Energy resources

Per Capita energy consumption

the average energy consumed per person

primary industry

agriculture, mining, raw material extraction

high economic output

secondary industry

heavy manufacturing industry (metal smelting, chemical industry)

light manufacturing industry (car assembly)

high economic output

tertiary industry

provides goods and services to people and businesses

low energy use per economic output

quaternary industry

information and IT

very low energy use per economic output unit

how do climatic conditions affect energy usage?

cold winters - more heating

hot areas - more AC

high winds - increased heat losses

sunny weather - increases passive solar gain

domestic energy uses

space heating, lighting, running appliances

energy uses in agriculture/fisheries

fuel for machinery, manufacture of chemicals, food processing, storage

energy uses in other industries

machinery, heating, chemical reactions, water treatment

energy uses for transport

goods transport

people transport

locational factors - solar

high light intensity, low cloud cover

locational factors - wind

shallow seas, open plains, upland areas

avoid areas of high ecological sensitivity, urban areas, and scenic areas

locational factors - HEP

high reliable rainfall, small dam and reservoir basin, large catchment are, impermeable bedrock, stable geology

locational factors - biofuels

farmland for crop/livestock waste and biofuel crops

urban areas for food waste, sewage

locational factors - geothermal

hot rocks near ground surface, recent volcanic activity

locational factors - tidal

large tidal range, focused tidal flow, increased flow velocity

energy density

amount of energy in a given mass of a energy resource

why is a high energy density useful?

smaller quantities needed, easier storage and transport

easier to reach high temperatures

energy resources with high energy density

nuclear fusion and fission

hydrogen

fossil fuels

energy resources with low energy density

wind and solar

define resource availability

potential contribution of a resource to energy supplies

how does the government influence energy use?

financial grants

guaranteed price for energy produced

less strict planning regulations

permission to develop favourable sites

compensation for affected communities
