If you get your energy through places like http://www.EnergySavings.com, then there is an exceptionally good possibility that you have heard about solar energy. Solar energy, in layman’s terms, is energy derived through the harnessing of the sun’s natural energy, but did you also know that there are two very different kinds and two very different ways of harnessing them? It’s true and we’re going to talk about both of them, right now.
We’ll start with passive solar energy. This form of solar energy basically relies on the sun to be shining. Special materials built into a home make use of this energy with greenhouse glass, which focuses the light into heat, and specially built walls that capture heat and disperse it about the home. These materials are usually built into the south side of any home to make the most of the sunlight.
Active solar energy relies on all those fancy solar arrays and cells you see on top of houses and even on the International Space Station. These implements actually capture solar radiation which can then be channeled into immediate energy applications like heating water or cooking or lighting a room.
Both types of solar energy are used each day, but understanding each and how they work is important if any progress is to be made in the field of renewable energy.
