&gt; $.10 to .15&#x2F;kwh is realistically the range battery technology will be in for the next 10-15 years<p>Forgive the lack of citation, but Goldman Sachs just put out a report on Tesla within the last few days, and they&#x27;re estimating the cost of batteries dropping ~60% over 5 years due to the Gigafactory producing 35GW of storage each year.<p>EDIT: Found it, <a href="http:&#x2F;&#x2F;evannex.com&#x2F;blogs&#x2F;news&#x2F;75718469-goldman-sachs-bullish-on-electric-vehicles-tesla-gigafactory-leading-the-charge" rel="nofollow">http:&#x2F;&#x2F;evannex.com&#x2F;blogs&#x2F;news&#x2F;75718469-goldman-sachs-bullish...</a><p>&quot;Discussing electric vehicle batteries, Goldman reports that: &quot;technological advances play a significant role, growing economies of scale are the key driver of cost reductions. Led by Tesla and Panasonic’s 35GW Gigafactory, battery manufacturers have committed to approximately triple current production capacity over the next five years [Exhibit 36].... Autos analysts forecast the battery range for lower performance EVs to increase by over 70%, while battery costs are expected to fall by more than 60% over the next five years [Exhibit 37].&quot;&quot;
