In suburban Skolkovo, under the "City of the Future", is planned to construct at least one million square meters of housing. Yet know the exact parameters of these buildings, but it would be logical in their construction use innovative technologies, including energy saving. Saving energy - the basic idea of "future cities", created in different countries. For example, a Japanese construction firm Shimizu Corporation has developed conceptual design, which is an island in the center of which is a skyscraper height of one kilometer, it will be able to live in some 30 thousand people. In the lower part of the building will be office space and agricultural farms. The main feature of the city, a skyscraper - a complete self-sufficiency in energy. Its sources are solar, wind and thermal installations. Use of natural energy sources - One of the main features, which emphasize the developers of similar projects from different countries.

Some of these ideas have their practical application. For example, a Danish company, velux, a manufacturer of roof windows, implements are currently building the concept of "model home 2020. Within its framework in different parts of Europe are being built or already built homes with minimum energy consumption. For example, a feature of such buildings are remote-controlled skylights. They will be driven by solar energy, and should, depending on time of day and weather to pass the maximum amount of daylight in the room. Solar energy is a central and primary source of supply in such homes, and are used for lighting and heating.
