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. You will obviously be familiar with wind turbines and generating electricity and how solar PV panels can also be used. 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. Biomass which includes wood does not place additional carbon into the atmosphere during combustion.

A process called gasification can turn material such as wood, 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. Therefore to create an automated low maintenance process 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.

You can now purchase solar shingles that look like your existing asphalt shingles. They have a comparable matte finish and are the same size. The big difference is that they are covered with thin film solar cells that collect sunlight and turn it into electricity. The thin film technology means you won’t have to assemble a large structure (an array) on top of your roof to hold solar panels. And the solar shingles will collect the same amount of energy as a solar panel array, but are much less visually intrusive.
Some homeowner associations won’t consent to solar panel arrays to be built on a rooftop or in a back yard. And even if you still have to get your homeowner association to allow you to install solar shingles, it will be much easier to convince your neighbors (and board members) to say yes to solar cells that look just like the shingles on their roofs.
Solar shingle systems can be off-grid or tied to the grid. These means they can be used with a solar energy system that is self contained (off-grid) or that is tied into the public utility system (tied to the grid). The thin film technology works chiefly the same way as the bigger panel systems. Sunlight is still being captured by photovoltaic cells and converted into energy. but the materials used in manufacturing the solar shingles are smaller. Advancements in solar technology have allowed improvements that decrease the size needed to produce the same amount of energy. The smaller shingle-sized cells are now efficient enough to produce the same amount of energy as the larger arrays.
Besides the visual appeal, an additional good feature of the solar shingles is that they can be replaced as easily as traditional shingles. They’re made to last for more than 20 years, depending on the manufacturer. And they’re built to withstand harsh weather like hail and high winds. But if they do need to be replaced, it’s as easy as replacing traditional asphalt shingles.
Still, these solar shingles are comparatively new on the market, so you may have to do some research to find a supplier near you. You will also need to find a trustworthy installer who is familiar with the product. your best bet is to search online for solar shingle manufacturers and suppliers. they will e able to refer you to a professional installer in your area.
While solar shingles may not be the right choice for every homeowner, they can certainly offer an attractive alternative to traditional solar panel arrays.
A source of energy that should not be overlooked is wind power. Many homeowners have reduced or eliminated their electricity bill by building their own windmills. More information can be found at www.GreenLivingRocks.com

There is a lot of talk about solar energy being a way out for the world’s energy problems. But wouldn’t it be prudent to know if there are any dangers or hidden negative issues before starting a large project? Here are 3 things to think about before you spend your money:
1) Toxic materials. Some of the materials used in the newer thin film solar panels are toxic to the environment. Even though this only becomes a dilemma when you dispose of the solar panels (which probably won’t be for another 20 years or more), it’s imperative to know that the panels will need safe disposal when that time comes. But new disposal and recycling methods are being researched and developed. Hopefully, they will be in place by the time you need to use them.
2) New Technology. If you read the news about solar energy research, you will be astonished at the number of companies that are developing new systems and products. Solar energy research is a worldwide growth business, with new discoveries being made every month. There is a real temptation to hold off on your solar energy project so you can use the latest technology. But not every experimental product with market potential actually makes it to the consumer. Solar panels are no different than any other new product in the process of research and development. Now and again the best ideas just don’t work out as expected, or are just too costly to produce. So it’s always a bit of a gamble to wait too long for breakthroughs in new technology. You could be unnecessarily wasting several months or years of using your solar energy system.
3) Old Technology. Are you afraid of buying your solar energy system right before the next new product breakthrough? This dilemma is the other side of the coin from waiting too long for a breakthrough. The fear is that a less expensive and better technology is right around the corner, but you just spent thousands on “old” technology.
You can do a lot to prevent this scenario by doing a little research on the internet or the library. There are professional business journals that have the latest news on industrial R and D (research and development), and forecast when new products will reach the consumer market. But many of these journals cost several hundreds or thousands of dollars for a yearly subscription, so only libraries can afford them. If your library doesn’t subscribe, ask your librarian to get it for you. Then you’ll need to decide whether you want to wait for the newest product, or go with a traditional system that might be more reliable and predictable because it has withstood the test of time.
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. Burning pellets is far more efficient than burning other solid fuels including logs and coal. 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. In the developing world, cooking is also an area of interest for pellets.

Powerless but highly efficient cooking stoves 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. Simple wood fires are highly inefficient and most of the energy of the wood is wasted. 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. As these stoves have no moving parts they are also cheap to produce, which is important to try and speed up improved combustion technology adoption.

