Peak OilThe world relies so heavily on oil that the question arises: How much oil is left? A simple answer to this question would be overkill, however the speed and cost of production is an entirely different matter. Oil must be extracted and refined at a rate that keeps pace with consumption to avoid a supply disruption. The most commonly used oil so far has been conventional oil, that is, oil in a liquid state extracted from underground or from the sea, and it covers the lion's share of our demand. As global demand for oil increases, it becomes important to try to assess the ability of the world's oil fields to meet our demand. When we study the production of an oil field to try to derive when an oil field has reached its maximum rate of production before the rate of production begins to decline, we call this point its peak production or Hubbert Peak, named after the infamous geologist M King Hubbert. Hubbert Peak works like this (as oil is extracted from a well, production will increase until it reaches a point of maximum production where it peaks or plateaus and never exceeds that production rate again and then will gradually always produce less until it runs out) ). This describes the natural extraction and production of an oil field but, as King Hubbert himself explained, advanced techniques could keep production high or stable long after the oil field has passed its natural peak. Such an oil field might behave very differently in its depletion, where production might suddenly decline sharply because examining the production rate might not accurately represent the state of that field. While most of the oil we have produced is so f... half paper... consider that because eventually and inevitably we will run out of oil and you will still want to be able to function and where you live will determine that. The original suburbs were designed with mass transit in mind, sometimes referred to as streetcar suburbs, built from the early 1900s until just before World War II, but many of these neighborhoods have deteriorated since then. So a combination of restoring these neighborhoods and converting neighborhoods that can be converted to rail should be a priority; Furthermore, we will have to reallocate farmland that has been transformed into suburban neighborhoods into agricultural land to maintain our ability to produce enough food. The good thing is that as closer living conditions develop, the railway will be able to serve us better, this is easy to see in cities and towns across Europe.
