Very glad people are taking approaches to investigating the broader effects of alternative energy sources - and very happy that they’re showing positive results for these alternatives.
For the first time, researchers have taken an overall look at Swedish biofuels and analysed what impact they have on the environment, both in relation to one another and to the fossil fuel alternatives petrol and diesel. The results show that they produce between 65 and 140 per cent less greenhouse gas emissions than petrol and diesel, even when direct and indirect land use changes are taken into account.
Thus the report pokes holes in a controversial argument against biofuels produced from food crops, [namely,]… that these do not have any climate benefit because they crowd out food production and so force new land clearance for cultivation of food in other countries instead… “Our results do not indicate that biofuels produced from crops grown in Sweden currently lead to indirect land use changes.. Despite this, a number of economists have claimed that it could take 50 years for biofuels to repay their impact on the climate, specifically as a result of indirect land use changes,”…
