Cities may be improved with a wide variety of buildings, each with a different effect. Each city may have only one of each improvement, and some improvements require others to have been built first.
It costs production points to build improvements, and once completed, many improvements require an upkeep of one or more gold pieces per turn. You may dismantle and sell an improvement, receiving one gold piece for each production point used in its construction, although you may only sell one improvement per city per turn. If a turn comes on which you cannot pay the upkeep on all of your improvements, some of them will be automatically sold; obviously this should be avoided as the improvements chosen might not be ones you would have preferred to sell.
Most improvements become available only when you achieve certain technologies, and some improvements can become obsolete, at which point they are automatically sold.

The Granary decreases food waste in the city as it grows. When any small city grows or shrinks, 10 food points are saved instead of wasted. This helps cities to grow faster and more easily withstand famine. With a Granary this benefit is extended to cities of size 4 and above. Ten food points is half of what a small city needs to grow, but more points are needed for later growth steps.
A Granary also halves the food wasted in cities far from your capital. Together with a Windmill/Watermill/Supermarket it eliminates food waste, except of Despotism where Courthouse is also required.
TIP1: To maximize the speed with which a city grows, you should build a Granary before it grows larger than size 4.
TIP2: Granary is mandatory for Rapture growth under First Republic, Direct Democracy or Legalism governments.

Any kind of electrical plant increases the shield production effect of any Factory or Mfg. Plant in its city by 25% each. Thus, an electrical plant in combination with either a Factory or a Mfg. Plant gives a 50% production bonus over the level without any of these improvements. An electrical plant, Factory, and Mfg. Plant together give a 100% production bonus. The extra production will lead to the city generating more pollution.
However, a Hydro Plant also reduces the pollution associated with shield production to 50% of its normal value, or 25% in combination with a Recycling Center. Pollution is reduced further for the player who owns the Hoover Dam (small wonder).

Any kind of electrical plant increases the shield production effect of any Factory or Mfg. Plant in its city by 25% each. Thus, an electrical plant in combination with either a Factory or a Mfg. Plant gives a 50% production bonus over the level without any of these improvements. An electrical plant, Factory, and Mfg. Plant together give a 100% production bonus. The extra production will lead to the city generating more pollution.
A Solar Plant also reduces the pollution associated with shield production to 25% of its normal value, or eliminates it entirely in combination with a Recycling Center.
