They actually don't use the fund to subsidize it. And many policies were added overtime, which any managed economy should be able to do.
The Norwegian EV incentives:
No purchase/import tax on EVs (1990-2022). From 2023 some purchase tax based on the cars’ weight on all new EVs.
Exemption from 25% VAT on purchase (2001-2022). From 2023, Norway will implement a 25% VAT on the purchase price from 500 000 Norwegian Kroner and over
No annual road tax (1996-2021). Reduced tax from 2021. Full tax from 2022.
No charges on toll roads (1997- 2017).
No charges on ferries (2009- 2017).
Maximum 50% of the total amount on ferry fares for electric vehicles (2018)
Maximum 50% of the total amount on toll roads (2018-2022). From 2023 70%
Free municipal parking (1999- 2017)
Access to bus lanes (2005-). New rules allow local authorities to limit the access to only include EVs that carry one or more passengers (2016-)
25% reduced company car tax (2000-2008). 50% reduced company car tax (2009-2017). Company car tax reduction reduced to 40% (2018-2021) and 20 percent from 2022.
Exemption from 25% VAT on leasing (2015-)
The Norwegian Parliament decided on a national goal that all new cars sold by 2025 should be zero-emission (electric or hydrogen) (2017).
«Charging right» for people living in apartment buildings was established (2017-)
Public procurement: From 2022 cars needs to be ZEV. From 2025 the same applies to city buses
Meanwhile in Slovenia - here, have some subsidy for buying a new one and that's all. Figure out yourself about charging, specially if you live in an apartment.
It's no different in Sweden. While I'm on my second EV and will never go back I can't motivate it for people who live in apartments. To be able to use an EV effectively you absolutely have to have your own charger to connect it to while home, and very few apartments have that possibility.
Norway has way more incentives compared to us, which is somewhat unusual between us Nordic countries.
Pretty much all apartment buildings built in Norway nowadays have ev chargers built into the parking lots / garages. With a lot being retrofitted as we speak.
Yea, I can envision public parking spots around apartments having slow chargers - 8kW something, so the cars can be charged over night for a similar price you have at home. However, that would required government motivation (wisdom) first and upgrade of electricity network which isn't able to sustain such power. Neither is happening, not even plans. Our governments suck. Funny aspect is that Slovenia is a small country (2M population) and could serve as testing ground for such experiments. I won't even mention basic income...
And a lot of smart investment, see the UK for an example of a country that got a 50% share in the exact same oil fields and continues to run itself into the ground to pay oligarchs.
