Electric vehicles (EVs) are widely considered to be an effective alternative to traditional fossil-fuel cars. However, it is important to consider the source of electricity used to power these vehicles. In some cases, electric cars may still be running on fossil fuels if the local electricity network is predominantly powered by burning fossil fuels. For example, in California in 2015, 60% of electricity was generated from burning fossil fuels, while solar and wind energy made up less than 14%. This means that even though an electric car does not directly use fossil fuels, it may still be indirectly reliant on them. Additionally, the creation of EV batteries requires the use of fossil fuels to mine and process materials such as lithium, cobalt, and nickel. Despite these considerations, electric vehicles are generally more fuel-efficient and environmentally friendly than traditional gasoline-powered cars.

Fossil fuels are expensive and environmentally destructive
Fossil fuels are expensive, and their costs are only projected to increase. In the United States, fossil fuel spending is expected to grow, with an estimated total of $23 trillion in spending between 2010 and 2030. If fossil fuel prices continue to rise, the United States could spend over $30 trillion on fossil fuels between 2010 and 2030, with fossil fuel expenditures surpassing $1 trillion in 2011. The cost of fossil fuels in the United States electric power industry varies, with an average cost of about $3.12 per million British thermal units (Btu) in 2023, ranging from $2.36 per million Btu for coal to $16.53 per million Btu for petroleum.
The high cost of fossil fuels is not just financial; they also impose massive environmental and health costs. Fossil fuels are a leading source of air and water pollution, with the economic cost of air pollution in sectors regulated under the Clean Air Act estimated at $9 trillion between 1970 and 2000. The production and transport of fossil fuels routinely pollute the environment and occasionally cause catastrophic accidents. For example, the collapse of a coal ash pond outside a Tennessee Valley Authority power plant in 2008 covered 300 acres in sludge and is expected to cost $825 million to clean up. Between 1990 and 2006, 51 large oil spills in the United States resulted in expenditures of between $860 million and $1.1 billion in removal costs and compensation for damages.
Fossil fuels emit harmful air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury, which are detrimental to both the environment and human health. According to a 2017 study, approximately 17.6 million Americans are exposed daily to toxic air pollution from active oil and gas wells and transport and processing facilities. These pollutants have been linked to various health issues, including childhood leukemia, blood disorders, and cancer. Additionally, the burning of fossil fuels releases greenhouse gases, such as carbon dioxide, which contribute to global warming and climate change.
The environmental and health impacts of fossil fuels disproportionately affect communities of color and low-income communities. For example, in "Cancer Alley," a predominantly Black and low-income area of Louisiana, the cancer risk is nearly 50 times higher than the national average due to the proximity of numerous chemical plants and oil refineries. As the demand for fossil fuels continues to grow with population and technological advancements, the environmental and economic costs of their use will also increase. Therefore, it is essential to transition to sustainable energy sources beyond carbon to reduce the destructive impact of fossil fuels on our planet and our health.
