Comparison of employment potential of the coal and wind power industries
Australia, one of the world's largest producers of coal, is used as a case study to compare the employment potential in the coal and wind power electricity generation industries. It is revealed that, as a result of automation, employment in the coal mining industry fell by 45% between 1987 and 2002. Moreover, as a result of the restructuring of the electricity industry as a whole, employment in ...

Why European policymakers shouldn’t be concerned about security of gas supply
Gastech News: What are the key issues affecting gas companies today? Mark Simons: The biggest issue affecting gas companies within the European gas industry is low prices, because low prices mean less revenue and less profit. To add to that, in Europe, the competition for gas from coal and renewables means that demand is down and that’s shrinking the industry which of course is worrying ...

CSP industry gears up ‘to take advantage’ of new opportunities
The recent announcement of the Environmental Protection Agency’s proposed new carbon emission standard for future coal-fired power stations has given the CSP industry yet another huge boost in the fight for an established place in the US energy market, through the use of hybrid CSP plants. This is just one example of the new opportunities this innovative industry is able to take advantage ...

How green energy will change Africa
In 1977, the average price of generating energy from sunshine was $76.67 a watt. Today, the price has dropped to just $0.60 a watt. It’s a stunning 99.2% drop in 38 years, and solar energy is soon going to reach “grid parity” all over the world – the point where it is cheaper, or at least equivalent in price to grid electricity from conventional sources. Last ...

Coal and its future are fueling conflicts around the globe
"Coal Wars: The Future of Energy and the Fate of the Planet" (Palgrave Macmillan), by Richard Martin Fierce conflicts over coal are taking place around the globe, but author Richard Martin says the decline and ultimate demise of the fuel that powered the Industrial Revolution is inevitable and cannot be reversed. What he cannot predict, he says, is whether the transition to energy sources that ...

What is the future of King Coal in China?
When it comes to coal consumption, no other nation comes close to China. The country reigns as the world’s largest coal user, burning almost half of the global total each year. About 70 percent of China’s total energy consumption and nearly 80 percent of its electricity production come from coal, and its recent shift from being a historical net coal exporter to the world’s ...

Occupational safety and health in the wind energy sector
As the European Union power sector continues its move away from oil, coal and nuclear fuels,wind energy has experienced tremendous growth over the past decade and this is expected to continue. The wind energy sector is relatively young with turbine technology constantly progressing and this creates an ongoing responsibility to ensure workers that conduct tasks such as installations, operation, or ...

Carbon capture is a mirage for poor nations
The world is witnessing a coal renaissance. While public attention remains focused on the progress of the clean energy sector, a ‘black revolution’ of coal power stations is taking shape in the developing world, in particular in Asia, according to Ottmar Edenhofer, the chief economist at the Potsdam Institute for Climate Impact Research in Germany. At the Our Common Future under ...

The role of coal technologies to support responsible economic growth
The Asian Pacific region is home to the fastest-growing economies in the world. These economies are expected to double gross domestic product (GDP) in the next decade, and coal will play a major role as the primary energy source for electric power. The tremendous projected financial burden associated with the installation of new, coal-fired electric power facilities to fuel this unprecedented ...
