Why Battery is better than Hydrogen

Australian Research

Low energy efficiency is already a major problem for petrol and diesel vehicles. Typically, only 20% of the overall well-to-wheel energy is actually used to power these vehicles.  This low energy efficiency is the primary reason why fossil fuel vehicles are emissions-intensive and relatively expensive to run.

The other 80% is lost through oil extraction, refinement, transport, evaporation, and engine heat.

With this in mind, we set out to understand the energy efficiency of electric and hydrogen vehicles as part of a recent paper published in the Air Quality and Climate Change Journal.

Electric dream: consortium still pushing to bring Formula E to Auckland

A consortium including ASB Classic tennis tournament director Karl Budge is angling to bring "Formula E" racing to Auckland.

He and consortium partner Craig Cotton (head of the NZ Innovation Council) commissioned a study by SMG YouGov that says the race would bring in $150m a year.

Why It's Important

Budge and Cotton say it's not just about the thrill of motorsport. The pair argue Formula E racing in New Zealand would help spur clean energy research and electric vehicle adoption as the government targets a carbon neutral economy by 2050.

Tax the Polluters

Can New Zealand reach Norway's standard for electric vehicles?

Norway has surpassed the rest of us - they have the largest electric vehicle (EV) ownership per capita in the world.

With more than 200,000 plug-in EVs recorded at the end of last year, the number continues to rise as the country aims to sell only zero carbon-emission cars by 2025.

So how does New Zealand compare? Christina Bu is the Norwegian Electric Vehicles Association secretary general and she spoke to The AM Show on Monday.

Moving Right Along

You know things are getting a little crazy when people are calling for taxes on fossil fuels to be cut so we can keep consuming fossil fuels and maintain our trajectory towards climate chaos.

There is actually plenty of good news, and much of it involves the Government. But what can we do ourselves? Up until recently, most commentators thought that petrol demand was "inelastic" - we'd just keep buying it no matter how much it cost. However, the recent price spike saw people boycott petrol stations briefly and Z Energy has reported a 31% fall in profits in the six months to the end of September. People are managing to do with less. The sky did not fall and alternatives to the single occupant car were found. So how about taking a pause to think about our own transport habits and what we could change to reduce burning fossil fuels...

Electric Vehicles Go The Distance

The latest data from Flip the Fleet, a coalition of over 1,150 EV owners from all round New Zealand, shows that electric vehicles are actually driven further each year than combustion vehicles.

The annual average distance travelled across all models of EVs is 14,100 km/year, a Electric vehicles go the distance quarter more than the 11,500 km/year for combustion vehicles.

“Our Trust provides test drives to let people experience what a joy EVs are to drive,” says Kathryn Trounson, Chairperson of The Better New Zealand Trust, “These data show that the switch to electric cars also saves them money while reducing New Zealand’s carbon footprint.”

$150 to Drive Right Around Australia

Sylvia Wilson drove around Australia in an electric car. It cost her $150.90.

Wilson, 70, a retired farmer from near Biloela in central Queensland, had planned the trip of a lifetime with her husband, Rod. One impulsive evening in mid-2016 they went online and, sight-unseen, bought a Tesla S75 electric car for the journey.

A few months after Rod died last year, Sylvia announced to her family: “I think I’ll do that trip.

“Most of them were really keen. A couple of them said ‘you’re mad, you’ll never do it’,” Wilson told Guardian Australia.
