Electricity is essential to modern life, but it has negative effects on the environment and human health. In the US, about 62% of electricity in 2022 was produced from fossil fuels, which release harmful substances when burned, including carbon dioxide, carbon monoxide, and nitrogen oxides. These emissions contribute to global warming, air pollution, and acid rain, which harms plants, animals, and ecosystems. Nuclear power plants produce radioactive waste that remains hazardous for centuries, and renewable energy sources like wind and solar power can also have negative impacts, such as endangering flying animals and causing landscape changes. Wasted electricity exacerbates these issues, with 67% of energy generated in the US in 2017 going to waste. Reducing environmental impacts requires energy efficiency, clean generation methods, and distributed generation technologies like onsite solar panels.

What You'll Learn
Electricity generation and delivery can harm local wildlife
Electricity generation and transmission can negatively impact the environment and local wildlife. In the United States, about 62% of electricity was produced from fossil fuels in 2022. Fossil fuels, such as coal, natural gas, and petroleum, contribute to greenhouse gas emissions, specifically CO2, which contributes to the greenhouse effect. Additionally, the combustion of these fuels produces harmful substances such as SO2, which causes acid rain that is detrimental to aquatic life and plants. NOx, another byproduct of combustion, contributes to ground-level ozone, which is harmful to respiratory health.
The infrastructure required to transmit electricity also affects the environment and wildlife. Transmission lines and distribution infrastructure are often above ground and alter the visual landscape, particularly in undeveloped areas. The vegetation near power lines may need to be continually managed, impacting native plant populations and wildlife. While placing power lines underground is an option, it is more expensive and typically limited to urban areas.
Renewable energy sources, such as wind and solar power, are becoming increasingly important in the energy landscape. However, they too can pose risks to wildlife, including threatened and endangered species. For example, wind energy development can disrupt the migration routes of birds and bats, as well as marine mammals in the case of offshore wind farms. Similarly, large arrays of solar panels may polarize light in a way that mimics water, confusing birds in flight, leading them to attempt to land on solar facilities, contributing to bird fatalities.
To mitigate these impacts, various strategies are employed. Wind energy developers and site operators collaborate with organizations like the Renewable Energy Wildlife Institute to identify solutions and implement technologies to minimize adverse effects on wildlife. Protocols for wind energy projects include using radar and thermal cameras to monitor bird and bat activity, pausing construction when wildlife is present, and installing ultrasonic acoustic devices to deter bats from approaching turbines. Once operational, site operators may slow or stop wind turbine blades when animals are present and use deterrent technology to prevent wildlife from approaching.

Fossil fuels produce harmful emissions
Fossil fuels, such as coal, oil, and gas, are formed from the decomposition of carbon-based organisms that died millions of years ago. They are non-renewable and currently supply around 80% of the world's energy, with about 62% of electricity in the United States generated from fossil fuels.
When fossil fuels are burned, they produce large quantities of carbon dioxide, a greenhouse gas that contributes to global warming and climate change. In 2018, 89% of global CO2 emissions came from fossil fuels, with coal being the most carbon-intensive and the single largest source of global temperature rise. The combustion of fossil fuels also releases other harmful gases such as ozone, sulfur dioxide, nitrogen oxides (NOx), and particulate matter. These emissions contribute to smog, acid rain, and water pollution, with sulfur and nitrogen oxides being particularly harmful to aquatic life. Additionally, coal-fired power plants are major sources of mercury and soot emissions, further exacerbating air pollution.
The burning of fossil fuels has far-reaching consequences for both the environment and human health. The release of nitrogen oxides contributes to the formation of smog and acid rain, which have detrimental effects on respiratory health, especially in children and the elderly. Particulate matter (PM) resulting from fossil fuel combustion leads to hazy conditions in cities and scenic areas, and when coupled with ozone, it contributes to asthma and chronic bronchitis. Fine PM is also believed to cause emphysema and lung cancer.
To mitigate the harmful emissions produced by fossil fuels, efforts have been made to scale up renewable energy sources and improve energy efficiency. Regulations and incentives have been implemented to reduce carbon pollution and promote cleaner energy alternatives, such as wind and solar power. It is important for organizations and individuals to buy renewable energy, conserve energy, and adopt energy-efficient technologies to reduce their environmental impact and contribute to the global efforts to combat climate change.

