Energy efficiency - the rational use of energy resources - the achievement of economically justified efficiency of using fuel and energy resources with modernization of existing equipment and technologies, ensuring compliance with requirements for Environmental Protection.
Energy saving - implementation of legal, institutional, scientific, industrial, technical and economic measures aimed to accomplish the rational use and economic consumption of fuel and energy resources and involving in economic circulation renewable energy sources.
Energy saving - an important aspect in the issue of natural resource conservation.
Increase in demand for gas and electric power turned out higher than values provided by the "Energy Strategy of Russia."
In 2007, total energy consumption in Russia was around 990 million tons of equivalent fuel. With proper implementation of energy-saving and energy-efficient equipment in EU Member States this figure would fall to a value of 650 million tons of equivalent fuel. In other words, in our country, 35% of the energy is lost. In everyday life we've spent about 40-45% of all the energy produced.
Alternative sources of energy in buildings can be heat pumps, solar collectors and batteries, as well as wind generators.
In 2012, entered into force the first National standard STO NOSTROY 2.35.4-2011 «Green building. Buildings and civil construction. Rating system for evaluation sustainability of residential and public buildings». The most famous equivalent standards in the world are: LEED, BREEAM and DGNB.
Systematic work in the field of energy conservation and energy efficiency in various sectors and spheres of the Russian economy began after adoption of the federal law from November 23, 2009 of No. 261-FZ «About energy saving and about raise of energy efficiency and about modification of separate legal acts of the Russian Federation». The program aims to become a tool for solving large-scale task for reducing energy intensity of GDP by 40% by the year 2020.
Western specialists evaluated the potential of profit from long-term investments in energy efficiency of russian energy as 300 billion dollars.
Starting from the 1970s. many countries have implemented policies and programs to improve energy efficiency. Today, for the industrial sector accounts nearly 40% of annual global consumption of primary energy and about the same proportion of global carbon dioxide emissions. International standard ISO 50001 was adopted and it also regulates energy efficiency.
Improving energy efficiency from 1990 in economies of 14 leading countries allowed in 2004 to reduce energy consumption by 14%, comparing with the level (of energy consumption), which could have occurred without taking measures to improve energy efficiency.
Taking into account the overall global trend in ensuring efficient use of energy, it can be stated, that investments, aimed at developing energy efficiency and of new ways of conservation, increase the energy potential of the country - the main condition for achieving economic growth.
