Experiment 1: The Effects of Coal Mining Coal mining‚ particularly surface mining‚ leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite‚ a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab‚ you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated. Materials: (3) 100 mL Beakers 1 tsp. Crushed pyrite 1 tsp. Activated

providing just 1.4% of total output. * Although coal-fired power stations still provide 34% of total electricity‚ the domestic coal industry is a shadow of its former self. Coal-fired power stations are less polluting than they once were‚ but still produce large amounts of greenhouse gases. However‚ some believe the emerging technology of "carbon capture"‚ in which emissions are not released into the atmosphere‚ could see a new lease of life for coal. * Power from running water currently supplies

Electricity in Ireland In the 19th century‚ the electrical revolution‚ which was sweeping the rest of the developed world‚ looked set to bypass Ireland. Only a few selected locations around the country had this incredible new power source ’on tap’. However‚ thanks to the determination of a handful of far-sighted people‚ electricity was soon to take its first tentative steps towards becoming the ubiquitous and indispensable power source it has proved to be.
