Welcome to Climate & Our Changing World - The way our changing climate is affecting billions
Alternative energy is a term which is passed around when discussing alternatives to fossil fuels and try to reduce the effects of climate change and global warming. By now everyone is aware of the fact that our consumption of fossil fuels is not only unsustainable, it also affects our planets climate. Fossil fuels are effectively a large store of carbon deep underground which is made up of plants and animals from thousands and millions of years ago. When we use and particularly when we burn fossil fuels we are re-introducing this carbon into the current carbon cycle. The current carbon cycle is in balance between what plant matter absorbs and the gases released during the combustion and decay of recently dead plant mater. By during fossil fuels we are introducing additional carbon dioxide into the cycle, which cannot be supported. This means excess carbon sits in the atmosphere and acts like a mirror reflecting the suns energy back at the earth and increasing global temperatures. Alternative energy is anything other than current forms of used energy, hence fossil fuels. Biomass is a form of alternative energy and needs to be better utilized in our energy future.

Biomass is plant matter that can be used as a fuel source in either solid, liquid or gas form. This includes purpose grown fuel sources but also residual resources and waste resources. The most common and well known form of biomass is wood. Wood fuel sources no longer simply refer to felling large trees to make into logs. A lot of it refers to growing specific wood species for fuel production due to their high yields and then converting the wood in to a useable energy form. One of the simplest, low energy input ways to turn biomass resources including wood into a fuel source is to upgrade the resources into pellets. You maybe familiar with wood pellet stoves, which can automatically feed them selves with pellets to heat rooms or whole properties.

Pellet machines, which are also referred to as pellet presses or pellet mills are used to compress the raw biomass material into pellets. First the raw material is reduced to a small uniform size with low consistent low moisture content. To manufacture constituent quality pellets is with a consistent quality raw material. The raw material then enters the pellet machine and is heated and under pressure is reformed into wood pellets.

For an energy source to renewable it must be possible to replace it with its lifetime of use.. Fossil fuel energy is not a form of renewable energy as our consumption far outweighs the replacement of fossil fuels. Several types of renewable energy exist, these include solar, wind, wave, geothermal and biomass. All of these energy forms are necessary in our energy future, however biomass offers several other benefits. As biomass is a tangible resource it fits in well with the market economy and trading. More jobs and income can be generated in biomass than the other renewable energy forms as jobs and income can be generated in the growing, upgrading into a usualbe form of energy and supplying it to the customer.
Learn more about Renewable Energy Source Pellets
Pellets are a common type of renewable energy, and a good example of how a biomass energy economy can be established. Jobs and income can be generated on the production of the wood raw material, the processing of the wood into pellets and the distribution of the pellets to the end customer. Wood pellets as a renewable fuel source burn very cleanly producing very little smoke and ash. The low ash percentage also helps to keep manual maintenance to a minimum, much lower than burning wood logs for example. Also because of the uniform shape and size of the pellets, pellet stores can on demand place more pellets in the fire.

Pellet presses, pellet mills or pellet machines are used to compress the raw wood material into pellets. To do this the raw material must be reduced to a uniform size through a hammer mill to a smaller diameter to the hole in the pellet press die. The raw material must also be fairly dry before entering the pellet mill. To form a pellet sufficient pressure and heat are required to melt the wood and then the pellet press forms the melted wood into a pellet. When the pellets come from the pellet press they are very hot and still quite soft, and only become hard once they cool down. Once the pellets have been cooled before they are used they must be kept away from moisture. If pellets are exposed to moisture they will absorb it, once the pellets absorb too much water they can no longer be used for fuel.

There is a clear need to source alternative fuels to current fossil fuel options and these include pellets. Pellets for fuel purposes can be made from a large selection of resources. Wood is such a resource; wood residue is available as a waste resource from sawmills. Sawmill waste is usually sent to be made into premium wood pellets as it contains very little or no bark and is predominately pine, spruce or oak residue which produces very little ash during combustion. Premium wood pellets also contain very little moisture, which also enables a higher combustion temperature and more complete combustion. Many other biomass resources can be processed into pellets to be used as fuel. These include purpose grown energy crops such as miscanthus, switchgrass and hemp. Other resources such as grasses and straws can also be produced into pellets. Burning other biomass pellets as apposed to wood does however create issues. These issues include higher ash content, possible clinker and slag formations and corrosion issues.

Wood pellet stoves are more suitable for heating small spaces to provide either your full or supplementary heating requirements. Wood pellet stoves come in various different shapes and sizes, with various heat outputs. Pellet burning is also quite beautiful and a nice focal point. Some pellet stoves come with an additional back boiler to connect up to your central heating system. It is possible to use other fuel pellets in pellet stoves, however the burn pot design and several other features are crucial to whether the stove can burn the pellets efficiently and without damaging the stove.

