In today’s Market households are looking for ways to Conserve funds and at the same Point help out the environment. Renewable energy sources such as the magnetic generator can dramatically aid with both of these causes. By utilizing the generator, households today can drastically save money while at the same time help Safeguard the Ecosystem.
Why is it that renewable energy systems seem to be the only things that we buy for our homes and businesses that we expect to “pay for themselves”? Do we Want our toilets to pay us back, or do we Basically expect them to flush as soon as we push the lever? When we Purchase appliances, we may Pick out the one with the Energy Star label because, in the long run, it will Lower our energy usage and save us money. But, do we Look for our appliances to pay us back, to put back into our pockets their Initial expenses?
In fact, we know they will decrease in value. We Assume that they will be worth A smaller amount than we paid for them the day after we Acquire them. The same holds true for our cars. When we buy a car, do we Insist on the car to pay us back? No, we Resign ourselves to the idea that it will always be encumbered in expenses: fuel, insurance, tires, maintenance and repairs, and it will decrease in value, but we Acquire it anyway. After all, we all need transportation to get where we would like to go.
From the first day that we flip the breaker in our renewable energy system to “on”, you will be saving, both money and natural resources. Depending upon the efficiency of the appliances in our homes and businesses, we’ll conserve, anywhere from a Small to a Sizeable amount, on your utility expenses, thereby giving ourselves a Boost in our monthly discretionary spending. Additionally, the warranties on The largest part of renewable components meet or exceed those on the appliances we Normally buy and, as utility costs Increase, The Magnetic generator energy systems will actually appreciate in value.
We all have a responsibility to Upcoming generations to Lend a hand insure that we are taking Charge of our earth so they have the same opportunities as we do.The point is to get started on the Channel To help Establish our own energy
The world is potentially at the Stage of being self sustainable. We Maintain the technology to develop energy to power houses with sustainable resources such as solar and wind but the cost of these products are still what is holding us back. One such product which is making leaps and bounds is the Magnetic Generator. These have been on the market for quite a period but with recent developments they are much more Inexpensive and efficient
Most people tend to contemplate solar and wind power when thinking of a Home-based Natural energy supply. While more and more Individuals are starting to perceive the reward of a third alternative that of magnetic power.

Methods of commercial aquaponic aquaculture are in place in several countries including the United States, Canada, Australia, and Mexico. Although at a much smaller scale than standard agricultural methods, aquaponics are also being utilized to serve a number of developing countries facing climate limitations. Aquaponics methods are a growing commodity still in its infancy stages.
Aquaponic gardening has been used to produce food for centuries in several areas throughout the world to meet geographic needs including Japan, Europe, and Hawaii. Ironically, as transportation and trading resources became more accessible, aquaculture became less necessary and lost momentum. As we face dangerously low fish populations, as well as increasing environmental concerns, it begs us to consider whether we pursued the right course in our food production methods. Fish populations currently face increasing supply pressures and agriculture demands fertile land, soil, and water. These are all decreasing resources against the growing world population.
Commercial aquaponic systems have been revisited and developed and, while still in its early stages, contribute approximately one third of our fishery production today. Of the countries embracing aquaponic aquaculture, China and India are together becoming among the fastest aquaculture providers worldwide. Other countries beginning to lean toward aquaponic food production include Thailand, Japan, and the United States. Aquaponics methodology has long been in its development stages throughout the world, stemming back from as far as the Middle Ages, and, more recently, with the Japanese combining bamboo with fish breeding. It is studied in several universities who are dedicating their own resources to further aquaponic technology.
With the appropriate attention paid to developing a balanced and earth friendly aquaponic system, the result can provide an invaluable world resource. Proper consideration in the feeding of fish and species, as well as prudent care taken in developing a sound waste disposal system (a properly designed system has no waste, recycling the waste product), aquaponic methods stand to save an estimated 90% of water usage otherwise used through standard farming methods. Because water is recycled through an aquaponic system, only a small amount is needed to replace waters used through vegetable growth and evaporation. Air blowers are used to add oxygen to the water to contribute to water purity. Hydroponic lighting is often used to further enhance the quality of production of a system.
