Nuclear Power seems a very viable option to replace fossil fuels. But
I think that Nuclear power poses a very real threat to our existence.
What if the nuclear power plant falls into the hands of terrorists?
Also how to dispose off the nuclear waste and what about proliferation
secure and safe?Wind energy can not be used in the non-windy areas.
The only other option seems to be solar which is abundant in almost
every part of the world. If we can produce some really cheap solar
cells that would solve the problem. Today solar power represents a
small fraction of energy production in USA. Just imagine that
installing solar panels and not having to pay energy bills . I am
myself thinking about going the solar energy way.I visited a website
<a href="http://FreeCleanSolar.com">  FreeCleanSolar.com </a> to get
some information. This is a pretty good site to get started. Comments
are invited

    This is off topic but ....


    Look up pebble bed reactors and other thorium based reactor designs.


    Nuclear reactors have to be designed with weapons grade
fissionables in mind for this to be a problem. They don't have to be
designed that way but in the 50s and 60s weapons were *wanted*. Recently
interest in the many designs that produce power without producing dangerous
waste or use/produce weapons grade materials has returned.


    True - but energy distribution is a well established technology.


    But only during the day and then only when not cloudy - which makes
solar only suitable when energy storage is feasible (thermal storage can be
efficient and cheap so solar thermal can be effective - to drag this
somewhere near topic) or when alternatives are available for use when the
sun doesn't shine - which makes solar electric potentially feasible for grid
scale use.


    No! Really cheap, long life, low maintenance, high capacity storage
batteries would go a long way to making local scale solar electric feasible
but the photovoltaic cells themselves are not the major cost of a system.

 Why don't we, the Human Race, Reduce out greedy need, and stop wasting!

    Because while an individual human being may appear intelligent and
occasionally act rationally the more of them you put together the less
signs there are of intelligence and rationality.

 Because we didn't know we needed to.

Why don't we, the Human Race, Reduce out greedy need, and stop wasting!
