Study Notes

Air Pollution

Burning coal and oil releases pollutants like sulfur dioxide (SO₂), nitrogen oxides (NOx), and particulate matter
These pollutants contribute to smog, acid rain, and respiratory problems

Resource Depletion

Fossil fuels are non-renewable resources
Their extraction and use deplete the Earth's finite reserves

Environmental Degradation

Mining for coal and drilling for oil can cause significant harm to ecosystems and landscapes
Oil spills can have devastating environmental consequences

Nuclear Energy: Positive Impacts

Low Greenhouse Gas Emissions: Nuclear power plants emit very low amounts of CO₂ during operation
High Energy Output: A small amount of uranium produces a large quantity of energy
Stable Energy Supply: Provides a consistent and stable source of electricity

Nuclear Energy: Negative Impacts

Radioactive Waste: Generates hazardous radioactive waste, requiring long-term, secure storage
Nuclear Accidents: Accidents like Chernobyl and Fukushima highlight the catastrophic potential of nuclear power plant failures
High Initial Costs: Building requires significant investment in time and money, and decommissioning is costly

Hydroelectric Power: Positive Impacts

Renewable Energy: A renewable source of energy, relying on the water cycle
No Direct Emissions: Hydroelectric plants do not release CO₂ or other harmful pollutants during electricity generation
Long Lifespan: Hydroelectric power stations can operate for decades with minimal maintenance costs

Hydroelectric Power: Negative Impacts

Environmental Disruption: Building dams can flood large areas of land, disrupt local ecosystems, and displace communities
Altered Water Flow: Dams can change the natural flow of rivers, affecting fish populations and reducing water availability downstream
Vulnerability to Drought: Hydroelectric power generation is highly dependent on water availability, which can be affected by droughts or changing weather patterns

Solar Energy: Positive Impacts

Renewable and Abundant: Solar energy is abundant and renewable, potentially providing electricity in areas that receive a lot of sunlight
No Greenhouse Gas Emissions: Solar power generation does not produce greenhouse gases or pollutants
Scalable: Solar panels can be installed at small scales (rooftops) or large scales (solar farms)

Solar Energy: Negative Impacts

Intermittent Supply: Solar energy is only available when the sun is shining, leading to challenges in providing a consistent energy supply
High Initial Costs: The installation of solar panels and related infrastructure requires significant upfront investment
Land Use: Large solar farms can require vast areas of land, which may lead to habitat loss or conflicts over land use

Wind Energy: Positive Impacts

Clean and Renewable: Wind energy is a renewable and clean source of electricity, producing no emissions during operation
Low Operating Costs: Once wind turbines are installed, their operational and maintenance costs are relatively low compared to fossil fuel power plants
Scalable: Wind energy can be harnessed at different scales, from small individual turbines to large wind farms

Wind Energy: Negative Impacts

Intermittent and Unpredictable: Wind energy depends on wind patterns, which are variable
Visual and Noise Pollution: Wind turbines can be considered unsightly, and their noise can disturb nearby residents
High Initial Costs: Building wind turbines requires significant capital investment, especially for offshore wind farms

Geothermal Energy: Positive Impacts

Reliable and Consistent: Geothermal energy provides a stable and continuous source of energy
Low Emissions: Geothermal power plants emit very low amounts of greenhouse gases compared to fossil fuel plants
Small Land Footprint: Geothermal plants typically require less land area than other renewable energy sources like solar or wind

Geothermal Energy: Negative Impacts

Location-Specific: Geothermal energy can only be harnessed in specific regions with active geothermal activity
Risk of Earthquakes: The extraction of geothermal energy can cause small seismic events or earthquakes
High Upfront Costs: Drilling deep into the Earth's surface to access geothermal energy is costly and requires advanced technology

Biomass Energy: Positive Impacts

Carbon Neutral: Often considered carbon neutral because the CO₂ released during combustion is offset by the carbon absorbed by the plants during their growth
Waste Reduction: Can use agricultural, industrial, or municipal waste as fuel, reducing the amount of waste that goes to landfills
Renewable Resource: Biomass is a renewable resource, as plants and organic waste materials can be continually replenished

Biomass Energy: Negative Impacts

Air Pollution: Burning biomass can release particulate matter, carbon monoxide (CO), and other pollutants
Land Use and Deforestation: Growing crops specifically for biomass energy can compete with food production and lead to deforestation

Oil Pollution

Oil pollution occurs when oil spills into the environment, often through accidents during oil drilling, transportation, or storage.
Oil spills contaminate water bodies, coasts, and wetlands, with long-lasting environmental and economic impacts.

Major Oil Spills

Deepwater Horizon Oil Spill (2010) - Gulf of Mexico: The Deepwater Horizon drilling rig explosion caused the largest marine oil spill in history. Around 4.9 million barrels of oil were released.
Exxon Valdez Oil Spill (1989) - Alaska: The Exxon Valdez oil tanker ran aground off the coast of Alaska, spilling about 11 million gallons of crude oil.

Oil Pollution Risk Due to Company Operations

Oil pollution risks arise at several stages in the oil production and supply chain, including drilling, transportation, and refining.
These operations present opportunities for accidents, leaks, or spills, each with potential environmental consequences.

Oil Spills During Drilling

Offshore Drilling: Platforms situated far out in the ocean are susceptible to accidents like blowouts (as seen in the Deepwater Horizon disaster)
Blowouts: Occur when the pressure inside an oil well is not properly controlled, causing an uncontrolled release of oil and gas
Subsea Leaks: Pipelines and drilling systems under the seabed can corrode or rupture, leading to slow, undetected leaks

Oil Spills During Transportation

Oil Tankers: Large oil tankers are susceptible to accidents, including collisions, groundings, and hull breaches.
Pipeline Leaks: Oil pipelines can rupture due to corrosion, poor maintenance, or natural disasters.
Transfer Operations: When oil is transferred between ships, pipelines, or storage tanks, mishandling or faulty equipment can lead to spills.

Oil Spills During Refining

Accidental Leaks: At refineries, where crude oil is processed, equipment failures, corrosion, or human error can cause accidental oil spills or leaks.
Chemical Contaminants: Oil spills in refineries can contaminate local soil, groundwater, and nearby bodies of water with not just oil but also toxic byproducts from the refining process.
Storage Tanks: Large storage tanks at refineries can develop leaks, especially if they are old or poorly maintained.

Management of Oil Spills

Oil spill response strategies include containment, cleanup, and restoration measures.