Wood pellet boilers are required for properties that have a lot more space and the heating power exceeds 10KW’s. Some people choose to have a small pellet stove in the living room and then use a pellet boiler to heat the rest of the property. Running a pellet boiler is a lot less work than running a log boiler for example. Pellet hoppers can come in a range of sizes from holding a day or so of pellets to holding up to a years supply. Depending on the type of fuel used in the pellet boiler the amount of manual maintenance will change, for example the ash content. Straw fuel pellets for example can contain over 10 times the ash content of say premium wood pellets.

“The illnesses don’t strike us out of the blue, they develop from everyday small sins against nature. If these pile up every day, they burst out apparently all at once.”
Hippokrates - 460 - 377 v.Chr.
Already every fourth child suffers from allergic illnesses, like Neurodermitis, hay fever or asthma attacks. The children differentiate themselves strongly from their unnatural environment, that has been confirmed trough the drawings that they paint. Especially big-city children experience the world in which they live, often as foreign and menacing. Many children already grow up with the consciousness of the destruction. I can tell you more and more about the connections between Children and our Planet Problems here. We adults must learn not to go the way of the slightest opposition any more. We cannot expect that the children repair what we have destroyed. The first step would be to reduce the limit values with pollutant measurements.
However, the responsible politicians hear on the ecological ear especially hard. That’s why the organization also exerts itself to bring to life an international children’s rights organization which works as Amnesty international and should take care of the fact that, also the ecological child right is understood as a human right. We must understand Why Go Green Now fast !!!

Building biology and Building Ecology is the Answer of the comprehensive relations between living being and residential environment.
The main focus lies here on comprehensively in terms of extensively or integral.
Comprehensively is the expression of creative principle of the perfection, maturity and freedom.
All areas of the biology (living being) and the construction (residential environment) under the guidance of the logo (biology) interlock here.
Construction biology belongs to the biological-culturally oriented departments; it is no narrow special field, rather it is specialised covering.
Only under a such mental superstructure are People and culture able to stand in the centre of the construction and settle, not prestige, party policy or other interests.
If the biological principle is absent to the satisfaction of the elementary requirement of accommodation of the people, construction culture and architecture perish, the construction events become banal,soulles,inhumanly,irresponsibly.The existing relations in which the people atrophies mental-spiritual-physical and will be ill, confirm this much too clearly.
The Greek syllables logos, Arch (beginning) and Ur are relatedly to each other, in this respect also biology, architecture and culture, the origin and the unity of the reside, the creative principle are expressed in it. In this sense the architect is an originator or ur creator.
„ Also to us architects the strength to the constructions and the courage to the freedom comes
only from the connection and the quiet devotion to this ur order of the people,
beause of love to the creation constructive person “.

Most of our current energy and electrical production either comes from coal, oil or nuclear power plants. While coal and oil power plants are prime culprits for high CO2 outputs linked to global warming, nuclear power plants are hardly the safe or cheap option. So what other energy options to produce electricity are available to us, and should we follow the same network set-up of a few large-scale electrical production facilities. Wind and solar power gain most of the headlines in the papers on how to generate green electricity. There are also solar thermal power stations where the suns energy is directed by a series of large mirrors to a tower with a boiler at the top. The heat from the sun is directed onto the boiler. The boiler then produces steam, which powers a turbine to produce electricity, which is sent back to the grid. Is it also possible to produce electricity from wood and other biomass resources, even on a small scale. Wood and biomass when combusted efficiently are a carbon neutral fuel, which burns much cleaner than oil and particularly coal.

Pyrolasis can turn resources such as wood residue, straw, grasses and any other form of biomass and waste into a collection of gases. These gases include methane, carbon monoxide and hydrogen; with a 1:1 air ratio in a combustion engine the gases can run any internal combustion engine. So even a small setup could be used to run a gasifier on wood or any other biomass and then put the electricity into your home or send it into the grid in return for revenue.. There are several advantages from completing this process on a small scale which include control of your energy cost and supply and additional revenue from selling energy back to the grid. Energy will only become more expensive in the future, generating electricity on a small scale can produce cheaper energy and at the same time generate long term jobs.

Large gasifiers can operate on most forms of biomass, and can do so economically and efficiently because of the expensive automated setup. Obviously to keep costs of operation and labour to a minimum automation is also important however the cost of the equipment to justify output must also be considered. To enable an efficient process with low costs on a small scale the best option is to upgrade the raw material into pellets. Pellets have a uniform shape and size and high density, therefore contain very high yields of energy per tonne of fuel compared to unprocessed biomass. By operating a small scale gasifier on pellets provides the level of automation required to produce electricity on a small scale with low costs and reasonable income.

