The common road atlas is now being replaced with more sophisticated and interactive digital forms which in some vehicles are now being built in as standard features. GIS though still a relatively new technology is becoming more and more useful for a vast range of applications which include every day life, science and agricultural fields, and the military. In this assignment, I will touch on the essence of maps, digital maps, and GIS to provide a basic introduction to their uses, advantages and disadvantages. Maps can be presented as different projections which each have their own advantages and disadvantages.
There are cases that are difficult to allocate to a particular one of the above classes. Methods are listed alphabetically within each group. This page uses several technical units. Energy units, definitions and conversions are available on an additional page. Some notes Paradigm change in energy generation In as I write this a paradigm shift in how electricity is generated and distributed is beginning.
In the past it has been generated mainly at large, centralised, power stations with the timing of the generation controlled by the people in charge. With the development of economically competitive wind and solar power the timing of generation is now partly dependent on when the wind is blowing or the sun shining.
In the case of rooftop solar PV power, generated at the point of consumption, the distribution grid becomes, to some extent, redundant. The power grid, for people and businesses with solar power, becomes almost a battery to fall back on as needed.

Abstract: This article serves as an introduction to the FQS special issue "Participatory Qualitative Research." In recent years there has been a resurgence of interest in participatory research strategies.

As wind and solar power make up a steadily increasing proportion of the electricity generation mix, power storage will become increasingly valuable and needed.
In it is very difficult to predict how this may play out, but one thing seems certain; we will see major changes in the next few decades, even in the next few years.
Greenhouse gasses An advantage of almost any method of power production that does not consume fossil fuels is that it need not result in a net addition of the important greenhouse gas carbon dioxide to the atmosphere.
Natural gas including shale gas and coal seam gas is largely methane, which is, volume for volume, a much more potent greenhouse gas than carbon dioxide.
When burned methane produces carbon dioxide and steam. An unknown amount of methane is lost into the atmosphere during fracking, extraction, transport and distribution.
No level playing field Economists, politicians and supporters of fossil fuels often make statements such as "Sustainable methods of power generation cannot yet compete financially on a level playing field with fossil fuel fired power stations".
In practice there is no level playing field! Fossil fuel electricity has only been cheaper than the more economically viable of the environmentally friendly options for example wind and solar power because the fossil fuel power station operators are allowed to dump their waste carbon dioxide, oxides of nitrogen and sulfur, toxic metals and particulate matter into the atmosphere at no cost to themselves.
This same waste is the main cause of man-made climate change and ocean acidificationand of millions of illnesses and deaths each year from air pollution.
In reality, by solar PV and wind power were very economically competitive with new fossil fuel power, even without a 'level playing field'. Nuclear powered electricity would be much cheaper if the power station operators were allowed to dump their radioactive wastes in the sea.
The petrochemical industry would make bigger profits if it could dump its wastes in the most convenient place. If fossil fuel electricity generators were made to dispose of their carbon dioxide responsibly, their costs would increase enormously. No one has yet demonstrated that geosequestration of carbon dioxide from an operating coal-fired power station is viable at any price, and at best, geosequestration is more a land-fill style of disposal than it is an environmentally friendly method.Advantages and Disadvantages of Surveys.

Neutering, from the Latin neuter ('of neither sex'), is the removal of an animal's reproductive organ, either all of it or a considerably large part."Neutering" is often used incorrectly to refer only to male animals, but the term actually applies to both sexes. The male-specific term is castration, while spaying is usually reserved for female animals.
Mar 25, · Introduction For the majority of us, maps represent a useful tool which we often use in daily life be it while navigating new hiking trails or when we are looking for a specific landmark, shopping centre or street name in an unfamiliar town or city.
Describe the advantages and benefits of using descriptive research methods. Describe the disadvantages and limitations of using descriptive research methods. Before considering the advantages and disadvantages of descriptive research, it is helpful to review descriptive research and the terms associated with it, as well as be introduced .
