Summary: As energy supplies shift towards renewable energy, conventional power plants need to improve flexibility to balance the volatility. The integration of energy storage devices proves helpful in increasing ramp-rates and reducing minimum-load. A valuation tool based on market data showed that pumped hydro storage systems and power-to-gas systems can improve profitability, while other storage types require additional market opportunities. Battery storage systems can reduce ramp time but are not suitable for day-ahead and intra-day markets.

Summary: The city of Espoo plans to abandon coal in its district heating system by 2025, replacing it with renewable fuels, heat pumps, and waste heat utilization. This transition will significantly reduce CO2 emissions with a small increase in production costs. Utilizing waste heat can further reduce emissions and prevent an increase in production costs.

Summary: This paper models the production process using a novel by-production approach and ensures the linkage between economic and environmental sub-technologies. It adjusts the byproduction Data Envelopment Analysis model to obtain positive shadow prices and derives the shadow prices of carbon dioxide emissions for province-level industrial sector data in China from 1997 to 2019. The findings show that the shadow price of carbon has increased over time, indicating the effectiveness of policymakers' efforts in reducing carbon emissions in manufacturing. The significant variation in shadow prices across provinces can be explained by factors such as carbon productivity, non-fossil energy consumption, and urbanization rate.

Summary: Since 2011, the UK has been bound by EU energy reduction targets, reducing energy use by 18% by 2019. Post-Brexit, the UK can now choose its own 2030 energy target, with a 40% reduction offering the largest economic and employment benefits. Careful policy considerations are needed to ensure overall energy efficiency improvements.

Summary: Fruits and vegetables are more susceptible to high postharvest loss and one key strategy to overcome such losses is through cold chain integration. However, most developing countries lack the basic infrastructure and management skills needed for integrated cold chains, particularly in rural areas. This review addresses the need to adopt and strengthen measures for precooling and cold storage of fruits and vegetables to improve their value chains, especially for small-scale farmers in rural communities.
