Not Just For Movies Anymore

As mentioned by President Bush in his State of the Union speech, the United States has a bad oil addiction. Throw in the negative environmental impact of using fossil fuels, and it becomes apparent a change is needed. As we look around for alternative energy sources, biomass is becoming a popular choice. Biomass is simply energy derived from the burning of bio fuels such as animal waste and excessive crops.

As people starve around the world, it is sadly ironic that we have a major surplus of corn. Corn makes an excellent biomass power source. This is because corn packs a serious amount of energy in each kernel. When used with a heating system, they produce as much heat as traditional furnaces, but at a much lower cost.

Biomass corn energy is produced using dry shelled corn as the power source. Unlike the edible variety, the corn does not have to be of high quality stock. Pretty much any shelled corn will do so long as it is dry and free of husk fibers.

Corn is turned into heat for a home much the same way as wood. The process involves a fired stove with corn being used instead of wood. If you’re picturing standing in the snow with a shovel, you will be happily disappointed. These days, shelled corn is delivered to your home where it is stored in a tank. As the heating system requires additional fuel, a thermostat senses the loss in temperature and opens a door in the storage tank. A pre-set amount of corn falls into the furnace and, ta da, you have more fire and more heat. The heat is then piped into the home through the same duct system used with an electric heating system.

Generally, burning corn for heat will cost you half as much as oil produced energy, 30 percent less than coal produced heat and 70 percent less than heat produced with natural gas. If you’re buying energy to heat your house from a utility company, converting to a corn can save you as much as 75 percent.

At first mention, using corn as a fuel source might seem “out there.” In truth, it is the most searched type of furnace on the Internet. That should tell you something about its popularity and viability.

Biomass fuel is also known as Bio-fuel. Bio-fuel is defined as liquid, solid or gaseous fuel that consists of biomass. Biomass fuels can be used for generating power and also for heating purposes.

Biomass fuels can help greatly in reducing the various greenhouse gas emissions and at the same time can increase energy security by being an alternative to fossil fuels. Today, you will find expansion of bio-fuel industries in Asia, Europe, and America.

Bio-fuels are most commonly used in automotive transport like the E10 fuel. They can easily be produced from any source containing carbon like plants. Biomass is mostly derived from living organisms, which includes animals, plants, and their by-products. Manure, crop residues and garden waste are some of the different sources of biomass. This is a renewable energy source that is associated to the carbon cycle as compared to various natural resources like coal, petroleum, and nuclear energy.

Some of the most popular agricultural products that are grown for the purpose of creating Bio-fuel in the United States are soybeans and corn while Europe uses wheat, rapeseed and sugar beet; sugar cane is grown in Brazil, Jatropha in India and palm oil in South-East Asia.

In the early part of 2007, Diversified Energy Corporation with the help of North Carolina State University (NCSU) geared itself for a breakthrough in biofuel technology, which has been named Centia. Centia has been positioned for producing military and commercial jet fuel and can even act as a biodiesel additive in cold or freezing weather. The process of developing Centia looks promising and is expected to deliver a high energy efficiency level that can be in excess of 85%.

There are a wide variety of scientific experiments being conducted, globally, to produce a viable bio-fuel that will be efficient and environmentally friendly. Scientists have started to look beyond the bio-fuels and started to work on the various byproducts of bio-fuel that can be used and even consumed as food in our daily lives.

Considered as an integral part of the green revolution, bio-fuels offer quite a few advantages over other fossil fuels like coal and petroleum. Bio fuels have the ability to recycle carbon dioxide with every growing season by getting it from the air to convert it into biomass. So unlike coal, which upon burning releases carbon, biomass in a way traps all the carbon that is in the air. This is an important aspect from the point of view of global warming because it doesn’t release any carbon components into the air. The biggest advantage over conventional fuel is that bio-fuel is renewable and hence they will not deplete the limited natural resources of our planet.
Common Biomass Fuels
Here is a list of some of the most common first generation Biomass fuels:

Vegetable oil
Vegetable oil is used for cooking food and also as a fuel. Vegetable oil is not high quality oil for fuel use but it is still used in older diesel engines, which are equipped with an indirect injection system.