Why pellets play such a crucial role is the ability to use other fuels than simply just 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.

It’s no secret at all that the globe is facing an energy crisis. With fossil fuels costs rising, and need growing higher than ever, individuals are scrambling for alternatives. Sadly, much of the alternatives have some major drawbacks which prevent them from being effective options at this point.
Insert concentrated solar energy. Though its certainly not ideal yet, this technology shows some huge promise for giving clean electricity well into the future. Solar electricity is not a fresh thought at all, and a lot of photo voltaic based plants (standard “solar panels”) have already been constructed, these plants are quite expensive due to the cost of the panel supplies, and take up enormous amounts of land to be successful. Even worse, as soon as the sun stops shining, the electricity stops being produced.
Solar energy solves these setback by taking a completely different design. Rather than converting the sunlight straight to electricity, as sloar panel panels do, solar power systems employ some sort of reflector dish to concentrate the sunlight into a small area. This intense sunlight is then used to heat fluid inside an absorber tube. Think of shining a magnifying glass onto a test tube of water. This heated fluid is then transferred to a heat engine, which converts the heat into power.
This system has several advantages. One of the most notable advantages is that because the heat fluid can be store in insulated reservoirs until needed, solar power plants can produce electricity at nigh and on overcast days, which is a huge plus in an actual energy system, where the load is 24 hours a day. Storing power as heat is much more effective that storing it as electricity, so these plants will have a enormous leg up in this area. Another cool feature of solar thermal is that it could be used to help desalinate salt water, making it a doubly useful resource in coastline areas.
Another advantage of solar thermal electricity is its great dependability. Since the system is quite straightforward, running a solar plant based on the technology will not take alot of an effort. For the reason that of this, these electricity plants can last long into the future, providing energy for years to come.
It has been anticipated the the United States energy requirements could be satisfied by a 92 by 92 mile grid of solar energy generators. This is a enormous number in reality, but it does demonstrate that this could be a practical technology. And indeed, its practicality has been recognized as private investors such as Pierre Omidyar are putting increasing amounts of funding into the business. With this type of foundation, it will be interesting to see where this technology heads in the future.
Though it is certainly not perfect just yet, intense solar thermal power generation has the promise to change the way we think about energy in this country. The dream of limitless, clean, renewable energy may seem a little pie in the sky for some, but the solar thermal technology helps bring it one step closer to becoming a actuality. Keep an eye out, and I forecast you will see solar thermal electricity production becoming a huge player in the upcoming energy revolution.

