Do you still use a gas stove to cook your dinner every night? You're not alone. Almost 70 per cent of Australian households today use gas to heat their homes, cook their food and provide reliable hot water. But as we move into a dramatically changing energy landscape with increasingly critical environmental concerns to consider, we have to ask: what role will gas play in a renewable-focused future?

Video: If watching dry ice sublimate is already one of life's pleasures, what can we call the joy of watching dry ice being submerged in water? Never seen it? Forgotten what it looks like? Well, watch this whole brick of dry ice get stuck underwater and check out how the carbon dioxide gas just bubbles up to the surface while forming a slithery, almost refractive layer around the dry ice. The dry ice almost takes an amorphous shape.
Video: Watching dry ice sublimate (turn into gas instead of liquid) still manages to make me feel like a kid again. The kind of kid who is unsure of the difference between science and magic. OK, not quite ... I'm old now and it's impossible to ever look at things so innocently any more. But when I see the carbon dioxide gas immediately escape the frozen dry ice, I can't help but be entranced. Especially when it's shot up close like this.
For the first time ever, the United States Geological Survey has published earthquake hazard maps that includes both human-induced as well as naturally occurring earthquakes. USGS maps had previously only featured natural earthquake hazards, but thanks to the alarming rise of man-made quakes, the scientific body has now started to track both kinds.
Video: It's flame retardant tinsel (which has absolutely no chance of standing up to the mighty red hot nickel ball), which probably explains why the smoke it releases looks so damn toxic. I mean, the smoke is so thick that it looks like it's a yellow green grey sludge and not actually smoke. Inhaling one puff of that smog's fart must knock you out cold and re-arrange your sense of smell for life.
By 2030 renewable energy sources such as solar and wind will cost a similar amount to fossils fuels such as coal and gas, thanks to falling technology costs, according to new forecasts released in the CO2CRC’s Australian Power Generation Technology (APGT) Report.
The giant Ivanpah solar power plant in the California Mojave Desert recently detailed how much natural gas it burned to generate power when the sun wasn't sufficient — the equivalent to 46,000 tonnes of CO2 emissions in its first year, according to reports.
The practice of pricing fuel with a fraction of a penny is thought to have started around the 1930s. While we can't be sure who was the first to price fuel this way, it seems to have become relatively commonplace across the United States all the sudden around the same time. So what happened? In short- taxes and the Great Depression.
A few months ago, The New York Times sent a photographer to South Korea to photograph the world's largest floating object. It took him hundreds of shots to capture the behemoth. Now, its makers are giving us a closer look at building of the ship.
When the residents of Tulsa, Oklahoma buried a car in 1957 as part of an enormous time capsule, they included containers of gasoline. The good people of Tusla reasoned that the folks of 2007 might not have any gas left to fill up the Plymouth Belvedere that they were interring for a fifty year journey into the future. Boy were they ever wrong.
Pittsburgh International Airport has seen better days. Saddled with debt from building now unused gates, the troubled airport is expanding into a completely different business: fracking. The airport will stay open as drillers tap the gas reserves underneath, thanks to a technique called horizontal drilling.
If you live in an old city surrounded by history, chances are you also live with hundreds if not thousands of gas leaks all around you. It's bad for you (think explosions) and bad for the environment (think global warming), so we should probably do something about it. That's why Google Street View and the Environmental Defence Fund (EDF) have teamed up to map methane leaks in cities.
