Global Energy Production and the Secondary Economic Sector

The Secondary Economic Sector

The secondary sector encompasses economic activities involving the processing of raw materials. This transformation occurs through manual labor or by the use of machinery to create finished goods for human consumption.

While mining could be included in the primary sector, it is typically classified under the secondary sector because the fate of minerals is not direct human consumption but rather their transformation within industry.

Global Energy Sources and Consumption

Energy sources are crucial for the secondary sector. These include non-renewable sources whose reserves are gradually depleted (such as oil, natural gas, coal, and radioactive minerals like uranium and plutonium) and renewable sources. Generally, the most industrialized countries are those that consume the most energy.

Non-Renewable Energy Sources

Oil

• Oil accounts for approximately 40% of the energy consumed worldwide.
• The energy dependence of wealthy countries, including the U.S., led to efforts to control oil deposits, refining, and marketing. This control was historically exercised by large companies, mostly American, known collectively as the Seven Sisters.
• Facing the power of these companies, many producing countries formed OPEC (Organization of the Petroleum Exporting Countries) in 1960 to reclaim control of prices and production quotas.
• In 1973, OPEC raised oil prices, initiating the Oil Crisis.
• Since most oil reserves are located in the Middle East, this area has been central to critical moments in international relations ever since.

Natural Gas

Natural gas has recently become the second most used source of energy globally due to several factors:

• Huge available stocks.
• Easy transportation by pipeline.
• Lower polluting effects compared to other fossil fuels.

Coal

Although coal is the most polluting fossil fuel, abundant reserves exist, and it contributes approximately 25% of global energy consumption.

Nuclear Power

Nuclear power was presented as a viable alternative, but it faces significant challenges:

• Nuclear power plants require large amounts of capital for installation and operation.
• Operational lifespan should not extend beyond 30 years.
• The persistent problem of dangerous radioactive waste.

Renewable and Alternative Energy Sources

Renewable sources, such as hydropower and alternative energies (solar, wind, tidal, geothermal, and biomass), could be the long-term solution. These sources are inexhaustible and clean, but they currently represent only 3% of total energy production.

More research is needed to achieve large-scale energy production through these methods.
