FIGURE 1.1 A large coal-fired steam-electric power plant whose electrical power output is nearly 3,000 megawatts. In the center are the
power house and tall stacks that disperse the flue gas. To the left, a cooling tower provides cool water for condensing the steam from the
turbines. To the right, high-voltage transmission lines send the electric power to consumers. (Copyright Brian Hayes.)

FIGURE 1.2 A run-of-the-river hydropower plant on the Androscoggin River in Brunswick, Maine (United States). In the center is the
power house, on the right is the dam/spillway, and on the left is a fish ladder to allow anadromous species to move upriver around
the dam. Except when occasional springtime excessive flows are diverted to the spillway, the entire river flow passes through the
power house.
