Solar energy, wind energy, geothermal energy, ocean energy, etc.
Compared with conventional energy, new energy is obtained by using new technologies and new materials, and is systematically developed and used on the basis of new technologies. Like solar energy, wind energy, ocean energy, geothermal energy, etc. Compared with conventional energy, the new energy production scale is smaller and the scope of use is narrower. The distinction between conventional energies and new energies is relative.
Regarding wind power generation and solar power generation, please ask experts to give me detailed answers.
The positive and negative poles can be directly connected to a small fan. If you charge a mobile phone, it is better to use an aba moduleDC-DC generator to reduce it to 5V, or directly. use a 7805 three-terminal voltage regulator block to step down, but the efficiency is lower.
If the battery has an overvoltage protection board, you can simply connect a diode in series at the output end, then connect it to the battery
The cost of solar power generation is high, and the current highest power generation efficiency is 21%, usually around 15%. This type of energy production is mainly used for low-consumption electronic components. The efficiency of wind power generation is about 40-50%, and the cost is relatively low. However, it is indeed easy to damage it, because the generator is exposed to wind and sun all year round. Additionally, as the wind comes and goes, the power output of the generator changes. Also, electricity must be used at night, beats themteries must therefore be charged during the day to provide energy at night or to store electrical energy. As the output power of the wind turbine changes, the battery will be damaged during charging. (Different battery types have different charging methods.) Also. If your electrical devices use AC power, a DC-AC circuit board is required to discharge the battery. However, these items are now available in matching packages and manufacturers can customize them according to your needs, but they are quite expensive. Nowadays, wind power is mainly used on small fishing boats. In fact, these current power generation methods such as tidal, solar, wind and geothermal power are not yet very mature and the prices are still relatively high, so I suggest you buy a transformer worth to severaltens of thousands of dollars to connect the lines. . Playing on mobile is tiring, and I don't ask for experience or wealth. I hope this will help you.
