energy resources = natural resources used for generating power
major energy resources
coal
natural gas
oil
nuclear power
fuelwood
biofuel
solar power
wind power
hydroelectric power
tidal power
wave power
geothermal power
non-renewable energy: coal, natural gas, oil, nuclear power
nuclear power is produced by the nuclear reaction of radioactive elements like uranium and plutonium
fuelwood is wood cut from trees
biofuel is produced from plant and animal products or waste
solar power is converted from sunlight
wind power is generated when wind blows
hydroelectric power is produced by water falling from a great height
tidal power is produced by changing level of tides
wave power is converted from the energy of sea waves
geothermal power is produced by the intense heat from the molten rock beneath the earth's crust
the most widely used energy resources in the world: oil, coal, and natural gas (they are known as fossil fuels)
fossil fuels take up 85% of energy consumption in the world
fossil fuels are formed underground from the remains of dead plants and animals from millions of years ago
fossil fuels have different forms and colours but they are formed in the same way
fossil fuels are widely used because
coal is cheap to mine and the drilling techniques of oil and natural gas are mature
they produce much energy and are convenient to use
they are cheap to transport
the global distribution of fossil fuels is uneven
coal is mainly found in the Asia Pacific region, Russia and the USA
oil and natural gas are heavily concentrated in the Middle East region, Russia and North America
Iran and Saudi Arabia in the Middle East are rich in oil and natural gas
Iraq in the Middle East is rich in oil
Turkmonistan in the Middle East is rich in natural gas
balance = production - consumption
(+) surplus: production>consumption
(-) deficit: production<consumption
reasons to scramble for energy resources:
The mismatch of energy-producing countries and energy-consuming countries
Insufficient fossil fuel reserves to meet future demand
some major energy producers produce more fossil fuels than they need (eg Russia and Saudi Arabia) while some major energy consumers do not produce enough fossil fuels to meet their demand (eg China and India)
thus, there is mismatch of energy-producing countries and energy-consuming countries
the majorenergy consumers that do not produce enough fossil fuels (eg China and India) have to look for a reliable fuel supply
look for a reliable fuel supply by:
maintaingood relationships with the energy-exporting countries
invest in the energy industry in energy-exporting countries
invest in building pipelines and shipping facilities to ensure smooth transport of fuels
develop their own alternative energy resources (eg solar power)
LDCs (eg China and India) have rapidindustrial and economic development, rapid population growth, and a rise in living standards
MDCs (eg USA) have high levels of industrial and economic development, and have high living standards
Thus, lead to a large and increasingglobal demand for fossil fuels
it is hard to meet the increasing demand because
fossil fuels are finite resources with limited supply
difficult to extract new fossil fuel reserves because it is expensive and risky to the environment (eg new oil reserves found in deep seas in the Arctic)
problems caused by the shortages of fossil fuels
economic problems
conflicts among countries
shortage of oil causes negative economic impact as with the shortage of oil, oil price increases, transport and industrial production costs rise, thus slowing down economic growth or even leading to global economic recession
countries may engage in wars to secure a reliable supply of oil and natural gas because of the shortage of oil and the importance of oil and natural gas supply to economic development
