There are several answers to this.  The three that stand out to me are alternate power generation methods (inferior, but still helpful), designing systems with excess battery capacity, and, you know, using less energy at times when it&#x27;s harder to generate.<p>People tend to be dismissive about conserving energy, but I expect they would think differently if they were producing &amp; storing their own.  We use way more than we need to-- some of the biggest power hogs are air conditioning and refrigeration, neither of which is necessary in the winter.
