Energy saving and emission reduction revolutionizing China's environmental protection

Great pressure to curb carbon emission and increased need for energy have forced China to develop an “energy saving and emission reduction” (ESER) plan. ESER has become China's basic national policy, and a guideline for China's energy and environmental issues during the 11th Five-Years Plan (2006–2010). ESER represents a recalibration of China's economic model, moving away from growth-at-all-cost in favor of a more “balanced and sustainable” output. In 2007, China's GDP grew by 11.4%, but emission of COD and SO₂ decreased by 3.14% and 4.66% respectively compared to 2006, energy consumption for each unit of GDP declined by 3.27% also compared to 2006. ESER is also the engine behind reform of China's traditional administrative system which has always favored economic growth over environmental protection. The ESER accountability system sets green efforts as a decisive factor in determining the career prospects of local leaders. Also, China's State Environmental Protection Agency has been upgraded to the Ministry of Environmental Protection, gaining cabinet status for the first time. A greener future relative to the previous three decades can be anticipated with confidence for China provided that the best practices enunciated by ESER are taken to heart by policymakers.

Experimental comparison of open sun drying and solar drying based on evacuated tube collector

In this article, an experimental comparison between open sun and solar drying is done. The thermal performance of evacuated tube based solar dryer is investigated with drying characteristics of Phyllanthus Emblica (Anvla), Aloe Vera, Aegle Marmelos (Bel) and leaves of Azadirachta Indica (Neem), Aegle Marmelos (Bel) and Psidium Guajava (Guava). In this setup, an evacuated tube collector, shell and tube heat exchanger and drying chamber are used. It was found that the maximum temperature difference between hot air and ambient air is 35.4°C and maximum efficiency of the setup is calculated as 55%. The average drying rate of Phyllanthus Emblica (Anvla), Aloe Vera and Aegle Marmelos (Bel) is measured as 0.46?g/min, 0.44?g/min, and 0.39?g/min respectively which are higher than that of Open Sun Drying. The leaves of Azadirachta Indica (Neem), Aegle Marmelos (Bel) and Psidium Guajava (Guava) also get dried with faster rates of 0.18?g/min, 0.17?g/min, and 0.14?g/min respectively.
