Toggle, solar is here and now.
My whole house runs from solar. This post is typed on a computer powered by solar.
Of course some may argue that clean energy is too expensive. In my opinion, dirty power is too cheap. If renewables got even a fraction of the subsidies given to oil, coal and nuke, we'd all be solar already.
Here in the state of Victoria, we already have mandatory insulation, energy and water efficiency measures. Any new house must have minimum R1.5 exterior walls; R2.0 exterior ceilings; minimum "5 star" overall energy rating when assessed with the state's First Rate software, which awards from 1 to 6 stars for energy efficiency, based on heating and cooling requirements; and either solar hot water or a rainwater tank minimum 5000 litres.
I don't know how to convert USA R-ratings to Metric R-ratings, but as an example 4 inch fibreglass batts typically rate at R2.0 or R2.5. I have 6 inch polyester batts in my celing and they are R3.5.
Water conservation is really getting serious here. Call it drought or call it climate change, water conservation is becoming THE issue here. Last year my partner and I visited two lakes towards the North of the state, Lake Eppalock and Lake Eildon. Both were major holiday destinations up until the 1980s. They are now dry. Lake Eppalock has been below 10% capacity for near 10 years. The hotels around it are empty and being demolished. At Eildon, old farmhouses from 100 years ago which were submerged when the lake was created are now exposed. We drove around the floor of the lake in our little hatchback car, it is dry. As a teenager my hubby used to canoe around the area. The lakes were created for irrigation and town water supply, the farmers aren't getting water and the towns are constructing pipelines to bring water from hundreds of kilometres away, from rivers that are dwindling too. Meanwhile residents are prohibited from watering lawns or gardens, except with water saved from washing or showers. Washing cars is banned too. Luckily we live further South where it still rains, so we are OK but it is much drier now than even 5 years ago.
