Risks for the longterm energy supply

The continuous growth in demand raises the question of the availability of energy in the long term, in sufficient quantities to avoid a major crisis,

bearing in mind that most of the energy comes from resources which, by definition, are limited. As already mentioned in the previous chapter, energy supplies currently rely mainly on fossil fuels, which represent slightly over 80% of the primary energy consumed worldwide. According to the IEA reference scenario, this proportion is expected to remain stable until 2030 (Figure 2.2). It is true that fossil energy resources will not be depleted in the short term. If consumption continues at the current rate, the proven reserves represent about 40 years for oil, 64 years for natural gas and almost 150 years for coal [8, 84, 86].

Uncertainties nevertheless affect the energy supplies, oil in particular. Reserves are being consumed faster than they are renewed: currently, only one-third of the proven reserves consumed on a global scale is renewed every year. Oil production will therefore inevitably reach a ceiling before starting to decline. This point is examined in more detail in Chapter 7.

Emergency Preparedness

Emergency Preparedness

Remember to prepare for everyone in the home. When you are putting together a plan to prepare in the case of an emergency, it is very important to remember to plan for not only yourself and your children, but also for your family pets and any guests who could potentially be with you at the time of the emergency.
