This article presents reasons behind growth of Princeton Power. Princeton Power derives from a patent for a proprietary technology and a class that inspired students to form their own companies. Its development so far reflects a growing interest in finding better ways to harness alternative energy sources, but at its core, the company represents the desire of four young men to try something new. Originally, Princeton Power planned to build large inverters for the power grid, but the company discovered a fast-growing market for smaller inverters that can convert the output of solar cells and wind generators into usable capacity. Princeton Power focuses on the nuts and bolts of its systems. It is exactly the type of work engineers are trained to do-focus on real problems and solve them. The company has also teamed with Gaia Power Technologies Inc. of New York, to develop controllers for battery backup systems that must interface with the electrical grid. Not only will the systems provide backup power in the event of an outage, but customers can use them to capture electricity at night, when rates are cheaper, and then use the electricity during peak hours when rates are high.

Subject Global silver market dynamics. Significance The price of most commodities has risen since 2015 but not that of silver. Indeed, the price has barely changed in two years and has fallen nearly 3% this year. Investor interest in exchange traded products (ETPs) in 2016 was not sustained in 2017 but while low volatility discouraged investors, manufacturing demand rose. Strong demand from the solar panel industry is surprising sceptics. Impacts After two years of unusually strong zinc prices, large projects will come online, increasing the amount of silver mined as a by-product. US tariffs on imported solar cells will boost demand for alternative energy sources, eventually hurting silver consumption. The largest silver exchange, the Chicago Mercantile Exchange, will offer option trading in smaller amounts, matching traders’ preferences. Increased silver use in light karat gold jewellery in India and China will support demand for the metal.

Subject. The article discusses limited sources of energy nowadays and an ongoing survey of new ones. I focus on fuel and energy complexes worldwide and in Russia. Objectives. The study is to analyze the future use of alternative energy sources in the fuel and energy complex nationwide and worldwide. I review the existing energy sources of the fuel and energy complex in the global and regional markets, specifically the alternative ones. Methods. The study relies upon methods of statistics, analysis and systems approach. Results. The article demonstrates that the fuel and energy complex strongly depends on the current situation in the energy resource market, which is difficult to forecast. If we continue relying on traditional energy resources, we get exposed to some risks affecting the sustainable development of the economy. Russia should diversify the power engineering sector by developing alternative energy sources. The article sets forth the economic rationale for alternative sources and key steps Russia shall make. Conclusions and Relevance. Considering the current situation in the energy balance, alternative energy is what any advanced society seeks for, being supported by manufacturers, governmental institutions, and researchers, though low profitability and high infrastructure costs impede its development. In Russia, these challenges are even more palpable. However, even now Russia is able to find alternative energy solutions. In addition to advantages of alternative energy, which is globally proclaimed, they will also help Russia diversify and update the economic system.
