Energy Resources Flashcard 1

Front

What is primary recovery in petroleum extraction?

Back

Primary recovery is the initial stage of oil extraction that relies on underground pressure to drive petroleum to the surface.

Front

What are the environmental consequences of oil spills?

Back

Oil spills can lead to environmental hazards, including harm to marine life, pollution of water bodies, and damage to ecosystems.

Front

Which energy source is commonly used for heating and cooking?

Back

Natural gas is primarily used for heating and cooking due to its efficiency and availability.

Front

What is a renewable energy source?

Back

A renewable energy source is one that can be replenished naturally over time, such as hydroelectric power, solar energy, and wind energy.

Front

What materials are used in hydraulic fracturing?

Back

Hydraulic fracturing uses water, sand, and chemicals to extract oil and gas from underground rock formations.

Front

What is secondary recovery in oil extraction?

Back

Secondary recovery involves techniques that enhance oil recovery after primary recovery, often using water or gas injection to increase pressure.

Front

What is enhanced recovery in petroleum extraction?

Back

Enhanced recovery refers to advanced techniques used to extract more oil from a reservoir, such as thermal recovery or chemical injection.

Front

What is the impact of coal on the environment?

Back

Coal mining and burning can lead to air pollution, greenhouse gas emissions, and environmental degradation.

Front

What is the role of natural gas in energy production?

Back

Natural gas is a cleaner-burning fossil fuel used for electricity generation, heating, and as a feedstock for various chemicals.

Front

What are the advantages of hydroelectric power?

Back

Hydroelectric power is renewable, produces no direct emissions, and can provide a stable and reliable energy supply.
