If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot. So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels? What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas. This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive. Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming. Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems. These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel. Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field. Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons. Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities. Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets. Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.

Gasification Sees a New Dawn and How it Will Benefit Us All
Always Rely on Professionals Proper Installation of Wind Turbines is Very Important
Always Rely on Professionals Proper Installation of Wind Turbines is Very Important
The most efficient and economical way of using wind power to light up your home is to install a windmill or wind turbine as they are also called. The current trend is to use green energy to supplement energy generated from fossil fuels to ensure uninterrupted supply and protection of the environment.
Wind turbines of different sizes are available for your different requirements. If you live in an area where the average wind speed ranges around 10 to 12 miles per hour, you can install a wind turbine to generate electricity throughout the year. Depending on your energy requirements, you can opt for the right sized wind turbine starting from 2Kw units to even 20 Kw units.
Choosing a wind turbine manufactured by a reputed maker is essential but your task does not end there. You should choose the right contractors for installation of the wind turbine. Proper installation of wind turbines is very essential because of the following reasons.
• Installation of a 42 feet or more structure is not a simple task. The installation must be perfect to ensure that there are no safety concerns. Even the smallest flaw in installation can have severe consequences.
• A wind turbine may look like nothing more than a fan attached to a long pole. However, it is a complex and delicate mechanism that can be damaged with careless handling and improper installation. This can render your entire investment totally waste.
• The fans of the wind turbine may seem to be revolving very slowly from ground level. However, the height and the weight of the fans combined with its velocity can cause a lot of damage if breakage or other malfunction occurs.
• It is common to make use of the land beneath a windmill for other purposes. If you ensure that the wind turbine is safely installed, you can set up structures under the wind turbine without any fear of accidents and injuries.
• Setting up a wind turbine for your home will ensure that your energy requirements are taken care of forever. However, this requires a high initial investment. Improper installation will mean that your entire investment goes waste without sufficient benefits. What is the point of sinking thousands of dollars into your windmill if it conks off within a few days and you have to spend more repairing a faulty installation?
Hence, you should always deal with professional wind turbine contractors who know what they are doing. How to identify reliable contractors from all those who claim to be the best? For starters, all professional contractors who take up such projects of green energy offer a free quote. They do not charge for a quote which helps you estimate the cost of the project. Rather, they would be more than happy to offer the quotes for free.
Another way to identify professional service providers is to take a look at the spares and materials they use. Professional wind turbine installers will never use counterfeit material to reduce cost.
They follow strict safety codes and comply with all professional standards at all times. The net result of dealing with such installers for your green energy requirements is that you are assured of the best service at all times.