In most of the cases, vegetable oil is used for manufacturing bio-diesel that is compatible with most of the diesel engines. It is normally blended with conventional diesel fuel for optimum efficiency.

Bio-diesel
Bio-diesel is one of the most common Bio-fuels in Europe. It is produced mainly from fats or oils using the process of trans-esterification. It is a liquid that has a similar composition like that of mineral diesel. The chemical name for bio-diesel is fatty acid methyl ester (FAME).

The oil is mixed with methanol or ethanol and sodium hydroxide, which initiates a chemical reaction to produce glycerol and bio-diesel (FAME). The process produces 1 part of glycerol per 10 parts of bio-diesel.

Bio-diesel is extensively used in diesel engines after it is blended with mineral diesel. Some countries like Germany have manufacturers Volkswagen, who provide a cover on their diesel engines as a part of their warranty for 100% bio-diesel use.

A majority of vehicle manufacturers still limit to use of 15% bio-diesel blended with mineral diesel. In some of the European countries, 5% bio-diesel blend is widely used and even available at gas stations

Bio-ethanol
Ethanol is one of the most common Bio-fuels across the world. It is also known as an alcohol fuel and is produced by fermenting sugars, which are derived from corn, wheat, sugar cane and sugar beet. The various production methods for ethanol are fermentation of the sugars, enzymatic digestion, distillation and drying.

The use of Ethanol has been widely seen in petrol engines where it replaces gasoline. Almost all the petrol engines in the world can run on 15% blends of bio-ethanol with gasoline.

With an eye on the diminishing natural resources, its time for us to usher in the bio-fuel era!

In most respects, the entire problem can be intimidating and to a certain degree dejecting. Luckily, there are solutions to the world’s power issues if they are simply applied and developed to their fullest and most efficient possibility. Solar power is beginning to make excellent headway in technology and execution as are other alternative energy solutions. One of these alternatives is wind turbine energy, a source of uninterrupted clean energy that is actually making great strides in reducing coal power energy point source where it is being utilized.

What is a wind turbine?

A wind turbine used for producing electrical energy is not all that difficult a thing to comprehend. It is almost exactly like the water wheels that centuries of people have used to make their flour. The only difference is that instead of using water to turn the water wheel wind is used. The wind makes the blades of the wheel turn which; with the help of some gears, magnets and resistance creates electricity which turns a motor to send the electricity along power lines. Unfortunately, at the moment the energy generated from the turbine cannot be stored in batteries so there is a need for back-up systems but, for the most part, it is a fairly efficient system.

Location, location, location

This last point about not being able to store the generated energy in batteries for later use puts quite a bit of emphasis on where the wind turbines are placed. Since the energy that is generated needs to be sent along the power lines and used right away, the turbines need to be located in a place where the wind is always blowing. One might think, well that shouldn’t be that difficult. Well… yes and no. The turbine needs to be located where there is a constant and steady wind most of the time, but it also needs to be located in a place where quite a few turbines can be located.
The current issue is that one turbine generates quite a bit of energy, but not enough energy to make it economically feasible. Several hundred turbines need to be in place to make this happen. There are many places around the world where this is possible, but the overall concept is regional in nature. In other words, the power made in Vegas, stays in Vegas. The power generated in West Texas, stays in west Texas. This is not generally a bad thing since larger cities in Texas are deriving a nice chunk of their power from the wind turbines which lessens the need to use coal power needed for other places like Los Angeles.

Not in my back yard

The particular problem of people not wanting to look up at or listen to wind turbines all day every day has become a bit of an issue. At the larger more rural sites in West Texas there is a bit of an undercurrent about the wind turbines, the sound they make (constantly) and their future when they are outdated and need to be removed, but since the entire concept is so new the legislature is in a bit of a learning curve. Where the issue is likely to be resolved is in more urban areas where the use of wind turbines is just beginning to creep in. As vocal suburbanites hear about proposed “turbine farms” they all-of-a-sudden decide they are fine with wind power but don’t want to look at 100 turbines within their sight on a mountain top, coastal sound or back yard.

