Repayment of principle and interest

Energy is required in the process of oil and gas production. With the discovery of the easiest fields, then energy returned on the energy invested decreases (namely the energy obtained for the amount of energy invested is less).
Thus for example, the energy returned on oil decreased from a ratio of 1 to 100 at the start of the 20th century to about 1 to 10 in those fields produced in 2012
The American geologist Hubbert established the first models to estimate peak oil in 1956 and reached the conclusion that the US would reach peak oil (without Alaska) between 1965 and 1970
Some of the Alon and Ruth licenses might be right on the border or possibly passing over into it but on the other hand there might be nothing right in the disputed area. The disputed area between what Israel and Lebanon claims is based on two different methods of setting the border. Israel contends that the maritime border between Israel and Lebanon passes along the equidistant line between the coasts of both countries, namely a line drawn up perpendicular to the coast, whilst Lebanon claims that the line must be drawn in continuation to the coastal border line with the difference being about 15 km in its widest point and in total is something like 1,100 sq km. The border dispute between Israel and Lebanon in fact exists since 1948 but the dispute has been renewed because of the gas discoveries in northern Israel in 2009.
MNI Minister Landau said that Israel had examined with international legal experts the issue of the border between Israel and Lebanon and that the border between Israel and Cyprus is what determines the line between Israel and Lebanon
