Global Energy Consumption: Trends and Alternatives
UNIT 3 INTRODUCTION
Energy consumption is thirty times higher than a century ago. This growth necessitates developing new techniques to enhance the exploitation of existing sources and gradually replace non-renewable ones showing signs of depletion. The goal of developed countries should be the effective and rational use of energy to secure future resources.
HISTORY OF POWER CONSUMPTION
In studying evolution, two variables must be considered: primary energy consumption and transformed (secondary) energy

Preindustrial Stage
Physical inactivity is a characteristic of the most recent human populations where groups cease to be nomadic and settle permanently. This transition from nomadic to sedentary lifestyles began with the Neolithic agricultural revolution about 10,000 years ago, spreading across all continents:
- Improved equipment, tools, and storage systems
- Division of labor (skilled trades first)
- Emergence of property rights
- Early writing systems
- Organized religions and states
- War and slavery

Demographic and Industrial Shifts
What factors were instrumental in changing demographics? What were the consequences for population evolution?
The factors are: population growth, increasing food production, and advances in hygiene and medicine. As a consequence, there was a decrease in mortality and increased fertility.
The Rise of the Factory System
What is the factory system of production? What factors led to it?
The factory system is the concentration of workers and machines in large industrial buildings.

The rural area is primarily undeveloped land, historically dedicated to agriculture, livestock farming, and forestry.
Physical and Human Factors
Environment
Relief
High altitudes and steep slopes can both facilitate and impede erosion and machining.
Climate
Characterized by low and erratic rainfall, frequent storms and hail, extreme temperatures (frost or intense sunlight), and varying degrees of aridity.
Soils
Poor quality soils often suffer from erosion, reducing fertility.
Agrarian Structure
Traditional

The Traditional Industry and Manufacturing. Everything needed for daily consumption was often produced within the family. The peasant family was the basic production unit, working the land to produce goods for domestic consumption. In cities, medieval artisan production was controlled by guilds: groups of artisans in the same profession who controlled production volume, techniques, and sales prices. The increasing demand for products encouraged traders and craftsmen to seek new production systems
Understanding Urban Development: Key Concepts and Challenges
Criteria for Defining a City
Number of Inhabitants
While population size is a key factor, there’s no universal minimum. In Spain, a population of 10,000 is considered urban.
Habitat Concentration, Density, and Continuity
Cities often exhibit high population density, but even low-density residential areas can be considered urban.
Economic Activity
Cities are characterized by diverse economic activities, unlike rural centers focused on the primary sector.
Territorial Influence
Cities concentrate administrative,
