insane_alien Posted August 7, 2005 Share Posted August 7, 2005 How much electrical energy will an average RV consume every day? simple question. I would prefer the answer in joules but any unit of energy would be fine since i have a really big calculator and a conversion chart. Link to comment Share on other sites More sharing options...
mezarashi Posted August 7, 2005 Share Posted August 7, 2005 Sorry, but what's an RV? *blink*blink* Link to comment Share on other sites More sharing options...
H2SO4 Posted August 7, 2005 Share Posted August 7, 2005 mezarashi, an RV is a "recreational vehicle" pEOPLE TAKE TEM CAMPING...the big things, in other words, a motor home. That is a good queston, how much do these things consume. I dont know enough to give a good guess though. Link to comment Share on other sites More sharing options...
insane_alien Posted August 7, 2005 Author Share Posted August 7, 2005 i found loads of figures on the internet but most of them are ridiculous i seen one that was 38J per day! although that may have been a typo as it seemed a credible source.

mezarashi Posted August 7, 2005 Share Posted August 7, 2005 I thought it referred to a vehicle, although I thought it would be more logical if the question would be asked as, how much energy does it consume per liter instead of per day, because that would have to depend on how much you drive it around, and what model (different fuel consumption rate). Thus I had to make sure. I guess if you needed to make an energy consuption estimation, the best way to do it would be through it's fuel consumption. Some rough figures I've found on the internet say that for each liter of benzene combusted, you will get 42 Mega Joules of energy. Compare that to the 8 MJ daily energy intake humans need and that looks like it makes sense. Well this isn't the real useful energy it consumes. I'd guess around 20-30 percent of that 42MJ is actually used to drive the car and batteries. The rest probably goes to waste as thermal energy or goes out with the exhaust. If it were an electric car with a far more efficient propulsion system, then I'm sure it'd use far less. Any other sources or methods? Link to comment Share on other sites More sharing options...
H2SO4 Posted August 7, 2005 Share Posted August 7, 2005 The main source for rv's is a small, propane or gasoline generation. They probaly pump out 1000watts Dont know if this help or not... Link to comment Share on other sites More sharing options...
insane_alien Posted August 7, 2005 Author Share Posted August 7, 2005 why per litre? i probably should have mentioned that its electrical consumption while parked and being used as a home, not being driven around. I know this depends on what you have hooked up to the electrical supply but i'm just looking for an average. the generator gives me a rough guestimate on the consumption but ithink some of that would go into the batteries and that the generator would not be run permanently.
