Insufficient diversification of urban and industrial energy supply

No single energy source can continue to meet all energy needs over a long period, nor are there new sources capable of taking over fully from those which now exist. In addition, increased reliance on certain types of energy resources (for example, coal and nuclear energy) result in environmental problems.

1. Lack of integrated energy resource management
2. Insufficient diversification in energy research
3. Insufficient diversification
4. Energy dependence and vulnerability

1. Energy crisis

1. Unexplored energy alternatives
2. Insufficient energy equipment
3. Inadequate governmental energy conservation policies

1. Envisioning future energy scenarios
