In today's world, the pursuit of energy is to clean and carbon-free people. Capping carbon emissions will cause climate change, which is very harmful. It is to investigate the source of carbon-free energy and seek long-term solutions.

The so-called source of carbon-free energy is the first to push sunlight. Sunlight shines on the earth, endless. With the technology of photovoltaics, light energy can be converted into electricity, installed on rooftops and wilderness, convenient to use, and pollution-free to the environment.

Secondly, wind power is also the best choice for carbon-free energy. Wind moves in the wild, and its power can be used. Build windmills on the beach and on the top of mountains, and run with the wind to generate electricity for civilian and industrial use. Where the wind comes, electricity follows, and it does not generate carbon emissions, which is beneficial to nature.

Furthermore, hydropower is also a carbon-free energy source. Rivers flow day and night. Dams are used to intercept the flow, so that the energy of water can be converted into electricity. This energy is stable and efficient, and has a great impact on people's livelihood.

The energy of geothermal energy cannot be ignored. The inherent heat in the ground, derived from technology, can be used for heating and power generation. Its source is deep underground, inexhaustible, and there is no risk of carbon.

As for biomass energy, it can be converted into carbon-free energy through scientific methods. Such as grass, straw, etc., processing and transformation can also generate electricity and heat, and help to deal with waste.

Today, this kind of carbon-free energy source should be widely promoted, so that the people know the benefits, and the government will help to promote it. Develop advanced technologies, reduce their costs, and increase their efficiency. In this way, the energy will be clean, the environment will be beautiful, and future generations will also enjoy its benefits.
