CLEAN : Iceland drills 4.7 km down into volcano to tap clean energy

The video discusses the benefits and limitations of geothermal energy in Iceland, highlighting its affordability and partial renewability. It critiques Iceland's economic focus on heavy industries and tourism, noting a lack of sustainability planning. The potential of supercritical wells to significantly increase energy output is explored, suggesting a shift from conventional wells could reduce the number needed for energy generation.

What is one of the main advantages of Iceland's geothermal energy?

• It is the only energy source used in Iceland.

• It has no environmental impact.

• It is more affordable and accessible than other energy sources.

• It is completely renewable.

What is a major concern about Iceland's current government plans?

• They are not addressing the rapid growth in tourism.

• They are investing too much in coal and gas.

• They are reducing heavy industries.

• They are focusing too much on renewable energy.

How does the speaker view Iceland's position on sustainability?

• Iceland is behind in sustainability thinking.

• Iceland is leading in sustainability efforts.

• Iceland has no sustainability issues.

• Iceland is on par with other countries in sustainability.

What is the expected power output from a supercritical well compared to a conventional well?

• 50 megawatts or more

• 10 megawatts

• 100 megawatts

• 5 megawatts

How many supercritical wells would be needed to match the output of 30-35 conventional wells?

• 10-15

• 20-25

• 3-5

• 5-10
