Water resources

Solar energy, light and heat radiation from the Sun, has been exploited by humans since ancient times using a variety of technology development than ever before. Solar radiation along with secondary resources of energy like wind and solar energy, water power and biomass, make the most of renewable energy available on earth. Only a tiny fraction of the available solar energy is used.

Lentic systems are a diverse set of inland freshwater habitats (Lakes and ponds) exist across the globe and provide essential resources and habitats for both terrestrial and aquatic organisms. The current work was intended to evaluate the quality of the selected ponds (Pond 1, 2 and 3) in and around Vellore district, TamilNadu. The water samples were collected to determine the physical and chemical parameters during every month in the year 2019. Water parameters such as temperature, pH, dissolved oxygen, Alkalinity, electrical conductivity, Chloride, Sulphate, Nitrate, Ca, Cl was studied.

The rapid economic growth in Vietnam has resulted in an increasing demand for electricity. This in turn translates to a higher rate of coal resource extraction and consequent rise in pollution of water and land resources. This study estimated the environmental costs associated with the electricity demand requirements of the coal electricity sector, as a component of the long-run marginal opportunity cost (LR-MOC) of electricity production.
