We threw caution to the wind and put in a couple of solar systems. Above, is the solar collector for hot water. Now, it has been pretty cloudy since they went in (figures!) but the temperature water in the tank is in the 40s. (That's deg C. It's in the 70s for those of you who still use ancient units.)
Attached to the storage tank is a small gas heater that boosts the water temperature by the required amount as it enters the house.

Meanwhile, up on the roof are a dozen panels for electricity. They work (so I'm told) but cannot be connected until a 'bidirectional' meter is installed. AGL, if you are reading this, I am waiting, waiting...
Combine all that with a hybrid car (4.9 L/100km on a trip to the country and back last weekend.), a new 6 star fridge, four water tanks and a vegetable garden, we are doing pretty much as much as we can.
