Hydropower is more commonly known as hydraulic or water power. While this type of alternate energy has been used for hundreds of years, it is still not being utilized as much as it should be and is now finally growing more and more popular in recent years past. The largest use for water energy today is the creation of hydroelectricity, which allows for this low cost energy to be used from great distances to the water energy source. While this type of use is helping to define hydropower in today’s day and age, one must take a look back at the types of uses we have developed from to understand just how important hydropower is and always has been to our earth and civilizations.
You might be wondering what exactly is hydro power used for, and why do we use it? Well, even in Imperial Rome they realized the tremendous value of this energy and utilized it through the use of powered mills to produce flour and grain, and also cut timber and stone. The Romans were and are not the only ones that see the power of water energy as great and useful.
Water mills and windmills have been used as far back as the middle ages in Europe. India for example has been using wind and water mills now for over 200 years. This time frame was a burst of ideas regarding hydro power, and many countries began to take advantage. China and most of Asia were using hydraulically powered “pot wheel” pumps to raise water into irrigation canals, and they were not the only one thinking like this. The 1830′s was the peak of the canal building era and hydropower was being used greatly. The main use commercially was controlling barge traffic, and helping these vehicles up steep hills with the help of inclined plain railroads.
As time went on, the uses for hydropower and the understanding of how to make this form of energy as efficient as possible became the focus for many countries and people involved. During the 2nd half of the 19th century many people started to understand that some direct mechanical transmission was required, and that companies wanting to uses this type of energy had to locate themselves near a waterfall. This concept exploded in and around Minneapolis, originally at the Saint Anthony Falls along the Mississippi river, and literally helped create the grand city we know today.