Burning wood pellets and other biomass fuel pellets efficiently depends on several factors including volume; speed and temperature of combustion air and burn pot designs. Pellet stoves and boilers come in all different sizes and heat outputs, ranging from the simple designs to cope with premium wood pellets, to more sophisticated designs, which can cope with high ash content pellets, clinker and slag formations and corrosion issues. Pellets burner much cleaner than logs or coal producing less smoke and particulates. Due to this pellet combustion produces much less ash and therefore much less maintenance than burning other fuels. There are other areas of pellet combustion that are attracting interest in both the developed and developing world. In the developed world, pellet BBQ’s are growing in popularity. Both softwoods and hardwoods are being produced from varieties such as apple and cherry wood and the flavours transfer very nicely into the food. Using pellets of these wood varieties also means pellet BBQ’s are also ideal to smoke food. For countries such as Africa and India, using pellets for cooking fuel is getting a lot of interest.

Basic stove designs using solid combustion technology are being designed so people can use a wide variety of local biomass resources to produce fuel for cooking purposes. Deforestation is becoming an even more serious issue; due to western activities of removing forests there is less wood resources for local people to use in a sustainable way. With open fires most of the energy is lost and combustion efficiency is very poor. So to reduce the deforestation, more resources must be made available in a useable form and combustion efficiency must also be dramatically increased. Basic stove designs such as the rocket stove work on the principles of gasification and complete combustion. This means the stove is far more efficient than an open fire, cooks the food far more quickly and also more importantly uses far less fuel. These stoves require no power supply to operate and also very reliable, which is important to try and speed up improved combustion technology adoption.

Pellets provide a means to use a far wider range of potential fuel sources other than wood. Agriculture is obviously the main source of income, and there are huge resources wasted after the food crops have been harvested. Straw is regarded as a waste in many countries and simply burned in an open fire. This is not only really bad for global warming due to the poor combustion, however it is also a massive waste of useable energy. Straw can be turned into pellets, which is ideal for these designs of stoves.

From the operators of www.iBuyLessGas.com–dedicated to improving MPG with Ethos FR+ Fuel Saver.
As the cost of living continues to rise, energy reports and broadcasts are packed with energy saving tips and suggestions. Some energy saving tips call for initial investments, some just solicit a change of lifestyle. The best energy saving tips are those that require almost nothing but changing a practice. This one is about the wise energy saving choices.
1.Limit, as much as possible, the consumption of water. Of course water is not that pricey (at least for now); but saving water saves energy. When cleaning the driveway, the deck or patio, using the broom instead of the hose would save several hundreds of gallons of water a year.
2.A push lawn mower is a good idea for mowing a small lawn. Aside from not using electricity or fuel to ride the mowing machine, it is also good exercise.
3.Rakes are first-rate leaf movers. Like the push mower, you do not need energy to fuel up a machine to get the job done. There is also a sense of nostalgia in using this traditional tool.
4.Use compact fluorescent light bulbs to light your driveway or as a security light. CFLs are one of the most handy and energy efficient products that you can have. If you are troubled about bugs sticking to the light, there are yellow CFLs that are available.
5.When shopping, steer clear of going for the disposable items. Disposable products need more landfills and landfills emit dangerous gasses. Go instead for items that could be used several times over. Again when shopping, go for products that are made of better quality. They might be a little more pricey but generally, quality products last longer.
6.Bring your own bags when shopping. Paper bags are made from trees; the environment can use more of them. Plastic bags on the contrary are oil based and are not biodegradable. If you bring your bag with you, you do not only aid in saving energy, you could also get a discount from your store.
7.Batteries contain toxic materials. They produce heavy metal like zinc, zinc, arsenic, cadmium, mercury etc. Thus, disposal needs proper care. Once the heavy metal in batteries seeped into the ground it has a good chance of contaminating the ground. When buying products that would need batteries, pick those that are rechargeable. That way battery disposal is limited and you save on the cost of buying new batteries.
8.Good thing that SUV sales everywhere are going down (well, at least for the environment and not for car manufacturers). SUVs use much more energy than compact cars for the same distance. While using SUV’s could be fun, there is also that tinge of lack of sympathy to the current energy issues and environmental problems we are facing. Reducing the use of SUVs on the street may not mean much in terms greenhouse gas emissions but is a signal to manufacturers to build more energy efficient vehicles.
9.The use of solar power is an excellent idea if you want to tackle the issues of energy conservation and environment protection. If there is one thing that the world needs most at this time, it is the widespread use of solar power.
10.Energy saving devices may cost a little extra but the pays offs are much more than the extra cost in terms longer life spans and energy saved.

