Two main issues with fossil fuels
1. Climate change: Burning coal, oil and natural gas releases large amounts of CO2 (and some methane and N2O), the main drivers of human-caused global warming.
2. Local pollution and environmental harm: Extraction and combustion produce particulate matter, NOx, SO2, toxic runoff and habitat damage that harm human health and ecosystems; extraction also causes spills, subsidence and water contamination.
Advantages and disadvantages of using fossil fuels to generate electricity
Advantages
- High energy density and reliable dispatchability (can run on demand, provide baseload and quick ramping).
- Well-developed, existing infrastructure and supply chains.
- Relatively low upfront capital for some fossil plants (especially when using existing plants) and established technology.
- Historically competitive fuel costs (varies by region and fuel).
Disadvantages
- High greenhouse gas emissions (especially coal) contributing to climate change.
- Air pollution (particulate matter, SOx, NOx) with associated health impacts.
- Environmental damage from mining/drilling, water use and thermal pollution.
- Finite resource with price volatility and geopolitical risks.
- Unpriced externalities (health and climate costs) not reflected in market price; increasing regulatory and carbon-policy risk.
- For natural gas specifically: methane leakage during production/transport can undercut its climate advantage.
Four uses of energy in the United States (end‑use sectors) — approximate shares
(Recent U.S. Energy Information Administration data; rounded and year-dependent)
- Transportation: ~28–29%
- Industrial: ~22–24%
- Residential: ~11–12%
- Commercial: ~10–12%
If you want exact, up-to-date percentages for a specific year (or a chart showing trends over time), I can pull the EIA figures and cite them.
