In addition, the sticky silt and soil particles will also reduce the calorific value.<\/li>\n<li><strong>Cost of Power is high:<\/strong>\u00a0Generally, the tariff at which the power is purchased by to energy plants across the country is around \u20b97-8 KwH which is higher than the \u20b93-4 per KwH generated through coal and other means. This could be a serious challenge, as the selling price of power cannot be increased corresponding to the purchasing price.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Context:\u00a0Recently Karnataka Chief Minister B.S.
