Power generation and distribution networks are built with spare capacity to meet peak periods of energy consumption is usually a time when demand for heating and / or cooling is particularly acute accommodate. Normally, peak electricity demand in some cases last just a few hours every year. And while the networks have always had to cope with peaks in recent years, the electricity consumption during peak hours has increased dramatically in the afternoon. (more…)

The gradual change in the energy consumption pattern of the United States from 1860 to 1990. In the mid-1800s, biomass, principally woody biomass, supplied over 90% of U.S. energy and fuel needs, after which energy biomass consumption began to decrease as fossil fuels became the preferred energy resources. For many years, a safe illuminant had been sought as a less expensive substitute for whale oils. (more…)

The pressure relief valves protect against the devastating effects of the overpressure. Unfortunately there are so careful with the environment and which are not always made leakproof, and can therefore be emitting harmful gases into the atmosphere continuously. While European directives aimed at reducing emissions of gases causing the greenhouse effect based on a share issue (linked to heavy fines for countries that fail), other solutions much easier go unnoticed.
