The decisions you make today on what heating, cooling and hot water systems you are going to fit to your house needs careful consideration in the face of disruptive energy futures.
The New York Times article below gives an insight into how other countries are already transitioning their energy grids to renewable energy, and the role Germany's policies have had in driving market change in renewables.
Meanwhile natural gas is fast becoming a fossil fuel that is not only made from dinosaurs, but rapidly becoming the fuel dinosaur in the emerging world of clean energy. With natural gas having traded on the fact that it has traditionally been cheaper than Victorian brown coal fired electricity (and also had only around 1/3 of the CO2 emissions), we now believe you should carefully consider the fuel source of the heating and hot water technology you commit to.
Gas is still a polluting fossil fuel, and the recent article in The Age below explains why it is about to lose it's cost advantage as we move to world parity pricing.
While the efficiency of electrical fittings and appliances is improving rapidly (as evidenced by the LED lighting revolution), the cost of electricity is also set to keep increasing into the future as well. The article below from CarbonTel gives an overview of why both gas and electricity prices will continue to increase with our current federal policies.
Now if someone could design and build houses that reduce heating and cooling requirements by 70-80% in the first place . . . . . . .
