Generally its a cost related issue, or a lack of knowledge of the benefit of solar power. It has a large initial cost, but generally the payback is between 7 to 10 years depending on where you live, rebates and type of electric pay rates.
It can also be a matter of convenience, and space. Many people just don't want to have to bother with one, and some people just might not have anywhere to put one.

Many areas have no payback period. In some areas we get as little as 150 watts per day from 75 watt panels. This means payback on these panels is well past their expected lifespan. The panel set installed on my home has a projected payback of over fifty years.
This doesn't mean that they are bad in all applications. Care must be made when deciding of the concept works for you. Areas to avoid include warm areas as heat degrades solar panel operation and lifespan by large amounts. Far Northern or Southern areas that receive less sunlight are also a bad idea.
Some local utilities are also not required (as of this date) to perform net metering (most large utilities must). This would then require large and expensive banks of batteries. Mine complete system (self installed) was over $10K and provides over $3.00 a month in total energy. It is a wonderful backup system, but does require a fair amount of maintenance,
through the electricity company. XD
Ground wires
Electricity is produced in power station and then passed through to a generator. The generator passes the electricity through lines and then to another generator. it is again passed through lines and then to a primary customer which may be an industry or an electricity company. It is then passed on to a secondary customer through power lines through to your house.
They are not. They're run by current electricity, that comes from the power company and through the meter outside your house.
You can do this through a number of ways. You can choose to go and ask the store where you bought your GPS system if they provide the installing CD, look for it in the internet, or call the company of your GPS system.
Electricity boards are expensive, short-term power. An individual usually cannot purchase it at home stores, but he or she has to order it through a electrical company.
The wirering will not change. Your phone is simply routed through their company instead. Usually the package deal like that still goes through a phone company signed on with the cable company.
The Eastern Electricity Board was formed in 1948 after the Electricity Act of 1947 was passed. In 1990 it became the Eastern Electricity plc following the Electricity Act of 1989. The company then passed through the Hanson plc, followed by TXU Europe, and was finally sold on to EDF Energy.
Grounding is important, because it protects users of electricity from potentially fatal electrical shocks. This is accomplished through bolting, clamping or other effective mechanical means to provide an effective grounding path to the earth instead of through the user.
An electron is electricity as we know it. Electrons flow through a conductable element and that is electricity.
Yes, electricity can flow through metal.
Seems to be a joke question...Of course properly and well dimensioned insulatedwires
