Merchants built factories that needed water power that had to be built near water. People learned they could burn coal to make hot water for steam power. In 1769, James Watt built a good steam engine. The steam engines were being used to run machines in factories instead of water power. Now factories could be built farther away from water sources.

Mining the Coal Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many coal beds are very near the ground's surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves.

Huge machines called draglines—some the size of an entire city block, able to scoop up to 100 tons in a single load—push rock and dirt into nearby streams and valleys, forever burying waterways. Coal companies use explosives to blast as much as 800 to 1,000 feet off the tops of mountains in order to reach thin coal seams buried deep below.
