"Western Australia is fortunate to have an abundance of natural gas and ready access to liquid petroleum gas and liquid natural gas, which are cleaner energy sources than some alternatives," State Energy Minister Eric Ripper said.

"But unfortunately there are some parts of the State that do not have gas reticulation networks and therefore do not have the choice of connecting to gas."

Mr Ripper added the Government wants to encourage investment in regional infrastructure and greater consumer choice in energy supply.

The Government may have difficulty attracting any investment at all in gas-related projects if the battle between pipeline owner Epic Energy and the State's independent regulator goes on, according to Department of Mineral and Petroleum Resources.

The Full Court of the WA Supreme Court has reserved its decision after a day of arguments by Epic and the WA Office of Gas Access Regulation.

The two parties are trying to finalise orders so the gas regulator can make a final decision on transportation tariffs for Epic's Dampier-to-Bunbury natural gas pipeline.

In other WA energy news, Eric Ripper said he will consider a plan to reduce power consumption of household appliances when in 'sleep' or standby mode.

"This unnecessary power use creates about five million tonnes of greenhouse gas emissions," Mr Ripper. "It is costly to consumers, wasteful and harmful to the environment."

Some of the measures Mr Ripper is considering includes incorporating standby energy consumption in the 'star' rating to allow consumers to compare domestic appliances and conducting annual surveys to benchmark the standby power consumption of products on the market.

State and Federal Energy Ministers meeting today in Brisbane are expected to decide on national strategy to reduce standby power consumption by as much as 75%.
