The next big problem that’s going to hit people is the cost of energy. It is already skyrocketing and burdening our wallets. However, the idea of energy efficient home comes as a rescuer in this regard. It not only has a good effect on the environment but also helps you mend the big hole in [...]
With the depletion of the traditional fuel sources, the alternate fuel sources available nowadays become more and more important. Although there are lots of different fuel sources, gas for example is nearly out, so the more we use any alternate fuel source the better it is both for environment and for our fellow men. Extracting [...]
Temperature, Humidity and Killawatt Hour Usage and tracking are great ways to monitor your overall energy usage. By monitoring heat and AC activity on your computer and learning how energy is used, costs can be reduced.

Many homeowners worry about their home heating bills only when temperatures begin to drop. This can be a costly mistake. Demand for efficient hearth products, such as freestanding stoves or fireplace inserts, skyrockets in cooler months, often exceeding supply. If you were in the market for a hearth product last winter, you may have [...]
In 1932, J.M. Custer of Piggott, Arkansas had an idea for a car that would run on compressed air. He not only built the car, but it actually ran. He used an engine that resembled a radial airplane motor in appearance. It was mounted upright in the same space occupied by gasoline motors in standard [...]
One of the fastest growing sectors of renewable energy resource development is the wide and varied field of Geothermal Heating. No matter the type you choose to match your needs and location, a geothermal installation can be made completely sustainable and is very scaleable. It is likely that the future of geothermal energy will find [...]
In today’s increasingly energy conscious society, one must consider the energy efficiency of every product they purchase. Whether it’s your car’s gas mileage or how much electricity your refrigerator uses, we’ve all become more aware of our energy usage.
There are two main reasons for this, and they’re pretty obvious. One, inefficient energy use costs [...]

The use of photovoltaic (PV) panels is the cornerstone for powering a solar lifestyle. Here’s how the process works:
Photovoltaic panels are joined together to create a solar array
1.First, the photovoltaic panels — or array — collect sunlight and converts it into solar energy.
2.The energy is then stored in special batteries inside the home before [...]
With the solar array assembled, correctly angled and wired, it’s time to connect the exterior wiring to the interior control panels. The solar breaker will first be connected to a circuit breaker disconnect. The energy will flow from the disconnect to a charge controller and then to a battery bank to be stored. When needed, [...]
Proper and perfect insulation of your home is critical in keeping you and your family comfortable year-round. A carefully considered insulation strategy considers air sealing and ventilation to improve your home’s energy efficiency, which reduces your utility bills.

Solar hot water refers to water heated by solar energy. Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage, and a reservoir or tank for heat storage and subsequent use. The systems may be used to heat water for [...]
Definition:
A solar collector is a device for extracting the energy of the sun not indirectly into a more usable or storable form. The energy in sunlight is in the form of electromagnetic radiation from the infrared (long) to the ultraviolet (short) wavelengths. The solar energy striking the earth’s surface at any one time depends on [...]
Negawatt power is a term coined and introduced by Amory Lovins in a 1989 speech. This technique works by utilising consumption efficiency to increase available market supply rather than by increasing plant generation capacity. This “virtual generation” method can supply growth of supply by increasing efficiencies rather than increasing generation.
It has two main uses:-
1. The [...]
