A high contributor to the global economy means that a resource contributes more than 20% of global energy use or more than $⁢400 billion in annual export value. A low contributor means that a resource contributes less than 20% of global energy use and less than $⁢400 billion in annual export value. Determine whether each fuel is a high or low contributor.

Why does oil contribute more to global economic development than peat, even though both are nonrenewable fuels?

A
Oil reserves are smaller than peat reserves, so it is more sustainable long-term.
B
Peat is a fossil fuel, while oil is considered renewable on human timescales.
C
Oil has much higher production and export value, making it central to trade and transportation.
D
Peat burns more cleanly than oil, so it is mostly used in modern industries.
3

Which fuel has the greatest overall economic influence on the global market?

A
oil
B
coal
C
natural gas
D
peat
4

What inference can be made about the relationship between nonrenewable energy resources and global development?

A
Fuels with the fastest formation time are the most important for economic growth.
B
Fuels with the highest export value tend to have the largest impact on international economies.
C
All nonrenewable resources contribute equally to global trade and development.
D
Peat is the most valuable nonrenewable resource because it is widely distributed.
5

Why might natural gas play a growing role in supporting both energy systems and economic development?

A
It is fully renewable and does not release carbon dioxide when burned.
B
It is widely distributed, inexpensive to extract, and forms in just a few decades.
C
It has relatively low carbon emissions compared to coal and oil, and its export value is significant.
D
It replaces renewable energy sources such as wind and solar because it is cleaner.
6

What pattern emerges when comparing the fuels' reserves to their annual export values?

A
Fuels with faster formation times are always the most valuable because they can be replenished in a short time.
B
Export value depends not just on reserves but also on global demand and infrastructure.
C
Fuels with smaller reserves always have higher export values because supply drives demand.
D
Fuels with smaller reserves are never economically important because demand is too low for limited supplies.
7

Why might nations with large coal reserves still face economic challenges compared to oil-exporting nations?

A
Coal is a nonrenewable resource, so its export potential is limited to existing reserves.
B
Coal exports have a much lower value than oil exports, limiting revenue growth.
C
Coal reserves are too small to meet global energy demand.
D
Oil is used only for electricity, while coal powers all modern transportation.
8

Why do fossil fuels like natural gas and crude oil have higher energy densities than peat?

A
Peat releases less energy because it is burned in smaller stoves.
B
Fossil fuels formed under greater pressure and heat, concentrating their stored energy.
C
Fossil fuels are renewable, so they continually produce new energy.
D
Fossil fuels are made from modern plants, which naturally produce more energy than ancient plants.
