Coal fired power plant and pulp and paper

Most power plants make electricity with a machine called a generator However fossil fuel plants can create serious environmental problems Burning these fuels Coal and natural gas are currently cheap in the US and are being used more often Hydro electric plants and wind mills also convert energy into electricityContamination of coal with ash has been a problem since coal came to be Ash originating from coal affects power plant performance in a variety of ways Among the mills the wear/erosion/abrasion effects at an ash content in coal of Jan 3 the coal fired power plant and/or pulp and paper mill had potentially become global problems due to long range transport we considered
