Problems solved by technology
Therefore, the use of solar power to generate electricity has the problems of high cost and low conversion efficiency.
The use of geothermal power generation requires the use of other fuels as auxiliary heat sources, such as combined power generation with gas. The system structure is complex, maintenance is difficult, and the cost of power generation is high.
It can be seen that most of the existing energy solutions only consider the development and utilization of new energy sources to reduce environmental pollution, but do not consider the solutions to the environmental pollution problems that have been caused.
Or consider only solutions to environmental pollution without mentioning energy issues
The resulting redundant construction and high investment have become environmental burdens and energy waste in disguise
