The introduction of steam power fuelled primary by coal, wider utilization wheels and powered machinery (mainly in textile manufacturing) underpinned the dramatic increases in production capacity. The development of all-metal machine tools in the first two decades of the 19th century facilitated the manufacture of more production machines for manufacturing in other industries. The effects spread thoughout Western Europe and North America during the 19th century, eventually affecting most of the world, a process that continues as industrialization. The impact of this change on society was enormous.
