"In a world where almost everything is run by machines it not surprising that we are also running out of energy sources what worsens the case is that the energy sources that we use are destroying the world we are living in. Another dilemma people are now facing is these energy sources are bound to vanish years from now. The potential of renewable sources is massive as they are expected to meet world's energy demand. Renewable energy sources are biomass, hydropower, geothermal, solar, wind and marine energies they can provide sustainable energy services, based on the use of routinely available, indigenous resources. The renewable resources such as biomass, wind, solar, hydropower, and geothermal can provide sustainable energy services, based on the use of routinely available, indigenous resources are attractive renewable fuel in utility boilers."

The heavily forested city of Ketchikan, Alaska, is built on rock and surrounded by water. Every commodity that comes into Ketchikan must arrive by sea or air. The use of fuel oil is problematic for both economic and environmental reasons because the oil must be obtained and refined elsewhere and transported (using additional fuel). What's more, fuel oil is subject to price instability. Southeast Alaska Discovery Center in Ketchikan, which provides information to more than a million visitors each year, is the site of a pilot biomass boiler system now coming to life. Two oil-fired boilers serving the 250,000-sq-ft center were replaced with a highly efficient system fueled by local wood. Manufactured by Hurst Boiler & Welding Company Inc., the hot-water boiler was custom-designed to fit within very limited indoor space.

Wine, spirits, meat and even baby food can all be faked, with fraudsters hiding their true origins. Now forensic scientists are clamping down on food fraud, which costs millions in lost revenue and can put the health and safety of the public at risk.


Imagine tucking into a fine fillet of "British" beef, only to learn it actually came from Australia. Or drinking "French" wine that actually came from California.
What if the "Italian" olive oil you pour over the accompanying salad originated in Morocco?
That might not be so bad, you may think.
But what if a bottle of vodka you'd purchased in good faith is tainted with methanol, making it lethal to drink?
Or the baby food you feed your youngest is not what the label on the jar said it is?
As global trade has increased, so has the potential for food fraud, where fraudsters lie or hide the true provenance of produce.
Alongside food safety and health fears, its raises concerns over quality control, reputational damage and lost revenue, and puts the spotlight on illegal activity.
Now some firms are taking to using scientists, a type of food "crime scene investigators", to tackle the issue.
Faking it
In a world where food is exported and imported every day, how do you prove that the origin of a product is legitimate?
A company in New Zealand has developed a scientific origin system which maps and catalogues "food fingerprints".
"What we do needs to be able to stand up in court," says Dr Helen Darling, from Oritain.
Most food supply chains use predominantly paper-based systems to trace the origin of food, such as following barcodes.
But while these show the route a product has travelled and how, and "whatever kind of details you want to capture in that system", says Dr Darling, Oritain's proof of origin "cannot be faked".
Oritain's scientific liaison officer Rebecca McLeod says it ties food and drinks back to their geographic origin, by mea
