Solar power works well for most items except large electric appliances that use an electric heat element such as a water heater, clothes dryer and electric stove. Ex: Total electric home heating systems. It is not cost effective to use solar power for these items. Conversion to natural gas, propane or other alternative is usually recommended.

The efficiency of solar arrays depends in part on the area where you live, sunny areas while benefit more from this alternative energy than areas from colder climates and less sun exposure. Nevertheless, this could set an example for other people to switch to alternative energy.

Technology today already has the ability to completely replace oil, but it would be a long process as it would not be in the benefit of large corporations.
