Countries Increasingly Experience An Energy Gap And Therefore Seek Energy Security By Developing A Balanced Energy Mix And Sustainable Energy Use
Overview
Every country faces the same arithmetic. Demand for energy rises as population grows, as people get richer and as new technologies plug themselves in. Supply, meanwhile, depends on resources that are unevenly distributed, ageing power stations that close, and new ones that take a decade to build. When the two lines separate, the space between them is the energy gap.
This lesson explains what drives demand and supply, weighs renewable against non-renewable sources honestly rather than sentimentally, and shows how efficiency, conservation and education reduce the gap from the demand side. You will finish with two contrasting case studies of energy management, the United Kingdom and India.
Objectives
- Energy demand and production varies globally and is affected by a range of factors: population growth, increased wealth and technological advances
- Non-renewable (e.g. coal, oil, natural gas, uranium and shale gas/oil) and renewable sources of energy (e.g. solar, wind, hydroelectric power, geothermal, biomass) have advantages and disadvantages for people and the environment
- Energy can be managed in a sustainable way through education, efficiency and conservation (within industry, transport and the home)
- Case studies of energy resource management in a developed country and a developing country or an emerging country

- The energy gap is best defined as: A) the difference between renewable and non-renewable output B) the shortfall between the energy a country demands and the energy it can reliably supply C) the time taken to build a new power station D) the difference in energy use between rich and poor households Answer: B
