Energy Consumption Evolution: 1900-2050

Description: This graph shows the evolution of energy consumption from 1900 to 2050. It illustrates the use of the following energy sources:

• Renewable: Solar, geothermal, wind, hydroelectric
• Non-Renewable: Nuclear, natural gas, crude oil, coal

Source: Deutsche Shell

Analysis

• 1900: Coal (due to industry) and biomass (wood) were the primary energy sources.
• 1950: Coal, natural gas, and oil (non-renewable) began to grow. Nowadays, their use accounts for 75% to 80% of total energy consumption.
• 1970: Alternative energies (renewable) started being used due to the oil crisis of 1973. Forecasts until 2050 predict that alternative energies will grow in importance, and non-renewable sources will decrease.

Solutions to Prevent

Economic Activity

Economic activity is what humans undertake to acquire goods (products and services) that satisfy consumer needs.

Economic Goods

Economic goods are products and services generated by economic activity.

Products

Products are goods obtained directly from nature (e.g., fish) or transformed into something else (e.g., clothes, books). They can be classified by:

• Composition: They can be consumable (durable consumer goods, such as computers, or non-durable, such as pizza) or capital goods (tools).
• Function: They can be intermediate goods (wool produced by a sheep) or finished goods (the shirt made from this wool).
• Ownership: They can be private (belonging to people) or public (belonging to the state).

Factors of Production

Authoritarian Monarchies

During the Modern Age, the feudal European monarchies became authoritarian monarchies. The king reinforced his power over the kingdom as a whole by imposing his authority over the nobility and limiting the autonomy of the municipalities. This new way of organizing the state is referred to as the Modern State.

In Europe, authoritarian monarchy took root in France, England and the kingdoms of the Iberian Peninsula. However, Germany and Italy did not manage to create unified states.

Authoritarian monarchies became especially established in England, where the monarchies of the Tudor dynasty, such as Henry VII, dominated the nobility; in France, where the Valois rulers, such as Louis XI, put an end to the influence of the Dukes...

Natural Cycles

In nature, chemical elements vital to life, such as oxygen, carbon, and nitrogen, are neither made nor destroyed. They are recycled, moving round and round in the natural world in the form of minerals and nutrients. On land, they move from the soil into the plants, then into animals that eat plants, and then sometimes into other animals that eat plant-eating animals. Minerals and nutrients return to the soil either through an animal’s droppings, or whenever any plant or animal dies and rots away. Microorganisms in the soil, such as bacteria, play an important part in releasing the nutrients and minerals from the decaying matter.

The Early Modern Age (1453-1789)

Economy

Societies began to experience:

• Increased Agricultural Production: The three-field system was maintained.
• Intensified Commercial Activity: Increased agricultural production resulted in a surplus (excess food production). Products were sold in city markets, and new trade routes appeared.
• Expansion of Craftsmanship: The domestic system was created.
• New Products were brought to Europe.

• Development of Mercantile Capitalism: An economic system in which capital belonged to private owners. Economic growth led to the development of banking.
• Providing Loans: Bankers lent money in exchange for the return of the same amount plus interest.
• New Forms of Payment: The bill of exchange was created (a document that guaranteed

Age of Industrialisation Proto Industrialisation

The period of industrialization before the first factories came up in Europe is termed as proto-industrialization. This period was marked by merchants from towns getting products made in villages.

Reasons for focus of merchants on villages:

• Powerful trade and craft guilds in urban areas
• Controlled competition and prices
• Prevented entry of new players in the market

Features of proto-industrialization in Britain:

• Merchants supplied money to the peasants in the countryside
• Peasants motivated to produce products for an international market
• Land becoming scarce in villages
• Peasants looking for additional sources of income

The Coming Up Of Factory

The earliest factories in England came up in the 1730s. By late... Continue reading "Proto-Industrialization and the Rise of Factories in Britain and India" »

In the feudal system, the king, the nobles, the clerics, and peasants all had different responsibilities and rights. Basically, the system consists of:

• Somebody gave protection/land to someone else.
• In exchange, the other had to fight or work for their protection.

The King

The king was the ruler of the country and owned all the land. However, he didn't have a big army and was weak. This is why he needed the noblemen and their armies.

The Noblemen

The noblemen were the vassals of the king. They promised obedience and loyalty to the king in the ceremony of homage. They provided knights and in return received a land (fief). In their lands, as lords, they acted as judges and collected taxes for themselves.

Knights

Knights were less important nobles, were... Continue reading "Feudal System: Roles and Responsibilities of King, Nobles, and Peasants" »

The Kyoto Protocol: Reducing Greenhouse Gases

The Kyoto Protocol (KP) is a UN international treaty committing State Parties to reduce greenhouse gas (GHG) emissions (primarily CO2) to combat global warming. It was adopted in Kyoto, Japan, in 1997.

Specific Goals and Challenges

• Initial Goal (2005–2012): To reduce the collective emission of greenhouse gases to a limit compared to 1990 levels.
• Extension (2012): The KP was technically extended until 2020, but its impact was limited to only 15% of global CO2 emissions.

Reasons for Limited Participation

This limitation was due to the lack of participation from many industrialized and emerging countries, including:

• USA
• Canada
• Japan
• Russia
• Belarus
• Ukraine
• New Zealand
• China
• India
• Brazil
