Humanity uses energy sources which are either extremely harmful for the environment or they are too scarce.Scarcity means that the prices are on a constant increase, and pollution not only affects mother nature but humans as well because they potentially could get a number of diseases.Now did you know that the Sun's energy which reaches the earth is 35.000 times more than what humanity actually needs.Would not it be great if you could harness only a fraction of that free source of energy? I am not saying that it is time to go off the grid just now.Reading on you will learn some cool projects in what you can invest concerning solar power.* Eliminating attic heat During summer there is a large amount of heat gathered in the attic, most of the times these temperatures reach well over 150F.This heat is gathered all through out the day and during the night it leaks in to your home.The good news is that most houses have passive venting is built in but these are highly inefficient.So the idea is that you strategically place fans all through out the attic and power them up with solar power.The end result will be a much cooler house without any extra expense on the electrical bill.All you need is a PV panel a minimal amount of tools and a day at your disposal and all will be done.* Illuminate your back yard This is also a fun solar project to invest in and there are so many variations to try out.First of all we all know how hard and costly is to wire the whole yard and it is a real nightmare if something is out of place and you have to redo everything.These special lights charge up during the day and they light your yard all night long.You do not have to purchase any wires and you can move them from one place to another.Also there is the option of choosing lights which change colors this can add a little mystique to your yard.And you do not need to put it in to direct sunlight, these lights will perform just as well if they are in the shade of a tree.These were just a few great investment ideas if you are looking for to utilize the Sun's power.These are not free projects, you need a small initial investment then you will gain back the money pretty soon.
