By two months one gets tangible reduction in mosquito problem. This experience has repeated at many sites. Further research unearthed the reasons for the magnificent result produced in a short span of two months.
This can be easily extended to larger areas with people’s participation as well as cooperation & guidance from concerned agencies like the WHO and the perennial & apparently unsurmountable problems like Mosquito menace & Malaria, Dengue fever & a host of other problems can be solved once for all. See also Some history. This tall claim is based on the confidence given by the three decade long experience in the matter.

Sustainable energy is the provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainable energy sources are most often regarded as including all renewable energy sources, such as hydroelectricity, solar energy and power, wind power, wave power, geothermal energy and power, biomass fuel and energy, and tidal power. It usually also includes technologies that improve energy efficiency. While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development. As of 2011, small solar photovoltaic (PV) systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves. |
