Two Environment-friendly Alternative Energy Options for 2015

alternative energy posterThe energy requirements of mankind have, for too long been met by the traditional mode of energy constituted by the non-renewable carbonaceous fossil fuel fuel sources. It is no wonder that numerous brand-new alternative power sources are now progressively being looked for by consumers and governments alike.

Let us be clear to avoid any unwanted concerns in the minds of our readers, we are not actually in danger these times when talking about fuel sources, since there are still vast supplies. But, the average person will be severely influenced if their house and/or garden (yard) gets polluted by the increasingly more intrusive methods being used to gain access to fossil fuel sources. These can be, like fracking, quite risky to water supplies and wildlife, so our best option now is to look for an alternative power system that is earth friendly and expense conserving.

The Wind Power Alternative

One great alternative power source that individuals and companies have begun to harness today is the use of wind energy. The idea of the wind energy systems is just quite simple. The wind presses on to tilted blades, therefore the blades move. The blades are connected to a hub which in turn runs other elements or parts. It is simple, and it works well WHEN THE WIND BLOWS.

However, what society really needs most is power which will be available in all weather condition conditions, and patently wind power is an alternative energy source that fails on that score. A process known as Anaerobic Digestion produces energy as biogas, this can be burnt for electrical power and that does provide 27/7 power, and it does it 365 days of the year, so lets consider it further in the rest of this article.

Anaerobic Digestion for “Alternative” Biogas Power

Anaerobic digestion is a collection of processes by which microbes break down naturally degradable material in the absence of oxygen. The process is utilized for industrial or domestic functions to manage waste and/or to produce fuels. Much of the fermentation used industrially to produce food and drink items, in addition to house fermentation, utilizes anaerobic digestion.
Anaerobic digestion is able to use nearly any natural product, and has for years commonly been used for effluent and sewage treatment. Anaerobic digestion, a basic process, can substantially reduce the amount of organic matter which might otherwise be destined to be dumped in landfills, or scorched in incinerators.

Anaerobic digestion produces biogas with a high proportion of methane that might be utilized to both heat the tank and run engines or microturbines for electrical energy to power other on site procedures, and for sale to the power companies. In big treatment plants sufficient energy can be created in this way to produce more electrical power than the machines require. The methane generation is a key benefit of the anaerobic process. Its vital downside is the long time needed for the process (approximately 30 days) and the high capital expense, however it does produce consistent power which solar and wind and many other renewable resource technologies do not.

Methane and power produced in anaerobic digestion facilities can be used to replace energy derived from fossil fuels, and for this reason lower emissions of greenhouse gases, because the carbon in naturally degradable product is part of a carbon cycle. In contrast, carbon in fossil fuels has been sequestered in the earth for many millions of years, the combustion of which enhances the total levels of carbon dioxide in the environment.

Improvements In Biogas Plant Process Designs Are Happening

Recent, trademarked developments in the anaerobic digestion procedure, namely the Advanced Anaerobic Digester System (AADS), have led to both consecutive batch reactors (SBR) and continuous procedure plug circulation designs that are highly automated and are subsequently much lower in annual operating expense. These systems are also readily scalable from 50 Animal Unit installations supporting a 25kW engine generator to Biogas generators encouraging of 20 Megawatts or more of equivalent electrical generation, boiler horsepower, or heating system fuel.

The application of programmable logic controllers (PLCs), coupled with oversight by a local, commercially offered and trusted digital control system (DCS) software application assures high efficiency dependability and results. Heuristic algorithms, self tuning capability, and the ability to perform Data Mining from the collective AADS database will certainly ensure constantly improving operational efficiency and promote further research into anaerobic bacteria populations and their responses to changing ambient conditions.

Reduced Transport Costs When Waste Is Digested

In countries that collect home derived waste, using regional anaerobic digestion facilities can assist to reduce the amount of waste that needs transport to central landfill sites or incineration centers, and that is everywhere in the developed world. This decreased burden on transport reduces carbon emissions from the refuse collection vehicles (RCVs). If localized anaerobic digestion facilities are embedded within an electrical power grid network, they can help reduce the electrical losses related to carrying electrical power over a national grid. In addition, there are many organic waste sources not yet being used, so this can end up being a real alternative energy source, producing say up to 50% of the power needed to heat a country’s homes.

Not Making Energy From Waste Would Be A Waste!

The growing need for energy and for that energy to be “green” and not from a non-renewable fuel source, which adds to the greenhouse gas impact and climate change effect is provided for by anaerobic digestion. Utilizing this procedure there are lots of methods that waste, with its secured energy, can be made use of as a fuel source, so one of the very best, if not the best, alternative energy source should surely be Anaerobic Digestion.

Admittedly, one great alternative power individuals have been start to harness right now is the use of wind energy. But, anaerobic digestion can do better as a baseline power source, unaffected by weather changes. Its disadvantage is the long time needed for the process (up to 30 days), meaning large digester tanks are needed, and hence the high capital expense, but critically it does produce constant power which solar and wind and lots of other renewable energy technologies do not.


Methane and power produced in anaerobic digestion centers can be utilized to replace energy obtained from fossil fuels, and hence reduce emissions of greenhouse gases, due to the fact that the carbon in eco-friendly product is part of a carbon cycle. Current, patented developments in the anaerobic digestion process, specifically the Advanced Anaerobic Digester System (AADS), have resulted in both sequential batch reactors (SBR) and constant process plug circulation designs that are extremely automated and are subsequently much lower in annual operating costs. If localized anaerobic digestion facilities are embedded within an electrical circulation network, they can assist lower the electrical losses associated with transferring electricity over a national grid and become a real alternative energy source.
