State three causes of energy crisis in today's world.
1 Answer
The causes of energy crisis are :
- unwise use of non renewable source of energy.
- rapid population growth
- urbanization and industrialization.
Over the last two centuries, energy needs have skyrocketed dramatically, especially because of the transportation and industry sectors. However, fossil fuel are polluting and their reserves are limited.In recent years, many scientists have raised their voice to warn about climate change, caused notably by the burning of oil and coal in order to produce energy.Global energy consumption is increasing and we will face a shortage of fossil fuels in the coming decades. Therefore, the availability of reserves is an important source of concern.
OVERCONSUMPTION
Our current consumption model relies almost entirely on the use of non-renewable energy sources such as oil, gas, coal and uranium. At the current rate of consumption, oil will be the first fossil fuel to run out. According to projections, there would be between 40 and 60 years of proven reserves of conventional oil. Natural gas could be exploited for another 70 years. For coal, there would be around two centuries of reserves.
OVERPOPULATION
These data are to be put into perspective because they are based on current consumption, while it is clear that it will increase considerably. Energy demands are and will be amplified by the demographic - the world’s population should reach nearly 10 billion people in 2050 - and economic boom of growing areas. According to the International Energy Agency (IEA), global energy demand could increase by more than 50% by 2030 in the absence of public policies in this area.
ENERGY WASTE
Mainly coming from the unnecessary use of energy resources, energy waste describes the wastage of energy sources, in particular fuels and electricity. Consequently, the reduction of waste is a colossal source of energy savings, which requires actions both on an individual and collective level.
