In deciding on proposals to introduce new technologies or to curtail
existing ones, some key questions arise concerning alternatives, risks,
costs, and benefits. What alternative ways are there to achieve the same
ends, and how do the alternatives compare to the plan being put forward?
Who benefits and who suffers? What are the financial and social costs,
do they change over time, and who bears them? What are the risks associated
with using (or not using) the new technology, how serious are they, and
who is in jeopardy? What human, material, and energy resources will be
needed to build, install, operate, maintain, and replace the new technology,
and where will they come from? How will the new technology and its waste
products be disposed of and at what costs?