Nuclear energy produces dangerous radioactive waste
The generation and transmission of electricity can have a range of negative environmental and health impacts. In the United States, about 62% of electricity was generated from fossil fuels in 2022, which release harmful gases when burned, such as CO2, SO2, NOx, and PM. These gases contribute to global warming, acid rain, and respiratory illnesses. Coal-fired power plants are particularly harmful, with mill tailings leaching into rivers and causing them to run red with sulfuric acid, killing aquatic life.
Nuclear power plants, which provide another major source of electricity, also produce radioactive waste. This waste can be divided into two general types: low-level waste and high-level waste. Low-level waste includes contaminated protective clothing, tools, mops, filters, and other disposable items with small amounts of radioactive particles. This waste is stored at nuclear power plants until it decays to a safe level for disposal as ordinary trash or is sent to a low-level waste disposal site. High-level waste, on the other hand, includes highly radioactive spent nuclear fuel assemblies, which are initially stored in pools of water that act as a radiation shield. This water cools the fuel, and the waste is then stored in specially designed dry storage containers or facilities.
While there have been no reported instances of radioactive release causing harm during the transport of nuclear waste, it still poses a significant danger. The waste must be carefully packaged to ensure shielding from radiation and containment, even in extreme accident conditions. Additionally, the costs of managing and disposing of nuclear waste are substantial, and countries with nuclear power programs must estimate and bear these costs.
The environmental impacts of electricity generation are not limited to emissions and waste. Power plants also require land clearing, access roads, railroads, and fuel delivery infrastructure. The electricity transmission lines and distribution infrastructure can also affect the environment, particularly when above-ground transmission towers are used.
To mitigate these negative effects, various solutions are available, including the adoption of renewable energy sources such as wind and solar power, increased energy efficiency, and the implementation of pollution control measures at power plants.

Greenhouse gas emissions contribute to global warming
The burning of fossil fuels for energy is a significant contributor to global warming. Fossil fuels include coal, natural gas, petroleum, and other gases, and when burned, they release carbon dioxide (CO2) into the atmosphere. CO2 is a greenhouse gas, and its release enhances the greenhouse effect, thereby contributing to global warming. The greenhouse effect is a natural phenomenon where gases in the Earth's atmosphere trap heat from the sun, preventing it from escaping into space. While this effect is essential for maintaining livable temperatures on Earth, human activities, such as burning fossil fuels, have intensified it.
According to the IPCC's Fifth Assessment Report, the global electrical power industry emits an estimated 10 billion tonnes of CO2 annually. This has led to an increase in the Earth's atmospheric carbon dioxide levels, with concentrations of human-induced greenhouse gases higher than ever before. The problem is not limited to CO2 emissions, as the burning of fossil fuels also releases other gases such as methane, nitrous oxide, and fluorinated gases. These emissions contribute to the overall increase in greenhouse gases, exacerbating global warming.
The impact of greenhouse gas emissions on global warming is measured through their Global Warming Potential (GWP). GWP quantifies the amount of energy absorbed by emissions per unit mass over a given period, typically 100 years. Gases with higher GWP absorb more energy and contribute more to warming the planet. Additionally, the effect of greenhouse gases on global warming depends on their concentration in the atmosphere, their lifetime, and their effectiveness at trapping heat.
To address the issue of greenhouse gas emissions, various regions are taking action. The EU, for example, has set legally binding targets to reduce emissions by 55% by 2030 compared to 1990 levels and aims to reach net-zero emissions by 2050. The US, through the Clean Air Act, has made strides in reducing emissions from power plants, and end-users can play a role by adopting energy-efficient technologies and purchasing green power.
In conclusion, greenhouse gas emissions from electricity generation, particularly the burning of fossil fuels, have significant negative effects on the environment. The release of carbon dioxide and other greenhouse gases intensifies the greenhouse effect, leading to global warming and consequent shifts in climate patterns. To mitigate these impacts, efforts to reduce emissions and transition to cleaner energy sources are imperative.

