ENERGY SECURITY
It is generally evaluated at a national level, countries are either energy secure or insecure.
● There are four aspects of supply: Availability, Accessibility, Affordability and Reliability
-
● Those countries that are most energy secure are those who can meet their energy demand using supply from within their boundaries.

LONG TERM mainly deals with timely investments to supply in energy sources that will match economic developments and environmental needs
SHORT TERM focuses on the ability of the energy system to react promptly to sudden changed in the balance between energy demand and energy supply.
GOOD QUALITY
consistent and secure and can be relied upon year round. There is unlikely to be any geopolitical problems and there is little risk from changing climatic conditions or natural hazards. A good quality energy supply involves different sources which contribute to the energy mix.
ENERGY INTENSITY
Energy Intensity is an alternative measure of how efficiently a country is using its energy, in units of energy used per unit of GDP. A high energy intensity indicates a high price or cost of converting energy into GDP. It is generally recognised that energy intensity decreases with development; energy is used more efficiently and so the cost per unit of GDP reduces.
GLOBAL ENERGY MIX
dominated by fossil fuels . Primary energy sources produce energy by using a raw material
SECONDARY SOURCES
modified primary energy sources which are easier to use e.g. oil into petrol and coal into electricity.
CONSUMPTION VARIATIONS
genrally higher in northern hemisphere countries, which are more developed
