But it is also true that wind energy suffers from various challenges related to its sustainability as important energy source. Some of the important barriers are manufacturing cost, environmental factors, site specific, Low energy production etc. Conventional wind turbines were designed to be large in size so that they have power to turn turbine to produce sufficient power which in turn create difficulties in transportation and installation of wind turbine. Therefore there is need to develop such technology which can overcome above difficulties by using lightweight materials and low cost materials. Thus nanoscale models developed prolong the overall life of wind turbines by mitigating the fatigue failures of structural components and reducing the overall cost of power generation. Nanoscale technology introduced into wind industry contributes in bringing new development for wind turbines performance, operability, availability and reliability.

Solar photovoltaic technology is an efficient option to generate electricity from solar energy and mitigate climate change. Although the development and growth of solar photovoltaics has had a positive impact on energy system decarbonization, but end-of-life solar panels might become toxic waste if not properly disposed of. Presently in India, approximately 200,000 tonnes of solar photovoltaic waste are expected to be produced by 2030 and 1.8 million tonnes by 2050, by which time solar waste could grow to 60 million tonnes globally. Solar waste has recently been included in the category of waste electrical and electronic equipment to restrict the negative influence of continual development. Recent advancements have been focused only on increasing the efficiency of solar photovoltaic panels without considering the impact of waste solar panels on the environment and the issue of app...

This review presents the attenuative impacts of atmospheric aerosols, as well as reflectivity losses due to soiling of solar reflectors, by covering both experimental investigations and numerical studies; along with presenting the theoretical background. The chemical nature of aerosols, and the physics of soiling and atmospheric extinction phenomena (scattering and absorption) are also reviewed. Suspended particles like aerosols result in atmospheric extinction of the solar radiation that reaches the concentrators, and the deposition of these particles on the solar reflectors provokes decreases up to 80% in their reflectivity, and thus enhances the cumulus of optical losses and the reduction of energy production. Even though dust affects both CSP and photovoltaics, CSP technologies suffer more losses. The impact of dust should be particularly considered during ...

The effects of biochar on biogas production using different mass concentrations of biochar with cattle dung for hydraulic retention time (HRT) 60 days were evaluated. In comparison to a controlled treatment, adding 10 g/L of biochar per kg of cattle dung increases methane content, and biogas yield by 35.17% and 21.53%, respectively. Experimental results confirmed the use of biochar as a catalyst in biomethanation process. Hence, using 1 ton of biochar as a catalyst for generating 2000 m3 of biogas on a large scale will give significant results. This large amount of biochar will not only help in managing 3.3 tons of surplus crop residue but also produces 100 tons of digested slurry, which can help in saving 6.5 ton CO2 equivalent and 99,243.5 MJ of energy if it replaces the equivalent inorganic fertilizer. Further, it will reduce global warming potential (GWP) to 2.125 tons CO2. Biochar ...