Global warming is one of the “hottest” issues these days. The present climate change is the worst yet to happen. Global warming is an overall increase in world temperature which is attributed to the increasing number of greenhouse gases trapped in the atmosphere. Searching an alternative energy source is considered a way of reducing the toxic emissions.
Greenhouse gases can be produced both by natural and industrial processes. The most abundant greenhouse gases on earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, ozone and CFCs.
There are a number of sources of greenhouse gases. Burning of fossil fuels and deforestation lead to elevated concentration of carbon dioxide in our atmosphere. Without the trees and plants to take in the carbon dioxide emitted by burning fossil fuels, natural gas and petroleum products, all of the CO2 emitted stays in the atmosphere.
What’s more the use of CFCs or chlorofluorocarbons in refrigeration systems and in fire suppression systems and other manufacturing processes also increases the greenhouse content of our atmosphere. While the use of non-organic fertilizers in agriculture also lead to elevated nitrous oxide concentrations, another greenhouse gas.
In the USA, greenhouse gas emissions mainly come from the use of fossil fuels as energy source. Approximately 82 percent of the greenhouse gas emission in the United States in 2006 came from the combustion of coal, natural gas and petroleum (United States Energy Information Administration). Meanwhile in Asia, China is expected to increase its emission of greenhouse gas because of the construction of old-fashioned power plants in its internal provinces. Presently, the carbon dioxide concentrations in the atmosphere are the highest in 150,000 years. The 1990s were most likely the warmest decade in history, while 1998 was the warmest year (Greenpeace).
Not controlling the greenhouse gas being emitted by human activity can foster climate change the next hundred years that will be much faster than anything known and recorded in history. There are necessary steps to be undertaken to control the toxic emission that will soon be killing us.
To diminish the consumption of oil, petroleum and other fossil fuel, we should use energy efficiently. Energy that we use should be generated from renewable energy source, which would mean harnessing the natural energy from the sun, winds, crops, tides and waves.
Green energy is another term used to explain sources of energy that are considered to be environmentally friendly, which is also analogous to the renewable sources of energy.
There are copious ways of generating electricity and energy from renewable and natural sources that generate clean and safe energy. Wind, sun, and heat can generate electricity for less cost and less carbon emission than those of coal and even gas.
Shifting the world’s attention to alternative fuel source rather than relying on fossil fuel is one of the solutions in resolving the harsh climate change. Greenpeace cited that with renewable energy and using it smartly, can deliver half of the world’s energy needs by 2050. Greenpeace also cited that it is feasible to reduce carbon dioxide emission by almost 50 percent within the next 43 years.
Governments are taking steps to use and tap alternative energy sources as main source of energy. The European Union leaders made an agreement in March 2007 to ensure that 20 percent of their nation’s energy should come from renewable fuels by 2020. This is part of their effort to reduce carbon dioxide emissions and other greenhouse gas. There are even governments offering incentives to their populace who are using green energy.
Alternative energy source may not be the only way to reduce the greenhouse emission that human activity produce. There are simple ways in which we can do to contribute in reducing toxic gas emission and mitigate global warming.
Geocaching is an up-and-coming outdoor hobby, quietly gaining in regard internationally. Its primary purpose is recreational, and there are literally thousands upon thousands of hidden caches that cover the globe. More creative uses are being found for GPS all the time.
Spinning off of geocaching for recreational use, the “sport” can also be utilized for purposes having to do with survival. We’ll now take a look at some of the ways that a GPS unit can be employed from an emergency preparedness point of view.
There are a ton of good reasons to record waypoints (longitude and latitude coordinates) for survival purposes. For starters, it would be prudent to record a isolated camping spot that you have identified as being suitable to set up your living quarters and that is good for sustaining wildlife and other living things. It shouldn’t be too far away from water, and not be so well known that it becomes overloaded and unproductive. Along with this site you should also record coordinates of nearby edible plants, roots, and berries. These should be researched well, and you should be certain that they are in fact edible and are not poisonous or contain other toxins. A field guide with pictures and descriptive text will help you to identify the ones your body can safely digest.
Further along the “trail” you may decide to indicate a spot that is rife with critters for you to trap. These may just end up being a reasonable source of meat for you; after all, everything tastes like chicken anyway, right? Dig a deep, wide hole that you can put some sturdy plywood over and cover with dirt to function as your cooling unit for foods that require refrigeration. You might also decide to do something similar for other items you’d like to store, such as an axe, flint and steel, a saw, a pair of binoculars, or whatever. Remember to record all of these waypoints.
Another extremely useful waypoint for your deliberation is a cave. If you are able to find one that you could fit in and use for protection, by all means record this, too. While were on the subject of survival, make yourself a hooter dart. If you got hungry enough you might kill and cook up some bat. Who knows, it might be a gourmet food (somewhere in the world).
Now, this is not meant to be an episode of Fear Factor, so settle down. But you might need some strange or unusualsources of protein in an emergency/survival situation. So mark a location where you have witnessed in great amounts the following: red ants (bigger and tastier than the black variety), grasshoppers, and night crawlers. These won’t all likely be plentiful in the same location, so look around and record your results accordingly. And remember, protein is a must– why do you think when the food bank comes around asking for foodstuff donations, items high in protein are at the top of their list for requested items? Chocolate gives most people pleasure. Just melt some chocolate over the campfire and cover these creatures to eat them for practice.
The next thought for something to mark is a honeycomb. Look around for some wild honeybees. If you find their home, and it’s near enough to the ground, bingo! If it is in a hole in a tree, for example, and you could do with something sweet (and you were feeling really adventurous) you could build a fire at the base of the tree to smoke them into a spellbinding state while you stole away their golden juice!
To sum things up, these are a few of the serious and not so serious (but plausible, nonetheless) ideas of waypoints that you might want to record now before an emergency happens. Don’t forget to record an zone jam-packed with dry wood for fire making. The reason for recording all of these coordinates is for all of you folks with Halfheimer’s that forget the simplest things from one second to the next. But seriously, everybody forgets some things, and why risk a excellent find in the outdoors? Record it! Oh, and if you get into some trouble out there… this is a great SPOT to be in!
Watching movies is a neat escape from the stressful lifestyle we live in. Watching movies in a wide screen and surround sound take you far away and into the movie scene you are watching. You watch it as if you were there in the movie scene. Of late, we can only experience this escape in a cinema. However, modern technology may be able to provide this same sight and sound experience right in your own living room. We will discuss the basic components of a home theater system in this article. Read on to understand how these basic components can deliver the best cinematic experience to a home theater system.
Home theater experts state that the most important consideration in setting up a home theater system is the size of the room where you will set up the home theater system. The most important component of the home theater system, which is the television, is dependent on the size of the room. Although, the recommendation is 27 inches television set at a minimum is necessary for your home theater set up. It is also a recommendation that a flat television is good for a home theater system because it exhibits fewer glares and produces a crisper image. Another major component of a home theater system that depends on the size of the room is the speaker. The number of speakers for your home theater system is dependent on the size of the room. You may add up to six speakers from the basic three speakers if you want a more lifelike sound. Adding a subwoofer may also be good to achieve a complete surround sound like in the movie theaters. Three speakers should be the minimum; you may go up to six if the room is big.
Another major for your home theater system is the DVD player. It is a recommendation that DVD players with progressive scan will be the best choice. This is because progressive scan produces sharp and flicker-free pictures. This however points back to the choice of television unit; you may need to check if the flat television set supports progressive scan signals. You may also acquire a five-disk carrousel DVD player. This will avoid having to stand up from your seat to change discs every so often. A minor consideration is the power rating that will determine how loud your speaker can be. Of course, almost all these depend on the size of the room to where the home theater system is going to be set up. Small room requires from few types of equipment, bigger rooms may require more and adding home theater furniture to your home theater system may be best. A bigger room thus requires more investments. A smaller room might require fewer but of good quality equipments to avoid the too basic feel of the home theater system.
Finally, you may acquire a beautifully designed home theater system if you consider hiring a home theater expert. If you can afford this, it will be best for you because the home theater expert will be able to effectively design and set up your home theater system. Your home theater designer may also add some features like home theater seating and other home theater furniture to be able to give the complete home theater package that closely resembles a real movie theater. Having the finest and high-quality home theater system will give you the most sought after set up that you could flaunt and enjoy to the max.

