The International Energy Agency estimates that by the year 2035 there will be 1.7 billion cars on the road.

The International Energy Agency (IEA) estimates that by the year 2035 there will be 1.7 billion cars on the roads.

As you would expect, most of the growth is related to the Chinese market where car sales have boomed in the last few years, a trend which is likely to continue in the years to come. To fully comprehend the growth, in 2000 there were 4 cars / 1000 people, in 2010 there were 40 cars / 1000 people, and while in 2035 there will be 310 cars / 1000 people. In other words, the number of cars in China will grow from today’s 60 million to 400 million by 2035.

Another relevant statistic comes from India where last year there were 14 million cars on the roads, but this number is expected to increase to a whopping 160 million by 2035.

IEA also estimates that by the year 2035 full-electric cars will account for 4 percent of all sold vehicles, while hybrids will account for 20+ percent. In addition, 3 percent of all cars will run on natural gas.

Due to the increasing number of cars, the level of emissions has increased by 50 percent from 1991 through 2011. Although cars are becoming more efficient, this technological evolution will be offset by the large number of vehicles that will be on the roads in the future.

Speaking of roads, IEA estimates that by 2035 there will be an additional 10 million more miles at a cost of $20 trillion.

The estimations are part of the World Energy Outlook 2011. 2012 version released this week.
