Economic Activity and Energy Keywords



Economic sector: 
a major division of the economy based on the type of economic activity. The economies of all countries are made up of three sectors; most HICs have a fourth sector.

Energy: heat and motive power. The former provided by the sun and by burning coal, oil and timber, the latter provided by electricity, gas, steam and nuclear power

Energy consumption: the amount of energy used by individuals, groups of countries

Energy efficiency: making the most of energy sources in order to cut down on waste and reduce consumption

Energy gap: a gap created because the loss of energy caused by phasing out the use of fossil fuels is greater than the amount of energy that is being developed from new, low-carbon sources

Fossil fuel: carbon fuels such as coal, oil and natural gas that cannot be ‘remade/renewed’, because it will take tens of millions of years for them to form again

Global shift: the movement of manufacturing from HICs to cheaper production locations in LICs

High-tech industry: economic activities that rely on advanced scientific research and produce new, innovative and technologically advanced products, such as microchips, new medical drugs and new materials

Informal employment: types of work that are not officially recognized and are taken up by people working for themselves on the streets of LIC cities. e.g. shoe shining, selling stuff on the street

Non-renewable energy: energy produced from resources that cannot be replaced once they are used. Examples include the fossil fuels of coal, oil and natural gas

Primary sector: economic activities concerned with the working of natural resources-agriculture, fishing, mining and quarrying

Quaternary sector: economic activities that provide highly skilled services such as collecting and processing information, research and development

Secondary sector: economic activities concerned with making things, such as cars, buildings and electricity

Renewable energy: sources of energy which cannot be exhausted, such as the sun, wind and running water

Tertiary sector: activities that provide a wide range of services and enable goods to be traded

Transnational company (TNC): a large company operating in a number of countries and often involved in a variety of economic activities
