extreme weather events, which are becoming more frequent and intense due to climate change.
Several initiatives are underway to support the transition to clean energy and the transformation of electricity systems. The International Energy Agency (IEA) is working with countries worldwide, providing data, analysis, and policy advice on electricity security and clean energy transitions. The IEA's Global Roadmap to Net Zero by 2050 emphasizes the need for more electricity generated from cleaner sources, with electricity playing a more significant role in sectors such as transport, buildings, and industry.
Additionally, interconnectors, or high-voltage cables connecting the electricity systems of neighbouring countries, facilitate the sharing of clean energy and help ensure power availability during high demand periods. Examples include The Great Grid Upgrade in the UK and the Upstate Upgrade in the Northeast US.
The transition to clean energy and the transformation of electricity systems offer both environmental and socio-economic benefits. Renewable energy sources are abundant, self-replenishing, and emit little to no greenhouse gases, helping to reduce pollution and mitigate climate change. They also offer cost advantages, with prices for renewable energy technologies rapidly declining, making them the cheapest power option in most parts of the world. Furthermore, the transition is expected to create numerous jobs in the energy sector and related industries, driving innovation and reducing energy poverty.
To summarize, clean energy transitions, particularly in the electricity systems, are crucial for addressing climate change. By adopting renewable energy sources, improving energy efficiency, and enhancing the resilience of electricity grids, we can achieve net-zero emissions targets and build a more sustainable future. This transition brings about multiple benefits, including environmental, economic, and social advantages, making it a transformative process that prioritizes equity, inclusion, and human development.

The majority of these emissions come from transportation, electricity generation, and other forms of energy production and use. Residential and commercial buildings consume over half of all electricity and emit significant greenhouse gases as they continue to rely on coal, oil, and natural gas for heating and cooling.
Since the Industrial Revolution, the global annual temperature has increased by a little more than 1 degree Celsius. While natural cycles and fluctuations have caused the Earth's climate to change over time, human activity, particularly the burning of fossil fuels, has been the primary driver of the current era of global warming. The manufacturing and industrial sectors are major contributors to greenhouse gas emissions, as they burn fossil fuels to produce energy for various processes and products.
Transportation is another significant source of greenhouse gas emissions, with road vehicles, ships, and planes contributing to the combustion of fossil fuels. Food production and distribution also play a role in emissions, through deforestation, agriculture, livestock digestion, fertilizer use, and energy use. The wealthiest individuals contribute disproportionately to greenhouse gas emissions, with the richest 1% of the global population emitting more than the poorest 50%.
To address global warming, many countries have set targets to reach net-zero emissions by 2050. This will require a significant increase in clean electricity production and its integration into various sectors such as transport, buildings, and industry. However, heatwaves and extreme weather events pose challenges to electricity systems, increasing demand and straining infrastructure.
As the climate continues to warm, the frequency and intensity of extreme weather events are expected to increase, further impacting energy infrastructure. It is crucial to make electricity systems more resilient and efficient to mitigate the effects of global warming and facilitate the transition to cleaner energy sources.