Reading in the dark

People may become vocal about not wanting to see or hear wind turbines on a daily basis but they may need to better understand that alternative power sources are coming. They had better think about the need and how they are going to deal with the issue on a personal basis. Power up with solar, wind, water of nuclear because choosing a source sooner rather the later may be the best way to keep; not in my backyard, not in my back yard.

Some suggest that the solution might be found by making innovative technological improvements to an existing source of energy- nuclear power. Currently, nuclear power supplies 16 percent of the world’s energy.

Unlike coal, natural gas, or oil-all nonrenewable and subject to price volatility-nuclear power plants are fueled by uranium, a relatively abundant element that occurs naturally in the earth’s crust. Plus, nuclear energy is the world’s largest source of emission-free energy. Nuclear power plants produce no controlled air pollut-ants or greenhouse gases.

One of the latest developments in the production of nuclear energy comes from Westinghouse Electric Company. It has introduced what’s been described as the safest and most economical nuclear power plant available in the worldwide commercial marketplace-the AP1000. It’s the first reactor of its class to receive Design Certification from the Nuclear Regulatory Commission.

Based on 20 years of research and development, the reactor builds on the proven technology of major components used in current Westinghouse-designed plants. These components include steam generators, digital instrumentation and controls, fuel, reactor coolant pumps and integrated engineering-and have years of reliable operating experience.

Using this established technology as a jumping-off point, the innovative design of the reactor is said to offer distinct advantages over other reactors-including unequaled safety, economic competitiveness and improved and more efficient operations.

The AP1000’s innovative approach to safety reduces the need for human intervention and the potential for human error. Its simplified construction design can lead to significant savings in plant costs and an accelerated construction schedule.

In the U.S., the Department of Energy (DOE) is also concerned about protecting our environment and resources. To address these issues, the DOE recently issued a mandate that now requires all new, central air conditioners manufactured after January 23, 2006, to have a seasonal energy efficiency ratio (SEER) of at least 13. SEER is a number similar to miles-per-gallon in cars; the higher the SEER, the more efficient your air-conditioning system.

According to the DOE, the 13 SEER standard is forecasted to save the nation 4.2 quads (quadrillion British Thermal Units) of energy over 25 years (2006 through 2030). This is equivalent to the energy consumed by nearly 26 million American households in one year. The standards are also expected to save consumers $1 billion over the same period.*

Manufacturers like the Unitary Products Group of York-a Johnson Controls Company, haven’t stopped at 13 SEER. York® also offers new home-cooling systems that reach 15 and even 18 SEER.

Much of the improved efficiency associated with 13 SEER units is the result of an increase in the surface of the coil found in a system’s outdoor unit, which is used to transport refrigerant. As a result, these outdoor units can be 50 to 90 percent larger than 10 SEER units and require as much as 40 percent more refrigerant than many indoor coils are capable of holding. It becomes very important, then, to match the size of the indoor coil with the new, larger outdoor unit.

A mismatched system can lead to lower comfort levels, a higher utility bill, increased stress on the system and large repair costs. A qualified dealer can make sure your system is matched and installed correctly and is efficient and economical to operate.

So, if you are considering replacing or upgrading the HVAC system in your home, talk to the experts at York. They can help you select a qualified dealer, who is equipped to maintain, repair and/or replace the components of your system.

The sun-directly or indirectly-is the primary source for most forms of energy found on Earth. Solar energy is clean, abundant and renewable.

Though we think of solar power as a new discovery, ancient civilizations found innovative ways to use solar energy. Among them, the Greeks, Romans and Chinese all developed ways to use solar warmth for their homes, including using southern exposures to maximize solar heating and making use of solar lighting.

Now, thanks to innovative technologies, it’s possible to capture this energy, concentrate it, store it and convert it into electricity.

Sunlight is converted into electricity using solar cells. Solar cells are also called photovoltaic cells, or “PV cells” for short. PV cells were first developed in the 1950s for use in American space satellites. Today, they are used for power needs ranging from telecommunications to rural electrification. PV cells can be found on items we use daily, such as calculators, flashlights, radios, landscape lighting and children’s toys.

Portable PV units are also available for emergency and disaster use, such as keeping cell phones and small appliances charged when the user is away from the grid or during blackouts.

