    Check out τι γίνεται και στην άλλη πλευρά του Ατλαντικού: http://www.dailytech.com/Detroit+Hosts+First+Conference+on+Plugin+Hybrid+Vehicles/article16544.htm http://www.detnews.com/article/20091018/AUTO01/910180310/1148/auto01/Detroit+conference+to+focus+on+plug-in+electric+vehicles Είναι επίσης αρκετά ενδιαφέροντα και τα σχόλια των αναγνωστών, όπως φαίνονται στο τέλος του άρθρου,όπως: quote: The grid needs updating and if we're going to plug in and not fill up, we're going to need a ----load of additional electricity. This is one of the biggest misconceptions ever. Lets start with the following http://www.epa.gov/OMS/climate/420f05004.htm Appears a per passenger vehicle the average number of miles is 12,000. The Volt claims 4 miles per kWh from the wall. Seems optimistic. Lets go with more realistic 3 miles per kWh average. So 4,000 kWh per passenger auto per year (4 MWh). There are 128 million passenger cars on the road roughly. (BTW, it would take more than 20 years to replace them all, even if we started selling only electric today). If all 128 x 10^6 cars converted today, we would require 512 x 10^6 MWh yearly. Last year the US generated 4,064 x 10^6 MWh http://www.eia.doe.gov/cneaf/electricity/epm/table1_1.html An increase of only ~12.5%. (Keep in mind, yearly gasoline consumption would go down by a factor ~61.4 Billion Gallons)Converting light trucks might increase this number to 25%. If we assume something on the order of 10 million electric cars/trucks sold per year, thats an increased power requirement of only ~40 x 10^6 MWh, or around 1% currently produced. In 2010, there is approx 120 x 10^6 MWh of capacity coming online, which is fairly typically year to year. How about this "fact". US currently only produces around 50% of generator nameplate capacity. Plenty of slack in the system to provide power for all light cars and trucks - IF- the grid is balanced properly, which is/will be an issue going forward regardless of the electrification of cars. Έτσι για να είμαστε λίγο πιο σφαιρικά ενημερωμένοι.
