Stanford University research found that global energy consumption decreased by 23% when switching to green electricity. Stanford University's "School of Earth, Energy and Environment" published a study that investigated 139 countries that contributed to global carbon emissions by 99%. According to the renewable energy resources of each country, Anticipate future transformation scenarios. This study took many factors into consideration, including electricity, transportation, air conditioning, industry, agriculture, forestry, fishery, and animal husbandry. For countries with vast territories, they have the most space to develop renewable energy and are easiest to transition to relying on renewable energy for power supply, because solar and wind power generation have higher production capacity due to the larger the area. As for a small country like Singapore, it has to go to the ocean to develop offshore wind power. After completely switching to renewable energy, by stopping the development of oil and natural gas, the costs of extraction, transportation and refining can be saved, and the world's energy expenditure will be reduced by 13%. Without oil, internal combustion engines using gasoline will no longer be used. Since electric motors are more energy efficient, replacing the former will reduce the world's energy demand by 23%. While oil industry jobs will disappear after a complete transformation, the jobs created by renewable energy will far outweigh the jobs lost. According to statistics from this study, 27.7 million jobs disappeared, but 52 million jobs were created, an increase of 24.3 million.
