For example, TX is anticipated to add 10 GW of new solar generation in 2022.[1]  As I write this (while the sun is up, noon in TX), the current demand in TX is 38 GW.[2]&lt;p&gt;Source: Have been developing solar power plants since 2008.&lt;p&gt;[0] The tipping point for solar is different in different regions based on many factors, but primarily the amount of annual sunlight and the cost of fuel on the margin, and regulatory policy.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.reuters.com&amp;#x2F;business&amp;#x2F;environment&amp;#x2F;texas-track-add-record-solar-power-capacity-by-end-2022-2021-04-21&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.reuters.com&amp;#x2F;business&amp;#x2F;environment&amp;#x2F;texas-track-add...&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.ercot.com&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.ercot.com&amp;#x2F;&lt;/a&gt;</text><parent_chain><item><author>credit_guy</author><text>&amp;gt;  Utility scale solar PV [...] is now the cheapest form of new energy to deploy.&lt;p&gt;I&amp;#x27;ve been hearing this claim for a few years now, and I took it at face value, until a few days ago.