Arguably, countries that may stand to gain the most significant benefit from an aquaponic system are developing countries where climate and resources are lacking. Minimal maintenance and cost requirements of feeding, water filtration maintenance, seeding, and ultimately harvesting that create successful sustainable solutions may be managed easily by struggling communities, possibly more so than traditional hydroponics. In an aquaponic system it is estimated that one-half pound of fish may be raised per each gallon of water and vegetable capacity is found to have a shorter growth time. One reported example of successful aquaponics cites approximately 60 thousand heads of lettuce produced combined with 11,000 pounds of Tilapia in a given year.
With the global population reaching an estimated six billion people within the next 40 years it stands to reason that land and water will continue to be invaluable resources and the use of Aquaponics will be the answer to feeding the hungry of the world.

One of the drivers of the trend to large-scale farming is the assumption that there are financial savings and profits to be made from bigger operations.
There is, however, a growing body of opinion that the reverse is true and that food security, diversity and sustainable agriculture may be better achieved by supporting the world’s small and family farmers.
According to the US campaigning organisation foodfirst.org industrial-scale agriculture tends to focus on monocultures because they are the simplest to manage with heavy machinery.
The UK’s Foresight Project and foodfirst.org both argue that small-scale farming is likely to be more diverse, more flexible and more environmentally friendly.
It is probably no coincidence that large-scale operations are referred to as agribusiness, with all this implies about the importance about making a profit for shareholders and also growing what is likely to produce the highest returns, such as the current shift in agriculture to producing biofuels.
The UK farming periodical Farmers Weekly recently published an article arguing that large-scale agriculture represented a threat to small farmers who are already struggling to make a living. Smallholder and family farming is the dominant form of food production throughout the major developing regions of the world, particularly in Africa and Asia. It is also widespread in the developed world.
The most recent World Bank Report says that more and more people are being pushed into extreme poverty by rising food prices. It said that food prices had risen by 36% since April 2010 and predicted that up to ten million more people could fall below the extreme poverty threshold of less than 76p per day in the next few months. That is in addition to the extra 44 million people who have been pushed into food poverty during the last year.
The pressure on farmers to produce more to meet the needs of a growing global population is therefore intensifying and it makes sense to make the best use of all the sources of food production on the planet, large and small.
While small farms are likely to plant mixtures of crops, to use techniques like intercropping and to rotate crops and livestock, with manure serving to replenish soil fertility, they will nevertheless need some support if they are to increase their production.
It is in the areas of access to new agricultural technology, such as low-chem biopesticides, biofungicides and yield enhancers, and to training in their use, where small farmers could most benefit.
Such products are derived largely from naturally occurring sources and would fit well into the mix of existing sustainable small farming methods and techniques to enhance yield and reduce crop loss from disease and damage.
They are expensive to research, trial and license, however, and therefore need strong support from governments, including perhaps financial subsidies, if they are to be affordable for the smaller producers.
Each small increase in production can ony help towards ensuring that there are adequate food supplies for the future, but also there is evidence that small farms producing for local markets increase local prosperity, food security and promote better social cohesion.Tags: food poverty, foresight project, poverty threshold, small scale farming, sustainable food production
Customers and investors are showing more interests in eco-packaging that save raw materials, avoid food waste and enhance recyclability. It has been evident in the recently concluded Cleantech Forum XXII in Copenhagen. Ecopackaging is set to become the next eye-catcher of the clean technologies world.
Packaging accounts for almost 10 % of the environmental impact of anything bought. In developed countries like the U.S. and UK, almost 30 % of food sold in stores is thrown into landfills without even being touched. It is a complete wastage of money and that waste is filling landfills too.
