the coal industry may reverse its decline in 2014. Coal stockpiles have disappeared at a faster clip than at any time in the past decade due to cold weather and higher natural gas prices. The East Coast is dealing with record cold temperatures, and with consumers using more energy to stay warm, natural gas prices have rapidly increased. This has many utilities turning back to coal. After burning through stockpiles, utilities will be forced to purchase more coal from producers in Wyoming. among the country's 10 biggest coal mines as measured by 2013 production employment has dropped by just 0.5%; exactly half of them increased employment numbers between 2011 and 2013.Only one of these mines was not a top-10 producer in 2011 and all of them are located in the north-western US where coal is generally cheaper to extract and has lower sulphur content. Mining regulators and managers have been slow to deploy mobile technologies, which is not surprising given the hazardous conditions they work in. But it is because it is so hazardous that they have so much to gain. Where they have been introduced, we have seen a safer and more productive workforce – and this is starting to win people over,” says Riva Richmond, the editor of the report. Now, starting in 2011, this new generation of clean diesel technology for off-road engines and equipment known as Tier 4 will be making its way onto the construction and industrial jobsites and farm fields around the country. The equipment used in farming, mining and construction is uniquely qualified to do demanding work. No other power source shares diesel's reliability, durability and fuel-efficiency for these off-road applications.
