do we need solar and EV subsidies in New Zealand?

Picking winners or helping losers? Governments of all stripes have offered incentives for businesses and households, some with meaningful success.

the current coalition has backed

the previous Government's GIDI Fund spent

$300M+

to help some of our biggest emitters switch to electricity

the Clean Car Discount took up to

$8,000

off the upfront cost of an EV, back when EVs were expensive, there were fewer choices and it was new(ish) tech

With no Road User Charges as well, New Zealand was well above the global average for EV adoption in 2023.

in the year to July, New Zealand spent

$12.1 BILLION

importing petrol, diesel and other fuels

+$2.3 BILLION

more than the year before. And that's import costs, not retail costs.

current fuel subsidies for 150,000 families cost

OVER HALF

of our total energy is imported

It's a finance scheme, not a subsidy. The Greens have proposed subsidising the interest rate down to 0%.
