From 1850 to 2019, humans have emitted a total of approximately 2.4 trillion tons of greenhouse gases. The impact of climate change on the environment, society, and economy is increasingly intensifying. The frequency of extreme weather has increased, sea levels have accelerated, and millions of species are on the verge of extinction. In order to deal with climate change, nearly two hundred countries around the world adopted the Paris Agreement in 2015, explicitly reducing greenhouse gas emissions, controlling temperature rise within 2°C of pre-industrial levels within this century, and striving for a climate consensus of 1.5°C. The world needs to Achieve net-zero greenhouse gas emissions around mid-century.
Some experts say that in order for the world to gradually achieve the goals set by the Paris Agreement, the speed of expanding the scale of renewable energy needs to increase by at least six times.
More than half of the world's greenhouse gas emissions come from the energy industry. Therefore, the energy industry is the area of emission reduction that countries attach most importance to, and faces arduous emission reduction tasks.
As an electronic device that can convert energy, distribute electricity and power electronic devices, inverters can play a driving role in achieving the goal of energy transformation. In a solar photovoltaic system, the electricity generated by the solar panels is direct current. Inverters convert this DC power into AC power for use in homes, industrial and commercial applications, or to inject excess power into the grid. Wind turbines (wind generators) often produce alternating current, but their output may not match grid requirements. The inverter can adjust the frequency, voltage and waveform of the output power to adapt to the grid. In an electric vehicle charging system, an inverter is used to convert alternating current from the grid into direct current suitable for the electric vehicle battery. The inverter can also release electrical energy from the electric vehicle battery to the grid when needed, enabling two-way energy flow between the grid and the electric vehicle.
As battery technology advances, energy storage will also become an important part of the power system. Energy storage can help balance the volatility of renewable energy and improve the reliability of power systems.
Portable power supplies can store and utilize renewable energy through solar panels. This product is easy to carry and has complete functions. It is a good helper for traveling and camping, and it is also a practitioner of clean energy.
As the energy transition progresses, we are also aware of the importance of carbon neutrality. The greenhouse effect, melting glaciers, and severe weather are signals sent by nature. Nature is reminding us to reduce carbon emissions and develop more renewable energy. Of course, achieving this goal also requires each of us to save and reduce emissions, and the world will achieve zero-carbon development.
