Energy is suitable for long-term holding. In the context of vigorously promoting carbon neutrality, the domestic power sector may become the largest innovation sector, and wind power and photovoltaic will inevitably usher in rapid development. Electrification is the core of carbon neutrality, and wind power and photovoltaic are highly expected in renewable energy power generation; At present, electric energy is the path with the lowest cost and the most mature technology to achieve carbon neutrality. The popularization of electric vehicles, artificial intelligence and building intelligence has improved the electrification level of end energy users, and traditional electricity has replaced the use of fossil energy such as coal and oil. China's share in power generation and heating industry and industrial production is obviously higher than the global level, and the power generation and manufacturing industry with the highest total carbon emissions in the process of carbon neutralization is expected to usher in the greatest innovation.
