The document provides an overview of major renewable energy sources including solar, wind, biomass, waste to energy, geothermal, and hydroelectric power. It discusses the technology behind each energy source, growth trends in India, advantages and disadvantages, and leading companies. The future of renewable energy in India is promising with a goal of adding over 135 gigawatts of power generation capacity before 2017 through various renewable sources to meet increasing energy demands in a sustainable manner.

Solar Energy That will be explained in the succeeding slide
Technology Concentrated Solar Power (CSP) Photovoltaic (PV) It consists of It consists of Solar Collectors Turbine Solar Arrays Generator & Transformer Inverter Cooling Tower Transformer
Future Technology Solar-Hydrogen Revolution Usable Waste high-quality Heat energy Storage The and environment Solar light Transport Combustion Decomposition of water H Water Power 2H2 + O2 2H2O 2H2O 2H2 + O2 2 Vapor Plant
Advantages and Disadvantages Advantages Disadvantages Sun does not shine All chemical and radioactive polluting byproducts of the consistently. thermonuclear reactions remain behind on the sun, Solar energy is a diffuse while only pure radiant energy source. To harness it, we reaches the Earth. must concentrate it into an amount and form that we can use, such as heat Energy reaching the earth is and electricity incredible. By one calculation, 30 days of Addressed by approaching sunshine striking the Earth the problem through: have the energy equivalent of 1) collection, the total of all the planets 2) conversion, fossil fuels, both used and 3) storage. unused!
Global & India scenario Global growth of Solar Power State-wise Power Generation 1.2% 8% 1.5% 2.2% MW 20.2% 66.9% Installed Capacity (as of 2011) : 979.4 MW Year

Geothermal Energy That will be explained in the succeeding slide
Technology Average gradient: 2.5 - 3.0oC / 100m Variation: 1.0 - 25oC / 100m So if assuming average, temps at depth will be: 0m 15属C 2000 m 70属C 4000 m 120属C
Types of Geothermal Power Plants Dry steam Flash steam Binary steam
Interesting Facts about Geothermal Energy The Cerro Prieto Geothermal Power Station is the largest geothermal power station in the world. Geothermal production of energy is 3rd highest among renewable energies! In Iceland, Geothermal Energy provides 86% of their space heating 16% of their electricity generation Produces 5% of Californias electricity, heats thousands of homes, greenhouses, office buildings.
Positives and Not-so Positives Pros Cons Useful minerals, such as zinc and silica, can be extracted from underground water. Brine can salinate soil Geothermal plants do not require a Extracting large amounts of water can lot of land, 400m2 can produce a cause land subsidence, and this can lead gigawatt of energy over 30 years. to an increase in seismic activity Geothermal electric plants production in Can release H2S, the rotten eggs gas. 13.380 g of Carbon dioxide per kWh Geothermal plants can be online There is the fear of noise pollution 90%-100% of the time. during the drilling of wells
Direct Uses of Geothermal Energy Space Heating Melting Snow Drying Aquaculture Hot water Air Conditioning Industrial Processes Greenhouses Resorts and Pools
India Scenario Indian geothermal provinces have the capacity to produce 10,600 MW Exploration of Himalayan provinces could yield enormous geothermal energy India's fist Geothermal power plant with an initial capacity of 25 Megawatts will be coming up in Andhra Pradesh's Khammam district by 2012.
