Solar energy is coming to the attention of more folks but in terms of its utilization, there is still a long way to go. As with most things, a lot of words can be uttered without anyone actually doing anything in realistic terms. Solar as an energy source can be a factor in the health of our environment. Since the beginning of time, energy from the sun has been employed as a heating source. As a source of energy, solar energy is renewable, is convenient, and is easily available, even more so than water or wind. On a hunting expedition through Africa in the nineteenth century, solar power was used for cooking. Nowadays anyone can benefit from the use of this alternative source of energy. Numerous new applications for solar energy are being developed at all times.
Since the energy crisis, solar has become a common source of energy. People have been setting up solar panels on their roofs as early as the 1970s. Dwellings have been powered in this manner even if it is alongside conventional energy sources. It is becoming more usual for individuals to be running their entire home with their solar panels. These types of homes make use of direct power during the day, and battery stored power at night. Doing this, non-renewable power is never consumed.
For many people, the only reason they have solar energy is to power a hot water heater. The manner by which this works can vary depending on the method employed. Either passive energy, with the sun heating a water tank, or solar collectors with the sun heating fluids to be transferred. With this system, solar panels are installed, with tubes located behind the panels. The sun heats up fluids inside the tubes. These tubes are beside the water tank, and channel heat from the fluids to the water.
One other way is used mainly to heat up the water in swimming pools. The water runs directly through the water tubes being heated by the sun and is subsequently pumped into the swimming pool. This is a good way for a swimming pool owner to save energy by not needing a pool heater. As solar energy becomes more and more mainstream, there will continue to be those who are looking for more advanced ways to tap into this. Solar energy for an RV for people going on a road trip is an example of how this is developing into other areas. There are even small solar panels that can be used for laptops and netbooks, and cell phones.
As energy costs increase, the market will introduce more of this type of product. From an environmental perspective, any change to solar energy will be advantageous. The planet's eco system will be damaged if we continue to rely traditional sources of energy. The safety of later generations depends on us living greener lifestyles now.
