How many miles per gallon do electric cars get?

Electric cars aren’t powered by diesel or petrol, so they don’t have an official miles per gallon figure. That said, there are ways of working out how efficient they are and even give them a rough miles per gallon.

How Many Kilowatt Hours is in a Gallon of Petrol? ⛽

The US governments fueleconomy.gov website calculates 1 (US) gallon of gasoline is equivalent to 33.7 kilowatt hours of energy – or kWh.

A US gallon is 3.785 litres, whereas in Canada and the UK a gallon is 4.546 litres. This means a (UK/Canadian) gallon of petrol is equivalent to 40.5 kWh of electricity.

Each litre of petrol is equivalent to 8.9 kWh.

Toyota Prius vs Nissan Leaf MPG

The Toyota Prius was once regarded as the sustainable choice for environmentally conscious drivers, but in recent times its crown has slipped a little. This might be partly because of Toyota’s inaccurate branding, claiming that it sells “self-charging cars”, when in reality a (very small) battery is charged by recovering motion which was achieved by burning petrol or diesel. That’s how most cars charge their 12-volt battery, it’s not self-charging! 😂 It’s also because electric cars are now more viable and mainstream.

The Nissan Leaf is currently the top-selling electric vehicle of all time (at least until the Model 3’s first quarter sales are released) so let’s use that for the comparison. An “efficient” hybrid vs an electric vehicle, how do they compare?

The Nissan Leaf

The Totoya Prius achieves 62.4mpg (UK/Canada) using 4.5 litres to travel 100 miles. The Nissan Leaf by comparison achieves the equivalent of 129.7mpg (UK/Canada) taking just 2.2 litres to travel 100 miles.

This highlights the efficiency of electric vehicles.

The Leaf uses less than half the energy of the Prius (the previous “gold standard”) to travel the same distance.

Efficiency

Internal combustion engine (ICE) powered cars convert around 12-30% of the petrol or diesel they consume into forward motion powering the wheels. This is because an ICE car loses over two-thirds of its energy through heat 🔥 and the transmission of power through the drivetrain.

Even the most inefficient electric vehicles translate at least 60% of the electricity stored in the battery into forward motion. If driven using regenerative braking (to re-capture energy, rather than scrubbing it off via breaking) EVs can be around 90% efficient!

How Big is an Electric Car’s Fuel Tank?

Here’s another interesting question, if an electric car had a fuel tank, how big would it be?

The Tesla Model 3 Standard Range Plus has a 50kWh battery, so if one US gallon of gasoline/petrol is equivalent to 33.7kWh, then the Tesla Model 3s equivalent petrol fuel tank would be 1.48 US gallons – or 5.62 litres.

That’s right, an electric car can achieve a range of 200 miles (275 if driven carefully in warm weather) on less than the equivalent of 6 litres of petrol!

You can also compare cars on a cost per mile basis, which is what I’m going to write about next, with the help of the new electric Mini!

Track Santa this Christmas Eve with NORAD

Today is Christmas Eve, which means that billions of people around the world will be celebrating Christmas tomorrow. Different people of different cultures celebrate Christmas in different ways; some celebrate today, many tomorrow, and others over a twelve day period.

About Santa

If you live in the Britain, France, the USA, Russia, Germany, Canada, Australia, or a (big) handful of other countries around the world, then you are probably familiar with the character of Santa Clause, or Father Christmas.

Christindl, Pere Noel, Santa Claus, Father Christmas, Saint Nicholas or whatever you call him, is a man who lives at the North Pole and sets out to deliver presents to good children across the world on Christmas Eve.

Good children will go to sleep on Christmas Eve and in the morning awake to find their stocking full and presents underneath the Christmas tree, courtesy of Santa. In return Santa asks only that children are good, and he uses information that robins relay to him to decide whether a child should go on the naughty list, or the nice list – he checks each list twice, just to be sure!

Track Santa With NORAD

This year, why not track Santa on his journey around the world with NORAD? Every year, the US military undergo a massive operation involving countless jets, radars and satellites to follow Santa on his journey, for the benefit of children everywhere, and to make sure that he doesn’t run into any difficulties.

