Summary: Off-shore wind energy in Europe plays a crucial role in the transition to renewable energy and is expected to increase in the future. This study aims to estimate the behavior of extreme winds in Europe and their impact on off-shore wind energy availability. The findings indicate significant changes in the frequency of extreme wind events, suggesting the influence of climate change or long-term climate variability. The analysis also reveals that high and low extreme wind events can occur simultaneously in Europe, highlighting the need for efficient energy management policies.

Summary: This paper examines the sectoral patterns of job creation and destruction in a two-sector economy, distinguishing between the effects of embodied and disembodied technological change. The study finds that while both types of technological change have positive impacts on employment dynamics in certain sectors, the effects are not statistically significant. On the other hand, replacing obsolete capital tends to have a highly significant negative impact on labor demand.

Summary: Through analyzing the exogenous spatial and time variations in job creation tax credits across Georgia's 159 counties over a 15-year period, three empirical approaches were employed to estimate the causal effects on employment. The mixed results obtained do not provide strong evidence in support of the proposition that job creation tax credits create additional employment.

Summary: The integrated generator-rectifier architecture improves the power density, efficiency, and reliability of electric drivetrains in wind turbines. A design methodology for a 10-MW generator is presented, which includes a low-reactance generator and phase shifts between multiple passive ports to improve drivetrain reliability. The design uses a slotless permanent magnet generator and Halbach PM-array structure to minimize reactance. Co-simulation shows that the proposed architecture is suitable for offshore wind generators. A subscale generator is tested to verify the design.

Summary: A novel three-bifurcated mooring system is proposed for controlling the vibration of Spar-type floating wind turbines, which adds three-bifurcated sub-mooring lines to the original mooring system and uses more fairleads theoretically resulting in higher torsional stiffness. A clump mass is attached for further improvement. Experimental results show that the proposed mooring system can reduce wind turbine surge movement by up to 37.15% and yaw movement by up to 40% under regular and irregular waves.

Summary: This paper investigates the conversion of a Nordic oil-heated townhouse into a carbon-neutral building by implementing energy efficiency improvements and an off-grid system with solar photovoltaics, wind power, and battery and hydrogen energy storage systems. The study uses MATLAB and Microsoft Excel to determine the dimensioning of a heat-pump-based heating system and an off-grid electrical system, based on life cycle costs (LCC). The results show that energy efficiency improvements and waste heat recovery from the hydrogen energy storage system have a positive impact on the dimensioning of the off-grid system, reducing the LCC by up to 2 million euros. Wind power is found to be highly relevant in Nordic conditions, reducing the LCC by 32%.

Summary: Liquid air energy storage is an advanced technology that overcomes the geographical limitations of other utility-scale energy storage options. By combining the liquid air storage system with renewable energies and heat recovery units, it can address grid instability and low round trip efficiency. The study shows that the system can utilize around 93 MWh of power generated during off-peak periods and generate 76.4 MWh of additional power and 585 tons of hot water during peak hours. The optimized round trip efficiency is 44.7% and the total cost rate is $476/hr.

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.
