Bushfires in Tassie – photo: flickr/ToniFish
As I sit here writing this week’s rant, we are (it seems) in the middle of one of the worst heatwaves ever to strike the continent. Characterised by indecently high temperatures, bushfires and breathless “on the spot” news reporters, the harsh weather is crossing the land from west to east, north to south. [Read more…]
Solar Hot Water is fast becoming the poor cousin of Solar PV (AKA Solar Electricity). Consumers just seem to prefer solar PV to solar hot water these days. In fact solar hot water has gone from almost zero to 1,000,000 roofs in about 30 years, whereas PV has gone from almost zero to 1,000,000 roofs in less than 6 years. There is now more PV than Solar HW out there! Unbelievable.
It doesn’t help that retailers prefer to sell PV over hot water – for a whole bunch of reasons that I’ll go into in a future blog post.
Here’s a video where I answer the question posed in the title: Should you buy Solar Hot Water or PV first?, But first I answer a much more fundamental question that creates an enormous amount of confusion out there:
And here’t the transcript for the video-phobes amongst you: [Read more…]
Vast solar arrays in the middle of our hot baking deserts or mainland cities awash with solar panels are generally considered the most efficient way to soak up the abundant sun for energy in our country. In terms of suitability for solar farms in this wide, brown land of ours, the mind definitely points to swelteringly hot parts of the mainland, rather than the cool, fresh, green island of Tasmania.
Not so according to a recent study by the American Chemical Society journal Environmental Science & Technology which says the cooler regions of the world are, contrary to general belief, an excellent area to generate massive amounts of solar energy. The report says that cool climates, particularly those at a higher altitude, have massive potential to generate solar-powered electricity.
The Victorian parliament is set to vote in the new feed-in tariff laws as early as Wednesday. The proposition of this legislation has angered a great deal of green campaigners and supporters of renewable energy.
