Technology was invented with the sole aim of providing a helping hand to the human kind. But, somewhere during the whole process, human beings became so much self-involved that they lost track of other important things like the environment that the technology could help them with. Fortunately, some percentage of human race did take note of the situation and decided to change it by coming up with clean technology or cleantech.
For people unaware about Cleantech, it mostly includes recycling renewable energy such as solar power, biomass, wind power and biofuels etc. These technologies are known to be competitive in quality when compared to the conventional technologies.
