Picture 6 represents a system for grey water recycling which deals with the water saving problem.
About 40% of freshwater coming into the average home is used just to flush the toilet. When tucked inside the cabinet below the bathroom sink, the Aqus system cuts that number significantly. Instead of using freshwater to flush, it catches the water that goes down your sink drain, filtering and disinfecting it and then quietly pumping it to your toilet tank. (The recycled water is even safe for toilet-slurping pets.) When there’s not enough wastewater for a flush, Aqus pulls from your plumbing. The system saves up to 14 gallons a day in a two-person house. An alternative for Aqus, which is easier and the nowadays household should profit on maximum, is a low consumption or dual flush toilet.

Huge problem in kitchens is all the waste produced in there. Hence, a practical and sustainable solution should be used for the waste disposals. One of the smaller, simpler products reviewed is the NatureMill automatic indoor composter (figure 4), which serves as a kitchen garbage can: NatureMill uses 5 kWh/month of energy – less than a garbage truck would burn in diesel fuel to haul the same waste.
On figure 5 is shown another sustainable example for composting systems. It is original and well organized system which could be great solution for commercial kitchens.

Considering that the greatest amount of energy of a household is used in the kitchen a more sustainable solution for energy than the ordinary ones – gas, electricity and solid fuel, is needed. Therefore a solar battery (figure 2) can be installed to produce a completely sustainable energy which is also cost saving in long term.
One another solution for not developed countries could be the solar cooker (figure 3). Because of its qualities like simple construction, not expensive, easy installation and sustainability its popularity in the countries from the “third world” grows extremely fast in nowadays.

This is a small but extremely functional kitchen which deals with space problems. It is a compact solution for a student and young people who often change their living places. A one-piece unit containing oven, sink, fridge, table and utility storage can replace the whole trouble in finding, transporting and installing the aforementioned units one by one. It is efficient and not costly decision in a longer run.

We are at a dawn of new light sources competing with each other. Since the new standards were put into effect many manufacturers turned their heads in search of new light sources mostly focusing on LED and all their potential uses. But we are also witnessing creative ideas emerging with the use of previously established technologies and giving them a boost.
A new kind of light source uses LEC technology to create a paper-thin lighting device that is flexible and extremely light weight.  This flat panel light promises 75 percent more efficiency over incandescent bulbs. Potential ideas range from night light panels to lit glass counter tops.
The technology is based on External Electrode Fluorescent Lamp technology, promising directed light and five times the durability of compact fluorescent light bulbs. Originally used for backlights in liquid crystal displays, the unique form factor could be used for a variety of residential, commercial and industrial needs, inside and outside. The LEED approved lighting will also be dimmable, allowing for further efficiency.
