Hydro Electric Power Developments

The US’s demand for energy increased to fuel World War II because the Axis nations had three times more available power than the US. Shipyards, steel mills, aircraft and automobile manufacturers, and chemical companies all required vast amounts of energy. Additional dams made it possible for the […]

Smart Meter implementation

Major smart meter manufacturers have a history in the traditional metering market and were earlier movers into the smart meter market. All either produce more than meter products and/or have formed collaborations with other smart grid companies to have connections at all parts of the smart grid […]

Natural gas demand and consumption

Natural gas is a gas primarily consisting of methane with zero to 20% ‘higher’ i.e. more complex oil and gas in the mix such as ethane. The natural gas is referred to here is natural gas located deep in the earth known as thermogenic gas created from […]

Thermal Desalination Technology

Thermal Thermal desalination exploits the fact that water molecules vaporise at a lower temperature than dissolved salts and other molecules. Therefore, feed water can be heated and then evaporated to separate out the dissolved salts from pure water. Three different thermal desalination technologies have emerged: multistage flash […]

Classifying water pollution

The major sources of water pollution can be classified as municipal, industrial and agricultural. Municipal water pollution Municipal water pollution consists of waste water from homes and commercial establishments. For many years, the main goal of treating municipal wastewater was simply to reduce its content of suspended […]

Hydroelectric resources

The theoretical size of worldwide hydropower is about 3,000 GW, four times greater than the capacity that has already been exploited. However, the actual amount of electricity that is likely to be generated by hydropower will probably be much lower than the theoretical potential because of environmental […]

New Technologies in Wind Turbines

With the wind industry nearing maturity, most research developments are focused on reducing cost and increasing the efficiency and performance of existing models, or on developing models for the offshore market. Direct drive turbines Most wind turbines use a gearbox to convert a rotor’s speed into high […]

Development of the single global coal market

The existence of a single market arose from the growth in seaborne coal trade brought on by the combination of firstly, growth in the demand for coking coal in the 1960s and secondly, sharply rising oil prices during the 1970s. Before 1960, international coal trade had been […]

Renewable Energy Challenges

Integration costs Costs to integrate wind and solar have been estimated in a few studies, but depend largely on local weather conditions. However, these studies are mainly conducted for several wind farms over a large spatial scale. There are fewer figures for the cost to integrate solar […]

Greenhouse effect

The earth is warmed by radiant energy from the Sun. Over time, the amount of energy transmitted to the earth’s surface is equal to the amount of energy re-radiated back into space in the form of infrared radiation, and the temperature of the Earth’s surface stays roughly […]

Deterministic and probabilistic estimation of reserves

Estimation of reserves is done under conditions of uncertainty. The method of estimation is called deterministic if a single best estimate of reserves is made based on known geological, engineering, and economic data. The method of estimation is called probabilistic when the known geological, engineering, and economic […]

Electric vehicles as Energy Storage

Electric vehicles are a potential mobile storage for grid electricity. Three electric vehicle configurations have been identified to date: hybrid electric vehicles, which are not grid-connected and are entirely reliant on fossil fuels; plug-in hybrid electric vehicles, can be charged using an external power sources and can […]

Historical Analysis – Russian Coal Markets

What were the views of Russia’s coal industry 5 years ago? Read it below. Russia ended 2005 with its seventh straight year of growth, averaging 7% annually since the financial crisis of 1998, although high oil prices and a relatively cheap rouble are important drivers of this […]

Development of Wind Turbines

With advances in the wind industry, the focus of manufacturers is now on reducing costs and increasing efficiency. They are achieving this objective in a number of ways, for example, developing new technologies to power and de-ice turbines, building larger turbines, which have lower operating and maintenance […]

Grid Balancing

A problem is the current grid system is based on traditional fossil fuel plants generating electricity to meet electricity demand. Demands for power vary greatly during the day and night, and they vary considerably from season to season. Three main demands have been recognised: base load demand, […]

The Japanese Transmission System

Although the Japanese transmission and distribution system has been integrated at the national level since 1958, it comprises two geographically separate networks each operating at different frequencies. The Chubu, Hokuriku, Kansai, Chogoku, Shikoku and Kyushu EPCo networks covering Kyushu, Shikoku and southern Honshu operate at 60 Hz […]

The Indian Transmission System

The transmission systems of India developed in different ways depending on the growth and development of the generating facilities and the load centres. At the start of development where hydro power was the predominant source of energy long distance transmission lines were built to deliver power to […]

International Coal Trade

The international hard coal market has seen profound structural change in recent years, marked, first, by ongoing supplier consolidation in Western exporting countries and, second, by a rise in the importance of the former state- trading companies in the transformation states as world market suppliers. Australia is […]

Examples of environmental degradation

James Bay, Quebec The most obvious impact of hydroelectric dams is the flooding of vast areas of land, much of it previously forested, inhabited or used for agriculture. The size of reservoirs created can be extremely large. For example, the La Grande project in the James Bay […]
