ANAYZLIZING COMMON ENERGY SOURCES
WHAT ARE NON-RENEWABLE RESOURCES?
Definition: Non-renewable energy comes from sources that cannot be replenished in a short period of time.
Types:
Fossil Fuels: Includes coal, oil, and natural gas.
Nuclear Energy: Derived from nuclear reactions, primarily using uranium.
Characteristics:
Finite Supply: Limited resources that will eventually deplete.
High Energy Density: These resources provide a large amount of energy per unit.
Environmental Impact:
Pollution: Burning fossil fuels releases greenhouse gases and pollutants.
Habitat Destruction: Extraction processes can damage ecosystems.
FOSSIL FUELS
Mining and Drilling: Fossil fuels are extracted through:
Mining (for coal)
Drilling (for oil and natural gas)
Types:
Coal: A solid fossil fuel used primarily for electricity generation and steel production.
Oil: A liquid fossil fuel used mainly for transportation fuels (gasoline, diesel) and in production of plastics and chemicals.
Natural Gas: A gaseous fossil fuel used for heating, electricity generation, and as an industrial feedstock.
Formation: Created through decomposition of organic matter under high pressure and temperature over geological time scales.
DISTRIBUTION OF FOSSIL FUELS
Top Producers: USA leads in production of oil and natural gas.
ADVANTAGES AND DISADVANTAGES OF FOSSIL FUELS
Advantages:
High Energy Density: Efficient energy source providing large energy output per unit.
Reliability: Continuous energy production, unlike some renewable sources dependent on weather.
Infrastructure: Existing infrastructure for extraction, transportation, and utilization.
Economic Benefits: Often cheaper to extract and use compared to renewables.
Versatility: Applications in electricity generation, transportation, industrial processes.
Disadvantages:
Environmental Impact: Contributes to climate change and air pollution.
Finite Resources: Non-renewable, will eventually deplete.
Habitat Destruction: Ecosystem and wildlife habitat damage from extraction.
Health Risks: Air pollution impacts respiratory and cardiovascular health.
Market Volatility: Price instability due to geopolitical factors.
LOOKING AT NATURAL GAS
Advantages of Natural Gas:
Cleaner Burning: Produces fewer pollutants and greenhouse gases than coal and oil.
Abundant Supply: Large reserves, particularly in the U.S.
Efficient: High energy content with efficient combustion.
Versatile: Used for various applications (electricity, heating, cooking, industrial).
Lower Cost: Generally cheaper than other fossil fuels and some renewables.
Infrastructure: Established infrastructure for extraction and distribution.
Disadvantages of Natural Gas:
Greenhouse Gas Emissions: Emits CO₂ and methane, contributing to climate change.
Non-Renewable: Finite resource that will eventually run out.
Extraction Impact: Hydraulic fracturing (fracking) can cause water contamination and earthquakes.
Transportation Risks: Risks associated with pipeline leaks and explosions.
Market Volatility: Prices can change based on geopolitical and economic factors.
WHAT IS THE DEAL WITH FRACKING?
ADVANTAGES AND DISADVANTAGES OF FRACKING
Advantages of Fracking:
Increased Energy Access: Extraction from previously hard-to-reach deposits.
Economic Benefits: Job creation and revenue generation in local economies.
Energy Independence: Reduces reliance on imported energy.
Lower Energy Prices: Increased supply can lower consumer energy costs.
Cleaner than Coal: Burns cleaner than coal with fewer pollutants.
Disadvantages of Fracking:
Environmental Impact: Potential groundwater and surface water contamination.
Seismic Activity: Inducing earthquakes through high-pressure fluid injection.
Methane Emissions: Significant release of methane, a potent greenhouse gas.
Water Usage: High demand for water, straining local resources.
Health Risks: Exposure to harmful chemicals in fracking operations.
