Concentrating Solar Power Global Outlook 09 - Why renewable energy is hot
What is CSP? CSP (Concentrating Solar Power) systems produce heat or electricity using hundreds of mirrors to concentrate the sun’s rays to a temperature typically between 400 and 1000ºC. There are a variety of mirror shapes, sun-tracking methods and ways to provide useful energy, but they all work under the same principle. Individual CSP plants are now typically between 50 and 280MW in size, ...

South Africa innovates to support soaring renewables growth
South Africa's 2010 Integrated Resource Plan (IRP) targeted 8.4 GW of wind and 8.4 GW solar capacity by 2030 and in 2011 the government launched its Renewable Energy Independent Power Producer Procurement Program (REIPPPP) to accelerate development. The REIPPPP has thus far procured 3.4 GW of wind, 2.4 GW of PV and 400 MW of CSP capacity and has attracted 193 billion rand ($13 billion) of ...

Post Saubhagya – Moving Beyond Connections to Quality of Supply
Distribution, the crucial link between power generation plants and end users, presents a complex challenge that India’s power sector is meeting with only qualified success. Despite being one of the world’s fastest-growing economies, India’s per capita electricity consumption is only about a third of the global average. The rural segment of the population has been most affected ...

CSP cost forecasts undervalue benefit to future grid balancing
CSP generation costs could drop to $77/MWh by 2025 but storage and hybrid solar plants can provide further value by following load, Jose Alfonso Nebrera, Director of Spanish engineering firm ACS SCE, said at the MENASOL 2016 conference on May 26. Global renewable energy expansion is reducing the cost of solar and wind energy while increasing grid intermittency and the need for dispatchable power ...

Biomass and Integration in Future Energy Systems and the Bioeconomy
Biomass was the primary source of materials and energy until the industrial revolution set off a series of major changes around two hundred years ago. In the industrialized world fossil fuels became the primary source for energy in the forms of electricity and heat and provided almost all fuels for transport. However, biomass continued to maintain an important role in the economies in both ...

Alternative matrices for India's future power demands
Against the planned capacity addition of 41,110 MW during the 10th Plan, only 21,180 MW could be added. The plan to alter the power mix by enhancing the nuclear power generation capacity of 4120 MW at current levels to 20,000 MW by the next decade seems too ambitious, with only 1% of global uranium reserves. The exercise to source uranium by signing the 123-Agreement with the USA is held up. With ...

Smart operation of air-conditioning (A/C) and lighting systems for national load management
In the countries of Arabian Peninsula, demand for electric power, primarily controlled by the air-conditioning (A/C) and generally peaking at 15:00 h, is currently growing well over 5% annually. Adaptations of smart operation of A/C and lighting systems in government and institutional buildings that commonly function between 07:00 h and 14:00 h has been evaluated as a technique for national load ...

Effect of exergy optimisation on a cogeneration system's CO2 emissions according to different demand patterns
The objective of this work is to verify how different operational strategies affect the CO2 emissions of a cogeneration system according to different demand patterns. The operation strategies studied were focused in running cost and exergetic efficiency. The results show that the optimal exergetic efficiency strategy generated the highest emissions reduction. The operation with the highest ...

Environment risk and cogeneration in China: the case of Zibo Huantai district
With the economic development, the environment protection problems become more and more serious and the environment protection deterioration risk has been exacerbated in Zibo City, China. Many small heating boilers are used to supply heat in Huantai district of Zibo, which have low efficiency of energy consumption and cause serious pollution. With the analysis of the thermal power demand and ...

On the over-investment in automotive technology
This paper discusses the reasons for continuing very high levels of R&D spending in the automotive industry in spite of the fact that both the automobile and the market for automobiles are widely considered to be mature. Most R&D appears to be product and not process-related. The microelectronics revolution has to some extent rejuvenated the automobile. Besides that, government regulation has ...

Solar Microgrids and How They Help Our Communities
Solar energy is a great way for both homeowners and eco-friendly businesses to increase their energy independence. But most solar arrays remain connected to the grid, which means they lose some of their convenience when the grid loses power. This is because solar panels wired through the grid don’t really “store” energy. They work in tandem with the power grid to supply ...

Application! Panel Energy Meter
Application! Panel Energy Meter Panel energy meter is a common electric energy metering and billing device, mainly apply to electricity system, industry production, building electricity metering and so on. Generally installed on the cabinet door of the power cabinet. The LCD disply of panel power meter is partially exposed outside the power cabinet for easy data viewing. The panel power meter is ...

Scenarios for a worldwide deployment of nuclear power
The growing worldwide demand for energy must be controlled. However, even in the event of voluntary policies to dampen energy demand, it is hard to imagine that the demand could be less than twice as much as today's by 2050. We feel it is necessary to satisfy this demand. It is obvious also that greenhouse gas emissions must be reduced in order to limit the severe consequences that they entail. ...

Understanding the demand of an electricity meter
The demand of an electricity meter refers to the maximum average value of the electrical load within a certain time interval. In the power industry, it is common to use a 15-minute interval for measurement and calculation. The maximum average value within this time interval is the demand of the electricity meter, and there are two common calculation methods: interval-based and sliding-scale. The ...
