There is no simple and quick answer to this question. However, a good starting point is to begin reading up on LEED building standards.
When it comes to lighting and power in your home you need to look no further than AUTOMATION. Automating the power in your home will give you absolute control of consumption and dramatically reduce your bills. Help save the environment with LED lights.
The initial outlay on these fixtures will be repaid handsomely in reduced consumption and minimum lamp replacement.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
