<p>[QUOTE=&quot;desertgem, post: 1587123, member: 15199&quot;]The current photovoltaic uses about 20 grams per 200 watt generated. This is &quot;printed&quot; on the solar cell itself, but has been replaced in some solar cells by a &quot;thin film &quot; process similar to computer chips, which can use substances other than silver. These are for the most part panels to be evaluated, as the silver printing process is faster and less expensive if we leave out the silver price, compared to the &quot;thin film&quot; process, but even there they are reducing the actual silver content as methods improve. My non-blog opinion is that silver will eventually be used in a % lesser than 25-50% of current use by then, IF solar panels survive. The demand seem to have fallen of the roof ( pun intended). All In My Opinion. Invest in personal geothermal energy generation companies, they are the next Hot thing <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
