What is energy storage?What is energy storage?Energy storage refers to the technology of storing energy in some form and releasing it for use when needed. Its core function is to solve the mismatch problem of energy supply and demand in terms of time or space, improve energy utilization efficiency, and ensure the stable operation of the power system. 1. Why is energy storage needed? Balance supply and demand: Renewable energy sources (such as wind and solar) are intermittent (dependent on weather), and energy storage can "peak shaving and valley filling," storing electricity when generation is high and discharging when generation is low. Improve grid stability: Reduce power fluctuations, avoid power outages or voltage instability. Lower electricity costs: Charge during off-peak hours at lower rates and discharge during peak hours to save on electricity bills. Support electric vehicles and off-grid applications: Such as home energy storage, mobile device power supply, etc. 2. What are the main classifications of energy storage technologies? Energy storage technologies can be classified by storage form.

What is new energy?What is new energy?New energy refers to clean, renewable, or low-carbon energy forms other than traditional fossil fuels (such as coal, oil, and natural gas). Its core characteristics are environmental protection, sustainability, and its contribution to reducing greenhouse gas emissions. 1. Solar Energy Converts sunlight into electrical or thermal energy through photovoltaic power generation (solar panels) or solar thermal technology. Characteristics: Unlimited resources, widely distributed, but affected by weather and day-night cycles. 2. Wind Energy Utilizes wind turbines to convert wind energy into electrical energy. Characteristics: Clean, costs decreasing year by year, but requires stable wind resources. 3. Hydropower (small hydropower/tidal energy/wave energy) Includes not only traditional large dams but also the utilization of tidal, wave, and other marine energies. Characteristics: Renewable, but impacts on the ecological environment.
