the climate of the Earth went into a series of climatic optimum when vast coal deposits formed. This project will investigate evidence of these events by studying the carbon isotopes within a series of exceptionally thick coals in the onshore Gippsland Basin southeast Australia. The detailed[...
Not surprisingly, wind speed or “wind resource” is the primary determiner of how much electricity a turbine can generate. Wind resourcesare abundant in Australia, particularly in the South and Victoria. Wind speed is highly variable and forecasts of how much electricity you can expect to generat...
aChina is a big industrial country so there are a great number of factories. Much dirty air is released everyday. There is so much traffic in China that burning of oil and coal, and the exhaust from cars and trucks cause serious air pollution. The air that was polluted can hardly breath...

"For the most part, the mining industry has got too much invested in these operations to screw up," said Deery " ... If they get put out of business, nobody's ever going to hire them again." Prospectors and novices alike: Check out the resources below for more on uranium mining. ...
A key contributor to the decline in emissions is cleaner energy production. Throughout the 2000s, natural gas gradually replaced coal as the primary energy source. Other energy sources such as nuclear, wind, and solar have further reduced dependence on fossil fuels. Policy Shifts In the U.S...
Looking around the colossal mine, evidence of an ancient wilderness can be seen everywhere. Every time another feet-thick vein of coal is trucked away, an underlayer of mudstone is left behind, rich in the fossils of exotic leaves and plants and in the bones of fabulous creatures. ...
Magnetite is a tiny part of our iron ore exports � but that could change. Australia has vast reserves of magnetite ore, which previously hasn�t been in as much demand. But these ore bodies will become valuable under the right economic conditions. ...
Australia is a major exporter of commodities such as iron ore, coal, and natural gas, so theAUDis highly sensitive to shifts in commodity prices, inflation, and global demand. When inflation rises or falls, the exchange rate tends to adjust accordingly. Like other central banks, the RBA ...
