My vote looking at the benefits / Disadvantages:
Electric for small vehicle/private use.
Hydrogen or Bio fuels for commercial (truck, ships, planes)
scuwp:
Disagree. Electric engines definitely, but not battery powered. I consider that battery as a fuel source has a 10 - 20 year lifespan max, unless we can resolve issues around charging time, range, precious metals mining, and environmental impacts from production and disposal. We are already seeing fields of abandoned EV's in some countries and stockpiles of batteries that are an environmental disaster waiting to happen if we don't figure out a sustainable environmental plan from start to finish.
Except this isn't really true and that is classic and long disproven anti EV propaganda, much of which leverages the general publics habit of projecting their ICE experiences/preconceptions onto EV's.
1 - ICE only has a design life of 10 years (yes broke kiwi's milk this out a bit longer) so a battery lifespan of 10-20 years is no deterioration. Lithium battery recycling isn't common because the raw feed stock (dead batteries) doesn't yet exist in commercial quantities. The preconception exploited here is that they're not recycled because it to technical/expensive. On the other hand, there are rubbish dumps full of ICE's in excess of commercially practical quantities.
2 - precious metals = cobalt is the metal of choice for the nay-sayers and modern batteries (eg Tesla) have dramatically reduced the cobalt needed and are on track to eliminate it entirely (for instance with silicon). Gadgets such as phones and computers are consuming greater volumes of precious metals, such as gold, and will continue to do so due to their shorter life span (3 years vs 10-20 years), and greater prevalence (everyone has multiple gadgets but only 0.25 cars). Lithium isn't "mined" out of holes in the ground contrary to popular propaganda (except for one place in Australia), it is precipitated out of salt water in a similar way to making salt out of salt water, and is very abundant on earth.
3 - Within 5 km of you there will be a field full of dead ICE cars and we recycle those just fine. I challenge you to point out this field for of dead EV's in NZ.
4 - Charging Time. The preconception is that you have to actively wait for EV's to charge, just like you actively wait for your ICE to full up with gas. In reality, EV is like you phone, you plug it in when you go to bed, and 95% of the time, you don't actually know or care how long it takes to recharge, you only care that it is full in the morning. Also, because recharging is no inconvenience, most EV drivers don't put it off until the "tank" is empty like an ICE - it takes 9.75 seconds to plug it in so they do, even if that battery is still got 40/50/60% left in it. Most EV owners spend a lot less time charging their EV's than they previously spent on petrol station forecourts in the past.
5 - Range: Firstly 90% of people travel less than 60km on a daily basis so big range isn't a practical necessity for most people - this plays upon the supposed/projected/entirely theoretical inconvenience of actively waiting for recharging. Secondarily, ranges of over 400 km in EV are pretty common now, which is greater than the range of most peoples bladders and pretty close to ICE, plus EV's continue to improve. You buy a car suitable for the journeys you make every day, and compromise on the once a year journeys, irrespective of fuel type. If we didn't compromise we'd all be driving, flying, amphibious 6X6 buses with a 10 tonne towing capacity.
