Fossil fuels are a major contributor to global warming, and the cost of climate-fuelled natural disasters in the US alone has been $595.5 billion over the last five years. Transitioning to renewable energy sources such as wind and solar is not only beneficial for the environment but also for the economy. In fact, replacing coal plants with local wind and solar would generate $589 billion in new investment across the US. While the upfront cost of transitioning to 100% renewable energy in the US is estimated to be $4.5 trillion, the long-term benefits of renewable energy sources are clear.

What You'll Learn
The cost of replacing fossil fuels with renewable energy sources
Onshore wind and solar are now the cheapest sources of energy for new power generation, even compared to gas or coal. Wind and solar with storage can cost as little as $0.04 per kilowatt-hour (kWh), while fossil fuels can cost up to $0.22 per kWh. The International Renewable Energy Agency (IRENA) found that nearly all US coal capacity (99%) costs more than renewable energy capacity.
There are also significant economic and health costs associated with burning fossil fuels. Air pollution from fossil fuels costs more than $8 billion per day globally, and transitioning to clean energy could bring public health benefits totaling $978 billion in the US by 2050. Additionally, climate-fueled natural disasters cost the US $165 billion in 2021, and $595.5 billion in the last five years.
Overall, while there may be significant upfront costs to replacing fossil fuels with renewable energy sources, the long-term benefits in terms of reduced health and environmental costs, as well as the potential for new investment, make it a worthwhile investment.

The cost of building wind and solar capacity
According to one analysis, to achieve 100% renewable energy in the US over the next 10 years, there would first need to be a massive buildout of wind and solar capacity, costing $1.5 trillion. This would be followed by the addition of 900 gigawatts of battery storage, raising the price tag to $4 trillion. The US would also need to double its transmission lines, from 200,000 miles to 400,000 miles, to handle the new distributed power system, costing another $700 billion.
However, it's important to note that the cost of new power generation from onshore wind and solar is now cheaper than fossil fuels, even without taking into account the significant health and environmental costs of burning fossil fuels. Onshore wind and solar with storage can cost as little as $0.04 per kilowatt-hour (kWh), while fossil fuels can cost up to $0.22 per kWh. A study by Arcadia found that replacing coal plants with local wind and solar would generate $589 billion in new investment across the US.
The International Renewable Energy Agency (IRENA) found that nearly all US coal capacity (99%) costs more than renewable energy capacity, and that the cost of either new wind or solar is at least 30% cheaper than running more than three-quarters of existing US coal plants.
In addition to the economic benefits, transitioning away from fossil fuels to clean energy could have significant public health benefits. The American Lung Association reported that this transition could result in benefits totalling $978 billion in the United States by 2050. Climate-fuelled natural disasters are also a significant cost, with the US spending $165 billion in 2021 alone on these events.

The cost of battery storage
Onshore wind and solar with storage can cost as little as $0.04 per kilowatt-hour (kWh), while fossil fuels can cost up to $0.22 per kWh. This makes renewable energy sources significantly cheaper than fossil fuels, with the International Renewable Energy Agency (IRENA) finding that nearly all US coal capacity (99%) costs more than renewable energy capacity.
Overall, the cost of battery storage is an important consideration in the transition to renewable energy, but it is just one piece of the puzzle. The overall cost of replacing fossil fuels with renewable energy sources also includes the cost of building out wind and solar capacity, upgrading transmission lines, and other infrastructure improvements.

The cost of transmission lines
To replace fossil fuels, the US would need to double its transmission lines from 200,000 miles to 400,000 miles. This would cost $700 billion.
The materials used for transmission lines can also affect the cost. Traditional transmission lines use steel towers and aluminium conductors, which are durable and conductive but expensive. Newer technologies, such as high-temperature superconducting cables, offer improved efficiency and reduced losses but are currently more costly.
Overall, the cost of transmission lines is a critical consideration in the transition away from fossil fuels. While renewable energy sources may be cheaper to operate, the upfront investment in infrastructure, including transmission lines, is a significant barrier to their widespread adoption.

The cost of health problems caused by air pollution from burning fossil fuels
The cost of transitioning to renewable energy sources is high, but the economic and health costs of air pollution from burning fossil fuels are also significant. The American Lung Association reported that transitioning away from fossil fuels to clean energy could have public health benefits totalling $978 billion in the United States by 2050. This is because burning fossil fuels for power and transportation is a huge source of the greenhouse gas emissions that cause global warming.
The economic and health costs of air pollution from burning fossil fuels top $8 billion per day globally. Climate-fuelled natural disasters cost the US $165 billion in 2021, and in the last five years, climate disasters have cost a total of $595.5 billion.
The cost of new power generation is also a factor to consider. Onshore wind and solar are now the cheapest sources of energy, even less than gas or coal. Onshore wind and solar with storage can cost as little as $0.04 per kilowatt-hour (kWh), while fossil fuels can cost up to $0.22 per kWh. The International Renewable Energy Agency (IRENA) found that nearly all US coal capacity (99%) costs more than renewable energy capacity.
Replacing coal plants with local wind and solar would generate $589 billion in new investment across the US. While the upfront costs of transitioning to renewable energy are high, the long-term benefits in terms of public health, reduced climate disasters, and cheaper energy sources make it a worthwhile investment.
