A Clean Energy Council report said that Australia produced a record 13 per cent higher renewable energy in 2012 from clean electricity sources such as hydro, wind and solar.

The bulk of the renewable energy or 58 per cent comes from hydro sources, while wind energy contributed 26 per cent and solar 8 per cent.

However, while clean energy production expanded, investment in renewables dipped by $1.3 billion last year to $4.2 billion from $5.5 billion, said David Green, chief executive of the council.

The investments went down as the government incentives to install rooftop panels were removed. It is a similar trend in renewable energy investments globally which also declined 10 per cent in 2012.

However, in the European Union, three of the biggest member-states re developing solar power, biomass and other renewable energy technologies, replacing offshore wind power which is still in early stages of commercialisation and more expensive.

In the U.S., Washington state uses the more renewable energy with hydroelectric dams providing more than 60 per cent of the state's energy requirements.

Besides the push for cleaner sources of energy, Australians are blessed to have pristine water sources amid the discovery this week of an untouched body of water which one scientist referred to as God's bathtub.

The lake is said to be untouched by the negative impact of climate change with water so clear and its chemical condition almost the same over 7,000 centuries ago.

Blue Lake is located in a remote area and its clarity could be gauged by the bottom of the lake clear from the top despite being 35 feet in depth. It is found on North Stradbroke Island, off south Queensland coast. It is the subject of a project by University of Adelaide researchers.
