The Energy

The power plants, exactly receive prominence for its great importance in the process from creation of the sustainable development of any nation, and for its importance as source competitive advantage for the productive units in the market. You vary clean power plants are being developed and used to cure this Brazilian deficiency. But one of these power plants calls the attention for its efficiency as alternative source of energy, in the containment of costs with electric energy and others in the process of generation of auto-sustainable energy, promoting redirecionamento of energy comings of hydroelectric plants and diminishing costs of energy for the companies, is the solar or fotovoltaica energy. The fotovoltaica solar energy, fruit of the direct conversion in electricity, the form that has presented the development more notable in recent years. The fotovoltaicos systems have received great attention from the community international technique. As consequence, they have been pointed as ones of the great chances in the energy sector in this principle of millenium.

Systems of fotovoltaica generation have been used of two forms: separately and in co-generation. In companies who are in remote localities, that not they count on supply of conventional electric energy, in regions of difficult access to the electric net, and in great urban centers that search alternative power plants for the high indices of consumption, isolated fotovoltaicos systems can be the solution. In this in case that, the generated energy must partially be stored in banks of batteries. The excess of energy generated during periods of raised solar radiation, or low consumption, can be stored, for use during the night, for example. Fotovoltaicos systems can be the principal source of energy for enterprise consumption. To another possible situation it involves the use of a fotovoltaico system of generation as a source of electricity hardwired in parallel with the electric net, in co-generation. In this system, the consumer primarily uses the energy generated local in fotovoltaicos panels.

Energy Efficiency

The 5 of March Energetics is celebrated anywhere in the world the Day of the Efficiency, a date to reflect on the habits of the citizens against the sustainable and rational use of the energy and the commitment of companies, institutions and governments with the reduction of gas discharges of greenhouse effect. This day has its origins in 1998 in Austria, soothes of the first international conference of Efficiency Energetics where more than 350 experts and leaders of 50 countries they discussed strategies to face the energy crisis and to approach possible solutions. During this day in numerous forums and organisms one works and it discusses as they are the best ways to live better and to continue with our present system of life reducing the power consumption in all the scopes, without for that reason losing quality, productivity and comfort. This year comes marked by the approval in the congress from the new project star of Rodriguez Zapatero, the first draft of the Law of Sustainable Economy that feels the bases for a new power model been becoming in the security of provision, the economic efficiency and the respect to the environment, determining the objectives of power saving for the Administration. The Government incorporates to the legal ordering measured that allows us to fulfill the commitments contracted with the European Union for year 2020 consisting of trimming the carbon dioxide emissions (CO2) in a 20%, to improve the efficiency energetics in another 20% and that 20% of the energy that consumes come from renewable sources. In order to achieve these Spain objectives he must realise a concerted effort working in the development of technologies, efficient products and services in the fields with potential major of energy saving, fomenting responsible habits, that do possible a smaller power consumption, improving the competitiveness of the companies and the quality of personal life.

Generated Electric Energy

This work was carried through with intention to present solutions techniques for a beer industry, giving a viable destination to its generated residues. The Project aims at to reaproveitar these residues for the production of biogs through biodigestores, and thus to make possible the use of the same as half of if converting this biogs into electric energy, brightening up the generated ambient impacts. 1. INTRODUCTION Currently diverse industries of innumerable branches, are if dedicating to the related questions the support. Ones of the forms to make with the same ones becomes each time more sustainable is to consider alternative solutions in set with better gerenciamentos of its rejeitos, similar to improve them economically, socially and ambiently. With the purpose to minimize the impacts caused for the generated liquid rejeitos with the manufacture of the beer, and to promote the development and the efficient use of the biomass generated I assist with it of biodigestores, and thus to apply technologies to convert gas generated in electric energy as sustainable source. The present project to interdisciplinar has as objective to carry through sustainable techniques, integrating knowledge acquired in and integral, Physical Differential calculus applied and Chemical Analytical, you discipline then given.
