Examine the future of nuclear energy in a carbon-constrained economy.
Nuclear power has been promoted viciously as a source of energy that emits zero carbon. It does contribute to carbon emissions indirectly through associated sources. In addition, renewable energy sources are better placed to replace fossil fuel energy.
Carbon emissions in nuclear power
- Construction emissions
The construction and demolition of nuclear power plants emits large amounts of carbon into the atmosphere. This makes it party to carbon emission.
- Fuel mining and storage
Nuclear fuel mining process emits large amount of carbon during transportation phase. In addition, strict rules for used fuel storage also have a role in carbon emission.
Benefits compared to conventional fuels
- Low emission during main process
The emission of carbon during actual energy generation is very low in comparison to conventional sources such as coal, natural gas and biogas plants.
- Energy density
The amount of energy produced from a unit of fuel is higher in nuclear power. This makes it more efficient in comparison to fossil fuels.
Other concerns of nuclear energy
- Safety
The nuclear energy needs to be undertaken in strict environment for the sake of safety. Any leakage of radiation can be detrimental to human lives.
- High cost
The cost of setting up a nuclear power plant is very high. This is because of the strict safety standards, the cost of fuel and also additional security.
- Long duration of commission
The process of identifying location, construction of plant, commission of plant etc takes a long duration of about 12-15 years. This discourages its widespread use.
Thus, nuclear power is indeed a good alternative to fossil fuels but cost wise, solar energy and wind energy are more feasible for the global economy.
