Electric Car running costs.

[Rupert]

A number of friends and aquantances have been buying up electic cars and hybrids over the last few years, and always talk of the free miles on electric.  We all know its not free, but it is miles without having to fill the conventional tank.  That gives them absurd mpg figures if they have a short run to work.

While trying to get my Outlook file to do a simple thing as "search the emails" this morning (and failing), I got side tracked into this simple calc. 

An electric van averages 0.3kwh per mile:

(220 mile range with 67kwh battery.

In the UK, I am paying 27p per Kwh at the moment, which is about 10p ($0.1 per mile)

But the DEPENDABLE range is only 100 miles.... so 20p mile

My Van does just short of 10 miles per litre (45mpg)  Its a van... not sure how it compares to a Nissan leaf, but bear with me.

At £2 per litre of diesel at present, that is 20p per mile. 

Where is the saving now?

Doesn't look good, and 27p kWh is not bad nowadays. Wholesale price today is about that, so your energy provider is likely making a loss https://www.energy-stats.uk/wholesale-energy-pricing/

Octopus Go have a cheaper night period, 7.5p kWh, 35p for the rest of the day. I think the gist of people on that tariff is they're generating with solar and/or have a battery and charge the car overnight. https://www.energy-stats.uk/octopus-go-versus-agile/

I think most are misguided as to the savings, and  in the case of one family, the wife is a teacher, so can fill up for free at work. So free to her but not society.

Good to know I am on a cheap tariff, still seems expensive to me !!!!

On a similar vein, I have just replaced my old fridge and freezer. they are using a combined £270 of elec p.a. At 25 years old (actually over) they owe me nothing, and modern kit claims to run on an equivalent £110 p.a, saving £150 p.a. 

Current costs that a 10 year pay back, but the new ones are quieter, have more space, are frost free, and claim to keep food fresh longer. so we took the plunge on that one.

It all started with https://www.emporiaenergy.com/

Energy monitor. I have not tied it to hubitat (not sure its possible even) but we have pulled in some considerable leakage.

Today's tariffs are definitely more - comparison sites are looking scary at the moment. Makes the sums of replacing your fridge freezer much more economical for pay back. I did the same with a heat pump tumble dryer, it should pay for itself within 5 years. Also replaced an older TV (300W/h vs 75W/h)

It doesn't look great for leccy car owners if they're not generating their own or storing cheaper overnight energy. Hopefully it's windier this autumn to take the edge off the wholesale price.

That comment made me look at this.  not looked for a while. Not a lot of pumped hydro. I wonder why?

Also currently we are importing from NL, and exporting to France.

I think they tend to use hydro during peak demand, 4-7pm. My supplier has a tariff that has a multiplier for these peak times - I guess hydro can be sold for more onto them.

We have a surcharge for 4-9pm.

I think it's a combination of things. Partly, here, it's when solar output drops. But it's also when everyone starts getting home from work and turning up their A/C, throwing in laundry loads, turning on ovens for dinner, taking a shower and so forth.

During that period, California has to fire up it's natural gas boilers to meet the peak demand.

>> throwing in laundry loads

My washer has a timer so I can put in a load when I have the time  but run it later. I wish my dryer had the same feature!

I am sure you could do it with hubitat.  _{(It needs to run from turn on, so might actually not work, unless its very old.)}
