Of all the rain that falls on the land and mountains and forests, some evaporates back in to the atmosphere, some is percolates in the ground and some is used by the forests. The remaining that flows in to the rivers is less than 50% on the total precipitation. The total annual flow in the rivers is estimated as 1869 km3.

On a global basis, it is estimated that renewable energy accounted for 12.9% of the total 492 EJ of primary energy supply in 2008 (IEA, 2010a). The largest renewable energy contributor was biomass (10.2%), with the majority (roughly 60%) of the biomass fuel used in traditional cooking and heating applications in developing countries but with rapidly increasing use of modern biomass as well. Hydropower represented 2.3%, whereas other renewable energy sources accounted for 0.4%.

More than 65% of India's electricity generation capacity comes from thermal power plants, with about 85% of the country's thermal power generation being coal-based. The 10 biggest thermal power stations operating in India are all coal-fired, with seven of them owned and operated by state-run National Thermal Power Corporation.

This map depicts the area under organic farming in different states of India. The area values are shown in hectares unit. Madhya Pradesh shows the highest value (2582439.75 hectares) whereas Manipur shows the lowest (11.25 hectares) for organic farming. It can be observed that North-Eastern states along with West Bengal shows the lower value for area covered under organic farming as compared to other states of India.

This map depicts the biomass energy potential (in Megawatt electrical) for different states of India. Rajasthan has the highest biomass energy potential i.e, 4595.0 MWe, whereas Meghalaya shows the lowest value of 1.1 MWe. It can be observed that the West Indian states show the higher biomass energy potential as compared to any other region in India.

This map depicts the number of Severe/Acute Malnourished (SAM) children in different states of India as on October 2013. Bihar state shows the maximum number of SAM children in India (1233860) followed by Uttar Pradesh (1212912), whereas Sikkim have least number (1613) on the table.

The map shows the estimated different types of renewable energy potential in Gujarat (2013). The data includes the wind power, small hydro power and biomass power potential. Out of these three wind power potential has the biggest share in the state.

The map shows statewise estimated installed capacity of wind power in India for 2014. Tamil Nadu and Maharashtra are the leading states in installed capacity of wind power.

The map shows statewise estimated wind energy potential in India. Gujarat has the highest wind potential in India followed by Andhra Pradesh.

The map shows the technology interventions under TERI's Improved Cookstove Initiative in different states of India. The data is up to September 2014.

The map shows the statewise length of total roads in India. Maharasthra and Uttar Pradesh have highest road network whereas Sikkim has lowest road network among all the states.

Maharashtra is the leading state in municipal solid waste generation having waste generation of 19204 MT/day. West Bengal and Tamil Naidu are the states which generate more than 12000 MT waste per day.

The map shows the mean annual rainfall in states of India from 1901 to 2000. The data has taken one mean value for all the union territories. The north eastern states has received the highest rainfall annually in last 100 years.

The level of registration, defined as the percentage of registered births/deaths to the births/deaths estimated through SRS (Sample Registration System), determines the performance level of a State / Union territory in respect of registration of births and deaths.Map shows that 14 States/UTs namely Arunachal Pradesh, Assam, Goa, Gujarat, Himachal Pradesh, Kerala, Maharashtra, Meghalaya, Mizoram, Nagaland, Punjab, Chandigarh, Delhi and Puducherry have recorded cent percent registration of births in 2010.

The figure shows the trend of number of registered births and deaths in India. The trend of birth rate is increasing very fast as compared to death rate in country. The difference between number of registered births and deaths is huge and is increasing every year.

The map shows the statistics of production of bio-medical waste from the states. The unit is kg/day. Karnataka tops the list whereas the UTs (Lakshadweep, Daman & Diu) are minor producers.

The geographic distribution of the estimated potential of renewable power as on 31 March 2013 reveals that Karnataka has the highest share of about 15.37% (14,464 MW), followed by Gujarat with 13.27% share (12,494 MW) and Maharashtra with 10.26% share (9657 MW), mainly on account of wind power potential.

There is high potential for generation of renewable energy from various sources- wind, solar, biomass, small hydro and cogeneration bagasse. The total potential for renewable power generation in the country as on 31 March 2013 is estimated at 94,125 MW.

The map shows total of 20 refineries in the country, 17 in the Public Sector and 3 in the private sector as on 31.03.12. Public sector refineries are located at Guwahati, Barauni, Koyali, Haldia, Mathura, Digboi, Panipat, Vishakhapatnam, Chennai, Nagapatinam, Kochi, Bongaigaon, Numaligarh, Mangalore, Tatipaka, and two refineries in Mumbai. The private sector refineries built by Reliance Petroleum Ltd and Essar Oil in Jamnagar and Vadinar respectively.Total installed crude oil refining capacity in the country at the end of March 2012 was around 198 million tonnes per annum.

For economic as well as environmental reasons, India needs to shift to non-polluting renewable sources of energy to meet future demand for electricity. India has a vast supply of renewable energy resources, and it has one of the largest programmes in the world for deploying renewable energy products and systems.
