What are the two biggest challenges facing energy in today's world?

• Running out of fossil fuels

• Environmental impacts of our energy choices

• Nuclear radiation

• Energy access and affordability

• Energy cartels that control energy markets

Which paraphrase below best describes the point of the "Wedges Game" (by Pacala and Socolow)?

• "Energy can be a divisive topic, and this results in 'wedge' issues that cause conflicts in modern society."

• "A wedge is considered a simple machine in physics, so appropriate use of wedges can improve our

  effective use of energy."

• "There are several existing ways we can reduce our carbon emissions, so we can choose different

  combinations of these to meet our carbon reduction targets."

• "The Russian invasion of Ukraine began a geopolitical strategy 'game' by countries to replace Russian oil

  and gas."

In recent decades, there has been great progress in providing electricity to people. However, one part of

the world still has a lot of people without access. Which part of the world has the most people still lacking

access to electricity?

• Amazon jungle

• Sub-saharan Africa

• Southeast Asia

• India

• China

After Russia's invasion of Ukraine in 2022 and Russia's threats to cut off energy supplies to Europe, Europe

tried to import LNG (Liquified Natural Gas) by ship instead. What was one of the major challenges in this

approach?

• Lack of infrastructure to import LNG

• Unwillingness of countries to ship LNG to Europe

• Russian threats against LNG shipping countries

• High prices of LNG

• Environmental protests against natural gas

Nobel prize winner Richard Smalley gave a list of humanity's top ten problems for the next 50 years. At the

top of his list was "Energy". Why was "energy" listed at the top of his list?

• The list is alphabetical, and "energy" was alphabetically first

• Richard Smalley is from Texas which is energy-rich with oil, so of course energy is most important

• The list is from the perspective of only developed countries, so food and water weren't considered

• Enough energy solves the other problems on the list

What is the relationship between power and energy?

• Energy = Power * distance

• Power = Energy * distance

• Power = Energy / time

• Energy = Power / time

What does HDI stand for?

• Human Development Index, a measure of human wellbeing used by the United Nations

• Healthy Diesel Initiative, a European effort to promote clean diesel

• Health Data Institute, a government agency that reports on health effects of energy sources

• "Help Do It", a slogan of climate activists at the Paris Climate Accords

• Initials for a Chinese firm that operates the world's largest coal mines

Which statement best defines "energy intensity" for a country?

• The average amount of energy used per person

• A measure of the amount of a country's estimated fossil fuel energy resources (coal, oil, natural

  gas)

• The amount of energy used by the country divided by its gross domestic product

• The available wind and solar in the country

For developed countries (like the US, Japan, France, etc.), which statement below best describes the

expected trend in energy use in the future.

• Developed countries are expected to see large growth in energy use

• Developed countries are expected to see flat or small growth in energy use

• Developed countries are expected to see flat or small declines in energy use

• Developed countries are expected to see large declines in energy use

Which of the answers below corresponds to the definition of "efficiency of energy conversion"

• Power in / useful energy out

• Useful power out / energy in

• Useful energy out / energy in

• Energy in / useful energy out

• The cost of retail gasoline vs. the market price of the same amount of crude oil