Green and Clean Computing
Little thought may be given to the energy consumption of computers, but as more and more computers are purchased each year, it is not just the number of computers that forces increased energy consumption but the way in which computers are being used that adds to the building energy burden. Research has shown that most computer desktops are not being used a great deal of the time they are running and are left on for long periods of time. As with other forms of energy consumption, electricity is wasted when it is not being used and this burns fossil fuels that emit carbon dioxide into the air and cause smog, acid rain and other detrimental environmental side effects.
The typical desktop computer consists of a system unit which houses the central processing unit (CPU), a monitor and a printer. The CPU may require 100 watts of electrical power; the monitor, which may be 15 to 17 inches, may require another 50-100 watts; a laser printer can use as much as 100 watts or more while ink printers use as little as 12 watts while printing. The cost for operating a 200 watt system all day and night, everyday, would be $125 annually, while the cost of operation for normal business hours of 40 hours per week would range around $30 annually. Considering the tremendous benefits derived from using computers, this figure may not appear extensive, but when multiplied by the many computers used on a daily basis in this country, the total grows phenomenally.
There are many ways to reduce personal computer energy consumption. Computers, printers and monitors can be turned off when not in use. Many years ago, it was considered harmful to the computer if it were turned on and off periodically during the course of a day. However, the internal circuitry of personal computers is designed to be protected from power damages that might result from on and off switching. Doing so will not substantially affect the computer’s useful life.
The use of screen savers wastes energy and should not be used. They go back to the days when, if not used, images would be ingrained on screens if they remained on too long, but updates in technology have long made the use of screen savers unnecessary.
The United States Environmental Protection Agency has also developed technology for computers and monitors that can be programmed to automatically power down to a lower power state when not in use. This “sleep mode” can reduce energy consumption by 60% to 70% and these “Energy Star” computers serve to gain efficiency without any loss in computing performance.
Green computing extends beyond the personal computer to the use of related devices and materials. For example, paper waste can be reduced by printing as little as possible and only when necessary, recycling waster paper, using electronic mail instead of faxing to eliminate the need to produce a hard copy, and trying to print on both sides of the page when possible. In addition, printer and toner cartridges can be recycled. Although this is a practice that has been discouraged in the past by printer and toner cartridge manufacturers, such recycled cartridges save resources and reduce pollution and solid waste. Disposing of electronics as well can be done through recycling agencies to reduce waste and provide for recycling of functional equipment.
Finally, green computing also means not buying new equipment unless there is a real need for it. Close investigations can be made regarding upgrading hardware or software before purchasing a new computer. However, if the determination is made that a new computer system should be purchased, there are “Energy Star” computers, monitors and printers on the market. In addition, ink jet printers use 80% to 90% less energy than laser printers and soon, even “Green Computers” will reach the marketplace for sale.

Have You Got Earthday Business
Have You Got Earthday Business
The sun is shining across the hills of West Cork as I listen to the story of Earthday told by a team of evangelists with nothing but Earthday business on their minds. In 2008, visionary Simon Ford started a group to bring like-minded, positive people together in socially conscious activities. He called the group Social Traffic and right now that group has Earthday business on its mind.
The group’s first major campaign centers around Earth Day with an event named, Earthday Birthday a global birthday party for Mother Earth. Earthday 2009 and the celebrations that will go with it is all set to clamor its way across the social media landscape like some all embracing vine, covering the sometimes harsh elements of the online world with a softer, greener facade which many hope will last for more than a lifetime.
Earthday 2009 is a global celebration and a day to spread awareness of people’s destructive impact on the planet. But before you jump right in there and start changing the world on a massive scale here’s a few simple things you can do to make a difference right now, tomorrow and every single day after that.
Here’s my list of top five things to do to celebrate Earthday 2009 and reduce your impact on our planet;
1. Plant a tree or two. If you’re feeling energetic plant a whole field full.
A tree will absorb CO2 and other forms of pollution, provide a home to hundreds of creatures, help to create and retain soil and performs a whole host of other ecological functions. And, in case you needed a reminder, will leave a lasting legacy of your time on the planet.
2. Walk to work for a day, a week or a whole month. You’ll feel better and the earth will be a much healthier place to live too.
You might even want to think about joining a car sharing scheme and make it a permanent part of your work life balance to drive to work only one day a week and sleep the other four in the passenger seat while someone else does all the hard work!
3. Dry your dishes naturally. Turn off the dishwasher at the dryer stage of the cycle and leave your plates and cutlery to dry themselves for a change!
4. Turn off all your plug sockets before bed. Maybe spend the evening in the dark for one day a week and treat the kids to a few ghost stories before bedtime!
5. Don’t be a water importer.
Get rid of your supply of bottled water, keep a jug of fresh tap water in the fridge and reduce the damage we do to the environment by producing plastic bottles to hold gallons of mineral water that tastes no different to the clear, fresh water that is piped through your home.
So, if you’ve got business on your mind this Earthday, perhaps you should take a few minutes to look around you and realise how precious our planet is and how beautiful that small piece of turf is right outside your window.
If you want to know more about this subject and how you can make a difference take a look at this great squidoo lens all about Earth Day Birthday right now.
Neil Ashworth is a member of Simon Ford’s Social Traffic Team who are raising awareness of environmental issues using the power of social media marketing to support the Earth Day Birthday campaign.
