Exergy of solar radiation
Solar radiation reaching the ground is accompanied with radiation entropy. When the entropy production rate within any solar energy conversion device is to be calculated, the incoming radiation entropy flux has to be known. In this contribution, first it is shown how the radiation entropy flux arriving on earth is to be calculated. Secondly, the interaction between the incoming radiation and the ...

Quantitative assessment of solar energy geo-policy risks
Fossil fuels, such as coal, oil, gas, and wood, are the major part of contemporary energy mix. However, forecasts predict that solar energy will take up to 70% of global energy mix by year 2100. Solar energy has embedded risks, e.g., social, geopolitical, health-related, etc. These risks should be addressed in advance to prevent negative consequences but little research has addressed systemic ...

Prospects of the development of the solar energy industry in the Caribbean
The Caribbean region is a chain of small islands that are vulnerable to the negative impacts of climate change and high oil prices. Renewable energy, or more specially, solar energy can provide a solution to both of these challenges for the Caribbean. Yet despite the positive impact solar energy can have upon the Caribbean, not much is being done to commerciality develop the solar energy industry ...

Georgia Power to expand solar project
Thursday, the Public Service Commission of Georgia approve a plan to expand solar energy share through the utility Georgia Power. The company will have to buy solar energy from energy farm to reeach a 525MW production by 2016. Moreover, Georgia Power has many challenges to come. As two proposals of the company will have to face the Public Service Commission's vote first. Opponents of Georgia ...

Can solar sources meet Australia's electricity and liquid fuel demand?
It is commonly assumed that because of its relatively high solar energy incidence Australia will be able to meet its energy demand from solar sources. However, an examination of evidence on existing and probable future efficiencies and costs indicates that it will not be possible to derive sufficient electricity or liquid fuels to sustain the present high per capita rates of consumption from ...

Performance evaluation of solar tunnel dryer for grape drying
This paper presents the performance of solar tunnel dryer to dry chemically untreated grape. Average air temperature rise in dryer was in the range of 20-21?C above the ambient temperature and it was almost constant in the dryer. The solar tunnel dryer of size 10 ? 3.75 m² is in position to dry 320 kg of grapes from 85% (wb) moisture content to 16% (wb) moisture content within seven days. ...

Role of acridine orange – sodium lauryl sulphate system in photogalvanic cell for solar energy conversion
Energy conversion efficiency was studied in liquid phase photogalvanic cell consisting acridine orange as photosensitiser, NaLS as surfactant and DTPA as reductant. Values of photopotential and photocurrent generated by this system were 746.0 mV and 205.0 µA respectively. The observed power conversion photon energy efficiency was 0.83% and fill factor was determined as 0.56. This photogalvanic ...

Solar Gardens are Gaining Ground in Communities
While the idea of using solar energy appeals to many people, not everyone lives in a place where they can easily have access to it. Many people live in apartments, for example, so unless you convince your landlord to allow you to put solar panels on the roof of your building, you’re out of luck. Many others have heavily shaded houses or roofs and yards that are too small to accommodate a ...

Is Solar Energy the Answer?
Due to the rising demands of electricity consumption brought to us by different factors, the world has faced a serious problem in terms of power shortage. It is because of the occurrence of new technologies and gadgets brought to us by the new millennium. As the growth of population also increases, more demand of electricity usage and consumption is presently rising. As you can see, insufficient ...

Environmental thermodynamic limitations on global human population
This paper examines, from a thermodynamic point of view, how many people the Earth can support. The maximum human population allowed by the natural earth ranges from 300 million millions to 1,700 million millions and will not exceed 1,300 million millions if an ambient temperature of 300 K is accepted. A further increase in population number is obtained for macro-engineered earth when heat pumps ...
