1. That amount...Here are some pertinent questions:<br /><br />1. That amount of land is supposed to cover all our energy needs or only the electric ones?<br />PKn: Don't know, no reference given.<br />2. Does that amount of land include the space needed for the pairing fossil fuel power plants (to supply power at night or during cloudy days)?<br />PKn: I don't expect this. On the other hand this is minimal. As fossil fuels plants are having a small surface area (and you could even combine this by covering the fossil plant with PV-panels ;-))<br />3. If no pairing fossil fuel plants are being considered, then, does that area include the massive storage capability that would be needed (banks of industrial batteries, lakes, etc.).<br />PKn: This is much much smaller then land requirements for harvesting the energy.<br />PKn: 2nd: You can install the batteries below the panels.<br />4. Is the area needed by the inverters and transmission lines already included?<br />PKn: This is neglect-able and can be combined with the PV-panels.<br />5. And probably the most important of all: do those areas include the massive mining / manufacturing / assembly operations required for such a solar PV build-up and for the regular replacement of all the components in this global system?<br />PKn: I don't think so, but can't check (no links, references). But this is much smaller then the land requirements/<br />6. Let's not forget that also massive amounts of transportation / construction equipment would be required for that build-up: ships, trucks, cranes, forklifts, etc., etc., and all this equipment needs space to be build (and mining operations to obtain the raw materials). <br />PKn: Indeed. But this is "once only" .<br />But the whole idea is to show in a picture the scale. <br /><br />Some renewable promoters bend backward in such awkward and painful positions to try to justify the unjustifiable that the word that comes to my mind is: dishonesty.<br />PKn: Or reverse you can bend forward and start.<br /><br />Maybe I'm wrong and they are just overeager.<br />PKn: My comment Pol KnopsPol Knopshttps://www.blogger.com/profile/05225274116507492775noreply@blogger.comtag:blogger.com,1999:blog-5942955863194137754.post-16925685721658294172015-04-27T15:09:32.386-05:002015-04-27T15:09:32.386-05:00I don't think it's really out-and-out dish...I don't think it's really out-and-out dishonesty.<br /><br />They are so in love with the concept of solar PV that they just get carried away. A passion can forgive so many sins! <br /><br />The trouble is that this passion ignores any unpleasant truths that get in the way of the adoration. <br /><br />This is true love.<br /><br />There is no place for hard nosed science and engineering.BilloTheWisphttps://www.blogger.com/profile/16221663524948086557noreply@blogger.com
