The debate around electric companies and fossil fuel companies often revolves about which produces more waste. Fossil fuels are currently the dominant energy source, with a large share of the US electricity generation market. However, the fossil energy system is incredibly inefficient, wasting almost two-thirds of all primary energy in production, transportation, and use. In contrast, electric vehicles emit 64% less CO2 and recycle their batteries, while fossil fuel cars burn the equivalent of a 25-storey stack of oil barrels over their lifetime. Nuclear power plants, which provide 19% of US electricity, produce radioactive waste that must be stored securely, but they do not produce greenhouse gases or other harmful emissions.

Fossil fuel cars vs electric cars
Electric vehicles (EVs) are superior to fossil fuel cars in terms of raw material demand, energy efficiency, cost, and the elimination of exhaust emissions of carbon dioxide and other harmful gases. However, the production of electric car batteries requires the mining and intensive processing of minerals like lithium, cobalt, and nickel, which can create significant emissions.
The environmental impact of electric cars is influenced by the energy sources used to charge them. In countries like Norway, where most energy is derived from hydropower, EVs have a minimal carbon footprint. In contrast, countries relying heavily on coal for electricity generation may not see as significant a reduction in emissions from transitioning to EVs. However, even in these countries, EVs are still on par with or better than burning gasoline in terms of emissions.
On average, gasoline cars emit more than 350 grams of CO2 per mile driven over their lifetimes. In comparison, EVs are responsible for lower levels of greenhouse gases, with manufacturing and end-of-life disposal accounting for around 29% of an EV's emissions, while a gas car's emissions are around 9%. EVs use approximately 87-91% of the energy from the battery for propulsion, while gasoline vehicles only convert about 16-25% of the energy from gasoline into movement.
The environmental costs of higher battery production for EVs must also be considered. While increased mining of minerals will be necessary, T&E argues that the environmental toll of oil extraction for fossil fuel cars is much greater. Over its lifetime, an average fossil-fuel car burns the equivalent of a stack of oil barrels 25 storeys high. In contrast, if battery materials are recycled, only around 30kg of metals would be lost per car.
In summary, while the production of electric vehicle batteries can result in significant emissions, EVs still produce far less waste than fossil fuel cars. The environmental impact of EVs is also heavily dependent on the energy sources used to charge them, with renewable energy sources like wind and solar resulting in lower total GHG emissions associated with EVs.

Fossil fuel power plants
Fossil fuels are responsible for a significant amount of waste and pollution. Fossil fuel power plants and internal combustion engines (ICEs) are responsible for almost half of the energy waste globally. The three main drivers of energy waste in production processes are extraction, fuel processing losses, and power generation losses. Power generation losses are the largest, with thermal losses from coal and gas power plants accounting for the majority of this waste. Fossil fuel power plants also release a wide range of pollutants into the environment, including toxic air pollution and solid and liquid wastes such as ash, sludge, and boiler slag. These wastes are often disposed of at or near the power plants, posing risks to groundwater and the environment.
Coal-fired power plants are a significant contributor to dangerous emissions. They generate 35% of mercury emissions in the United States, two-thirds of sulfur dioxide emissions, and most soot (particulate matter). Fossil fuel combustion also emits carbon dioxide (CO2), a greenhouse gas contributing to global warming and climate change. Additionally, burning oil, coal, and gas increases ocean acidity, with oceans absorbing a quarter of man-made carbon emissions, leading to a 30% increase in acidity since the Industrial Revolution.
Fossil fuel technologies are inefficient, vulnerable to competition from more efficient alternatives. The transition to cleaner and more efficient energy sources, such as wind and solar power, is already underway due to federal, state, and local policies promoting renewable energy. This shift is aided by the rising inefficiency of fossil fuel technologies, which drives up costs and makes them less competitive.
While the move towards electric vehicles and renewable energy sources is positive, it is important to consider the environmental costs of higher battery production and mineral mining. However, the overall environmental toll of oil extraction and fossil fuel vehicle waste is significantly higher.
In summary, fossil fuel power plants contribute significantly to waste and pollution through energy waste, toxic emissions, and inefficient technologies. The transition to renewable energy sources and electric vehicles is crucial to reducing the environmental and health impacts of fossil fuel combustion and power generation.

