One of the ways of reducing our greenhouse emissions is to start using biofuels - biodiesel made from vegetable oils or animal fat, or bioethanol from sugar or (ideally) fermented cellulose. I'd been expecting to see this introduced to New Zealand only after the government set a target to create a market. But someone seems to have jumped the gun. Gull Petroleum will be introducing a B20 blend of biodiesel by the end of the year. They already sell it in Australia, and it retails for up to three cents a litre cheaper than mineral diesel. I guess the market is providing after all.
On the downside, they make their biodiesel from palm oil, which depending on where they get it from, may be a very environmentally unfriendly source...
oils like palm oil and tallow are needed for consumer uses. And the demand for these things is likely to rise it is quite possible it will outstrip petrol.
