Western Australians are concerned about the state’s future energy needs, according to research commissioned by energy giant Shell.

The report suggests that the global population is expected to grow from 7 billion today to 9 billion by 2050, causing energy demand to double in less than a century and placing significant stress on energy resources.

Shell Australia country chair Ann Pickard said the findings aren’t surprising given that over the next 30 years the global energy system will need to undergo a historic transition, with WA to play a key role in the shift.

Natural gas was seen as one of the most preferred future energy sources, while oil and coal were seen as the least favoured energy options.

Across Australia the survey also revealed over one third of Australians believe collaboration between industry, Government and the community will be key to finding the solutions to meeting future energy demand.

“We, industry, the community and Government all have a responsibility to find innovative solutions to meet future energy needs," Ms Pickard said.

"The power of our collaboration will define how successful we will be in addressing the challenges of the future.”
