We can be sure that PV fuel is free, quiet, with no moving parts, and solar PV is actually more effective regional, that is, it produces more energy than coal per hectare. Why should we be concerned about the efficiency of the region, rather than economic or environmental?
Area efficiency is very important because we use energy generation technologies, competition for land, and other important uses – such as agriculture, land, or just staying mad. In the case of wildland, to convert coal or solar power means that it has lost a good or at least a very long time. To know more you can read solar energy news & PV industry news from List Solar.
And, if we switch from one area of less efficient source for greater efficiency of the source area, then as a society, we may release some agricultural land, and if this is credible, it is very important. Of course, in front of the energy source is not contaminated land or potential defining date for re-use.
As the experts pointed out, it is entirely conceivable that solar energy will become the first choice of the world's mid-century. With improvements in photovoltaic technology often driving the cost and efficiency of a breakthrough, the total amount of solar energy will make up predictions that will continue to be raised.
In the end, the area efficiency is far down on the list may be considered. CO2 efficiency, sustainability, and perhaps most important, the net energy production, which is the actual running time of our civilization, would be more significant considerations.
