New energy technology is an important direction in the future energy field. Driven by the "dual carbon" goals and technological progress, the widespread application of new energy will bring about energy structure adjustments, which will greatly change China's socio-economic production and lifestyle, including the following aspects:

1、 Application field:
1. Solar energy: Solar energy is currently the most widely used new energy source, mainly used in photovoltaic power generation systems. Photovoltaic power generation refers to the conversion of solar energy into electricity, including rooftop photovoltaics, solar power stations, etc. Another way is solar thermal energy, which refers to the use of solar energy to generate heat for heating or heating water.

2. Wind energy: Wind energy refers to the energy generated by converting wind energy into electrical or mechanical energy. Wind energy is mainly used in wind power generation systems, including onshore wind power and offshore wind power. Wind energy is a clean energy source that does not emit pollutants.

3. Hydroelectric power: mainly used in hydroelectric power generation systems, including dam power generation, tidal power generation, etc. Water energy is an efficient energy source that does not emit harmful gases and has a lower risk of environmental pollution and ecological damage.

4.Biomass energy: Biomass energy refers to the process of converting biomass into usable energy. Mainly used for biomass power generation, biomass 4 production, material thermal energy utilization, etc. Biomass energy has advantages such as renewable, non-toxic, and low pollution, which can reduce dependence on traditional energy and therefore has high development prospects.

5.Geothermal energy: Geothermal energy is natural thermal energy extracted from the Earth's crust, mainly used for geothermal power generation and ground source heat pump systems. It has advantages such as large reserves, wide distribution, green and low-carbon, strong applicability, and good stability. 2、 Development trend:
1. Energy storage technology: The development of various types of energy storage technologies for new energy can store the remaining electricity generated from new energy generation, reduce energy waste, and also use the peak valley difference in electricity prices to reduce the cost expenses of enterprises, which can improve the sustainable utilization and stability of new energy.

2. Multi energy complementarity: Different new energy technologies can be combined to form a multi energy complementary system, such as solar energy+wind energy, solar energy+energy storage, which can effectively improve energy utilization efficiency.

3. Intelligent integration: Combining new energy technology with intelligent control technology to achieve intelligent monitoring and management of energy systems. For example, current energy storage power stations can achieve remote monitoring and unmanned management mode. Through remote monitoring data, the operation of the power station can be managed in a timely and effective manner.

4. Urban energy transformation: New energy technologies can promote the transformation of urban energy systems, achieving clean, low-carbon, and intelligent urban energy supply.

5. New material application: The application of new materials is also one of the trends in the development of new energy technology in the future. By developing new materials, the efficiency and stability of new energy equipment can be improved.

Various new energy technologies also have different characteristics and functions. The characteristics of solar energy are renewable, pollution-free, and widely distributed.
