"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. Under the direction of E. Dane Ash, project manager for Tyonek-Alcan Pacific LLC, the biomass boiler system was developed with Hurst representative Gregory W. Smith of Global Energy Solutions Inc. to address environmental concerns, as well as issues related to building space, fuel costs, comfort, reliability, and simplicity of operation. The new boiler is located on the lower level of the Discovery Center, which requires heating for a minimum of nine months a year. Local wood densified into fuel pucks is delivered to an elevated walking-floor storage bin in a vestibule area built to protect against excessive moisture. (The biomass-fired boiler can burn any wood product with up to 50-percent moisture content.) An auger moves pucks from the storage area to a metering bin and into the boiler. Freezing is not an issue because the walking floor easily breaks up any frozen contents. The boiler system was designed to highlight how biomass can reduce or eliminate the use of fossil fuels. Visitors can see the boiler operate through specially designed windows. In the hall just outside of the boiler room, the noise level and ambient temperature is consistent w

" There are five basic categories of material of biomass such as: *Virgin wood- from forestry, arboriculture activities or from wood processing. *Energy crops- high yield crops grown specifically for energy applications *Agricultural residues- residues from agriculture harvesting or processing * Food waste- from food and drink manufacture, preparation and processing, and post-consumer waste *Industrial waste and co-products- from manufacturing and industrial processes. The question is how are we going to use this biomass as a fuel for boilers? But what is a boiler in the first place? A boiler is defined as "a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is superheated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy." Let us then go back to the previous question, how are we going to use this biomass as fuel for boilers. Nowadays, the prime sources of energy in the world are oil, coaland natural gas. But these natural sources of energy has their end too, unfortunately it is already anticipated that within the next 40-50 years these sources of energy will deplete. Worst is, it is also expected that from these sources lies consequences due to their emissions such as global warming, acid rain, urban smog. Due to this fact the world is trying to utilize new sources of energy, there are some renewable energy sources that can replace harmful energy sources. The solar, wind, biomass etc are energy sources which are less harmful to the environment but can only be use in a suitable way. Biomass is one of the earliest ever discovered sources of energy but only comes with specific properties. It was then discovered that utilizing biomass in boilers offers many economical, social and environmental benefits such as financial net saving, conservation of fossil fuel resources, jo

"The Commission The Commission by environmental campaigners forecast 3 trillion euros would generate by 2050 on their green revolution campaign- to make EU energy almost totally carbon free. Read more With emerging renewable energy alternatives today, it is highly important that they be given enough attention even early on their developmental stages. Such technologies might not be ready for commercial uses yet but their potential should be amply tested and funded. Society's modern lifestyle is in serious need of energy that can be generated and consumed and yet, not compromise the future state for generations to come; to have no anxiety that it would cause damage to the environment. The energy shift The energy shift would already create around half a million extra jobs by 2020, Crown researchersfrom German aerospace center DLR, which also specializes in energy and transport, found. It has legislated to ensure that 20 percent of the energy mix is green by the said year, as part of a set of three main environmental goals. But it has yet to achieve agreement on binding targets beyond 2020, even though non-binding roadmaps have laid out the need for a virtually carbon-free electricity mix by 2050. Commissioned by Greenpeace and the European Renewable Energy Council (EREC), the 2012 Energy evolution report lays out risk avoidance towards almost carbon-free energy. They include curbing energy demand through greater efficiency, increasing investment in wind and solar power and phasing out subsidies for carbon-intensive energy, such as coal. To bring about the energy transformation, it sees a need to invest about 99 billion euros between now and 2050 or else this will be added on the list of renewable energy scam, but it says the financial gains are much greater. Renewable energy has no fuel costs; the fuel cost savings in the energy evolution scenario reach a total of 3, 010 billion euros up to 2050, or 75 billion per year. Another benefit is job-creation, one of the
