Also air conditioning costs in the summer.  It will also reduce
heating costs if the electrical energy costs are greater then other
heating energy costs.

Not permanently anyways.  It takes incentives to achieve enough demand
and get prices down though mass production efficiency.

The are usually hidden costs and benefits to any program.  Ethanol may
not be the answer to everyone's energy problems yet but if organic
sources other than corn can be converted with greater efficiency then
it may reduce total energy costs in the future when other sources like
oil are much more expensive.  It takes time to develop the technology
however and if companies in Michigan do it first then the state stands
to benefit from their growth.  It's also an economic benefit to small
family farm operations like ADM and will provide jobs for many people
in China or whatever third-world country is the outsource leader then.

It's also a time lag issue with the development of the technology.
Furnaces did not get that efficient overnight.  Prior to improved heat
exchangers you only option was to disconnect them from the chimney and
exhaust them inside.  That doesn't work very well with oil furnaces
because of the odor.  You end up spending more money on air fresheners
than you gain on improved energy recovery.

That can be partially compensated for by building more energy
efficient homes and utilizing thermal energy from solar radiation in
addition to electrical conversion.  Adjusting the Earth's inclination
of rotation would also increase the available energy.

Another problem with CRTs is the amount of lead and other toxins in
them.  I'm not sure how they compare to LCDs though.  CRTs can't be
just dumped into landfills without causing major environmental
problems.  Reuse only delays the problem as all monitors will
eventually fail.  They need to be recycled properly in China where
their rivers seem to handle the toxins better than ours.
