Hydro power plants it seems, generate more electricity than a coal power plant. Water is supposed to be environmentally friendly, but the opposite view is, the land, around the river, is very submerged. Now, a general idea, about Hydroelectricity, is build a reservoir on the side of the river, which is appropriate, and let the river flow. It appears, the reservoir will fill up, and electricity needs to be generated, only. This has nothing to do with the game. In the game, the only way to go is to be aware, that we can consume, and produce more, but we are not doing that, as a nation. I have 9 research slots. I do spend on production. The issue with me is, that I have pretty advanced tech., but I have asked my production minister to conserve as a policy, and to let supply be limited to demand, not to grow in a significant manner. The conserve request, must mean that the ecology and environment is conserved, production being the important function of an economy, and nation. I think, canals can be built if rivers are not dammed, and this must be the way out. If people consume less electricity, not because they need more, but because they feel secure about the electricity supply, then it will be good.
