Market continuum within the United States natural gas industry

From total regulation in 1970 the market has evolved into partial deregulation, with varying degrees of market opening at the different stages of the industrial process. This has happened in 3 stages; wellhead deregulation, pipeline reform and finally unbundling gas services. At the retail level, reforms and restructuring have occurred on a piecemeal basis. For […]

Unproved Probable Reserves

Probable reserves are those unproved reserves which analysis of geological and engineering data suggests are more likely than not to be recoverable. In this context, when probabilistic methods are used, there should be at least a 50% probability that the quantities actually recovered will equal or exceed the sum of estimated proved plus probable reserves. […]

The Spanish Wind Power Manufacturing industry

The growth of activity in the wind energy field has provided a powerful impetus to the development of the Spanish wind industry, covering not only the manufacture of complete wind turbines but also the manufacture of components for the wind industry: blades, generators, gearboxes, towers and wind sensors. The service sector (installation, maintenance, and engineering) […]

Wind Power in Denmark

After 6 years of marginal growth, the Danish wind industry experienced strong growth in 2009 with 294 MW of new installed capacity. The bulk of this, 209 MW, was new offshore capacity, resulting in a total installed capacity of 3,410 MW at year end. In 2009, the share of total energy production in Denmark for […]

The evolution of Renewables Portfolio Standard Policy in the United States

A major difference between the US and Europe is that US renewable energy policy has been driven by the states, and not the national government. Although states have developed a broad range of renewable energy incentives, such as tax incentives, rebates, loan programmes, public benefits funds, RPS systems have emerged as the primary state-level renewable […]

The feed-in tariff in Europe

In contrast to the US, most European countries have adopted feed-in tariffs. While RPS policies typically seek to create electricity price competition, feed-in tariffs require utilities to purchase power from renewable energy generators at a fixed price. These fixed prices are structured either in the form of long-term payments based on generation cost (as in […]

Rising Demand for Desalination

There is a growing need for desalinated water from the general public, which has a greater understanding of water issues and often demands high quality potable water. Several industries require ultra pure water produced from desalination, and these industries are growing e.g. pharmaceutical and semi-conductors, and equipment can now measure contaminants at very low concentrations. […]

The world’s water service providers

Over 90% of the world’s water supply is under public control, mostly municipal or provincial in ownership. Historically, water and sanitation services were developed by both the public and private sectors. In the last century however, there was a tendency for governments to take over these services, for social and financial reasons. The clock is […]

Power Supply Shortages

Power supply shortages are nothing new, and regular occur following extreme weather incidents affecting infrastructure, unexpected increases in power demand such as demand for air conditioning on a very hot summers day and failure of generators, transformers etc. As a result of a lack of power supply following the 2011 earthquake and tsunami in Japan, […]