Sainsburys, a waste prompted UK grocery chain, has announced its plans to send all its food waste to biomass stations by the end of the summer in order to produce renewable energy. A number of other companies have started trying to extend the shelf lives of foods, decrease the dependency on petroleum-based plastics bags & packages, and reduce landfill waste, through the use of technologies like nanoparticles, bioplastics, recycled materials, and improved barriers. Also read Active & Intelligent Packaging: Innovations in Food Packaging Industry.
According to Hakan Grubb, CEO of Sweden-based Xylophane, “The need for sustainable packaging is obvious. It’s a regulatory requirement in some places, but we also see consumer demand for it.” Xylophane have developed a barrier material for packaging that decreases food waste by enhancing shelf lives.
Though this sector has started attracting some attention but it still is far away from being recognized. There is big volume of plastics involved everywhere so the market is quite large but the sustainability packaging market’s share is absolutely minimal. Since the field is still in its infancy stage there’s no silver bullet that has emerged. A number of new materials are still in development stage and according to panelists, each advancement needs to be minutely studied for the effects from its creation to disposal. The most important thing is that it has to be as good in terms of barrier properties and should not be more expensive than what it’s replacing.
However ecopackaging companies are not likely to get any premium on their products because consumers and manufacturers aren’t willing to pay extra to be green. Consumers too aren’t likely to adopt ecopackaging if it appears less attractive than what they’re used to. Most of the traditional biodegradable packaging don’t look very good. It has to be at the same level, if not more, because for the user it is a statement of quality.Tags: barrier material, infancy stage, intelligent packaging, landfill waste, sustainable packaging
Renewable & Sustainable Energy (Solar Energy, Wind, Biomass, Hydrogen, Geothermal, Ocean & Hydropower)
Renewable energy is a green technology, friendly with no harm to the environment. Any effort or contribution for spreading the use of this safe technology will result in getting pure sustainable energy & saving our mother earth at the same time.
Renewable energy resources are naturally replenished in a relatively short period of time. They include biomass, hydropower, geothermal energy, wind energy, and solar energy. In 2005, about 6% of all energy consumed, and about 9% of total electricity production was from renewable energy sources. Alternative transportation fuels are fuels used for transportation other than gasoline or diesel. Some alternative transportation fuels, such as ethanol and biodiesel, are renewable while others, such as propane and natural gas, are non-renewable.
The United States currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are nonrenewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources—such as wind and solar energy—are constantly replenished and will never run out.
Most renewable energy comes either directly or indirectly from the sun. Sunlight, Solar energy technologies convert the sun’s light into usable electricity or heat. Solar energy systems can be divided into two major categories: photovoltaic and thermal. Photovoltaic cells produce electricity directly, while solar thermal systems produce heat for buildings, industrial processes or domestic hot water. Thermal systems can also generate electricity by operating heat engines or by producing steam to spin electric turbines. Solar energy systems have no fuel costs, so most of their cost comes from the original investment in the equipment. These are now also being used by many home and farm owners who simply build or buy their own very small solar panels and wind turbines which provide a constant supply of energy in their home or buildings. To try to make solar panels and use renewable energy yourself with lowest cost we recommend homemade energy.
The terms “wind energy” or “wind power” describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like. The sun’s heat drives the winds, whose energy is captured with turbines. These are now also being used by many home and farm owners who simply build or buy their own very small windmills and turbines which provide a constant supply of energy in their home or buildings as well.
Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called biomass energy.
Hydrogen also can be found in many organic compounds, as well as water. It’s the most abundant element on the Earth. But it doesn’t occur naturally as a gas. It’s always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.
Not all renewable energy resources come from the sun. Geothermal energy taps the Earth’s internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean’s tides comes from the gravitational pull of the moon and the sun upon the Earth.
The ocean can produce thermal energy from the sun’s heat and mechanical energy from the tides and waves.
Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. For more information on renewable energy use and benefits please read the other articles by the same author on Articlesbase, Ezinearticles or Goarticles etc..