Greenhouse gas emissions
The transportation sector is the largest source of direct greenhouse gas emissions. Over 94% of the fuel used for transportation is derived from petroleum, resulting in significant emissions from vehicles, trucks, ships, and trains. However, it is important to note that the transition to electric vehicles can significantly reduce emissions. Electric vehicles emit 64% less CO2 over their lifetime, even when considering the emissions associated with battery production and electricity generation for recharging.
The industrial sector is the third-largest source of direct emissions. When indirect emissions from electricity use are included, industrial activities account for a much larger share of US greenhouse gas emissions. Commercial and residential buildings also contribute to emissions, primarily from burning fossil fuels for heat and using gases for refrigeration and cooling. Additionally, the commercial and residential sectors consume large amounts of electricity, contributing to indirect emissions.
Nuclear power plants, on the other hand, do not produce greenhouse gases. While nuclear energy generation produces some emissions during the construction of the plant, it does not emit CO2 during operation. Renewable energy sources, such as wind and solar, also have lower greenhouse gas emissions over their life cycles compared to fossil fuels.
Overall, the burning of fossil fuels for electricity generation, transportation, industrial processes, and commercial and residential uses are significant contributors to greenhouse gas emissions. However, the transition to electric vehicles and renewable energy sources, along with improvements in battery technology, can help reduce emissions and mitigate the environmental impact.

Nuclear power plants
Nuclear waste is classified into three types based on radioactivity: low-, intermediate- and high-level waste. Low-level waste, which constitutes 90% of the total volume, includes lightly contaminated items such as tools, clothing, and wiping cloths. This waste is stored at nuclear power plants until its radioactivity decays to safe levels, after which it can be disposed of as ordinary trash or sent to a low-level waste disposal site. High-level waste, such as spent nuclear fuel assemblies, must be stored in specially designed containers and facilities.
The management of nuclear waste is subject to strict regulations to protect human health and the environment. Strategies include direct disposal, where waste is sealed in underground repositories, and recycling, where plutonium is reused to generate electricity and reduce the radiological footprint. The radioactivity of nuclear waste naturally decreases over time through radioactive decay, and the amount of radioactive material that could potentially leak is minimal, posing little health risk.
While nuclear power plants produce waste, the volume is relatively small compared to other industries, and effective management strategies are in place. Nuclear energy offers a significant advantage over fossil fuels in terms of waste production, as fossil fuels generate substantial amounts of ash and carbon emissions, contributing to environmental and health issues.

Raw material extraction
In contrast, low-carbon electricity sources, such as wind and solar energy, require minimal extraction and processing energy, resulting in significantly reduced mining requirements. The transition to these energy sources will lower the total material requirements, even when considering the increased demand for metals and minerals in electric vehicle batteries.
While electric vehicles have been criticized for their reliance on raw materials, the environmental cost of battery production is significantly lower than that of oil extraction for fossil fuel vehicles. Over its lifetime, a typical fossil-fuel car burns the equivalent of a stack of oil barrels 25 storeys high, while an electric vehicle's battery recycling can limit metal loss to around 30kg.
Additionally, the development of battery technology is expected to reduce the demand for minerals like lithium, nickel, and cobalt, further mitigating the environmental impact of raw material extraction for electric vehicles.
In summary, while raw material extraction is necessary for both fossil fuel and electric companies, the latter generally produces less waste due to reduced mining requirements and the recyclability of battery materials.

Frequently asked questions
Fossil fuel companies produce more waste. In fact, almost two-thirds of all primary energy is wasted in fossil fuel energy production, transportation, and use, before fossil fuel has done any work or produced any benefit. This amounts to a loss of over $4.6 trillion per year, which is about 5% of global GDP and 40% of what we spend on energy.
Fossil fuels are the dominant source of energy in the market, with a 62.7% share of the US electricity generation market. The burning of fossil fuels releases carbon emissions, contributing to the greenhouse effect, which warms the Earth. This, combined with increasing levels of greenhouse gases, is causing global warming, which will have profound implications, according to climate scientists.
Wasted electricity leads to unnecessary carbon and methane emissions, contributing to global warming and climate change. The continued warming of the Earth will result in scorching summers and brutal winters, melting polar ice caps, and rising sea levels, which will make most of the US uninhabitable.
Electric vehicles emit 64% less CO2 than fossil fuel cars, even when considering electricity generation and fuel production. Additionally, the raw materials required for electric car batteries can be recycled, whereas fossil fuels cannot be recycled.
