Energy Security: The importance of strategic Mix with NUCLEAR

Energy security is:

From the demand side i.e. the consumers: to have energy/electricity at all time. they demand that whenever they switch on the plug, electricity will flow.

From the supply side: to be able to supply electricity at all time to all consumers.

How?
In order to be able to supply electricity, fuel is needed to generate electricity.

Gas/Coal/Oil/Biofuel is burnt to boil water then to produce steam that moves the turbines. The moving turbine will produce electricity through electromagnetic conversion. Think of dynamo, dynamo can be found usually in bike with lamp. You will cycle the wheel, the bike will move while moving the rotor in dynamo which will produce electricity to light up the lamp.

Similarly, wind turbine need wind to move the turbine that produces electricity, while hydro need water to move the turbine.

In a nuclear power plant, the nuclear reaction will produce heat that will boil the water to produce steam which will then move the turbine.

In a nutshell, many sources of electricity uses turbine to generate electricity.

It is different with solar power panel, which need the sunlight to initiate reaction within the semiconductor that will produce electricity without the need of turbine.

However, let's move back to the main topic. ENERGY SECURITY.

In general, you need something to produce electricity. You cannot rely on just one source of electricity generation. What if that one source of electricity is not available?

Most fuels need to be replenish at once when there are burnt. Coal needed to be supplied constantly in order for the power plant to continue producing electricity. Similarly, gas, oil, biofuels, water, wind and sunshine need to be available at all time if you want to produce electricity at all time. But we know that would not happen at all time. Sun will not shine at night or when it is raining or when it is cloudy. Wind will not blow at all time. Gas would not available if there is problem at gas terminal or at the gas pipelines. Coal will not be available if there problems at the mines or if the ship that delivers coal does not arrive. Oil cannot be delivered without using road tankers or ship tankers.

What about nuclear power plant? The fuel that it uses can last for 18 to 24 months without replenishment. Thus, once you put the fuel in day 1, you can be rest assured that power/electricity will continue to be generated for 18 months or until day 540 or longer depending on the design.

This is energy security! with nuclear as part of the energy mix!

Trust me, that gas/coal/oil that we have today are subjected to constant supply, without which, there will not be constant supply of electricity.
