What are the problems caused by the uneven distribution of power resources in China?
What are the problems caused by the uneven distribution of power resources in China?
The cost of the transport of fuels from the western
region to the eastern and
southern regions is very high
because of poor communication. This makes the supply of power uneconomical.

What are the problems arising from the consumption of power in China?
Mining in Gobi
Non-renewable power resources
All fossil fuels are non-renewable power resources because their reserves will decrease and be exhausted eventually.
Unit 12 What are China’s power problems?
China should plan carefully the mining of these fuels so these power resources will still be available to our children.

The Three Gorges Project
Power production in China cannot
keep pace with the
increase in demand.
Unit 12 What are China’s power problems?
Rapid increase in power consumption
The demand for energy in China has been increasing rapidly because of strong economic growth.

China is exporting a lot of coal but it is also importing coal from other countries.
If this trend continues, very soon China’s coal imports will be more than her exports.

Is the problem of insufficient power resources the same everywhere in China? Power shortage in southern provinces
China’s southern provinces are basically poor in power resources yet the demand is great and is increasing rapidly.
Power blackouts are frequent.
Power shortage has become a serious problem in the southern provinces, this affects the economic development of the region.

Non-renewable power resourcesNon-renewable power resources (非再非再生能源生能源 )--power resources such as coal, oil and natural gas, which are fossil fuels, can be used up one day as they cannot be recovered or recycled fast enough to meet consumption.
