Heating a house from 30F to 70F uses far more energy than cooling a house from 100F to 70F:

If it&#x27;s mostly coal-powered electricity, that&#x27;s pretty bad, considering the low efficiency and high CO2 output of coal burning electricity generation.  Obviously that needs to change.<p>Hopefully they start using more nuclear and renewables as the cost of those drops.  For one thing, India has incredible solar resources (<a href="http:&#x2F;&#x2F;mnre.gov.in&#x2F;sec&#x2F;DNI_Annual.jpg" rel="nofollow">http:&#x2F;&#x2F;mnre.gov.in&#x2F;sec&#x2F;DNI_Annual.jpg</a>,  <a href="http:&#x2F;&#x2F;www.dlr.de&#x2F;tt&#x2F;Portaldata&#x2F;41&#x2F;Resources&#x2F;dokumente&#x2F;institut&#x2F;system&#x2F;projects&#x2F;reaccess&#x2F;ssedni60.jpg" rel="nofollow">http:&#x2F;&#x2F;www.dlr.de&#x2F;tt&#x2F;Portaldata&#x2F;41&#x2F;Resources&#x2F;dokumente&#x2F;insti...</a>), being as close to the equator as it is, and it also has large populations living in areas with high irradiation, in comparison to Europe or even China.<p>Once the price of solar drops further (it&#x27;s within reach of the middle-class in US and Western-Europe), they will have even more reason to adopt it.
