Fossil fuels such as coal, oil, and natural gas provide approximately 95 percent of the world's total energy. These non-renewable resources are the primary sources of energy for electricity generation, transportation, and heating in many countries.
As of 2019, natural gas accounted for approximately 32% of the total energy consumed in the United States.
Electric power energy provides about half of the total energy of the United States.
Nuclear power provides about 10% of the world's electricity. In countries like France and the United States, nuclear power plays a significant role in the energy mix and provides a substantial portion of their electricity needs.

Petroleum provides about 35% of the world's total energy consumption.
In the US, 19 percent of total electricity. In the world, about 16 percent
No. Less thsan one percent of the Sun's total energy falls anywhere near Earth.
Nuclear power plants provided 13.5 percent of the world's electricity production in 2010. In total, 15 countries relied on nuclear energy to supply at least one-quarter of their total electricity.
Only about 10% of the energy is transferred between trophic levels, so if 100% is available at the lowest trophic level, then only about 10% of the original energy is available at the highest trophic level.
