“I have grown, looking at sky and stars.” Many people can say this, including me. We loved to watch stars in night. We enjoyed the Sunrise and Sunsets. And offcourse, millions of people loves NASA’s Astronomy Pic Of the Day and they like to add APOD as their wallpapers. There are many more beautiful phenomena in the universe, like Solar Eclipse, Eagle Nebula, Aurora etc. We feel safe, cheer and enjoy our life. However, it does not mean that a smaller strike of any tragedy cannot happen even as you are reading this blog. For a horrible example, who was knowing about the latest Tsunami in Japan, before the date it occured?
The theory of gravity is not enough developed that you can exactly state the motion of a planet or star or any other material in the space. Some bodies, like dwarf planets, sattelites, meteoroids, have random motions. The most fearful motion is of meteoroids, the rock like structures. Usually these are found in between Mars and Jupiter as a belt. But when a meteoroid leaves the belt, the gravitational attraction of the earth, nearest planet to mars, can pull that into it. When a meteoroid enters the atmosphere, friction causes it to heat up and glow. Then we call it a shooting star or a meteor. Small meteors burn up completely as they pass through the atmosphere. Larger ones end up on earth as meteoroid. Impact craters are formed when a large meteoroid or comet crashes into a planet. One such massive natural hazard happened in past, which destroyed all the Dinosaurs.
What is the ‘Need’ of this Clean Technology?
Why Not? There is a desperate need to meet the challenges caused by climate change and environmental degradation. In the past, it was the entrepreneurial spirit that contributed most to the innovations with far reaching benefits. Besides, scientists from outside the industry innovated technologies like steam power, the railways, telegraph, radios and telephone, petroleum, the automobile, computer, internet etc. etc. Yet the role of entrepreneurial innovation in addressing environmental problems has recieved relatively little attention. In this context, presently, the clean technologies have emerged.
Why is this Techology Clean?
Clean Technologies are technologies that use energy, water, raw materials and other inputs more efficiently and productively, create less waste or toxicity, deliver equal or superior performance, and improve customer profitability, through cost reduction and/or increased revenues. Such technologies are found in a broad range of industries, including energy, water, manufacturing, advanced materials and transportation.
Why We Should Use It?
With the decrease of available energy sources; like, petroleum, coal etc., demand for energy worldwide going through the roof and after poor effects of global warming, manufactures realise that alternatives are serious business.
Convergence of environmental, technological, economic and social factors will produce more resource-efficient technologies that will be less reliant on obsolete, polluting technologies.
Clean technology is an intrinsic part of a sustainable economy. Over the past few years, the importance of developing clean technologies has grown significantly and has driven the growth of what are now multi-billion dollar markets. Globally wind energy market was valued at $5 billion in the begining of 21st century, are expected to grow to $550 billion by next year, while solar energy is expected to note from $3.5 billion to $28 billion by the same timeperiod.
The measure share of the climate change in the outlook towards clean technologies has been due to the increasing realisation that this is not merely a social responsibility requirement, but also yield amazing profits.
The result of this awareness is steadily evolving into a sustainable new economy, which is based on premises of clean energy, transportation, water and materials that embody the emerging principles of industrial ecology, resource productivity and natural capitalism. Industrial houses, corporates, as well as goverments are now investing in research and developement on environment-friendly technologies.
There is a need in developing countries to have easy access to the technologies and cheaply. For any major change, changing political understanding on such issues, government support and prospects for business involvement is critical. For the advance of clean technologies require adequate and reliable R&D budgets, better incentive systems to promote and support clean-tech purchases by businesses and competitive price for consumers. A robust economy is as much required for encouraging clean tech investments. And That’s All.
