Biogas and Biomass Implementation in Rural Areas

Abstract Advances in energy demand in rural areas cannot be dissociated from agricultural modernization, large estates, mechanization of labor and reduced investment in small production. The use of biogas together with biomass are the most cost-effective ways for the small producer, as it has a high calorific value. In the case of biogas the procedure is performed by combining a compressor and a chiller, allowing the gas enter the reactor and burn together with the air stream. The use of these techniques is an auxiliary way to reduce the cost of the producer to produce a certain crop, besides allowing a participation in the final energy supply, so that the utilities have an alternative to distribute the surplus energy to another region, serving thus a wider range in the rural area.

Public Policies to Be Implemented to Encourage the Use of Renewable Energy Sources in the Rural Area of Paraná

Abstract Around the world there's a rising interest in the installation of renewable energy sources due to their ecological, economical, political and social advantages. In this article is studied specifically the case of the incentive towards the installation of these sources in the state of Parana's rural area, where they wouldn't just be ecologically interesting, but also would help the improvement on the living conditions of the rural producers, promote income distribution and would cause an increase on the power supply, this way reducing the tariff. However, the problem arises in the acquisition of the energy generator, since even though they are interesting for the rural producers, these sources are majorly too expensive and end up being beyond their purchasing power. Based on that, this article brings a selection of public policies that could make the use of these sources viable in the rural area of the state, based on the experiences of other countries who face or have faced in the past similar difficulties, like China or India, and countries who have become reference in the matter, like Germany.

Integration of Renewable Energy Sources to Operate in Microgrids in Rural Zones in Brazil

Abstract In a world where technology is even more essential, quality and reliability of electrical system are fundamental. In Brazil, country where most of the energy is produced thought power plants, the existing distribution network is overwhelmed and the needs for the consolidation of distributed generation is growing. Wind and Solar power generation from biomass and another renewable sources are one alternative to power plants, which requires large areas and massive investment. The renewable energy sources mentioned may be assembled in a way to generate reliable energy to properties far from the cities, such as rural zones, where often energy from power plants doesn't gets to. Distributed generation allows quick development of Brazilian farming and guarantees to the farmer independence from the energy dealerships. Microgrids assembled with renewable sources are one sustainable option and benefits Brazilian economy and society.
