As the positive and important supplement to large-scale power generation, distributed generation (DG) will become key measure to promote energy conservation and solve the problems of climate change in China. Due to absence of universal authoritative definition of DG, this paper summarizes the basic characteristic of DG based on the definitions in typical countries (or organizations) and carried out general definition of DG considering our national conditions and power grid features. From the views of resource, incentive policy and industry, this paper analyzed the fundamental for DG development and compared the development status in typical countries.

Industrial Use

The Mahanadi river faces large-scale ecological disaster due to a variety of anthropogenic stresses. A prime factor is rapid industrialisation and coal-fired power generation plans that are being encouraged by the states of Odisha and Chhattisgarh. These are not only impacting the flow of the river’s waters and damaging the health of its basin but have also made the area susceptible to climate change. The industrial growth-based development has already polluted the Mahanadi to an irrecoverable extent. The over-allocation of water to industries has adversely effected the region’s irrigation and agriculture leading to a bitter contestation between industry and the farming community. As this comment emphasises, both state governments are taking advantage of the Mahanadi river for industrial use to maximise revenue generation but are at the same time are being insensitive to the adverse environmental and ecological consequences that such exploitation will surely lead to.

The Distributed Generation can enhance the system power supply reliability and alleviate the pitch peak and restricted transmission capacity caused by large-scale wind power grid connection and other problems. In Fuxin, the system power supply is inadequate; the wind power integration is restricted and there are rich wind power reserves. Based on the current situation, this paper analyzes the necessity and feasibility of developing the distributed wind power in Fuxin and provides advisory opinions on the development sites and mode of wind power generation.

Impacts Of Climate Change

Exegesis: This exegesis is based on the production of three features that explore local impacts of climate change. The features are part of a journalism research project that investigated the question: how can journalistic practice generate an accurate, balanced account of climate change issues in Australia? The journalist rejects an approach that positions environmental reporting—or the ‘green beat’—as a form of advocacy journalism. In contrast, the researcher positions her journalism practice within mainstream Australian journalism. The researcher sets out to produce reports, which adhere to the conventional journalism norms, including those of ‘balance’ and ‘accuracy’. She explicitly critiques and rejects the phenomenon known as ‘balance as bias’, explored by Boykoff and Boycoff (2004) which, by over accessing climate sceptic sources, obstructs the reporting of climate change as an important economic, social, political and environmental issue. This exegesis explains and defends a different approach that focuses on local reporting rather than large-scale events in distant places. Robert Entman’s definition of framing is used to explain how climate change issues were addressed in each narrative.

<p>Climate change is expected to change the pattern of rainfall resulting in changed flood magnitude. However, in large part due to interannual variability, identifying a climate change signal in flood magnitude remains difficult. As an alternative to investigating trends in flood magnitude, it has been suggested that trends in flood timing, that is, the day of annual streamflow maxima, may be a detectable trend due climate change.</p><p>Here, using high-quality data from around the world, trends in flood and center timing are investigated. We begin by standardizing the data on a local definition of water year. We find an interesting property, that after standardization, the flood and centre timing of streamflow can be approximated by a normal distribution. Moreover, we find that without the standardization on local water year the calculated trend can reverse. We proceed by analyzing trends in centre and flood timing globally using linear regression.</p><p>Results are commensurable with large-scale climatic change. But, unlike changes in extreme rainfall, trends are not spatially consistent. Flood timing is shifting to earlier in the year in the tropics, and later in the year in the extra-tropics, consistent with changes in mean rainfall and flood magnitude. There is evidence of a reversal of trends post-drought, suggesting that the mechanisms controlling flooding at a catchment scale are changing as a result of climate change. It is concluded that trends in flood timing are related to flood generating mechanisms, and largely modulated by changing antecedent moisture conditions.</p>

Impacts Of Climate Change

One of the most obvious and expected impacts of climate change is a shift in the distributional range of organisms, which could have considerable ecological and economic consequences. Australian waters are hotspots for climate-induced environmental changes; here, we review these potential changes and their apparent and potential implications for freshwater, estuarine and marine fish. Our meta-analysis detected <300 papers globally on ‘fish’ and ‘range shifts’, with ~7% being from Australia. Of the Australian papers, only one study exhibited definitive evidence of climate-induced range shifts, with most studies focussing instead on future predictions. There was little consensus in the literature regarding the definition of ‘range’, largely because of populations having distributions that fluctuate regularly. For example, many marine populations have broad dispersal of offspring (causing vagrancy). Similarly, in freshwater and estuarine systems, regular environmental changes (e.g. seasonal, ENSO cycles – not related to climate change) cause expansion and contraction of populations, which confounds efforts to detect range ‘shifts’. We found that increases in water temperature, reduced freshwater flows and changes in ocean currents are likely to be the key drivers of climate-induced range shifts in Australian fishes. Although large-scale frequent and rigorous direct surveys of fishes across their entire distributional ranges, especially at range edges, will be essential to detect range shifts of fishes in response to climate change, we suggest careful co-opting of fisheries, museum and other regional databases as a potential, but imperfect alternative.

Carbon Dioxide Co2

Coal is an abundant, widespread, cheap energy source and contributes to 39% of the world’s electric power generation. Coal releases large amounts of carbon dioxide (CO2), which is believed to play a major role in global warming and climate change. To de-carbonize power generation, three distinct carbon capture technologies are in varying stages of development. These include pre-combustion carbon capture through the use of integrated coal gasification combined cycle (IGCC), post-combustion carbon capture from a pulverized-coal (PC)-fired power plant flue gas using monoethanolamine (MEA) or ammonia (NH3), and oxy-combustion technology. In the latter technology, oxygen is first separated from nitrogen in an air separator unit and used for combustion of coal in a conventional PC boiler. With oxy-combustion technology, the resulting flue gas is predominantly CO2, which makes CO2 capture easier than in the PC-MEA case. This paper discusses the development status as well as the advantages, limitations, performance and economics of each technology in regard to the capture and non-capture cases.

Generation Technology

Photovoltaics is not the only means of using sunlight to generate electricity. Another major solar technology is called “concentrating solar power” or CSP. CSP technologies use concentrating optics to generate high temperatures that are used to drive conventional steam or gas turbines. CSP is generally considered a central generation technology, rather than a source of distributed generation. That is, a large amount of power is generated in one location, with transmission and distribution to the various points of use, rather than generating small amounts of the power at numerous points of use. Because of this feature, CSP is predominantly a utility-scale source of power.
