Green Technologies Capable Of Salvaging The Environment


With the advancement in technology, new concepts in green technologies are emerging. This comes as a relief to the fact that global warming together with climate change are challenges that need to be worked on despite facing a lot of opposition and critics from those in denial. It is indisputable that the environment is degrading due to human neglect resulting from their continuous utilization of fossil fuels known to be not only non-renewable sources of energy, but also contribute significantly to the destruction of the ozone in addition to causing pollution. Nevertheless, some new technologies that have emerged with the aim of bringing in alternative sources of energy to salvage the environment are here.

Thermo- Depolarization

Thermo-depolarization is a process of manufacturing oil using wastes from carbon. This is achieved by employing enough heat together with high pressure on the waste. It is simply a replication of Mother Nature’s process of generating oil. However, in this case the process is done at a higher rate to yield the same product. Isn’t it outstanding how one can generate about 600 pounds of oil simply from a big junk of poultry bowels? It is one of the unique emerging green technologies advocating for environmental protection.


Hydrogen Fuel Cells

The hydrogen fuel cell is aimed to protect the environment by being an alternative source of energy. Water by is produced by combining two elements; oxygen and hydrogen. This is from basic chemistry. Since this reaction is exothermic, meaning heat energy is given out; this energy can be tapped and used to generate electricity. The major challenge that must be overcome in this technology is the sourcing of hydrogen used in the cells. One of the sources of hydrogen put forward is from water and even alcohol. However, to get the hydrogen from this sources, energy is required which must come from other sources. This creates the limitation of hydrogen cells leaving experts in the field of green technologies uncertain on the use of hydrogen as a source of fuel. This has also been an issue of contention on the utilization and economic viability of the hydrogen economy.

Ocean Thermal Energy Conversion

Water on the earth’s surface absorbs a lot of solar energy. This is because water is known to occupy more than 70 percent of the earth’s surface, oceans being the largest shareholder. Research has shown that the amount of solar energy absorbed by water in oceans alone is equivalent to the total energy stored in about 250 billion oil barrels in a single day. Ironically, the United States uses about 7.5 billion oil barrels in a single year. This shows the viability of this green technology technique in generating 33 times more energy per day from simply tapping the suns energy from the ocean waters. This is more than the entire products of petroleum that the United States consumes every year. This shows the strength and capability of tapping this form of energy.

The temperature difference between the surfaces of ocean water and that of water in the bottom of the ocean is what is harnessed in converting heat energy to electrical energy. The temperature difference exists because the surface of water is heated by the sun while water found at the bottom of the ocean is cooler. This technology is commonly referred to as ocean thermal energy conversion and usually abbreviated as OTEC. This technology has the limitation of not being very efficient in generating electricity at a fast rate.

There is a lot of debate on the existence and effect on climate change as well as global warming on the environment. Some people are still in denial that the use of fossil fuels is the biggest contributor to global warming, climate change and environmental degradation. Despite this state of affairs on global warming, green technologies continue to emerge and are being developed to help in addressing the issue. All this technological advancements and innovations are aimed at safeguarding the environment for future generations to survive and thrive. It is with the same spirit that this article elaborates, encourages and promotes the new emerging techniques aimed at creating new ideas on generation of alternative sources of renewable energy to safeguard the environment.
