Presently, the World is heavily dependent on Oil as the only major source of Energy. Based on current rate of World's Energy consumption, Energy experts predicted that the Estimated Total World's Oil known Reserve would last for about 30-60 years. Before the wells of the Oil producing nations runs dry, every nation will be feverishly stockpiling the precious oil at a very early stage i.e. 10-20 years before depletion. With a drastic increase in the price of Oil, electrical lighting will become prohibitive.
Currently, all buildings are design with the concept and/or basis of a total dependence on a steady supply of Electricity at current stable Utility prices.
Obviously, these buildings are built to withstand beyond the Oil Depletion Dateline. The concept of using electrical lighting as the only form of lighting place building owners at the mercy of the Utility Company for the entire life span of the said building.
It is the standard practice of the Power companies to pass on any Fuel Oil increases to the consumer and will be reflected in their Monthly Utility Bills.
Correcting these design flaws takes a long time as there are numerous other considerations as all these buildings maybe occupied and/or in operations.
From decision-making to feasibility study to concept design and the scale of Sunlight Lighting Retrofitting may require 5-10 years or more before a viable alternative energy usage program could be implemented and/or installed.
Therefore, the World must take immediate steps in considering the use of an alternative and secondary energy source in all future buildings and homes.
