It's not as simple as hand-waving statements about electric vehicles adding to baseload demand - timing of use is key. Since EVs will tend to be charged overnight when demand is low, there is actually a huge synergy between EV uptake and expansion in wind power and other intermittent renewables.<br /><br />You should check out this report from the Centre for Advanced Engineering for some actual modelling and numbers.<br /><br />http://www.caenz.com/index.php?option=com_content&view=article&id=109%3Aelectric-vehicles-impacts-on-new-zealands-electricity-system&catid=8&Itemid=64<br /><br /><br />They find:<br /><br />• Additional non-schedulable generation is made economic by the use of off-peak and shoulder hour battery charging. This results in a significant amount of additional wind capacity being added to the system, with smaller amounts of hydro, marine and biomass.<br /><br />• By displacing some fossil fuelled peaking plant due to additional non-schedulable renewables becoming economic, total CO2 emissions from the power system are reduced, despite the increased load. <br /><br />• By 2025, over 390,000 electric vehicles are in use under this scenario, but total additional generation capacity has not exceeded 180 MW.<br /><br />• Assuming 15% of charging occurs randomly, including over the super peak hours, has no significant effect on the average cost of generation, but might have some effects in transmission and distribution systems.Paul Youngnoreply@blogger.comtag:blogger.com,1999:blog-2830084253401570472.post-8680698237046981022012-11-15T14:17:35.169+13:002012-11-15T14:17:35.169+13:00Read David Friedman on cold houses in warm climate...Read David Friedman on cold houses in warm climates; that drives a lot of it. Were we replacing windows at our place, we'd totally be putting them in.<br /><br />When I first got here, I thought that it was moral failing on the part of Kiwis. Kiwis simply think it good for their souls to have to wear itchy woollen sweaters indoors. And having a wooden tent for a house is a good way of making you wear your cilice. I'm rather far to the left on the hedonist / mortificationist axis. <br /><br /><br />Newer places are putting them in though, and I'm seeing more builders advertise that their houses come with double-glazing. So things are getting better. <br /><br /><br />A lot is legacy of the stock of housing built when electricity was heavily subsidised.Eric Cramptonhttp://offsettingbehaviour.blogspot.com/noreply@blogger.comtag:blogger.com,1999:blog-2830084253401570472.post-30829720922778376292012-11-15T13:13:28.168+13:002012-11-15T13:13:28.168+13:00On the subject of energy efficient buildings, any ...On the subject of energy efficient buildings, any thoughts on NZ's antipathy to double-glazing?