More and more individuals are turning to alternative electricity resources in order to heat and cool their own homes. Everywhere you turn people are looking for more environmentally friendly choices, as well as choices that will save them some money here or there. One of those renewable power sources that individuals are turning to are solar power panels. This power source harnesses the suns electricity and converts it into energy that can be used to power, heat and cool a house. There are many perks when it comes to using solar power to provide electricity to a household, generating this energy resource a popular option among home owners.
One benefit to this specific resource is the fact that it can save home owners a considerable amount of money in the long run. To install in a house does require a significant investment. However, overtime that cash can be earned back. Solar power is able to save home owners cash by using less electricity to power the house. This will save home owners money when it comes to other monthly utility bills. Over time, the money spent on installing them for the house will be earned back by the cash saved by the energy panels.
In addition to saving money on utility statements, solar electricity plates also give home owners with tax breaks. The United States administration offers up to $2,000 to home owners that use it as an form of power. The administration offers incentives to home owners and business owners that use renewable power and who are looking to make better the ecosystem. These tax breaks are just some of the incentives offered to those who are environmentally conscious.
They are one of the cleanest forms of renewable electricity out there. In addition to the money saved by use of the sun, this alternative source is also environmentally friendly. It uses the sun to convert power; therefore it does not require fuel to burn creating emissions. Because there are no emissions from the panels themselves, this means that carbon dioxide, mercury, nitrogen oxide sulfur dioxide and other gases are not emitted into the environment when they are used to provide electricity to a home.
An extra advantage is the fact that this power resource is renewable. The sun is a constant element in the natural world; consequently it will always be there to offer power. Other electricity resources such as coal, natural gas, and petroleum are non renewable and consequently have the promise to run out ultimately. Solar power on the other hand is an endless resource that will always be here to provide electricity.
With all the benefits of plates, there are also some negative aspects of the energy resource as well. One shortcoming to using it is the reality that it requires an original investment in order to offer energy to a house. However, the cash that is used to switch over can ultimately be made up with the amount of cash saved on utility statements. Another disadvantage is the look of the plates on a house. Some individuals do not find them displayed on the roof of a residence aesthetically pleasing. On the other hand, this is a small price you have to pay in order to save power and money at the same time.
All and all there are benefits and disadvantages to each power resource that is out there. It is imperative to investigate what power source is best for your house before you invest in a new energy source. Solar energy panels just could be the right decision for you.
