Integration of intermittent renewable energy resources onto the power grid provides a means of achieving green-energy supply. Solar power generation poses significant integration challenges due to its nature of intermittency which affects the grid reliability and stability with reference to voltage profile and quality of the grid power. Electrical network reliability is the ability of the power grid to deliver load demand without failure while maintaining the system's constrains. Sizing and siting of solar photovoltaic should be optimized for maximum utilization in a power distribution network........

Hydrothermal processing is suitable process for feedstock with high moisture content, such as manure, sewage sludge, food waste, municipal wastes, forest waste, plants and aquatic biomass as micro- and macro-algae. The results of hydrothermal processing are residual solid, soluble liquid and gases products. Liquid product is called bio-crude or bio-oil as a fuel raw materials..The residual solid has high carbon content as a solid fuel and gases products mostly contain a mixture of H2, CO2, CO, CH4. The hydrothermal carbonization (HTC) resulted higher residual solid. By another treatment solid carbon can be used in many application, such as adsorbent, capacitor, batteries, and energy storage. Hydrothermal liquefaction (HTL) resulted higher soluble liquid.Upgrading of bio-oil made the bio-oil as fuel grade, and hydrothermal gasification (HTC) resulted a higher syngas products. Biomass with high moisture content that have lower energy content can be converted into three phasesthat have high energy content.

Key Words: hydrothermal, solid, liquid, gases, product.

Amidst the evolving dynamics of social change and globalization, university students, as a crucial demographic, confront mounting psychological pressures and trials. This study zeroes in on university students in Sichuan Province's Chengdu region, probing the nexus of happiness, psychological health, and social fairness.

Green Economy means green economy. This is the only way in which we can preserve our environment along with necessary development. Green Economy is about significantly reducing environmental hazards and ecological scarcity while improving public welfare and social participation. Invest in methods and products that promote it maintaining social equality while removing threats to the environment and ecological deficiencies is called green economy. Public and Private investment should take care to minimize carbon emissions and pollution increase energy and resource efficiency and help prevent damage to biodiversity and the environment.

Key Words: Challengers, possibilities, sustainable development.