Consumers can harness the power of the sun for themselves more easily than ever. Solar panels you see on buildings and homes have been available on the market for decades. New systems-which incorporate solar into roofing shingles-are now aesthetically pleasing, efficient and durable.

2006 ushers in new tax credits for solar energy technologies and consumers may also be eligible for state rebates.

For more information, consult with a tax professional, contact the Internal Revenue Service at www.irs.gov, or check out www.doe.gov for the latest in tax credit information.

Sunlight isn’t only used to generate electricity. It is also used to heat water, which can be used to warm homes and businesses. Solar-powered radiant heating systems run some industrial processes and drive turbines to generate electricity. Many solar thermal technologies have been used in homes for decades and can last more than 20 years.

Experts believe that solar energy technologies can benefit this nation in many ways. They have the potential to help diversify this country’s energy supply, reduce the dependence on imported fuels, improve air quality, offset greenhouse gas emissions and stimulate the economy by helping to create jobs in the manufacturing and installation of solar energy systems.

As Remi Wilkinson, Senior Analyst with Carbon Free, puts it, inevitably, the growth of distributed generation will lead to the restructuring of the retail electricity market and the generation, transmission and distribution infrastructure. The power providers may have to diversify their business to make up for revenues lost through household energy microgeneration. She is referring to the conclusions by a group of UK analysts, herself included among them, who call themselves Carbon Free. Carbon Free has been studying the ever-growing trend toward alternative energy-using homes in England and the West. This trend is being driven by ever-more government recommendation and sometimes backing of alternative energy research and development, the rising cost of oil and other fossil fuels, concern about environmental degradation, and desires to be energy independent. Carbon Free concludes that, assuming traditional energy prices remain at their current level or rise, microgeneration (meeting all of one’s home’s energy needs by installing alternative energy technology such as solar panels or wind turbines) will become to home energy supply what the Internet became to home communications and data gathering, and eventually this will have deep effects on the businesses of the existing energy supply companies.

Carbon Free’s analyses also show that energy companies themselves have jumped in on the game and seek to leverage microgeneration to their own advantage for opening up new markets for themselves. Carbon Free cites the example of electricity companies (in the UK) reporting that they are seriously researching and developing ideas for new geothermal energy facilities, as these companies see geothermal energy production as a highly profitable wave of the future. Another conclusion of Carbon Free is that solar energy hot water heating technology is an efficient technology for reducing home water heating costs in the long run, although it is initially quite expensive to install. However, solar power is not yet cost-effective for corporations, as they require too much in the way of specialized plumbing to implement solar energy hot water heating. Lastly, Carbon Free tells us that installing wind turbines is an efficient way of reducing home electricity costs, while also being more independent. However, again this is initially a very expensive thing to have installed, and companies would do well to begin slashing their prices on these devices or they could find themselves losing market share.

One development in solving or maybe reducing the excessive exploration of the natural resources of the earth has been done by the New York State Energy Research and Development Authority (NYSERDA) in order to invite people in the saving energy programs to preserve the earth. The program is done in the form of competition sponsored by NYSERDA to make the New York Citizen to join the Shining Example Competition. The winner of this contest will have the opportunity to win a free compact Energy Star qualified fluorescent light bulb home makeover, a free home performance assessment, and the possibility of being featured in the NYSERDA television commercial and many other interesting prizes.

The New York citizens are able to join the competition by submitting a 90-second video or 250-words essay that shows the reason behind their switching to Energy Star qualified fluorescent light bulb and what it is meant for them, their lives, and their environment. The program has saved more than one million megawatt hours of electricity because of the installment of 16.9 million FLB all over the state. It means that the power of electricity that is saved is similar to more than 165, 000 houses per year. It is hoped that the other states or even other nations can follow the good will of the New York Government to protect the environment.

Nuclear power plants are very “clean-burning” and their efficiency is rather staggering. Nuclear power is generated at 80% efficiency, meaning that the energy produced by the fission reactions is almost equal to the energy put into producing the fission reactions in the first place. There is not a lot of waste material generated by nuclear fission—although, due to the fact that there is no such thing as creating energy without also creating some measure of waste, there is some. The concerns of people such as environmentalists with regards to using nuclear power as an alternative energy source center around this waste, which is radioactive gases which have to be contained.

