Define a country's energy mix .

A country's energy mix is the combination of energy sources it uses, which depends on factors such as the availability of fossil fuels, sunlight, rivers, wind and coastal access.

Define renewable energy .

Renewable energy comes from sources that are infinite and will not run out , such as hydroelectric, wind, solar, wave/tidal, geothermal and biomass.

Which renewable energy source still produces greenhouse gas emissions once in use?

Biomass/waste — unlike other renewables, it emits greenhouse gases when used.

Give two environmental reasons for reducing the use of fossil fuels.

Burning them releases greenhouse gases and sulphur dioxide (causing acid rain), and mining or drilling can destroy habitats .

Over ______ of the world's energy is provided by fossil fuels — coal, oil and gas.

Over 80% of the world's energy is provided by fossil fuels — coal, oil and gas.

What share of world energy comes from oil, coal and gas respectively?

Oil 33% , coal 27% and gas 24% .

Why are fossil fuels classed as non-renewable ?

They are formed from the remains of living organisms and cannot be replaced at a speed that keeps up with consumption ; gas and oil may run out by 2080.

True or False? Fossil fuels are expected to make up less than half of the world's energy by 2040.

False. Fossil fuels are expected to still provide over 75% of the world's energy by 2040.

Why does nuclear fuel, though non-renewable, not risk running out soon?

It can be reused and is used in small amounts , so it is unlikely to run out in the near future.

There are ______ active nuclear reactors across the world, most concentrated in just five countries.

There are 439 active nuclear reactors across the world, most concentrated in just five countries.

Roughly how many people rely on fuelwood for heating and cooking, and why?

Between 2 and 3 billion people, usually because they do not have access to other forms of energy .

Why can fuelwood be either renewable or non-renewable?

It is renewable if new trees are planted to replace those used, but non-renewable if the trees are not replaced .
