It's always sunny in low earth orbit, so what better place to look for solar energy? With the rapid approach of "cheap oil" drying up and the impact of fossil fuel use on the environment and climate, clean renewable energy seems inevitable to become the future trend. The key factor in all these business ventures is efficiency, which is how best to manage, create and distribute energy. Oil and coal must go through the process of extraction, shipping, refining, and combustion, and add greenhouse gases to the atmosphere.
Wind needs two conditions to convert to wind energy. One must have a wind turbine. Water requires the construction of a dam, which is not only expensive but also quickly changes the river's ecosystem. Even solar panels on the ground will be affected by the weather and Earth’s day and night shifts.
The concept of space-based solar energy is to use orbiting solar panels to continuously collect unfiltered energy from the sun, and send these energy back to Earth so that communities can use the solar energy transmitted through the network. The sun continuously emits extremely large amounts of radiant energy in all directions. (Energy generated per second is roughly equivalent to the annual power generation of 2 billion power plants.) This energy output only receives a small fraction of the Earth's energy, and capturing the sun's radiant energy may provide renewable, almost pollution-free energy. Especially those where regular grid access is limited or difficult. Large solar cells will collect solar energy and transmit it wirelessly to substations on the ground. Substations will then distribute these currents.
Mark Hopkins, senior vice president of the National Institute of Astronautics, claimed: "Since the United States now decides to respond to the energy challenges of the next 50 years, space solar energy must be part of it. The National Security Space Office responsible for this research has developed The direction: While the technical challenges are real, major investments are currently being made to make space solar energy the ultimate source of energy: clean, green, renewable, and able to provide us with a lot of energy. Congress, federal agencies and the business community should begin immediately. Make investment."
We will wait and see for the long-term development of the concept of space solar energy in the next four years. At the same time, countries around the world will continue to discuss how to better cope with the complications caused by climate change. Although space solar is still far from successful, it still requires a lot of research and engineering to make it a reality in the near future. Given the launch vehicle and rail supply management, space solar energy is technically feasible. However, the development and testing of this technology should not be delayed as soon as possible, so as to ease the pressure on us to rectify the energy law.
Whether we are fully prepared or not, the future is gradually coming. We need to be prepared to cope with the energy needs of population growth, and even if space solar energy cannot replace traditional energy in the near future, it may be able to provide a supplemental energy that has little negative impact on the environment.
