solar power queensland government

Why did not he, t of Queensland and Australia's government to install?
rainwater tanks, gray water irrigation systems and solar panels in their propeties. If the Housing Department implemented these products Iam sure there would be a dramatic improvement of the current situation. If solar is held here our complex would generate enough energy in one day to last us a week!
How many houses actually build housing department or own? Would it actually fesible to install these features or is likely to obtain vandalized or destroyed very quickly? To be honest I have no idea …. perhaps because the government has a poor environmental policy, or one that is not very realistic and ambitious?