Energy generation impacts water usage
Energy generation and water usage are closely interconnected. Water is essential for almost every aspect of energy production, from electricity generation to fossil fuel extraction and biofuels cultivation. The energy sector accounts for a significant portion of global freshwater use, with a notable impact on water resources.
The water consumption of power production can vary across different countries and energy systems. Certain renewable energy sources, such as photovoltaics, wind power, and run-of-the-river hydropower, are known for their relatively low water consumption. In contrast, other sources, such as reservoir hydropower and biomass, can have a significantly larger water footprint.
Thermoelectric power plants, prevalent in the United States, rely on fossil fuels or nuclear fuels to boil water for steam, which then turns turbines to generate electricity. This process requires large volumes of water, and the subsequent cooling of the steam further impacts water usage. Some power plants utilize once-through" cooling systems, where water is used only once before being discharged back into water bodies at higher temperatures, causing thermal pollution that damages aquatic life.
Water stress and scarcity have led to an increased reliance on non-traditional water sources, such as saltwater, which requires desalination. Desalination is an energy-intensive process, often relying on fossil fuels, and its growing demand will further increase energy consumption for water treatment.
To mitigate the impact of energy generation on water usage, several strategies can be employed. Firstly, transitioning to renewable energy sources with lower water footprints, such as wind and solar power, can significantly reduce water consumption. Additionally, improving energy efficiency in water utilities through programs like the Combined Heat and Power (CHP) Partnership can help reduce the environmental impact of power generation. Furthermore, individual actions, such as reducing fossil fuel use, adopting energy-efficient appliances, and practicing water conservation, collectively contribute to lowering the strain on water resources.

Frequently asked questions
Electricity generation and transmission can have a large impact on the environment. Some negative effects include:
- Emissions of greenhouse gases and other air pollutants, especially when a fuel is burned.
- Use of water resources to produce steam, provide cooling, and serve other functions.
- Discharges of pollution into water bodies, including thermal pollution.
- Generation of solid waste, which may include hazardous waste.
- Land use for fuel production, power generation, and transmission and distribution lines.
Most mechanisms for generating electricity release carbon dioxide and other greenhouse gases into the Earth's atmosphere. The overwhelming majority of scientists believe that this contributes to an unnatural degree of global warming, which has the potential to affect the global climate, destroy animal populations, and change local ecosystems.
The negative effects of electricity on human health are often a result of exposure to pollutants in air, water, or soil. For example, the combustion of fossil fuels releases sulfur dioxide (SO2) which causes acid rain and worsens respiratory illnesses and heart diseases, particularly in children and the elderly. Nitrogen oxides (NOx) contribute to ground-level ozone, which irritates and damages the lungs. Particulate matter (PM) in the air results in hazy conditions in cities and scenic areas and, coupled with ozone, contributes to asthma and chronic bronchitis, especially in children and the elderly.
Nuclear power plants do not produce greenhouse gases or air pollutants, however, they do produce radioactive waste. Low-level waste can be stored at nuclear power plants until it is safe for disposal as ordinary trash, or it is sent to a low-level radioactive waste disposal site. High-level waste, which includes highly radioactive spent nuclear fuel assemblies, must be stored in specially designed storage containers and facilities. Nuclear power is also potentially dangerous due to the possibility of accidents at power plants, which can result in the release of radioactive materials into the environment.
The negative effects of electricity can be reduced by buying green power and becoming more energy-efficient. End-users can adopt energy-efficient technologies and practices to reduce the need for electricity generation. Power plants can also reduce environmental impacts by increasing generation efficiency, installing pollution controls, and leveraging cleaner energy supply resources.
