I want to know the answer to the following question:
As of 2008, geothermal power development was underway in more than how many countries?
All the background I'm provided with is that "As of 2008[update], geothermal power development was under way in more than 40 countries, partially attributable to the development of new technologies, such as Enhanced Geothermal Systems.". Is that enough to answer the question?
Answer: yes
