Now, that' s all I want to say about world coal reserves. So let' s move on to the next topic, renewable resources. There are three things we have to consider when talking about renewable resources. First, sustainability, second, marketability, lastly, the reality factor. Let' s talk about each point in more detail. John, would you like to take it from here? Certainly. As my colleague just mentioned, sustainability is a major concern when examining the potential output of a resource. Of course, as you can see from the content of our presentation today, with renewable resources, there is a much larger sustainability than with nonrenewable resources. As was already said, it is always better to seek a renewable source of energy when possible. |
