-Moving Beyond the Copenhagen Disappointment
The Copenhagen Meet has temporarily halted the progression towards a greener form of existence in terms of not providing a sustainable blueprint for nations to develop in an ecologically compatible manner but the evolution of carbon-free, energy alternatives is carrying on, unhindered. Come 2010 and the focus will continue to revolve around green energy solutions that are practical for further research and have the ability to provide energy solutions for the masses in an immediately adoptable and affordable manner. The following three are some of the green energy solutions that engaged lots of global attention in 2009 and are now on the verge of being presented in a functional manner in 2010.
This concept is the courtesy of Marshall Hydrothermal Recovery System and to be honest, it isn't a scientific breakthrough in any way. In fact, it is something we have always known but never bothered to use for the environment's wellbeing. The core of our planet has extreme heat, generated through a self-sustainable process. Volcanic reactions are the most common, geographical occurrence fuelled by this internal neat The Earth's intrinsic heat is also seen in the form of fissures from where underlying lava is spitted out, or in the form of natural, hot-water springs.Now, a new technology aims to use this heat for mass-production of electricity. This involves the creation of hydrothermal vents that need to be dug near the vicinity of Earth's molten core. The idea is to use special pipes carrying a fluid inside the vents. Once heated, the heated fluid would be pulled back through insulated pipes. The fluid would carry massive amounts of heat energy within it which can be harnessed for generating electricity. There are minimal costs involved in sucking-up the fluid from such great depths, since thermal energy has some physical properties that make it rush towards the upper surface, once heated to a certain temperature. The heat energy extracted can be used to heat water and the resulting steam can be easily used to produce a greener form of hydro-electricity. However, some issues exist as mining to such depths could potentially induce unwanted changes in the Earth's internal stability. Further, the super-heated fluid could burst through the pipes if the temperature-related calculations are not precise, destroying the sub-soil layers. Further, the flow of heated fluid through such a long pipe could affect the quality of minerals embedded under the soil since many of them have metallic constituents that are known to react when subjected to extreme heat. The big advantage lies in the mining aspect for creating the vents. Mining to such great depths seems very doable considering the existing technology being used for offshore drilling projects that have already broken all norms when it comes to penetrating the Earth's crust.
2. Underwater Turbine Technology - harnessing ocean power for household electricity needs
This concept is being developed with the patronization of the Carbon Trust and the Swedish government. The use of the word ‘kite' might seem ungainly to some folks but the fact remains that this is one of the most impressive alternate energy formats that promises to deliver household energy with negligible carbon footprints. The technology is actually a spurned version of a military technology that was developed in Swedish labs. The core concept lies in using a mammoth turbine that has the ability to harness the power of the ocean water akin to a kite being propelled in the air with minimal effort. The basic mechanism is easy-to-understand, wherein the ocean's velocity will be harnessed and to turn an underwater turbine. Although the initial expenditure to establish such a facility would require humongous funding, initial tests indicate that such an underwater turbine would be capable of providing energy over a long period, since the entire configuration is largely self-automated. The product is green electricity in its purest, most environmentally friendly avatar. First-stage testing held at the facility maintained by Saab Underwater Systems, unit of Saab AB, in Motala, Sweden yielded ocean-powered electricity that can sustain the annual, electrical power needs for a majority of United Kingdom's households. Further, the entire concept is also focused upon limiting wastage of power due to issues such as transmission of electricity and costs incurred due to maintenance issues. The biggest incentive for nations to adopt something like this - the fact that there is no present danger of the ocean water currents receding and thus, this form of electricity is ecologically healthier than any other conventional technology being used to power household electricity demands.
US Navy Green Collaboration - setting new benchmarks for green technology collaborations
This technology has already found some acceptability and it has already been interpreted in a noble manner. With terrorism being an international menace, constant and expensive surveillance is critical to ensure that international waterlines are safe. Realizing that such surveillance activities are highly energy dependent and their carbon footprints seem to be rising with every passing year, the US Navy has taken it upon itself to make its international water surveillance greener. It has enrolled the services of Lockheed Martin Ocean Power Technologies to ensure that a large part of its energy needs is procured from power generated by controlling the untapped power of the ocean waves. This could be understood as the first anti-terror collaboration that has a distinct tinge of green and it is bound to become a rolemodel for armed forces across the world to take care of their environmental sensibilities. The basic reason that this technology makes a lot of sense in terms of practical use - ocean waves are persistent around coastal regions and wave energy is more reliable and sustainable than conventional, fossil fuels that are bound to be exhausted in a few decades.
3. Greener Windmills -Along with these two alternative technologies, the concept of wind turbines may re-introduce itself as a more practical green energy solution in 2010. The first step has been taken in this realm by Ridgeblade. Their breakthrough wind-turbine solutions are being retailed through Power Collective. The emphasis is upon making turbine-generated electricity more undemanding. Hence, rather than using gigantic standalone windmills that don't have urban acceptability, the Collective installs industrial blades attached to a turbine, upon a building's roof!! The blades have been constructed from low-density but sturdy material to ensure that they move even when the wind's velocity is at a bare minimum. Being attached to the roof means that the power generated through the attached turbine is immediately used for the building's daily, electrical requirement. This also minimizes wastage due to transmission of electricity from faraway windmill destinations that are presently the norm. Further, the entire structure is much lighter, easier to set-up and more affordable for commercial spaces that have usually struggled with adopting green power solutions.
2010 can prove to be a groundbreaking year in terms of international communities becoming more sensitized towards the cause of a greener existence. However, it should be remembered that unless this approach is spread across a global scale and struggling economies aren't helped to graduate towards a greener way of development, green lifestyles might continue to remain a restricted phenomenon. We can only hope that the failures of Copenhagen 2009 will help nations focus more upon bridging their regional differences and overcoming hostile attitudes for the sake of finding a mutually beneficial platform of sustainability rather than using it as an excuse to wash-off their hands from their collective responsibility of saving the planet.
