Câu nào đúng khi nói về việc sản xuất năng lượng địa nhiệt trên thế giới?

A. Bởi vì nó là ý tưởng mới, nên rất ít quốc gia có nguồn năng lượng địa nhiệt

B. Chỉ một số nước ở Nam Bán Cầu sử dụng năng lượng địa nhiệt quy mô lớn.

C. Cho đến khi giá của năng lượng địa nhiệt trở nên cạnh tranh , nó sẽ không được sử dụng trên toàn cầu.

D. Năng lượng địa nhiệt đã được sử dụng ở một số quốc gia , nhưng nó vẫn chưa phải là nguồn năng lượng chính.

Dẫn chứng: Today, Earth‟s natural internal heat is being used to generate electricity in 21 countries , including Russia, Japan, New Zealand, Iceland, Mexico, Ethiopia, Guatemala, EI Salvador, the Philippines, and the United States .Total worldwide production is approaching 9,000 MW (equivalent to nine large modern coal-burning or nuclear power plants)-double the amount in 1980 .Some 40 million people today receive their electricity from geothermal energy at a cost competitive with that of other energy sources. In EI Salvador , geothermal energy is supplying 30% of the total electric energy used. However, at the global level, geothermal energy supplies less than 0,15%of the total energy supply.
