CSP industry should turn to biomimicry says MIT researchers

A team of researchers have discovered that if the mirrors or heliostats of a concentrating solar power (CSP) tower plant are arranged in a sunflower-inspired pattern, the efficiency of the solar field can be boosted.

CSP tower plants such as PS10 in southern Spain comprise a 100-metre high pillar surrounded by rows of giant mirrors rippling outward. More than 600 of these mirrors, each the size of half a tennis court, track the sun throughout the day, concentrating its rays…

Cost concerns putting companies off energy efficiency

The vast majority of companies have invested in basic energy efficiency measures but are being put off making larger investments because of high capital costs and fears over the length of time it will take to see returns.

That is the conclusion of a survey of more than 250 businesses leaders commissioned by Ernst & Young, which shows that while over 70 per cent of those polled had made basic improvements to temperature controls or lighting, just 12 per cent…

How to Make Your Home More Energy Efficient

Appliances are evolving all the time. While you might think that your 25-year-old refrigerator is saving you money as long as it’s in working condition, the opposite is actually true. Thanks to recent improvements in compressors and insulation, newer refrigerators use much less energy than those from even just 10 years ago, according to the experts at Nason’s Appliances.

For example, a new Energy Star refrigerator will save over $100 if you replace one purchased in the 80s or almost…
