During the earliest period of industrialization in Britain, steam engines were more expensive to build and operate than either windmills or water mills, the other practicable sources of power for factories. Yet despite their significant cost disadvantage, steam-powered factories were built in large numbers well before technical improvements brought their cost down. Furthermore, they were built even in regions where geographical conditions permitted the construction of wind- and waterpowered factories close to major markets.
Which of the following, if true, most helps to explain the proliferation of steam-powered factories during the earliest period of industrialization in Britain?
