EGS resource base is defined as the total thermal energy in place in the earth’s crust to the depth that we can reach with current technology

A country’s ability to meet its own energy needs (not necessarily 100% thereof) from domestic sources, or by investments made by national companies in O&G fields abroad to develop fields for their own consumption, in order to provide primary energy for all of their electricity needs

The overall framework by which a country secures its energy supplies is often discussed under the heading of “energy security”. The concept of energy security is usually interpreted in terms of diversification of supply sources from a variety of power and fuel markets in order to reduce dependency on one or more suppliers and/or supply routes and exposure to their market power. This concept of “energy security” is generic to any country faced with uncertain energy markets and complex regional supply options. An important strategic issue for countries to meet their energy demand is the trade-off between security of supply and cost of supply. In principle, greater security implies higher cost, and in practice the challenge is to find a trade-off that provides an acceptable degree of security at an affordable level of cost. Energy security can be defined as an uninterruptible supply of energy, in terms of quantities required to meet demand at affordable prices. The concept first appeared on the scene during the oil crisis of the 1970s, although during the first World War Winston Churchill had already formulated the fundamental principle of energy security when he stated that “safety and certainty in oil lie in variety and variety alone”. Energy security is aptly defined as “access to supplies at a cost which enables investment by suppliers but does not damage the consumers or the environment”. It is also about diversity of suppliers, of supply and of infrastructure so that one is never dependent on one source or on one pipeline, since such over-dependence does not amount to security. Energy security is always a local aspect and each country has its own particular system and conditions

Relates to Israel’s geopolitical situation which makes it virtually impossible for the country to import electricity or receive backup from a neighboring country and thus requires a policy an energy policy that will take this into consideration

External, such as in the exogenous costs that influence the electricity tariff, such as planning delays, changes in foreign currency exchange, etc.

Variables which are determined outside the system under consideration. They may be political, social, environmental, etc.
