Energy Mix and Geothermal Power in Iceland

These flashcards cover key concepts regarding the energy mix, geothermal power, and hydroelectric power in Iceland, focusing on definitions, advantages, disadvantages, and specific locations.

Energy Mix

The combination of different energy sources used to meet a region's or country's energy needs.

Geothermal Energy

Energy derived from the Earth's internal heat, used for electricity production and heating.

Hydroelectric Power

Electricity produced from the energy of flowing water, typically using a dam.

Iceland's Energy Mix

99% of Iceland’s energy needs come from renewable energy, primarily geothermal and hydroelectric sources.

Advantages of Geothermal Power

Clean energy with no pollution or greenhouse gas emissions, and low ongoing operational costs after initial investment.

Disadvantages of Geothermal Power

Limited suitable locations, possible depletion of heat sources, and the risk of hazardous gas emissions.

Advantages of Hydroelectric Power

Consistent electricity production once a dam is built, clean fuel source, and relatively low cost of operation.

Disadvantages of Hydroelectric Power

High construction costs for dams, potential displacement of communities, and impact on fish populations.

Constructive Plate Margin

A tectonic plate boundary where two plates are moving away from each other, allowing magma to rise and create geothermal energy.

Hellisheidi Power Station

The largest geothermal power station in the world, located in Iceland.
