The thermal power station is coal fuel.Because the world coal many of the storage capacity,coal prices are lower.And construction of a hydropower station over the same cost of hydroelectric power stations to low-cost,because thermal power stations only need to build furnaces,exhaust facilities,generators,coal facilities,construction of these components are quite safe.and the construction of hydroelectric power stations,even before the construction of a dam with numerous steel cement in the river reservoir built,Drivers can use hydraulic generator.Thermal energy from the impact of climate,hydroelectric affected by climate.However,after the burning of coal of non-renewable and energy efficiency is very low,only less than one third of energy use,two-thirds of the heat energy,will be,so that the water near the river rose several degrees,the fish died.But emissions from power stations is also pollute the environment.
英语翻译这一段:火力发电站用的是煤燃料.因为地球上煤的储存量很多,所以煤的价格较便宜.而且建一座火力发电站的成本比同样功
