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?

Electric car battery and powertrain

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!

Some bold predictions for 2030

Hello all!

I’m back!

Just in time to see the year (and decade) out! 😊

I’ve been working on a series on electric vehicles, which I’ll start to publish in the new year. Today though, I’m going to look into the future and make some predictions on what the world will look like 10 years from now.

“Most people overestimate what they can do in one year and underestimate what they can do in ten” ― Bill Gates

In 2019, 2030 may seem really far away, but today, we’re closer to 2030 than we are to 2009.

Here are three bold predictions I believe stand a very real chance of coming true over the next decade.

95% of Global New Car Sales Will Be Electric

A decade ago, there weren’t any serious electric cars available on the market. If you played golf or delivered milk, you might use a short-range electric vehicle, but if you wanted to drive 400 miles at 70mph, it just wasn’t possible.

In 2012 the Tesla Model S arrived, as did the Supercharger network, which meant you could drive for 250 miles, stop for forty-five minutes on a 72kW charger and then drive another 150 miles, powered 100% by electricity!

This seemed like a breakthrough at the time, although today cars are available with almost 400 miles of range, and charging takes a fraction of the time, with some networks offering speeds of 350kW – juicing up at well over a thousand miles per hour!

Range has been creeping up, charging speeds rapidly improving and prices have dropped significantly. It’s now possible to pick up a second-hand 100-mile range Renault Zoe or Nissan Leaf for less than £7,000! Alternatively, the 2020 Renault Zoe will have a 200-mile range and cost around £25,000.

EVs require less maintenance than petrol and diesel-powered cars, and are significantly more efficient and cheaper to run – reducing the total-cost-of-ownership. It’s this, coupled with the push for cleaner air and global climate concerns that lead me to believe that the tipping point for electric cars is coming very soon. By 2025 I believe more than 50% of new car sold in Europe, North America and China will be powered solely by electricity. 🔋⚡🔌🚗

Humans Will Set Foot On Mars

In the 1960s there was a great race for space – with Neil Armstrong setting foot on the Moon in 1969. Since then, the dash for extraterrestrial exploration has slowed somewhat, which fewer advances and less drive from governments to get into space.

A notable exception is the ISS, which is celebrating 20 years in orbit – having been permanently manned since November 2000.

NASA has plans for a sustained lunar presence from 2028, something that’ll be much easier thanks to booming interest from the private sector. Rocket Lab, SpaceX and Blue Origin all have ambitious space plans, and a proven track-record of success.

Arguably the most iconic moment of the decade for space travel came as private enterprise SpaceX launched of its Falcon Heavy, simultaneously landing two Falcon 9 boosters.

Mars and Earth are close (in space terms!) every 26 months, meaning roughly every two years, there is an optimal launch window open for a trip to the red planet. The 13th of October 2020 is when the two planets will next be closest, although it’s highly unlikely a manned mission will be launched by then.

The last window of the next decade will the March 2029, which is when I’m guessing the first human will set foot on the red planet – 60 years after Neil Armstrong set foot on the moon.

While the first human to set foot on Mars will probably go straight from Earth, I believe a permanent lunar base will mean that most missions to Mars post-2040 will launch from the Moon, not Earth. This is because it’s likely to be far cheaper to conduct smaller launches from Earth and bigger ones from the Moon – due to the lower gravity.

If the moon has the resources needed for rocket fuel (ice at the poles which can be broken down into hydrogen and oxygen) and to make materials – via 3D printing – in future it could become the springboard to space! 🚀

10 Countries Will Be Cashless

More and more transactions are moving online. When you check-out your virtual basket of goods on the internet, you don’t have the option to pay with cash – one example of how notes and coins are less useful than they once were.

Sweden is expected to go cashless in 2023 and in many developed nations, the use of cash as a means of paying for things is dropping. In the UK, cash was king, accounting for 60% of all payments in 2008 and remaining the single most popular way to pay until 2017 – since then debit cards have been the most popular way to pay.

By 2028, UK Finance believes debit cards, direct debits and credit cards will all be more common ways to pay than cash, with cash accounting for only 9% of payments. The drop from 60% to 9% in two decades shows the scale of the decline.

Singapore bus with a contactless payment reader

On a recent visit to Singapore, it struck me just how far ahead it is in terms of payment methods. Everywhere I visited supported some form of virtual payments; from contactless on the MRT and in-app payments for taxis, to online payments for the hotel and card payments at a 7 Eleven.

Mobile banking, cryptocurrencies, online shopping and contactless technology all offer convenience and are alternatives to support a cashless future.

Naturally, in many parts of the world, lack of development and technological literacy, as well as nostalgia, habits and cultural preferences, mean cash will remain on the global stage for a while yet.

I do think around 5% of the world (10 countries) will become cashless in the next decade though – with Singapore and Sweden both likely candidates. 💷💳

Happy New Year! 🎆🎇✨🎉🎊

Win a Solar Go Go Car to celebrate The Future Car Challenge

Petrol cars have no future. That is a fact, in 50 years time there will be no crude oil left on planet earth (assuming current consumption rates don’t decrease) therefore there will be no oil left to make petroleum or diesel.

Biofuel, hydrogen, LPG and electric cars are the future, there is no doubt about that. Right now there are many hybrid cars which use petrol with another power source, but in the future, petrol from natural oil will be no more.

There are of course other ways you can power cars, using compressed air is one method as is water-cell technology. These are not however currently concepts in mass production. If you follow those two links, you will find posts written by Jonny on the concepts mentioned.

Arguably the greenest option for the future is electric cars. The electricity used to power the cars can be generate from renewable sources, (it isn’t necessarily, but that is an option) and electricity from renewables is a lot less damaging to the planet than energy generated from the extraction and burning of fossil fuels – be it in on the micro scale inside an engine of a car, or on a macro scale in a network of power stations.

Electric cars are starting to look more and more normal, (in the past some have looked somewhat abstract!) and are becoming more efficient every year.

The Future Car Challenge

This year, British Gas (the company who installed Remote Heating Control in my home) became an official partner of The Future Car Challenge. The Future Car Challenge is an annual event, which showcases the latest developments in the electric car industry. This year, members from the British Gas team drove fro Brighton up to London, with the aim of using the least amount of energy as possible, using the latest electric cars. The team included comedian Robert Llewellyn, Ben Collins, (A.K.A. ‘The Stig’), and Commonwealth gold medal swimmer Ross Davenport.

British Gas are setting up a national charging network, to help increase the viability of electric cars. A charging network is as vital to electric cars as service stations are to petrol and diesel cars. Some electric cars do have the ability to transfer energy generate from breaking into electricity, (as seem in Formula 1 cars) however this alone isn’t enough to power them, so electric recharge points are essential.

Here is a statement from British Gas on their involvement with electric cars:

The Future Car Challenge Robert Llewellyn

“British Gas is dedicated to making the world a more sustainable place now and in the future. We are leading the way in providing expertise and charging solutions in the Electric Vehicle market through partnering with Nissan, Renault, Hitachi Capital, Toyota and Vauxhall.

British Gas’ dedicated charging solutions are safer, convenient and more compatible than plugging electric vehicles directly into the mains supply socket at home. Not only do we offer charging solutions that can cut charging times by around a third, but British Gas also offers its customers specially designed tariffs to help them charge for less.”
