You work with the development of new technologies in renewable energy

You work with the development of new technologies in renewable energy. The graduate economists who
values the technology projects in the company constantly tells you that the present value in
the projects are negative, and that the projects should therefore not be initiated. They say that
the technologies are too uncertain and the costs seem to be too high.

Do you have any arguments that can contribute to some of the projects being seen in
new light? Explain. What can affect the value?
