Down here in Oregon coal, natural gas, and nuclear provide a larger share of electricity than "river water". Also with "deregulation" energy can come from far and wide and it isn't always going to come from regional sources. Especially in years with low snow pack. <br /><br />Oregon's largest energy supplier, PGE, produces 53% of electricity from burning fossil fuels and only 22% from hydro: http://www.portlandgeneral.com/our_company/corporate_info/how_we_generate_energy.aspx<br /><br /><br />Also see page 27 of this report: http://www.oregon.gov/ENERGY/docs/reports/legislature/2011/energy_plan_2011-13.pdf?ga=t<br /><br />Furthermore, I have a hard time believing anyone with a remote understanding of the negative social and environmental impacts caused by damming the Columbia River Basin would consider this a green or environmentally friendly electricity source. <br /><br />PHPP does provide a PE benefit for PV and solar thermal. Check page 166 of the 2007 PHPP manual for the PE factor used for solar (0.7).Skyhttps://www.blogger.com/profile/09630190467441992075noreply@blogger.comtag:blogger.com,1999:blog-8663649353921416105.post-43285348540018855642012-03-18T20:19:38.134-07:002012-03-18T20:19:38.134-07:00The Passive House standard caters to the German-Au...The Passive House standard caters to the German-Austrian climate. In France, the Effinergie standard is similar, but offers different weightings for regions, easing energy demands as you head north.<br />At the recent Passive House Northwest a fellow from deep in Alaska revealed his Passive House, a great achievement.<br />Although it does make sense to compare buildings through their primary energy consumption, it doesn't compare their actually efficiency. This is the strength of a unified standard, despite all its drawbacks.Jessehttps://www.blogger.com/profile/02273424810521275539noreply@blogger.com
