The Cost

Generating electricity from the sun using a combination of a compound parabolic concentrator (CPC) and a thermoelectric module (TEM) has been studied. The system was modeled, analyzed, and tested. The model equations and the methodology used for the demonstration are presented and experimentally validated. The experimental setup comprised a manually fabricated CPC placed on a commercially available TEM. The results showed that the combination can generate and sustain enough power for a small appliance. It was also shown that there is enough dissipated heat from the system, which could be harnessed for additional uses. The cost is still high, about $35/Wp, but if credit is given for the thermal energy the initial cost goes down.

Energy From Waste

This paper is regarding the reduction in the cost of electricity generation. This is achieved by using the proposed new mechanics/mechanism/machines as an intermediate, in the process of converting the source energy (Both Conventional Sources of Energy and Non-Conventional Sources of Energy, mainly solar energy and thermal energy from waste or the electricity itself) to electrical energy at truncated charge.

With the advance of green energy; many properties and houses installed solar panel for electricity generation either to reduce the cost of the electrical bills or to prevent the global warming or environmental protection reasons. It is supposed to be more convenient to connect this power source to all the appliances in the house or property, because the cost of connecting this power source to operate few appliances is not a desirable to households. Since these sources like solar panels, wind turbines, hydropower from water turbines,…etc. need batteries to store the energy when they used by end-users to provided energy when the source of alternate to the down state (cannot generate power). For example, when the sun set, or the winds and the water current calm.

Almost All

The Greenhouse Effect acts to slow the escape of infrared radiation to space, and hence warms the atmosphere. The oceans derive almost all of their thermal energy from the sun, and none from infrared radiation in the atmosphere. The thermal energy stored by the oceans is transported globally and released after a range of different time periods. The release of thermal energy from the oceans modifies the behaviour of atmospheric circulation, and hence varies climate. Based on ocean behaviour, New Zealand can expect weather patterns similar to those from 1890-1922 and another Little Ice Age may develop this century.

Fossil Fuel Energy

The Sun’s spectrum on Earth is modified by the atmosphere, and is harvested either by generating heat for direct use or for running heat engines, or by quantum absorption in solar cells, to be discussed later. Focusing of sunlight requires tracking of the Sun and is defeated on cloudy days. Heat engines have efficiency limits similar to the Carnot cycle limit. The steam turbine follows the Rankine cycle and is well developed in technology, optimally using a re-heat cycle of higher efficiency. Having learned quite a bit about how the Sun’s energy is created, and how that process might be reproduced on Earth, we turn now to methods for harvesting the energy from the Sun as a sustainable replacement for fossil fuel energy.

Описаны конструктивные особенности трехвходовой аксиальной генераторной установки (ТАГУ), преобразующей кинетическую энергию ветра и световую энергию солнца и суммирующей механическую, световую и тепловую энергию с одновременным преобразованием полученной суммарной энергии в электрическую. Показаны преимущества ТАГУ перед двухвходовыми генераторными установками. Дополнительное включение стабилизатора напряжения в схему ТАГУ позволило расширить область применения стабилизированной трехвходовой аксиальной генераторной установки за счет стабилизации ее выходного напряжения. The design features of the three-input axial generating installation (TAGI), which converts the kinetic energy of wind and light energy of the sun and sums the mechanical, light and thermal energy with the simultaneous conversion of the total energy into electrical energy, are described. The benefits of TAGI in front of the two-input generating installation shown. The additional introduction of a voltage regulator into the TAGI scheme allowed to expand the scope of the stabilized three-input axial generating installation by stabilizing its output voltage.

ABSTRACT The main objective of this work was to identify and analyze the potential of forest biomass of Eucalyptus sp. such as thermal energy source for industrial use in place of fossil fuels. Two cases were analyzed: the first one estimated the total demand for forest biomass to replace the main fossil fuels in Brazilian industrial sector, with scenarios of 100, 75 and 50% replacement; in the second, it was calculated the cost of each fuel for producing ton of industrial steam (thermal energy) for a dairy industry, in order to verify the competitiveness of forest biomass compared to fossil fuels. The results showed that the areas demanded to replace 100, 75 and 50% of the analyzed fossil fuels were, respectively, 2.9, 2.2 and 1.5 million planted forests hectares, and the steam ton cost ratio using the woodchips was at least 34% lower than with other fuels, which corroborates the substitution potential in this sector.

Solar energy is the most abundant, useful, efficient, and environmentally friendly source of renewable energy. In addition, in recent years, the capacity of photovoltaic electricity generation systems has increased exponentially throughout the world given an increase in the economic viability and reliability of photovoltaic systems. Moreover, many studies state that photovoltaic power systems will play a key role in electricity generation in the future. When first produced, photovoltaic systems had short lifetimes. Currently, through development, the technology lifecycle of photovoltaic systems has increased to 20–25 years. Studies showed that photovoltaic systems would be broadly used in the future, a conclusion reached by considering the rapidly decreasing cost of photovoltaic systems. Because price analysis is very important for energy marketing, in this study, a review of the cost potential factors on photovoltaic panels is realized and the expected cost potential of photovoltaic systems is examined considering numerous studies.