NORAD Track Santa logoFrom December the 24th every year, you can track Santa thanks to NORAD. You can follow his route, watch videos as he completes parts of his journey, and learn about the different places he visits. As I write this Santa is over New Zealand, and has just visited Christchurch.

What are you waiting for? Track Santa now!

Remember this Christmas Eve to put the fire out before you go to bed, and to leave some milk/bear and a mince pie out for Santa, and maybe some sprouts or a carrot for the reindeer.

Merry Christmas all 🙂

Good blogging practice – publishing reliable information

The web is massive bank of data, which is far too big to be regulated. Because the web can’t be regulated, it is very easy for false information to spread – fast.

If you are a blogger, it is really important that you publish information which is reliable and trustworthy. Don’t copy what the crowd says unless you know they are right, as this is not only misleading to your readers, but can also see you get penalties dished out from search engines. If you get a reputation for publishing unreliable content, the likelyhood is that your readership will fall.

When you publish something that you have found out elsewhere, you need to make sure that it is accurate and reliable, before you publish it.

How to Mythbust Rumours

When you find information, on the web, in order to ensure that it is reliable, it is always a good idea to check that it appears elsewhere. A general rule of thumb is to check that what you are reading is the same on 3 other sites, one of which is a highly reputable site.

So what is a reputable website?

Government Websites

There are a few way so to identify if a site is reputable or not. One way is to see if it is a government website. Any site which is government run is likely to be very reputable. Government websites usually end in their own unique domain name extension. If you live in the USA, government sites end in .gov or .fed.us, in the UK .gov.uk, in France .gouv.fr, .gc.ca for Canada, India’s extension is .gov.in and the list goes on.

Major News Corporations

Government sites won’t always report things that you want to verify though, so there are other ways to tell a reputable sites. Big news websites like BBC.co.uk/News and Guardian.co.uk will usually only publish information that is factual and accurate, so you can usually trust them.

The Guardian's logoThe information they publish is likely to be accurate, however it may not be impartial, so that is something to watch out for. Often news firms will take a political side, and therefore report news in a certain way – and may only publish part of a story.

High PageRank Sites

Google PageRank is calculated largely by the number of backlinks a page or site has. If a website has a very high PageRank (6+) then it is likely that it has a lot of other sites linking to it, most probably because it publishes a lot of high quality content, which people find useful and therefore link back to. High PageRank sites aren’t always trustworthy, but the higher up the spectrum of PageRank you go, the less likely it is that a site is going to be providing false information.

If a website is a PageRank 8, 9 0r 10, unless they have manipulated Google’s algorithm (through black hat SEO, which will only work for a short while, before Google catches them) then the site is likely to be extremely reliable and reputable, therefore you should be able to trust the information, data and facts that they produce.

1,000,000 to 1

If 1 highly reputable site is saying one thing, but 1 million other (not reputable) sites are saying another another, then the chances are that the 1,000,000 sites are just recycling the same false information, creating a massive bank of false information. This is one reason why you should be really careful who you trust on the web, and also make sure that you verify information with at least one reputable site. Be careful who you trust.

Academic Research

Verifying information with at least 3 sources, one of which is reputable is something which is also advised in academic research. Therefore if you use the same standards on your blog, you can’t go wrong! Search engines and readers alike will respect you for providing good quality, highly reputable content.

Technology Bloggers Policy

Every time I write an article and quote information/statistics etc. I always try to follow the 3 and 1 rule: check the information appears on 3 other sites, at least one of which is ‘reputable’. This means that everything I write should be reputable.

The post guidelines ask all writers to ensure they use the 3 and 1 rule, however we cannot guarantee that all writers do. In our Privacy Policy, we state how we try to ensure all content is true and factual, however it is always advisable to independently verify information for yourself.

Do You Verify Your Content?

Do you always try to ensure that you use the 3 and 1 rule when publishing information? That not only applies to blog posts, but also to comments. If not what measures do you use, or don’t you think it really matters?
