Experts from the Australian Academy of Technological Sciences and Engineering have assessed the impact of global warming on infrastructure in the country.

The study report warned that electricity would be hardest hit and more interruptions to supply could be expected.

Drought would slash hydroelectric generation, while hot temperatures would interfere with power plants and increase the demand for electricity, the report said.

More frequent bushfires would interrupt supply, 'The Australian' daily said quoting the report.

Water infrastructure would also suffer because of more droughts across southern Australia and major investment in water was needed to see these regions through extended droughts, it advised.

However, while the south dries out, climate change is expected to bring more floods and storms to the rest of the country - and that poses risks for low-lying buildings and roads in Australia, the report said.

The newer houses are better equipped to withstand the effects of changing climate but older houses, especially near the coast, were vulnerable to flooding and storms.

Even footpaths will be hit by climate change- droughts, floods and hot temperatures can cut their lifespan, it said.
