What is feasible?

Based on our Red stack, Green stack analysis, Kuwait should be able to produce more energy than it consumes. However, according to McKay, Kuwait consumes about 330 kWh/d/p, which is a difference of 203 kWh/d/p. This could be because most of our numbers were estimated by using ratios from different countries, due to lack of information found on Kuwait.  Also, in our red stack analysis, numbers calculated were fairly lenient (average numbers), meaning some numbers could have actually been more than calculated. Imports were also not included in the production of energy. In the green stack analysis, economic, social, and environmental constraints were considered for the wind. And some of our "green" energy would not be compatible. For instance, Kuwait would most likely not use both deep and shallow offshore wind, mainly based on aesthetic reasons. Energy production numbers were very generous; for example, the PV farms energy (based on solar) was calculated to be 3497 kWh/d/p because Kuwait is assumed to be mostly all desert with a lot of sun.

Now we have to consider if it is even feasible for Kuwait to implement these energy production systems. Cost is probably the most important factor for Kuwait where they have a GDP of $131.3 billion, and a revenues/expenditures budge of $72.94 billion and $43.13 billion, respectively [1]. Obviously, Kuwait could not afford to put solar heating and PV farms over all their desert,  but surely some is feasible (perhaps a quarter making it 875 kWh/d/p).

Wind may not be too feasible because wouldn't want them ruining their backyards. Offshore wind might also not provide enough power for the amount needed to make much of a profit of it.  Tide power  and geothermal could be feasible based on our calculations .If we perform a similar ratio from the UK to Kuwait using McKay's numbers, our numbers decrease tremendously.

Thus our green stack boils down to as shown below:



Figure 1: Feasible production

The total production reduces to about 358 kWh/d/p, a huge decrease. However, this appears to still have a slightly higher production value compared to the energy consumption of Kuwait. Again, there was limited information to project the amount of energy consumption and the production is Kuwait's potential (Kuwait has not actually implemented all of these energy production systems).

If we really want to help, Kuwait cannot survive of just renewables alone. Some fossils fuels have to be used or something like Nuclear seriously needs to be considered.
