GREEN ELECTRICITY: THE FUTURE
No issue demands the attention global community than concerns about global warming, climatic changes, high incidence of and high incidence of CO2 emissions. Environmental activists, energy entrepreneurs, consumers, regional and national governments have all been clamouring for global actions that threaten the human existence and healthy living. It is a fact that due to flagrant economic activities, technological advancement, and human settlement and so on, humans have inevitably tampered with nature and are gradually creating a noxious environment. The prevalence of cancerous skin diseases, climatic disorders, and other negative occurrences damaging biotic living in the ecosystem has generated a clarion call to protect our environment.
The need for power generation globally to meet the burgeoning demand in electricity cannot be overemphasized. Technological sophistications, consumer electronics, industrialization and hi- tech market all need adequate power for functionality. Carbondioxide emissions have been highly touted as the major element causing greenhouse effect and global warming. Clear findings have shown that pragmatic efforts are being enabled worldwide to reduce fossil fuel technology such as coal, gas, oil and so on through carbon sequestration methods and adopt the renewable technology which has little or no negative effect on our immediate environment.
A peep into present shows that actions are being tailored to reduce power consumption among devices. The automobile industry is highly investing in the Lithium ion battery for reducing power consumption. High level of research is being conducted to reduce power consumption at the telecomms infrastructure especially the amplifier which consumes 60% of cellular base stations power. Devices from Nujira known as High Tracking Accuracy Modulators are being used to design efficient, smaller and cheaper base stations. Most leading companies such as Vodafone UK are targeting improvement in energy efficiency of new network equipment. Ericsson R&D are developing a prime technology to reduce carbondioxide emissions by 25% as they are developing tower tubes for reduction of power consumption by 15-25% .Inactive timeslots on the transmitters are shut down to reduce power consumption through a software that monitors unused timeslots in a cells. These are pragmatic efforts to reduce
carbondioxide emissions from the ICT sector which is touted to contribute 1.2% to global warming.
Renewable energy is also been encouraged and highly researched with various models coming out in order to reduce the carbondioxide emissions. Water power is seriously considered to be the leading technology with use of tidal currents to drive turbines and wave technology. Solar energy is been used for small scale units or low power consumption appliances and solar energy research improvement is being encouraged. Wind power is also of high development with accurate statistics on wind speed and expansion of the wind energy technology has been the toast of environmental groups for a larger percentage of renewable sources in the energy mix. Many ‘green’ experts have analyzed inconsistent oil and gas prices in international market can be gradually outdone with the sharp development of wind power and other renewables.
Moreover other technological sources for power generating stations are being powered which is the use of
carbon-gas pressure rather than combusting gaseous fuel technology for driving turbines, osmotic pressure between saline and fresh water bodies and also electrolytic separation of water into hydrogen which is converted back into electricity using fuel cells. The Hopewell Project in US is supporting renewable energy which uses solar energy acts as primary source of energy and hydrogen energy is stored in tanks to supply in times low solar intensity.
It is obvious that the green movement is already influencing the world. Carbon combustion rating of power generation vendors is being analyzed while tags are being placed on utility bills to show source of power supplies. Most energy companies are striving to be branded as ‘green’ as this will have as an effect on the consumer demand in the nearest future. Consumers are growing environmentally responsible and they are demanding cheap, reliable and low-carbon energy. Power consumption companies such as Centrica are deploying low-carbon mix to enhance a strong brand marketing while the slogan of British energy is ‘to power low carbon generation’. Carbon capture technologies have being linked to coal generation stations and the EU is making concerted efforts to ensure a full carbon-captured European market by 2020 where 20% of energy is generated from renewables. The European Union and national governments in Europe are adopting policies and concessions to influence an energy market with a low-carbon outlook. I strongly believe developing and third world countries with become also green conscious in the future to come.
It is noteworthy that nuclear generation is also being seriously considered across territories despite controversies about nuclear weaponry undertones and the problems of nuclear waste management. A hybrid approach of various renewables-biomass solutions, fuel and water pressure, biogas, liquid biofuels and nuclear energy represents the future and even other slight escape of other severe environmental destructive gases of SF6 are being monitored and ensuring optimum global safety even in protection of electrical infrastructure. Even though renewables have not been economically competitive and highly subsidized for production, adequate research will help to build profitable solutions.
The open truth is that the world is at war with environmental destructive activities as all efforts are geared to create a healthy globe. G8 countries are lending a common voice at their summit to stem carbon emissions and inculcate the green initiative to all stakeholders. The future is green and you need to be environmental responsible either as a consumer, vendor, government, power suppliers or whatever to stay relevant. Electricity goes green, the world becomes safer.
