India as a developing economic power, has to rely much on its energy sector for growth and development. The growth is largely interlinked with the availability of energy and its judicious utilization. Also involved is the question whether the available energy is environmentally acceptable and technically viable. With the growth of country's economy, per capita power consumption has also increased resulting greater demands for power. India's power sector is mainly dependent on conventional or fossil fuels i.e., coal (60.1%) and gas (8.7%) (2015). India has around 10% of the world's coal reserves that will last for about another 30–40 years at the present consumption rate. The use of conventional fossil fuels has a negative impact on the environment due to the emission of harmful greenhouse gases. On the other hand, according to the Ministry of New and Renewable Energy (MNRE), Government of India, the country has untapped source of renewable energies such as, wind, solar power, nuclear energy and biomass. Globally, depletion of conventional fuel resources, is increasingly turning the focus on non-conventional sources of energy. The present paper is a review of biomass energy, its sources and its energy efficiency. Even though sources of biomass fuels are widely available all across India, these are still largely underutilized. According to the available statistics, in India the share of renewable energy has increased from 7.8% to 12.3% during 2012-13 and to 12.95% as on 31st March 2014, this paper also highlights the challenges and advantages of biomass energy over conventional fuels as well as utilization and applicability of biomass in sintering process as a replacement for coke.

The aim of this research is to examine the link between CO 2 emissions, hydroelectricity consumption, urbanisation and real GDP in China and India during the period of 1965–2013. The long-run cointegration is investigated by the autoregressive distributed lag (ARDL) bounds testing approach, which is augmented with structural breaks. We employ the ARDL cointegration test to establish long run relationship in the variables. Furthermore, we use the ARDL to show that real GDP and urbanisation have long-run positive impact on emission, while hydroelectricity consumption exerts long-run negative impact on emission in both countries. The results support the existence of environmental Kuznets curve (EKC) hypothesis in China and India. Besides, the paper assesses the causal link between the variables by using Granger causality procedures and the results show that there is long-run bidirectional relationship between the variables in both countries.
