Ocean Energy 2005

Ocean Energy 2005 – from the NRG Expert Historical Energy Data Series Ocean energy is mostly in an experimental stage. Many ideas have been generated and a lot of experimental projects are being funded both by governments and commercially. These range from technologies and schemes which produce small amounts of energy for local, often dedicated […]

Renewable Energy Challenges

Renewable energy sources present particular challenges for the electricity grid. For example, the performance of hydro plants is diminished in dry seasons; good wind conditions don’t generally correlate to when electricity demand is at its highest; and, of course, solar power generating technologies depend on clear sunshine. While weather prediction technologies are improving, they are […]

Water Deregulation Report 2008

Water Deregulation Report 2008 – Historical NRG Expert Energy Data Series Although the absolute figure looks large, the water and waste sector lags sadly behind other the infrastructure sectors in the private investment it receives. By the end of 2006 526 PSP projects worth a cumulative total of $53 billion had been closed in the […]

Nuclear Power from the NRG Expert Data History Series 2009

In 1965, ten years after Britain commissioned the world’s first commercial nuclear power station at Calder Hall in 1956, global consumption of nuclear energy reached six million tonnes oil equivalent (Mtoe), amounting to 0.15% of the world’s total energy consumption from all sources. This rose steadily to 637 Mtoe in 2005, 6.0% of total consumption. […]

Gas Deregulation Report Global 2002 From the NRG Expert Historical Data Series

The gas sector differs from the electricity sector in that not every country produces or uses gas, natural or manufactured, whereas every country generates and uses electricity. The transport of natural gas requires enormous investment with pipelines covering great distances, sometimes thousands of kilometers, or conversion plants and shipping for liquified natural gas (LNG). 21.7% […]

Solar PV 2009

Solar PV 2009 – Historical Data Seies. Global investment in renewables grew very fast from $35 billion in 2004 to $148 billion in 2007, averaging over 60% growth a year, but slowed down with only 5% growth in 2008 to $155 billion. $41.3 billion was by company investment through VC/PE (venture capital/private equity), equity in […]

Mechanical Storage

There is increasing discussion of linking wind power systems with pumped storage hydro facilities, especially in Norway and Canada, directly via the grid. This was effectively done with Danish wind power, a large amount of which has been generated at periods of low demand, necessitating export to Norway and Sweden. Pumped hydro storage alone will […]

Historical Analysis – Coal Industry in Poland

Poland has steadfastly pursued a policy of economic liberalisation since 1990 and today stands out as a success story among transition economies. Even so, much remains to be done, especially in bringing down the unemployment rate, which is still the highest in the EU despite recent improvement. The privatisation of small- and medium-sized state-owned companies […]
