There are so many 12-volt gadgets these days – made for cars, RVs or boats that you can get anything from a stereo to a washing machine in a 12-volt variety. But this excellent book is overstating it by calling itself “A Do It Yourself Guide.” After reading it, I would be more inclined to hand it to an electrician and tell him, or her, to follow the complex diagrams. When it comes to wiring a 12-volt set-up you need to be extra careful to use the right kind of extra-thick cable, because 12 volt cables become very hot and can cause fires. You also need to be careful you get your positive and negative wires the right way around, or you can cause battery explosions and fires.
And this is a guide to solar power, whereas you might want to use wind, or hydro depending on where you happen to live and what is available. Finally, you can apply some of these prinicples to installing an extra 12-volt power source in your own car or RV/camper van. Tags: off-the-grid, solar, home-, 12-volt, wiring.
Coal Seam Gas: By The Numbers. Updated Thu 28 Jun 2012, 7:27am AEST Produced by ABC Radio Multiplatform & Content Development, and presented by ABC News Online. This data journalism site was compiled in April 2012 and all information contained here is current as of that date. For ongoing coal seam gas stories since then, go here. Coal seam gas has emerged as a major industry in Australia in little more than a decade. The scale and speed of its growth has been nothing short of astonishing: billions of dollars have poured into regional areas; new jobs have been created; state and national coffers have swelled; export contracts have been signed and sealed; massive liquefied natural gas facilities have been approved for construction at regional ports. Farmers fear they are losing control of their land. Miners and some politicians say coal seam gas offers a much greener energy choice. Quick guide How is coal seam gas mined?

No matter how bad coal might be for the planet, the conventional wisdom is that there is so much of it underground that the world’s leading fuel for electricity will continue to dominate the energy scene unless global action is taken on climate change. But what if conventional wisdom is wrong?
A new study seeks to shake up the assumption that use of coal, the most carbon-intensive fossil fuel, is bound to continue its inexorable rise. The study, led by Tad Patzek, chairman of the Department of Petroleum and Geosystems Engineering at the University of Texas at Austin, and published in the August issue of Energy, predicts that by mid-century, the world's coal mining will supply only half as much energy as today. The idea that the world will face "peak coal" as soon as 2011 flies in the face of most earlier estimates and analysis. (Related: “The High Cost of Cheap Coal”) The Great Energy Challenge.
