Introduction to Environmental Systems: Energy Resources

Flashcards covering key vocabulary related to energy resources and environmental impacts discussed in the lecture.

Fossil Fuels

Natural substances formed from decomposed plants and animals, used as energy sources; includes oil, natural gas, and coal.

Nonrenewable Energy

Energy resources that cannot be replenished in a short timeframe; includes fossil fuels.

OPEC

Heavy Oil

Thicker than conventional crude oil, found in deposits and has a lower net energy yield.

Fracking

A method of extracting oil and natural gas from shale rock through hydraulic fracturing.

Coal

A solid fossil fuel formed from decaying organic matter, known for causing significant environmental pollution.

Nuclear Power

Energy produced through nuclear fission, known for low environmental impact and low accident risk but limited by public fear.

Renewable Energy

Energy sources that are replenishable and sustainable, such as solar, wind, and hydro power.

Methane

A potent greenhouse gas that is a significant component of natural gas, contributing to climate change when leaked.

Greenhouse Gases

Gases that trap heat in the atmosphere, contributing to global warming and climate change.
