USA HISTORY

Detailed explanation-1: -In the second half of the 20th century, we see the emergence of yet another source of untapped, at the time, energy. Nuclear energy! The third revolution brought forth the rise of electronics, telecommunications and, of course, computers.

Detailed explanation-2: -People found an extra source of energy with an incredible capacity for work. That source was fossil fuels-coal, oil, and natural gas, though coal led the way-formed underground from the remains of plants and animals from much earlier geologic times.

Detailed explanation-3: -Nuclear Power Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.

Detailed explanation-4: -In the IR3, great inventions were semiconductors, mainframe computer, microprocessors, MOS transistors, worldwide web, internet (an ultra-fast 5G communication internet, a renewable energy internet, and a driverless mobility internet), renewable electricity, e-commerce around 1995, and later developed Smartphone [41].
