Algae are considered the most promising third-generation biofuel feedstock, because algae can grow on wasteland, wastewater, and waste gas. Thus, they do not compete with any resources needed for other useful purposes. Understanding how to engineer algae-to-biofuel systems is critical if we have to succeed in meeting our future transportation fuel demands. This chapter presents the engineering fundamentals of the algae-to-biofuel process and also draws attention to the challenges we must overcome.

Assessment of, and mapping the extent of forest fragmentation is one of the key requirements for undertaking any eco-restoration work. Using a moving window approach on high-resolution geospatial data on vegetation, a fragmentation index was computed across the entire Indian landscape. On the basis of the index, the forests areas were categorized as high, moderate, low or intact. It was observed that almost half of the forested land is intact in spite of tremendous population pressures, indicating effective protection.
Experimental study for energy efficient cooking devices based on solid biomass fuel and its sustainability for rural India

Biomass fuelled cooking in traditional mud stoves is a widespread phenomenon especially across rural India.
Expanding Rural Energy Access and Improving Agro Industrial Energy Efficiency through Targeted Interventions
While access to low-cost, clean, safe, modern and sustainable energy technologies is a priority to farmers and agro-communities residing in villages, improving energy efficiency as a cost cutting measure is extremely important to rural agro industries, especially micro, small and medium enterprises (MSMEs). Hence specific and targeted projects focusing on building awareness at the grass-root level, technology transfer, capacity building and fast-tracking clean energy financing to these sector are crucial growth and development drivers.

REDD+ is a financial instrument to incentivize conservation and sustainable management of forests, and thereby achieve reduction in the GHG emissions resulting from deforestation and forest degradation. It aims at compensating forest owners in developing countries for conserving their forests by putting a value on the forest carbon stocks - one of the many ecosystem services that forests provide. This chapter aims at discussing this path of evolution and the current state of affairs with the REDD+ mechanism.

Digital Elevation Model (DEM) is a quantitative representation of terrain and is important for Earth science and hydrological applications. DEM can be generated using photogrammetry, interferometry, ground and laser surveying and other techniques. Some of the DEMs such as ASTER, SRTM, and GTOPO 30 are freely available open source products. Each DEM contains intrinsic errors due to primary data acquisition technology and processing methodology in relation with a particular terrain and land cover type. The accuracy of these datasets is often unknown and is non-uniform within each dataset.
Evaluation of bio efficacy of Tylophora indica leaf extracts, fractions and pure alkaloids against Helicoverpa armigera (Hubner)
Kathuria V, Ruhl S, Kaushik N, Edrada-Ebel R, Proksch P
Crude extracts, fractions and pure alkaloids from Tylophora indica (Burm. f.) Merrill were tested against Helicoverpa armigera larvae and moths. Among the extracts, ethanol extract was more effective than the hexane extract in reducing larval growth with GI50 value (concentration at which 50% reduction in larval weight obtained) of 0.031. Significant reduction in pupal weight was also observed (up to 20%).

To accelerate the decarburization in the Indian power sector, concentrating solar power (CSP) needs to play an important role. CSP technologies have found significant space in the Jawaharlal Nehru National Solar Mission (JNNSM) of the Indian government in which 20,000 MW grid connected solar power projects have been targeted by 2022 with 50% capacity for CSP.

Smart Electric Grid is an important as well as intelligent element towards the development of an energy independent and environmentally sustainable society. Although there is no universal definition for Smart Grid, it has various functionalities towards modernization of the electrical grid by using digital systems and addressing disturbances via automated prevention and various other novel ideas. But a smarter grid needs a real-time analysis of the network.
