The past few years have seen momentous shifts in the production of fossil fuels and the use of renewable and other energy sources. Here are 25 questions to test your knowledge of what's happening in the energy world.

Which country is most responsible for the global rise in energy consumption?

Saudi Arabia

 

Russia

 

China

 

India

 

When is China expected to overtake the US as the largest generator of power?

It already has

 

2015

 

2022

 

2031

 

Consumption of which fossil fuel will grow the fastest worldwide through 2030?

Oil

 

Natural gas

 

Coal

 

Which nonfossil fuel will see the fastest growth in worldwide consumption through 2030?

Nuclear

 

Hydroelectric

 

Wind, solar, and other renewables

 

Which power source grew so much in 2011 that for the first time it generated more than half of the world's renewable power?

Geothermal

 

Solar

 

Wind

 

What's the difference between a nation's reserves and resources of conventional energy?

Reserves are the hydrocarbon energy already produced; resources are the accumulations still underground.

 

Reserves are the hydrocarbons that a nation possesses; resources include alternative energy sources, such as wind and solar.

 

Reserves are the energy a nation expects to recover from known accumulations; resources include accumulations it could conceivably discover and recover.

 

There is no difference. They're the same thing.
