Conventional Energy Flashcards
What are the basics of energy consumption in the US?
Fossil Fuels
Renewables
Natural Gas
Coal
Oil
What energy sources are increasing?
renewable energy
while the overall usage of fossil fuels like coal, oil, and natural gas is still dominant but with a slower growth rate; in some regions, like the United States, natural gas consumption has shown a noticeable increase
What do all fossil fuels have in common?
they are non-renewable energy sources
They are primarily composed of carbon and are formed from the decomposed remains of ancient organic matter, like plants and animals
How are fossil fuels different from one another?
primarily in their physical state
formed slightly different due to organic matter composition, the amount of time the fuel remains buried, and the temperature and pressure conditions of the geographic region
How are fossil fuels formed?
when the remains of ancient plants and animals, primarily from millions of years ago, are buried under layers of sediment and subjected to intense heat and pressure over time, causing the organic matter to decompose and transform into substances like coal, oil, and natural gas
What sector is coal predominantly used for?
power sector
What sector is oil predominantly used for?
transportation sector
What sector is natural gas predominantly used for?
electric power generation sector,
What energy sources are decreasing
coal
pro and con of coal
pro - cheap, easy & safe movement, lack of conflict, energy rich
Con - non renewable, pollution, biodiversity loss
pro and con of natural gas
Pro - least polluting, versatile, decent amount in usa
Con - releases methane, earthquakes
pro and con of oil
Pro - transportation, makes plastics
Con - plastic pollution, political conflict, not easy to transport, oil spills, flammable
how to access coal
mining it from the ground
how to access natural gas
fracking
how to access oil
fracking, drilling (A well is drilled into the reservoir)
cons of accessing coal
Greenhouse gas emissions
Air pollution
Habitat destruction
Water quality degradation
Climate change
cons of accessing natural gas
methane leaks
Greenhouse Gas Emissions
Air and Water Pollution (fraking)
Water Contamination
Land Degradation
Ecosystem Disturbance
cons of accessing oil
Oil Spills
Air and Water Pollution
Toxic Emissions
Greenhouse Gas Emissions
Methane Leaks
Land Degradation
Water Contamination
Exposure to Hazardous Chemicals
How is electricity generated?
using the force of a moving fluid (like wind, water, or steam) pushes the blades, causing them to spin and turn a generator that produces electricity.
how much oil is left
40-50 years
how much coal is left
100-150 years
how much natural gas is left
50-60 years
What is energy?
the ability to do work
What is a fossil fuel?
non-renewable energy sources originating from decomposing plants and animals
When fossil fuels are burned, they release carbon dioxide , methane, nitrous oxide and other pollutants into the atmosphere. These emissions contribute to climate change, air pollution, and water pollution
