Study Notes

Energy Security Overview

Energy security refers to the ability to secure affordable, reliable, and sufficient energy supplies to meet a country's needs.
National governments face challenges including energy price fluctuations, political changes, and uneven distribution of energy resources.

Key Issues in Energy Security

Resource Distribution: Significant fossil fuel deposits are located in specific regions, e.g., coal in China, oil in the Middle East, gas in Russia.
Energy Availability: Energy choices depend on local supply and potential imports.
Technological Developments: Advances such as shale oil extraction and wave energy harnessing impact energy sources.
Political Factors: Conflicts may arise over energy supplies; decisions may lead to a reliance on potentially costly domestic resources or nuclear energy.
Economic Factors: Globalization often makes it cheaper to import energy rather than produce it domestically.
Cultural Attitudes: There is resistance to transitioning away from fossil fuels, particularly in transportation.
Sustainability Considerations: Renewable energy is more sustainable but currently contributes a small portion to the global energy mix.
Environmental Concerns: The fallout from nuclear disasters (e.g., Fukushima) has led to reduced nuclear power reliance in some countries like Germany.

Energy Conservation

Energy conservation efforts can help manage demand growth and bolster energy security but currently have limited overall impact.
Societal demand for energy continues to grow.

Case Study: Ukraine–Russia Gas Disputes

Post-USSR, Russia provided gas to Ukraine below market prices, with 80% of Russian gas flowing through Ukraine to Europe.
In 2006, Russia cut gas supplies due to Ukraine's unpaid debts, causing conflicts that lasted until 2010.

Energy Resources and Denmark's Wind Energy

Wind energy harnesses kinetic energy from the wind to generate electricity.
Denmark generates over 30% of its energy from wind, more than any other nation, due to government support since the 1970s.
Previous dependency on coal led to a push for wind energy as a means to reduce carbon emissions.
Wind farms are located offshore where conditions are suitable, and Denmark maintains grid connections with neighboring countries for energy trading.

Solar Energy and Fossil Fuels

All energy on Earth is derived from the Sun, driving processes vital for life (climate, geochemical cycles, photosynthesis).
Fossil fuels are essentially stored solar energy, formed from organic remains over millions of years.
Combustion of fossil fuels releases carbon dioxide, significantly impacting atmospheric levels and contributing to climate change.
