How engineers are solving the world’s biggest problems

From infrastructure to recycling, energy to sustainability, engineers are at the core of solving all the problems of tomorrow and the world knows it

At the 2019 World Engineers Convention a declaration was signed to give engineers a clear directive on their role in making global changes for a sustainable future. The UN Sustainable Development Goals (SDGs) aim to tackle poverty, climate and environment – and engineering skills in civil, design, biomedical and renewable energy will make all the difference.

Locally engineers are feeling the love, too. In October 2020 the Australian Government forked out $2.47 billion to help find ways to lower energy costs and reduce emissions. From this bumper cash injection into renewables, $43 million has been allocated specifically to engineering research.

A problem shared…

From solving energy issues by recycling and expanding battery usage, to finding global warming solutions, engineers are all over it.

Tapping into solar? Associate Professor Deepak Dubal, from QUT, reckons the motion of sea waves is a winner. “Whatever we generate and move, we can convert to some kind of energy.”

Good health systems and finding solutions fast is where biomedical engineers step up to the plate (hi COVID-19!), and civil engineers play their part, too. Think: irrigation systems for drinkable H2O. Yep! Engineers are pretty important for a great future.
