See: [[To replace or not to replace]].<br /> <br /> <br /> ====&quot;Is there any point in saving ''electricity'' in the winter if I have to use electric space heaters anyway?&quot;====<br /> No. [[Wasted electricity is the same as electric heating]].<br /> <br /> Saving energy in the winter is all about [[save energy on heating|saving energy on heating]].<br /> <br /> <br /> &lt;!--<br /> ====&quot;Is there any point in saving ''electricity'' if my local town/city is powered with all renewables anyway?&quot;====<br /> Yes. Renewable energy sources still have a ''maximum output power capacity''. Anytime that capacity is exceeded, [[fossil fuel]] power plants are used to fill in the gap. On the flip side, whenever demand is ''below'' capacity, the [[surplus electricity]] could (in principle) be put to good use, such as for producing [[hydrogen gas]] that could later be burned in place of fossil fuels. In any case, we're going to need all the electricity we can get, so we shouldn't waste it. Also note that [[nuclear power]] is not unlimited either, because uranium is a finite resource.<br /> --&gt;<br /> <br /> <br /> ==See also==<br /> * [[Climate change]]<br /> * [[Reduce the amount of land needed for agriculture]]</div>
