The use of fossil fuels (methane, oil, etc.) is undergoing an unprecedented crisis now. There is the urgent need to search for alternative energy sources. A wide range of degraded organic materials can be effectively used to provide energy together with environmental protection. Soapstock is a hazardous waste containing a high concentration of toxi...

On the basis of comparison of the influence of the stock exchange factors on the pricing of nonferrous metals for medium term with similar results for short term, it has been established that the main attention should be paid to the changes in the pricing environment on the metal market as a function of the prices of exchange traded metals. The sit...

The open trade on the world market is estimated using information of one-day exchange prices of nonferrous and precious metals, oil, reduced crude, and gasoline and the main world stock indices in the time period from January 1, 2009 to December 31, 2015. It is found that the short-term changes in the prices of nonferrous metals are determined by t...
This article presents the first results of the application of the Methodology for Total Management Techniques of Energy Efficiency at the International Health Centre "La Pradera". It was realized an energetic characterization of the Centre, determining the structure of energy carriers consumption. It was conducted a statistical investigation of the...

Results of experimental studies on pyrolysis of brown coals of the Lelchitsy deposit, which were conducted on Laboratory setups in stationary and moving layers for producing high-caloric energy carriers, are presented. The yield of the pyrolysis products is determined; the chemical composition of solid, liquid, and gaseous products of thermochemica...
Energy carriers - either conventional or 'new' ones - have to be provided in large amounts to meet the requirements of permanent availability and reliable supply of electricity. Depending on their state of aggregation, energy carriers are either stored in large masses (if solid or liquid) or at elevated pressures (if gaseous). Both impose the hazar...
With the mass introduction of wind power in Northern China, wind power variability has appeared. In this article, both existing electric heat pumps (EHPs) and coal-fired combined heat and power (CHP) facilities, which are generally equipped with extraction-condensing steam turbines coupled with district heating for space heating purposes, are propo...
