Tech gets energy efficient

'Information and communications technologies' (ICT) use energy as well as helping to save it - more energy-efficient ICT could help make further savings and reduce CO2 emissions. An EU-funded project has developed a plug-in ...

New solar-cell design based on dots and wires

Using exotic particles called quantum dots as the basis for a photovoltaic cell is not a new idea, but attempts to make such devices have not yet achieved sufficiently high efficiency in converting sunlight to power. A new ...

Squashed loft insulation 50 percent less effective

Research from the National Physical Laboratory (NPL) has shown that by squashing down loft insulation, for example under storage boxes, homeowners almost halve its performance.

Monitoring manufacturing processes to optimize energy consumption

Saving energy is becoming ever more important for manufacturing companies. One prerequisite is to capture the machines' energy consumption for each step in the production process. This can be achieved with a monitoring system ...
