The map shows the average potential solar power in kWhr per sq meter flat collector surface (about 10 sq feet) per day in different parts of USA. Use this as a guide only to show relative availability of solar power conversion potential. Blue is lowest and red highest in terms of hours per day average.
Solar Power Benefits & Trends and Why Solar Powered Applications Are so important to the world
The use and application of solar power has been expanding at over 35% for more than 5 years (ref DOE). The size of the solar energy industry is measured in watts and it was estimated that world production of solar power would exceed 1 billion watts in 2004 which is ten times more than only 8 years earlier.
California state alone is estimated to be the 3rd largest consumer of solar powered applications in the world.
1.5 million US homes have installed solar powered water heating systems and in 2003 alone more than 35,000 solar heated swimming pool systems were installed.
The use of solar power has widespread public support because it is easy to see and feel the benefits. Arnold Schwarzenegger as Governor of California in a speech on February 28th 2005 said
Gov. Schwarzenegger Promises 1,000,000 solar roofs
"I promised the people of California during the campaign that as governor I would push for solar power. Today, I am keeping that promise to harness renewable solar energy with the help of my friends Senator Murray and Senator Campbell, to create one million solar roofs." - Gov. Schwarzenegger, February 28th, 2005

Advantages of solar power and Solar Powered Applications
Easy to install and easy to site ... solar power can be used almost anywhere. Homes, offices, factories, malls, crowded areas, sparse populated areas
Solar power and energy creates something like 5 times a many jobs as the equivalent conventional energy systems per unit of energy generated.
The price or running cost is virtually constant with the cost being for a capital installation. This is unlike conventional oil, coal or gas energy which will inevitably rise as these natural resources get consumed and become more scarce.
There is no greenhouse gas effect or air pollution created by solar powered installations. In these days of confirmed climate change this is critical. It has been estimated that a single solar powered home heating system saves the polluting equivalent of driving a car for about 4,000 miles.
In addition to saving the atmosphere from polluting gases solar powered applications have the effect of reducing by as much as 98% the water required (and blown away as steam) of a conventionally generated MWh of electricity
Consider other types of water heating and costs of heating water for the home
