On carbon emissions from fuel sources
In today's world, carbon emissions are related to all things, and the theory of their sources is quite important. Fuel sources of carbon emissions vary in type and each has its own feelings.

Firewood is a commonly used fuel in ancient times. In the past, people used firewood for cooking and heating. However, when it is burned, there are also carbon emissions. Although compared with today's energy sources, its carbon emissions may be slightly less, but it is widely used, and there is also a considerable amount.

Coal was once the main energy source for the rise of industry. Its reserves are abundant, powerful and affordable. Industry flourished, relying on coal as power. However, the burning of coal has a huge amount of carbon emissions. Black smoke rises, carbon is scattered in the air, causing qualitative changes in the atmosphere, and the greenhouse effect gradually becomes apparent.

Oil is also an important source. Vehicles travel on the road, boats are floating in the sea, and planes fly in the sky, relying on petroleum products. Gasoline, diesel, etc. are used for their power, but the carbon emissions they burn account for a large proportion of global carbon emissions.

Natural gas, compared with the previous two, is slightly cleaner. The carbon emissions it burns are relatively small. However, it is widely used, and the accumulation of less adds up to more, which is also the main reason for carbon emissions.

Looking at the carbon emissions of various fuel sources, when thinking about the way to change. Research new energy, such as solar energy, wind energy, water energy, etc., all have little or no carbon emissions. Gradually abandon the fuel source of high carbon emissions and switch to clean energy, which is a long-term solution, so that I can live in a world with clear sky and clear air, and all things are peaceful.
