The principle is very easy:

1: insulation of wall, windows, doors

2: modern heating technology with high efficiency

3: short time interval ventilation 3-5 times per day only for some minutes, so called in rush airing

4: solar techniques for heat and/or current

Have you looked into LEED certfications ?

Energy is a precious commodity, and as such must be salved. Choose renewable generation sources is a wise decision and very proper, as much as possible to avoid any waste. On the domestic front, in our everyday life, we can through some simple steps to reduce energy loss and do well not only the Earth, but also to our pockets. Electricity, heating, water and food are the critical points on which we can take action to improve our energy efficiency. Starting with the warm-up, according to estimates of the largest consumer groups accounts for 79% of total energy expenditure in the home, we will see some practical tips to reduce our use. To reduce slightly above the temperature in the room, just a degree, it may already ensure energy savings of 6%; The windows are one of the main exit routes for heat. Against this can waste you can resort to the use of double-glazed windows can effectively isolate external drafts.To use more energy-saving bulbs. Remember to turn off the light in the room from which we are emerging. When selecting the fridge first aspect to consider is the family's needs and avoid models that go beyond our own needs and placing it away from sources of heat that can reduce efficiency. Another aspect to consider is the table of consumption (available now for all new appliances) and the frost-free feature, which prevents the formation of frost. During the cleaning of the teeth, hands or showering, keep the tap running only when needed, eliminating the need to scroll unnecessarily.In kitchen already the choice of the oven can bring the first benefits, using an electric ventilated remembering to open the fewer times you can the door. To close a small note on the television. If you look at each of your TV, maybe even on the same channel us to gather together in the vision with our family?

Dear @Hossein, have you seen this thread!?

Some literature on this issue follows!

https://www.researchgate.net/post/What_is_the_most_effective_way_to_reduce_energy_consumption_in_buildings

I followed this subject for many years upon teaching 2 courses which contain discussion of energy & energy alternatives as well as the trends of energy usage & "energy saving". I must say that most of the talk about energy saving involves bright ideas which have not been applied on significant scale. The much needed applied research in this area is not supported well because of 2 factors: 1) the influential countries in this world do not consider this research as top priority because they simply control the market & the prices of fossil fuels. 2) the giant companies involved in the production & selling of fossil fuels do not want to see progress in energy alternatives & energy saving because this will result in reduction of their profits and will ultimately lead to their downfall.

1. Introducing solar power plant in home;

2. Newest green technology friendly home;

3. Giving importance to other non-renewable sources of energy; etc. are some of the major solutions.

Hi

1. Hire a qualified company to conduct an energy audit of your building.

2. Weatherize and insulate your building.

3. Replace old appliances with ENERGY STAR appliances.

4. Replace air conditioner units with evaporative coolers, attic fans, or whole-house fans.

5. Replace old heating units and water heaters with high-efficiency systems.

6. Install solar tubes to reduce the need for indoor lighting, particularly in interior rooms.

7. Install awnings, tinted window film, and green cover (trees, vines) to reduce a building's heat gain.

very year, much of the energy consumes is wasted through transmission, heat loss and inefficient technology -- costing American families and businesses money, and leading to increased carbon pollution.

Energy efficiency is one of the easiest and most cost effective ways to combat climate change, clean the air we breathe, improve the competitiveness of our businesses and reduce energy costs for consumers.

Dear Krishnan,

the lamp project is of high importance. In my country Germany old fashioned glow lamps are forbidden to be produced and sold, of course with a lot of protest from the users who loved "the old warm light". So the industry started to change the light color  by filtering and gas content to produce lower light temperatures, and they have success.

Solar energy, 

(Sorry I have wrongly pasted this answer _ This is for transportation)

If people cannot travel easily within a city they may miss opportunities to access employment, education, health, cultural and recreation facilities, or they may simply find it difficult to meet each other socially. Their choices may be restricted, they may waste time, and they may suffer frustration and stress in travelling. Employers in cities depend on effective transport for their workforce, their supply chains and their customers. The ease with which goods can be transported between suppliers, to retail centres and to homes affects both their price to customers and often the  financial success of manufacturing and retail businesses. When the business community are asked how cities could be improved, transport links ar

with reduce the ways that energy is lost

Yes, reduction of energy losses is a good way for energy saving!

Energy savings is effective using a Wireless Sensor Network with multicast communication protocol, controllers, sensors and a control algorithm that switches a relay on or off according to room occupancy. A WSN for building monitoring based on cluster formation of nodes in a room aggregates temperature, humidity and light sensitivity data, displays curves and stores data in a database. An approach to operate a ZigBee based WSN in a way that is energy autonomous and maintenance-free, using indoor light energy harvesting, and a system level model for energy harvesting
