Obama satsar på hybridbilar

Elbilar och el/förbränningsmotorhybrider. Gas/Elhybrider diskuteras lämpligast under forumet Gasfordon.

Obama satsar på hybridbilar

WASHINGTON, DC — The federal government will order more than 5,000 hybrids this year, doubling the size of its hybrid fleet to more than 11,000.

The U.S. General Services Administration (GSA) will also buy about 100 plug-in hybrids in 2011, President Barack Obama said today as part of a larger announcement on his broad energy security strategy.

Vad är 100 pluginhybrider i USA? I stort sett ingenting.

Det hade varit annorlunda om han sagt att det amerikanska postverket beställde 20.000 pluginhybrider på ett bräde.

För det skulle de kunna göra.

Jo. Det är väl inget nytt.

Men en elbil (hybridbil) som får sin el från ett kolkraftverk blir ändå ett bra klimatalternativ tack vare att elbilens elförbrukning är så låg.

"An electric car's efficiency is affected by its battery charging and discharging efficiencies, which ranges from 70% to 85%, and its engine and braking system. The electricity generating system in the US loses 9.5% of the power transmitted between the power station and the socket, and the power stations are 33% efficient in turning the calorific value of fuel at the power station to electrical power.[15] Overall this results in an efficiency of 20% to 25% from fuel into the power station, to power into the motor of the grid-charged EV, comparable or slightly better than the average 20% efficiency of gasoline-powered vehicles in urban driving, though worse than the about 45 % of modern Diesel engines running under optimal conditions (e.g. on motorways)." http://en.wikipedia.org/wiki/Electric_car

Jo, men sedan har Du ju också att förnyelsebar el och kärnkraft ökar i USA och de som propagerar för elbilar i USA säger ofta att de kan gå på vindel, vilket naturligtvis delvis kan vara sant.

Har man kol som bas kan man också antingen göra el till elbilar (med 20% total effektivitet) eller bensin till bensinbilar (med 7% total effektivitet). Dvs. den dag man framställer bensin ur kol på samma sätt som SASOL i Sydafrika.
