Physical Science HW 3/27/24 Fossil Fuels

How much electricity does the world consume annually?

• Less than 5,000 terawatt hours

• Approximately 50,000 terawatt hours

• About 10,000 terawatt hours

• More than 22,000 terawatt hours

What percentage of greenhouse gas emissions is attributed to electricity generation?

• Nearly half

• A little over a quarter

• About 25%

• Just under 10%

Which renewable energy source uses photovoltaic panels?

• Solar power

• Nuclear power

• Hydroelectric power

• Wind power

Why can't wind and solar power completely replace fossil fuels according to scientists?

• They are too expensive

• They require too much space

• They are not renewable

• They generate too much carbon dioxide

What is a major challenge of relying solely on renewable energy like solar and wind?

• High costs of maintenance

• Difficulty in finding suitable locations

• Intermittency of energy supply

• Lack of technological advancement

What percentage of the world's electricity is supplied by hydroelectric power?

• About 16%

• Less than 5%

• Nearly 25%

• Over 30%

What is the main environmental concern with hydroelectric power?

• Destruction of natural environments

• Air pollution

• Radiation leakage

• Noise pollution

What is the primary advantage of nuclear power in electricity generation?

• It is completely renewable

• It does not release carbon

• It is the cheapest option

• It requires minimal space

What does the Green Premium refer to?

• The additional cost of low-carbon technologies compared to fossil fuels

• The environmental benefit of green energy

• The premium quality of green technology

• The cost of renewable energy sources

Why is decarbonizing electricity not the sole solution to the climate crisis?

• It can lead to an increase in water usage

• It only focuses on a small part of greenhouse gas emissions

• It does not address transportation emissions

• It addresses a significant portion but not all emission sources
