In today's world, the main reason for studying carbon emissions is the source of energy. Various types of energy have different effects on carbon emissions.

Firewood is commonly used in ancient times. Although it generates heat for heating, it also releases carbon when burned. Its quality is miscellaneous and cannot be burned. Carbon escapes in the air, resulting in the accumulation of carbon emissions.

Coal is a huge energy source. Industry is prosperous, and it is widely used. When a large furnace is burned, the power is generated, but the carbon emissions are huge. Thick smoke covers the sun, carbon accumulates in the air, and the greenhouse effect gradually becomes apparent.

Oil is the power of the car. The fuel engine roars, and the carbide comes out with the exhaust gas. The road is vertical and horizontal, and the carbon is scattered in all directions, which is another source of carbon emissions.

Natural gas is cleaner than the first two, and it generates carbon when burned. Although the amount is slightly small, there are many users, and the sum adds up to more, which also increases carbon emissions.

As for water energy, wind energy, solar energy, and clean energy. Operation does not have the worry of carbon emissions, and can replace various carbon sources, which is the way to reduce carbon emissions. Therefore, we should vigorously promote this kind of problem, reduce carbon emissions, protect the world's peace, and protect the well-being of all generations.
