some countries use low grade fuel because of pollution and they try to make their country a beautiful none pollutional place...
Fossil fuels are a source of chemical energy. Chemically conbining the hydrocarbons in fossil fuels with air is combustion and primarily produces carbon dioxide and water. (There are many more details of the chemistry of the specific fossil fuels and many other results of their combustion besides the predominant gasses of water and carbon dioxide.)
Fossil fuels, such as coal, oil, and natural gas, currently account for the largest share of the world's energy production. They are used for electricity generation, transportation, and heating in many countries.
Biomass is still a major source of energy in many developing countries, particularly in rural areas where access to modern energy sources is limited. In countries like India, China, and parts of Africa, biomass is used for cooking, heating, and other energy needs. Additionally, some developed countries, such as Sweden and Finland, utilize biomass for electricity generation and district heating.
It is estimated that about 20% of the world's total energy consumption comes from renewable sources such as solar, wind, and hydropower. However, the majority of global energy still comes from non-renewable sources like fossil fuels.
As of 2021, approximately 5.5% of global electricity is generated by wind power. The capacity of wind power installations continues to increase, with many countries investing in this renewable energy source to reduce reliance on fossil fuels.
Many countries use low-grade fuels due to their lower cost and availability. Additionally, the infrastructure to support higher-grade fuels may not be in place, and some regions may not have access to cleaner alternatives. Economic factors and the lack of strict regulations also contribute to the continued use of low-grade fuels in some countries.
There are many types of low-grade fuels. Some, for example, are wood, oil, coal, and other fossil fuels as well... fossil fuels are made up of the remains of dead plants and animals which have been placed under the pressure of the earths surface for thousands of years.
In richer countries it is usually electricity or fossil fuels. In poorer countries it is usually wood.
Many countries around the world use fossil fuels as a primary source of energy, including the United States, China, India, Russia, and Saudi Arabia. These countries rely on fossil fuels such as coal, oil, and natural gas for electricity generation, transportation, and industrial processes.
There are many sources of energy that can be converted to electric energy. In many countries, most electric energy is produced by fossil fuels -- mostly coal, some natural gas, etc. However, in a few countries such as France and Belgium, most electric energy is produced from something other than fossil fuels. What can you use instead of fossil fuels?
Many countries mined/produced gold. And many countries still do.
Many underdeveloped Arabian countries, 20+ of them.
That depends on the context. As a letter grade in schools in the United States and many other countries, a C is a passing grade, but only barely.
