Living off the grid is a challenging effort, but the success of the lifestyle is worth the effort. Living off the grid essentially means using nothing more but renewable energy sources, like wind or sun for power supply. Maybe to have the entire home power supplied with a renewable energy might be a little difficult […]

While it’s easy to produce your own electrical energy, it’s much more difficult to provide your house with enough energy to heat and cool it. Wikipedia says, that typical US […]

Passive solar energy use
Passive solar technology is simply a set of techniques for using sunlight for useful energy without the use of any active mechanical systems. These methods convert sunlight into usable heat (passive solar heating — hot water, warm air, and heat stored in thermal mass), cause air-movement for ventilation, and store heat for future use. Passive […]

History of Solar Energy Usage
We often think that modern societies were the first to use solar energy. Not true! Early cave dwellers preferred caves that had openings facing southeasterly that allowed the morning sun to warm them up without overheating in the warm months. Native Americans in the Southwest oriented their pueblo dwellings. So the low winter sun would […]
