Summary: The study evaluates and compares the environmental and energy performance of direct gasification and combustion using residual forest biomass in Portugal. Gasification performs environmentally better than combustion in most impact categories, but combustion has a higher Energy-Returned-On-Energy-Invested ratio. The study concludes that gasification may be a good alternative to current combustion systems in Portugal.

Summary: This study assessed 239 farm year observations of Swiss farms to analyze the relationship between environmental and economic performance and correlations between product groups. There were no trade-offs between environmental efficiency and economic performance, and synergies were found in some product groups. Organic farming systems performed better in terms of both environmental and economic efficiency. However, the mountain region had lower environmental performance and productivity.

Summary: Wind power, especially onshore wind farms, has been widely used globally. A study conducted on a newly built 40MW wind farm in China with consideration of infrastructure showed that the greenhouse gas emissions intensity was slightly higher compared to nuclear and hydropower, almost comparable to photovoltaic power, yet significantly lower than thermal power and biomass power. Life cycle cost analysis indicated that the levelized cost of electricity from wind power was relatively low at around 0.01-0.02 USD/kWh.

Summary: Household carbon emissions in the US are significantly influenced by income levels, with higher income groups having much higher carbon footprints compared to lower income groups. Consumption patterns and household size also play a role in affecting carbon emissions. The US has a high average per capita carbon footprint due to factors such as reliance on private transport and heating and cooling emissions.

Summary: Exploring the emission characteristics of vehicle pollutants is crucial for preventing and controlling the spread of pollutants. Due to geographical and economic limitations, model- and guideline-based studies on vehicle emission factors have become more popular than actual measurements. This study analyzed the actual operating conditions of motor vehicles and obtained the emission factors of typical pollutants from different vehicles using the international vehicle emission (IVE) model and guideline method. The resulting emission factors were compared and analyzed with on-road measurements. The study found that the emission factors of vehicle pollutants change regularly with velocity, emission standard, and accumulated mileage. The IVE model was found to be close to the actual measurements, while the guideline method had a larger error.

Summary: This study analyzed the impact of U.S. household consumption on greenhouse gas emissions, finding that changes in household consumption accounted for approximately one-third of the national emission decline. High-income households were the main contributors to emission increase before 2010, while the third and fourth income quintiles became emission mitigation leaders after that. The study also highlighted carbon inequality within high-income households and the need to focus on leisure-related services and goods for future emission reduction policies.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
