With the rapid development of wind power, randomness and volatility power have also caused severe problems consumption. The phenomenon abandonment is particularly prominent in "three north" areas. environmental protection controllability regenerative electric heating provide a way for absorption abandonment. Therefore, this paper proposes model to promote consumption by using heating. Firstly, ...

Commodity prices tend to be volatile, and volatility itself varies over time. Changes in volatility can affect market variables by directly affecting the marginal value of storage, and by affecting a component of the total marginal cost of production: the opportunity cost of exercising the option to produce the commodity now rather than waiting for more price information. I examine the role of ...

Energy piles are an effective and economic means of using geothermal energy resources for heating and cooling buildings, contributing to legislative requirements for renewable energy in new construction. While such piles have been used for around 25 years with no apparent detrimental effect, there is limited understanding of their thermo-mechanical behaviour. This paper synthesises the results ...

Abstract Replacing coal by electricity projects is one of the national public welfare projects. In field energy conversion, larger number electric heating users is, more favorable it to control air pollution, and significant benefits society, ecological system environment are. This paper put forward a technology for solving restriction on rapid development clean due electrical equipment capacit...

INTRODUCTION Although electrotherapy appears to have particularly interesting applications in the field of postoperative orthopedic rehabilitation, relatively little scientifically based research has been conducted in the area of electrotherapy with regard to safety involving patients with orthopedic implants. METHOD Three electrotherapy forms were tested, such as high-volt stimulation (HVS),...

Food production and consumption is known to have significant environmental impacts. In the present work, the life cycle assessment methodology is used for the environmental assessment of an assortment of 34 fruits and vegetables of a large Swiss retailer, with the aim of providing environmental decision-support to the retailer and establishing life cycle inventories (LCI) also applicable to oth...

For many countries, increasing energy efficiency and reducing greenhouse gas emissions are key countermeasures to cope with the energy crisis and climate change. Of the various heating equipment such as heat pumps, gas-fired boilers, oil-fired boilers, or electric boilers, heat pumps are widely adopted for space heating, water heating, and process heating by households, business, and industry d...

A laboratory equipment for combinations of convective and microwave drying is presented. It was applied parsnips. Lower energy consumption at heating the product intermitted confirmed in comparison to continuous with hot air. In addition, influence process on phenols flavonoids contents were investigated. The results give useful information organisation operating modes vegetables.
