Nowadays there is a LED revolution in the lighting segment. In terms of energy efficiency LED luminaires are the most promising, as they can significantly reduce the energy costs, have high luminous efficiency and longer service life as compared to traditional light sources.
Geli Keeps the Lights On When Utilities Can’t - Case Study
Challenge Imagine you’ve found the perfect plot of land and construction has started on your dream home, but in order to turn the lights on it will cost an additional $250,000. That’s exactly what happened to one couple in Marin county in Northern California. When local utility Pacific Gas & Electric quoted an exorbitant price to extend grid power to their new home, the owners decided to generate their own electricity. Solar alone could not provide for all of the home’s needs, especially...
Shining a Light on the Food and Beverage Industry
As published in this months edition of Process & Control, Diane White discusses how UV systems can provide a practical, power saving alternative to pasteurisation in food and beverage production Waterborne micro-organisms are responsible for adverse effects on flavour, colour, odour and shelf life of products and, of course, potential health risks to consumers. A number of emerging pathogens, like Cryptosporidium and Giardia are highly resistant to conventional chemical disinfection. As a result, the food...
How to choose the most cost-effective methods for improving water quality
Agricultural run-off can contain pesticides, sediment particles and nitrates and is a major threat to the health of the sea. Although there are policy frameworks to reduce run-off water, they often don’t clearly explain how to maximise benefits. A new study provides an economic framework that prioritises methods based on their cost-effectiveness, which could help policymakers to reduce the pollution of marine ecosystems. Agricultural run-off can contain pesticides, sediment particles and nitrates, and is a...
Lighting the way for disinfection - Case study
Pharmaceuticals manufacturing involves the handling of powders and volatile, flammable solvents such as iso-propanol. Consequently there is every opportunity for explosive atmospheres to form. Where this is the case, the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) require that new equipment and protective systems must be selected on the basis of the requirements set out in the EU ATEX Directive (Directive 94/9/EC) and enshrined in the Equipment and Protective Systems for Use in Potential...
What are the true costs of rising sea levels?
A simple relationship between sea level rise and the massive potential costs of future coastal flooding has been established by scientists in Germany. As sea levels rise, thedamage to human economies rises even faster.And as sea levels rose by an estimated 14cms in the last century, and could rise by up to 130cms in this century, the coastal cities of the world could face huge bills for storm and flood damage, or for investment in coastal defences. Either way, global warming and attendant sea level rise −...
