Using wind and solar renewable energy by enterprises and consumers in terms of the energy management

By

Introduction. More and more leaders realize that the wider use of renewable energy brings many benefits on long-term, both for the enterprises and for the whole society in the process of developing the smart grids. One of the continuing concerns of any leader at any level must be the energy efficiency growth for all the users, individuals or legal entities. A good corporate leader supports a wider use of the renewable energy because thereby he promotes the care for the environment through the clean energy, the green economy idea in general, which will create him a positive image in the community and he will be considered a good representative of “corporate social responsibility”, by reducing the social ethical implications of strategies adopted.

Aim of the study. The more there will be more leaders who will promote the idea of production and use of alternative and renewable energy will be required also a greater involvement of the state in the use of the economic policy instruments in order to increase the investments in the infrastructure, to encourage the innovations in this field and to establish the regulations guiding of the specific markets mechanisms and the responsibilities and roles of each economic subject.

Issues of geothermal and biomass energy efficiency in agriculture, industry, transports and domestic consumption

By

Introduction. Increasing energy efficiency should be a concern for both the firm managers and any leader at any level, given that energy efficiency significantly reduce production costs. An important aspect of this is the use of renewable energy sources, in different types of activities, depending on the possibilities to produce it on favorable terms, to supply at relatively low costs and to efficiently consume it both in the producing units and the households. A skilful and powerful leader will seek and support, through its influence, all the means that determine the reduction of the production costs and obtain a profit as high as possible.

Aim of the study. This paper aims to highlight that a wider use of renewable energy promotes concern for the environment through clean energy, for reducing pollution and for facilitate, in some cases, even the increase of the production with the same costs or lower costs. In agriculture, industry, transports and household consumption, a high importance presents the geothermal energy and the biomass as source of energy.

Metallurgy – an industry between traditional and sustainable management

By

Introduction. Currently, the industry is a very important economic branch because the industrial products have a high share in the total final and intermediate consumption. Apart from the positive effects on the global consumption, the industrial activities have some negative economic and social effects and also on the environment. The sustainable management in industry should increase efficiency and reduce waste, should find new production methods so that the economic growth can be made with fewer natural resources, fewer materials – especially the rare ones, with less energy consumption from traditional resources and with more efficient technologies, with less negative effects on the human health and on the environment.

Aim of the study. The transition to a greener industry is an important issue for all the national economies and it is very important to adapt the legislation to the new trends and standards, to adopt new payment schemes, grants and green funds schemes, so as to encourage the industrial enterprises to increase the efficiency of the total resources consumption, to make the transition to greener activities, to use more green capital inputs, to produce more green products, to increase the collaboration with the public and the private sector.
