Millions of hectares of contiguous equatorial wasteland will soon produce a crop that offers solutions where other biofuels face questions. Drake Calvin reports.
Wind farms are normally associated with mountainous areas and remote regions. But how about one planted in a city on the site of an old steel mill? Drew Robb reports.
Scientists are researching new ways of harnessing the sun’s rays that could eventually make it cheaper for people to use solar energy to power their homes.
Deep in a disused gas well, German scientists are conducting hydraulic fracturing experiments in order to provide geothermal energy both for heating and to power an electricity generating plant. Sean Ottewell reports.
With current global demand for energy exceeding the world’s crude production capacity, causing oil prices to soar, wind power is becoming an increasingly viable industry.
Irish minister for communications, marine and natural resources Noel Dempsey has set a target to treble the contribution made by renewable energy from 5percent to 15percent of electricity produced by 2010.
A partnership of UK companies, Imass and Econnect, has been awarded a grant of £90 000 by the Department of Trade and Industry under its Collaborative Research and Development Technology Programme to continue their work in the Renewable Energy sector.
Geothermal power generating plants, which make use of the planet’s interior heat, are becoming increasingly popular around the world. Research is still being carried out into the most efficient way to extract the heat but commercial plants are already in operation.
The world’s largest solar power system – located in Bavaria, Germany – is exceeding performance expectations since the solar photovoltaic array went live over a year ago.
The dramatic spike in heating oil, gasoline, and natural gas prices is bringing to the forefront the need for alternative, renewable energy sources such as solar technology.
With most of an estimated £130 million of global capital investment earmarked for UK activity, a new report prepared for the Scottish Enterprise Energy Team says a diverse range of Scottish sectors are well placed to capture work in marine renewables projects.
When a new technology grows as fast as wind energy has done over the last few decades, conventional parts and solutions often no longer fit. Siemens Wind Power is one of the major wind turbine manufacturers that have helped develop wind-power technology.
US Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials than previously thought.
The Siemens Power Generation Group (PG) is to build a turnkey biomass-fired power plant in a consortium with Kvaerner Power.
LMain gearboxes in wind turbines can exhibit the phenomenon of torque inversion; where the load transfer in rolling bearings changes and leads to a displacement of the shafts relative to each other. These relative movements become bigger with increasing elasticity of the whole construction and with increasing bearing clearance.