The radiation from these gases lasts for an extraordinarily long time, so it can never be released once contained and stored. However, the volume of this waste gas produced by the nuclear power plants is small in comparison to how much NOx (nitrous oxide—that is, air pollution) is caused by one day’s worth of rush-hour traffic in Los Angeles. While the radiation is certainly the more deadly by far of the two waste materials, the radiation is also by far the easier of the two to contain and store. In spite of the concerns of the environmentalists, nuclear power is actually environmentally friendly alternative energy, and the risk of the contained radiation getting out is actually quite low. With a relatively low volume of waste material produced, it should not be a difficult thing at all for storage and disposal solutions for the long term to be developed as technology advances.

The splitting of an atom releases energy in the forms of both heat and light. Atomic power plants control the fission reactions so that they don’t result in the devastating explosions that are brought forth in atomic and hydrogen bombs. There is no chance of an atomic power plant exploding like a nuclear bomb, as the specialized conditions and the pure Plutonium used to unleash an atomic bomb’s vicious force simply don’t exist inside a nuclear power plant. The risk of a “meltdown” is very low. Although this latter event has happened a couple of times, when one considers that there are over 430 nuclear reactors spread out across 33 nations, and that nuclear reactors have been in use since the early 1950s, these are rare occurrences, and the events of that nature which have taken place were the fault of outdated materials which should have been properly kept up. Indeed, if nuclear energy could become a more widely accepted form of alternative energy, there would be little question of their upkeep being maintained. Currently, six states in America generate more than half of all their electrical energy needs through nuclear power, and the media are not filled with gruesome horror stories of the power plants constantly having problems.

One of these alternative energy resources is wind power. Wind turbines continue to be developed that are progressively more energy efficient and less costly. “Wind farms” have been springing up in many nations, and they have even become more strategically placed over time so that they are not jeopardizing birds as former wind turbines did.

Another alternative energy resource is the one that is most well known: solar energy. This involves the manufacturing of solar cells which gather and focus the energy given off directly by the sun, and translate it into electricity or, in some cases, hot water. As with wind energy, solar energy creates absolutely zero pollution.

Ocean wave energy is seen by governments and investors as having enormous energy generating potential. A generator in France has been in operation for many years now and is considered to be a great success, and the Irish and Scots are running experimental facilities.

Hydroelectric power has been with us for a while and where it is set up, it is a powerful generator of electricity and cleaner than a grid. However, there are certain limitations to the availability of the right places to set up a large dam. Many run-of-the-river, or small and localized, hydroelectric generators have been set up in recent times due to this limitation.

Geothermal energy is extremely abundant, since it lies directly beneath our feet, just a few miles below the earth’s surface. This energy is produced by the heating of water through the actions of earth’s fantastically hot molten core. The water turns to steam, which can be harnessed and used to drive turbine engines which in turn generate electricity. Great amounts of research and development should be put into geothermal energy tapping.

Waste gas energies, which are essentially methane, reverse the usual energy-pollution relationship by creating energy from waste that lies in the dumps and from some air pollutants. This gas is used in fuel cells and can be used in standard gasoline generators.

Ethanol is a gasoline substitute and is created from such things as wheat, sugarcane, grapes, strawberries, corn, and even wood chips and wood cellulose. There is controversy over this fuel with regards to its ever becoming truly economical or practical except in very localized areas, but technologies for its extraction and admixturing are continuously being refined.

Biodiesel energy is created out of the oils contained in plants. So far, the commercial stores of biodiesel have been created using soybean, rapeseed, and sunflower oils. At the time of this writing, biodiesel is typically produced by entrepreneurial minded individuals or those who want to experiment with alternative energy, but commercial interest from companies is on the rise. It burns much cleaner than oil-based diesel.

Atomic energy is created in atomic energy plants using the process of nuclear fission. This energy is extremely efficient and can generate huge amounts of power. There is concern from some people about what to do with the relatively small amount of waste product atomic energy gives off, since it is radioactive and takes hundreds of years to decay into harmlessness.
