H. How energy is playing a major bottleneck in technological advancement and scale?
Theoretically, based on the first principle of thermodynamics, energy utilization has to be kept constant, or else the food, water, and land will decrease.
In 1179 BCE when the Bronze Age finally collapsed, there were earthquakes, draughts, pandemics, no water, and limited food, because everyone wanted Bronze tools, and everyone developed metallurgical technologies.
UAE was created in 1920 based on a new energy source, that is Oil. Modern America got created due to Oil. Modern England got created due to coal. All the wars have been fought to secure more energy at that time and have access to more fertile lands.
In the Industrial Age, new machines were constantly invented to improve the combustion engine efficiency, and using the same in different areas of life. Then they became junk after the Petrol age.
Solar inventions, understandable, good or bad, adhere to energy. With mobile and laptops, no youth is seen making more barren lands fertile(in fact opposite, offices are created after making lands NA).
