At present, in India, the total installed renewable power capacity is…

CONCEPT

India's Ministry of New and Renewable Energy (MNRE) and the Central Electricity Authority (CEA) report “total installed renewable power capacity” as a specific accounting category. It counts only those renewable-energy technologies that have reached commissioned, grid-connected scale in the country — a source can be renewable in the general scientific sense yet still be excluded from this count if no commissioned plant of that kind exists in India.

APPLICATION

Checking each source named in the stem against this official category: Solar Power, Wind Power and Hydropower are long-established, large-scale contributors to India's grid. Urban and industrial waste-to-energy conversion and Biomass power (including bagasse cogeneration) are also separately tracked, commissioned categories in MNRE and CEA reports. Geothermal power, however, has no commissioned, grid-connected plant anywhere in India — the country's geothermal potential remains at the survey and pilot-project stage, so it does not add to the installed-capacity figure. That leaves five sources — Solar, Wind, Hydropower, Waste-to-energy conversion and Biomass power — as the ones actually accounted for.

CONTRAST

• “Only (a), (b), (c), (e) and (f)” leaves out waste-to-energy conversion, which IS a separately tracked, commissioned category, while including geothermal power, which has no commissioned plant in India.

• “Only (a), (b), (c), (d) and (f)” leaves out biomass power — a large, well-established category that includes bagasse cogeneration — while still including geothermal power.

• “(a), (b), (c), (d), (e) and (f)” — the complete list of six — over-counts by treating geothermal power as already installed, when India's geothermal potential remains only at the survey and pilot-project stage.

Result: the five sources with commissioned, grid-connected capacity in India — Solar Power, Wind Power, Hydropower, Urban/industrial waste-to-energy conversion, and Biomass power — are exactly “Only (a), (b), (c), (d) and (e)”, matching the saved key. This is confirmed by MNRE's Physical Progress report and the Central Electricity Authority's Installed Capacity Report, both of which list these five as the tracked renewable categories, with no commissioned geothermal capacity in India.
