Geothermal Energy Source https://c03.apogee.net/mvc/home/hes/land/el?spc=kids&id=1 6216&utilityname=demo • Geothermal energy is clean energy, because no fuel is burned. • Geothermal power plants use steam from wells that reach deep in the earth into geothermal reservoirs. • These reservoirs are usually found along the earth's major plate boundaries, where volcanoes and earthquakes occur most frequently. • Since there are no physical signs above ground for geothermal reservoirs, geologists must drill a well and test the temperature of the ground to see if there is a reservoir that can be used.
- 3. Geothermal Energy Source • There are three types of geothermal energy used to make electricity: Hydrothermal - Uses steam and hot water. Geopressured - Uses hot water (around 350 degrees Fahrenheit) and hydraulic turbines. Petro thermal - Uses dry hot rocks requiring water injections to make steam. • The most widely used process is hydrothermal, where steam is pumped from wells directly from the reservoir to a giant turbine. https://c03.apogee.net/mvc/home/hes/land/el?spc=kids&id=1 6216&utilityname=demo

Geothermal Energy Source https://www.tutorialspoint.com/general _knowledge/general_knowledge_geothe rmal_power_plants_in_india.htm The potential capacity is more than 10,000 MW in India. Son-Narmada-Tapi (SONATA) According to news in economic times on 17th Feb 2013, Chhattisgarh government has decided to establish the first Geothermal Power Plant of the country in the newly formed Balrampur district of the state
- 6. Biomass Energy • Biomass energy comprises different forms of usable energy obtained from materials referred to as biomass. A biomass is a biological material in solid, liquid or gaseous form that has stored sunlight in the form of chemical energy. • By burning bark, wood chips, sawdust and “pulp liquor” (a mixture of pulping chemicals and organic material), saw mills and pulp and paper plants create heat for drying kilns and produce steam and electricity to meet their needs or to sell to the grid. https://www.pmmer.com/technical-guide/biomass- energy-in-canada.html
- 7. Biomass Energy The leading states for biomass power projects are Maharashtra, Uttar Pradesh and Karnataka each one having more than 1 GW of Grid interacted biomass power. Other states with favorable policy and opportunities in Biomass are Punjab and Bihar. https://indien.um.dk/en/innovation/sector- updates/renewable-energy/biomass-energy-in-india/
- 8. First Integrated Geothermal and Biomass Plant in the World Enel Green Power has announced the completion of a 5 megawatt (MW) biomass power plant in Italy’s Tuscany region that integrates biomass with geothermal steam generation. https://www.renewableenergyworld.com/2015/08/03/world-s-first-integrated-geothermal-and-biomass- plant-goes-online/#gref It is projected that the integration of the biomass plant will boost the overall Cornia 2 geothermal plant output by some 30 gigawatt hours (GWh) a year. It will also mitigate the emission of 13,000 tonnes of CO2 annually.
