“…Renewable energy sources are considered the way to unlock energy transition positively affecting the National Power Grid performance [1] by supplying natural driven energy such as solar, wind and marine [2]. Among marine resources, ocean waves are one of the most promising sources of renewable energy with an estimated potential of 2 TW around the world [3].…”

Study of a hydraulic system converting energy from sea waves near the coast

This paper proposes a system able to recover energy from sea waves. The system is made up essentially of a floating structure, connected to a piston pump. The pump, constrained to move vertically under the action of the waves, pushes water into a reservoir maintained at constant pressure, from which it flows in a Pelton turbine. A methodology was developed for the preliminary sizing of the proposed system. This methodology takes the height of the waves and the pressure of the reservoir as reference parameters and then provides the main geometric data of the machines. A case study developed in the present work, demonstrates the possibility of designing miniaturized components of the system, able anyway to provide acceptable energy output with contained installation costs.

“…As a result, the average CO 2 emissions factor is much higher than that in other country. In Italy, CO 2 emissions factor in 2017 is approximately 346 g/kWh, while the CO 2 emissions factor is approximately 870 g/kWh in China [53,55]. The 5 studied cities by sub-regions of the national grid and the CO 2 emissions factors of the sub-regions are presented in Figure 9.…”

Many stadiums will be built in China in the next few decades due to increasing public interest in physical exercise and the incentive policies issued by the government under its National Fitness Program. This paper investigates the energy saving and carbon reduction performance of timber stadiums in China in comparison with stadiums constructed using conventional building materials, based on both life cycle energy assessment (LCEA) and life cycle carbon assessment (LCCA). The authors select five representative cities in five climate zones in China as the simulation environment, simulate energy use in the operation phase of stadiums constructed from reinforced concrete (RC) and timber, and compare the RC and timber stadiums in terms of their life cycle energy consumption and carbon emissions. The LCEA results reveal that the energy saving potential afforded by timber stadiums is 11.05%, 12.14%, 8.15%, 4.61% and 4.62% lower than those of RC buildings in "severely cold," "cold," "hot summer, cold winter," "hot summer, warm winter," and "temperate" regions, respectively. The LCCA results demonstrate that the carbon emissions of timber stadiums are 15.85%, 15.86%, 18.88%, 19.22% and 22.47% lower than those of RC buildings for the regions above, respectively. This demonstrates that in China, timber stadiums have better energy conservation and carbon reduction potential than RC stadiums, based on life cycle assessment. Thus, policy makers are advised to encourage the promotion of timber stadiums in China to achieve the goal of sustainable energy development for public buildings.Sustainability 2020, 12, 1566 2 of 24 carbon dioxide (CO 2 ) [4]. The use of fossil fuels is believed to be the main factor leading to global warming [5,6]. Global warming is widely considered to cause glacier retreat and regional climate changes, species extinction, and further uncertain risks [7,8].Measuring the "greenhouse effect" for mitigation purposes has become a major interest internationally in the last few decades. During the last 50 years, global warming has mainly been caused by excessive GHG emissions due to human activities [9]. International Energy Outlook (2019) reported that the building sector, one of the most important areas of human activities, accounted for 20% of the world's delivered energy consumption in 2018 [10]. This figure will rise to about 22% by 2050 [10]. The Brown to Green Report (2019) showed that carbon emissions directly from the building sector accounted for 9% of G20 energy-related CO 2 emissions in 2019 and that 18% of these emissions arose from electricity use in buildings [11].At the end of 2016, the energy consumption of buildings in China was 26 billion GJ, accounting for 20.6% of the country's total energy consumption. In total, the building industry emitted 1.96 billion tons of CO 2 in this year, accounting for 19.4% of domestic carbon emissions [12]. At the 2015 United Nations Climate Change Conference [13], the Chinese government set the goal of reducing carbon emissions per unit of GDP by 60%-65% by...

Collective manure processing facilities to reduce nutrient loads and produce renewable energy are often proposed as feasible solutions in intensive livestock production areas. However, the transferring of effluents from farms to the treatment plant and back to farms, as well as the treatment operations themselves, must be carefully evaluated to assure the environmental sustainability of the solution. This study evaluated the global warming potential (GWP) and acidification potential (AP) of a collective treatment plant for bioenergy production and nitrogen removal as an alternative strategy to conventional on-farm manure management systems. Two manure management scenarios were compared: manure management on individual farms and management by a collective treatment plant. Data were collected at a collective processing plant and at the individual farms of the consortium to estimate emissions of CO2, CH4, N2O, NOx, NH3 and SO2. The plant receives manure from 21 livestock production units, treating 660 tonnes day−1 of manure. The GWP and AP indicators were calculated to evaluate the potential impact of the two management solutions. The collective solution reduced both GWP (−52%) and AP (−43%) compared to manure management separately by each farm. Further improvement might be obtained in both indicators by introducing mitigation techniques in farm manure storage and manure application to soil.
