Fossil fuels (non-renewable resources)

Fossil fuels were gradually formed by ancient organisms buried underground and undergoing complex changes under insufficient air, high temperature and high pressure for a long time.

1. The burning of fossil fuels

Fuels such as coal, gasoline, kerosene, diesel and liquefied petroleum gas

In addition to carbon and hydrogen elements, it also contains small amounts of sulfur and nitrogen elements.

Combustion produces sulfur dioxide and nitrogen oxides, polluting the air

Different fuels have different compositions, properties, and usage, storage and transportation methods.

Coal is cheap, easy to store and transport, but difficult to ignite and produces black smoke and dust when burned

Alcohol is easy to ignite and does not produce black smoke or dust when burned, but it is very expensive and difficult to store and transport.

[Thinking] What factors should be considered when choosing fuel?

2. Comprehensive utilization of fossil fuels

Coal - the "food" of industry

Coal reserves exceed 1 trillion tons, accounting for more than 90% of my country's total fossil energy reserves. Accounting for about 70% of my country's total energy consumption.

Fossil fuels and other non-renewable energy sources have limited reserves, and they easily produce polluting gases and smoke after use. Therefore, we must improve energy utilization and develop new green energy sources.
