This paper deals with the influence of solar modules soiling on their energy efficiency. Soiling is the term used to describe the deposition of dust on solar modules. Dust, most often contains organic minerals and particles which result from the burning of fossil fuels, etc. In research studies investigating the influence of dust on the solar modules efficiency in the world, in the Solar Energy Laboratory at the Faculty of Sciences and Mathematics in Nis, and in the Solar Energy Laboratory at the Academy of Sciences and Arts of the Republic of Srpska, it was concluded that all types of dust negatively affect the energy efficiency of solar modules, with ash, limestone (calcium carbonate), red soil and sand (silicon dioxide) having the greatest impact.

The potential crisis of energy and the deterioration of ecological environment make the world's cumbersomedevelopment of renewable energy including new energy, including solar energy. Traditional energy in the coal, oil andnatural gas are evolved from ancient fossils, it is collectively referred to as fossil fuels. As the world's energy needscontinue to increase, fossil fuels will also be depleted, it is necessary to fi nd a new energy to replace the traditionalenergy. Solar energy is a clean renewable energy with mineral energy incomparable superiority. Modern society shouldbe a conservation-oriented society, and social life should also be a life-saving energy. At the same time, Premier WenJiabao also proposed on June 30, 2005 and stressed the need to speed up the construction of a conservation-orientedsociety. And solar energy as an inexhaustible new environmentally friendly energy has become the world's energyresearch work in the world an important issue. Is the world in the economic situation to take a simpler, economical,environmentally friendly and reliable building heating and heating energy-saving measures. This paper summarizes thecurrent global energy status, indicating the importance of solar power and prospects. Details of the various solar powergeneration methods and their advantages, and made a comparison of this power generation parameters. At the sametime pointed out that the diffi culties faced by solar power and solutions, as well as China's solar power of the favorableconditions and diffi culties.

Originally, coal was the main source of energy. It remains so throughout the 18th century during the period of the rapid industry development. Later on, oil and naphtha began to be used as energy sources and their usage expanded especially in 19th century. A special feature of the above mentioned fossil fuels is their long creation period – requiring millennia. They are a result of rotting of different plant and animal kinds. In comparison to the period of their formation, the period of their utilization is far shorter. In accordance with a number of existing statistics about 2050 year it may be talked about a depletion of the liquid fossil fuels, also, the world coal supplies are considered to last within the next 200 years. Therefore, the development of nuclear power engineering is considered to be one of the alternatives to generate energy. Recently, the nuclear power energy generation has been denied in many countries because of the risks associated with its generation and because these risks have been confirmed by serious accidents throughout the World. The storage of worked nuclear waste is also a problem and risky. The renewable energy sources are another possibility to generate energy.

The innovation in the energy sector involves the use of renewable resources and the transition to eco-energy, which requires a comparative analysis of the advantages and disadvantages for the economically sound choice when deciding on the energy strategy for each region. The use of alternative energy sources in Russia and the world is analyzed, which brings us to a conclusion that Russia is currently in an intermediate position in this area. Measures are proposed in orderd to strengthen the government support for Eco energy. It is held that the development of solar energy will play the largest role in the innovative development of the Republic of Tatarstan. The article is devoted to the problems of solar energy in Russia and Tatarstan respectively, as well as to the prospects for its development based on the proposed legislative, investment, financial and organizational solutions. The article provides a methodology for the comprehensive and effective adaptation of foreign experience in the field of alternative energy and a roadmap for the implementation.

The constant growth of the world’s population has generated various changes in the use of the diversity of the resources provided to us by the planet. Considering that by properly managing energy in air conditioning systems correctly, it collaborates in the fight against climate change, reducing the excessive use of fossil fuels and, therefore, the emission of CO2 and other greenhouse gases, creating an environment of comfort in industrial sectors, businesses, companies, homes, among others. The objective of this research is to validate the instrument considering the information obtained about smart devices applied in air conditioning systems and their improvement in energy efficiency. The methodology applied consisted of a field study conducted through an online survey that was directed at 226 students and professionals from three provinces of the Republic of Ecuador. To validate the data obtained in the instrument, the exploratory factor analysis was performed also of the principal components in the last phase it was obtained in factor transformation matrix (0.986), which demonstrates the validity of the study. To apply the KMO test and Bartlett’s sphericity, the following ranges (≥0.6) y (<0.05) were considered respectively.

Strictly speaking, all forms of energy are derived from the sun. However, our most common forms of energy, fossil-fuels, received their solar input eons ago and have changed their characteristics so that they are now in concentrated form. It is apparent that these stored concentrated energy forms are now being used at such a rapid rate that they will be depleted in the not-toodistant future. It would be useful to utilize the incoming solar energy directly. The effective use of the sun's energy in agriculture by any economically possible means will help the farmers continue their work with no disruption because of the lack of concentrated form of energy. The fluidyne heat engine utilizes solar energy to pump water. The simplicity, reliability, and low cost of this engine are of primary importance for the farmers in the part of the world whereas solar energy is abundant such as Puerto Rico.

The relevance of the topic is the development of alternative energy and search for new sources of energy as the main world trend of the twenty-first century. Using the energy of earth, wind, water and sun, humanity will stop polluting the environment and save valuable fossil resources. The Republic of Kazakhstan is well known with its stability and successful development. It is quite important not only for the country, but for the whole Central Asian region. Nowadays it is necessary to improve the energy returned on investment, and to make producing it cheaper. Wind power will be nearly very important in coming years. Probably the most established renewable energy source, besides hydro, becomes as cheap as fossil fuels in many markets around the world. The different types of the renewable energy were examined in this article.

Dairymen now have an alternative source of energy to assist them in efficient production of milk. Solar energy is being used to heat water and to space-heat milk houses and milking parlors. Used in conjunction with standard heating systems, solar systems can supply from 30 to 70% of the water- and space-heating requirements on a dairy farm. Tax incentives and rising costs of electricity and fossil fuels are making solar energy systems economically feasible for the modern dairyman. During the 1970s the world has come to recognize the reserves of fossil fuels used for energy are limited. The “energy crisis” caused these sources of energy to spiral in cost. Today, alternate sources of energy are being investigated and some are proving to be economically feasible.

For 100 years, states have put a major emphasis on energy security. This is about to change as a result of five revolutions: US shale gas, US shale oil, worldwide renewable growth, energy efficiency, and energy storage. The world is now facing an unlimited amount of energy and should restrain fossil fuels use to avoid undesirable climate changes. The power of the Organization of the Petroleum Exporting Countries (OPEC) is becoming irrelevant as should, in the future, the concept of energy security. Energy security is still relevant for armies that need oil to power their tanks, ships, and aircrafts. But for how long?
