Alternative energy generally refers to any group of non-traditional fuel sources that does not burn fossil fuels or use up any type of natural resources which will result in damage or harm to the environment. In other words “Alternative Energy” is clean energy, well at least in theory. Alternative energy sources provide many benefits over the use of the more traditional fossil fuels such as less harmful pollution and cheaper fuel prices.

Sources of Fresh and Salt Water
•Water, water, everywhere .... "
•I have heard this phrase, and for water, it is true. The earth's water (almost) is everywhere: above ground in the air and clouds, on the surface of the earth in rivers, oceans, ice, plants, organisms and inland within a few miles of land.
•Global water distribution by the numbers
•The Earth holds about 326 million trillion gallons (326,000,000,000,000,000,000 gallons) of water.
•If you crunch the numbers, here’s the percentage in global water distribution of all these sources of water.