Today around the world the interest in pellets is growing. One of the largest industries currently for pellets is the animal feed industry. Animal feed formulas are prepared, then through heat and pressure in a pellet mill reformed into pellets. Animal feed pellets store better than loose animal feed and also take up much less storage space, it is also easier to ration out set amounts of feed. These advantages are what have developed the feed pellet industry in the size it is today. As oil and gas prices continue to rise, pellets are now being taken seriously as a high efficiency fuel. Many different possible organic fuel sources can be compressed into pellets. Currently the most popular form of fuel pellet is the wood pellet or more specifically the premium wood pellet. Wood in pellet form is a very efficient burning fuel. Due to the high density of the wood in pellet form, a much higher heat value and less ash and particulates are produced compared to burning wood logs for example. Other possible organic fuel sources which can be processed into fuel pellet include straw, miscanthus and hemp. A lot of waste streams could also be pressed into fuel pellets, these include agricultural residues and even cardboard.

Burning wood pellets is relatively straightforward; they produce very little ash and have no significant issues with corrosion. Therefore they also require very little maintenance with some pellet stoves and boilers operating for several months at a time unattended. Other biomass fuel pellets are not as easy or as simple to burn as wood pellets. These issues relate too much higher ash contents, possible clinker and slag formations and corrosion issues. Sulphur and chloride are contained within some organic fuels are highly corrosive elements. Coal for example contains high levels of Sulphur, burning corrosive fuels in burners not designed to cope with the fuel can quickly corrode the burner. BBQ wood pellets are also growing in popularity over gas BBQ’s, using hard and softwood pellets for cooking can make some of the best BBQ food available.

All pellets are produced with the same equiptment with the a few basic changed in the setup. Firstly the raw material needs to have relatively low moisture content, and particle size also needs to be fairly small. A pellet mill is then used to reform the material into pellets of various diameters. In the pellet machine there is a roller and a die, as heat and pressure increase the raw material is compressed through the die into pellets. As the pellets come from the machine they are very hot, and they must be cooled before they turn hard. Fines must be separated from the pellets before they can be bagged and stored.

In today’s ever-changing planet of polluting acts and contaminating habitats, most of us believe that only one man has what it takes to pull us onto a track of recovery toward a Green and energy efficient society. That man is the current U.S. president, Barack Obama.The U.S. is a powerful country that affects many other countries around the world, so having someone like Barrack Obama in office is great for the entire planet’s environment.
Now, Obama seems to be doing his part, but what about the rest of us? We don’t have to sit back and let one man make all the changes. We can plant trees, drive less, exercise more by walking or biking, use natural resources, natural beauty products, quit using plastic, recycle more, anything it takes.
President Obama has already made drastic improvements in the condition of our planet’s fading health. Obama has decided that the elimination of child lead poisoning should be one of his top priorities - we can’t even believe that is still a problem in today’s society! Obama is also working on a number of different efforts to try and help increase access to and use of renewable fuels, rather than fossil fuels.
When Obama was in the Senate, he was able to pass legislation which gave gas stations some sort of a tax credit for installing environmentally healthier E85 ethanol refueling pumps. Also, as for the hugely debated issue of global warming, Barrack Obama has tons of great ideas to put a stop to the trend.
On Barrack Obama’s website, Barackobama.com, the President says that the issue of our planet’s climate change is one that people ignore at their own peril. There could still be debate about exactly how much people are contributing to the heating of the Earth’s atmosphere, or how much is naturally occurring. He also said that what we can be scientifically sure of is that our constant utilization of fossil fuels is sending us to a point of no return.
As part of President Barrack Obama’s plan, he is going to be developing some domestic incentives that reward farmers, forest owners, and ranchers whenever they restore grasslands, plant trees, or undertake any farming practices which reduce carbon dioxide from the atmosphere, while at the same time doubling funding for science and research to go towards clean energy projects that include those that make use of our solar and wind resources, and biomass. Even still, more than a few citizens find these plans to be less than acceptable.
In a past debate between Obama and another Democratic presidential candidate, Hillary Clinton, she said that there was an energy bill passed in 2005 was bombarded with all sorts of additional interest breaks and giveaways to the major oil companies. When Barrack Obama was senator, he voted for it, according to Clinton. She claims she did not vote for it because she knew it would turn out to be an absolute nightmare. Whether this is true or not, we don’t know, but all that matters is that our only environment is kept as healthy as possible.
What can we do? As mentioned before, be lest wasteful. Don’t keep the water running while you brush your teeth, don’t shower any longer than you need to. Don’t throw away your bottles of shampoo, makeup, or whatever if they’re sort-of empty. Squeeze as much out as you can, get it all out. This way, we don’t have to buy so much, which will eliminate production - and save packaging / paper / gasses emitted / etc. Make your own homemade beauty products instead of buying packaged products. In the middle ages, and even in the early 1800’s, they made their own products, and they were fine!
So you see, there is so much you can do. Just keep the environment in mind before everything you do. It’s the only Earth we got!
