Lately I&amp;#x27;ve been reading Saul Griffith&amp;#x27;s book &amp;quot;Electrify&amp;quot; which proposes a different tack - &amp;quot;simply&amp;quot; electrify all energy usage and let people maintain their current lifestyles exactly. Interestingly, doing so would &lt;i&gt;reduce&lt;/i&gt; total US energy consumption[0] to about half its current levels while still allowing big trucks and air conditioning and fun energy-intensive things. A lot of that energy reduction comes from a) the higher intrinsic efficiencies of electrical machines and generation compared to heat engines and b) no longer needing energy to run fossil fuel exploration, extraction, and refining processes.&lt;p&gt;Griffith is also careful to note that climate solutions are &amp;quot;yes ands&amp;quot;, so we should increase efficiencies as much as we can in addition to electrifying as much as we can (and also pursuing ambitious strategies like fusion and CCS). Definitely make a great case of rolling out existing solutions like solar and wind in a big way to bring down carbon emissions really quickly.&lt;p&gt;[0] - the book focuses only on the US, but results could be similar in countries with similar economies.</text><parent_chain></parent_chain></comment><story><title>Climate change won’t wait for future innovation – we need action now</title><url>https://www.nature.com/articles/d41586-022-00560-2</url></story>

We should also do now the ones that are already available right now (like home insulation).&lt;p&gt;On the same line though decommissioning nuclear plants in Europe was always a bad move.
Italy abandoned nuclear with a referendum 1987 just after Chernobyll and again voted against nuclear in 2011.
Italy then buys nuclear energy from France and gas from Russia. This is just putting the head in sand and moving the problems out of sight.
Germany is&amp;#x2F;was about to make the same mistake.
Nuclear is a far from perfect solution available now which is beeing replaced for the hope of a much better solution much later on. We are not sure we&amp;#x27;ll get the much better solutions down the line. We should make all the green(ish) bets we can.</text><parent_chain></parent_chain></comment><story><title>Climate change won’t wait for future innovation – we need action now</title><url>https://www.nature.com/articles/d41586-022-00560-2</url></story>
