Personal opinion: equally powerful
In terms of itself: water is powerful, source of all things, infinite. It has strong reproduction and recycling capabilities.
The power of fire lies in its release. The ability to spread, using wind to create momentum, everything is afraid of fire, because everything is flammable. There are people who are not afraid of water, but there is no one who is not afraid of fire.
Judging from the current situation, the thermal energy industry is doing better.
Because thermal power plants burn coal to produce electricity, the current price of coal has fallen, and the cost of thermal power plants has also fallen rapidly. However, the price of electricity has not changed, nor the profits. the electricity production margin is enormous.
In the cement industry, as state investment in infrastructure has been significantly reduced, thedemand for cement is lower, the price of cement is lower and the profit margin is low.
