When it comes to energy policy, Estonia is a quite rare country in Europe and in the whole world. Estonia does not have high valued energy sources like oil, gas or even coal, but does have oil shale. This natural resource is mostly not even used because recourses with higher value are preferred. But since Estonia does not have anything else, the oil shale industry has been developed from 1940. But beside oil shale, other indicators are important to describe when describing the Estonian energy policy.
