The pie charts illustrate the amount of four different kinds of vehicles (fully electric, hybrid, petrol, diesel) owned by the Norwegian respondents in 2008 and 2018, and a prediction for 2028.
Overall, the ratio of petrol consuming vehicles drops while the hybrid automobiles have an upward trend. Complete automatic cars appeared in 2018. The same trends will continue for a prediction in 2028 except a predominant value for fully electric cars, followed behind by hybrid, diesel, and petrol cars respectively. Throughout the period the value of diesel cars fluctuates.
For the period from 2008 to 2018,there was an upward trend for the two kinds of cars (diesel and hybrid). The ratio of the vehicles run on diesel saw an increase by 16% over the period; rose from 30% to 46% from 2008 to 2018, which is roughly a 50% increase of the amount in 2008 (at 30%). Likewise, hybrid cars also experienced an upward trend by 1000%: shot up from 1% in 2008 to 11% in 2018. In addition, automatic cars appeared in 2018, which were registered by the citizens of Norway at 4% then. However, the amount of cars consuming petrol dropped down by 30%: from 69% in 2008 to 39% in 2018.
The period from 2018 to 2028, a prediction, shows an estimated increasing trends for fully automatic cars and hybrid cars: 4% to 32% (8 folds) and 11% to 30% (nearly 200%)respectively. In contrast, the proportions of petrol and diesel cars are projected to be dropped dramatically: from 39% to 11% and 46% to 27% respectively.
