Solar energy may be used to treat waste water without chemicals or electricity. There is a further environmental advantage that algae grow in such ponds and consume carbon dioxide although algae may create hazardous compounds that make the water unusable.
Solar energy can be stored at high temperatures. Salts are a powerful storage medium because they can produce heat at temperatures compatible with conventional power systems, have a high specific heat capacity and are low cost. The Solar Two used this method of energy storage, letting it keep 4460; TJ in its 6860; m3 storage tank with a yearly storage efficiency of about 99%.
Solar energy60;- radiant light and heat from the sun. It’s been used by people since ancient times using a range of technologies that were ever developing. Solar energy technologies include solar heating, solar photovoltaics, solar structure and solar thermal electricity, which can make significant contributions to solving some of the most urgent problems the world faces.
Solar Energy is a sustainable form of energy and tends to give substantial number of energy and light to us. Petroleum, on the other hand also degrades the environment and is just not renewable. Continue reading
