Lighting a Reliable Path to 100% Clean Electricity: Evolving Resource Adequacy Practices for a Decarbonizing Grid
It is the year 2045 in the carbon-neutral southwestern United States. While summer heatwaves have increased in frequency and intensity because of climate change, the region’s abundant solar generation produces tremendous amounts of low-cost energy on hot summer days. This energy not only serves daytime loads but it also charges an enormous fleet of batteries that, aided by wind and geothermal power, discharge overnight to effectively eliminate summertime electric reliability concerns.

Utility-Scale Shared Energy Storage: Business Models for Utility-Scale Shared Energy Storage Systems and Customer Participation
Due to climate change, supply scarcity, and society’s desire to expand access to electricity and improve energy-system resilience, there has been an increasing demand to invest in and use renewable energy sources (RESs) that are environmentally friendly, efficient, sustainable, and affordable. This has diversified and decentralized energy sources and increased their penetration.

Two-Scale Stochastic Control for Integrated Multipoint Communication Systems With Renewables
Increasing threats of global warming and climate changes call for an energy-efficient and sustainable design of future wireless communication systems. To this end, a novel two-scale stochastic control framework is put forth for smart-grid powered coordinated multi-point (CoMP) systems. Taking into account renewable energy sources, dynamic pricing, two-way energy trading facilities, and imperfect energy storage devices, the energy management task is formulated as an infinite-horizon optimization problem minimizing the time-averaged energy transaction cost, subject to the users’ quality of service requirements.

Obstacles to the Success of Fuel-Cell Electric Vehicles: Are They Truly Impossible to Overcome?
Cities with substantial population growth continue to encounter economic, social, and environmental challenges in their daily operations. This growth has led to public outcry demanding that societies curb their dependence on fossil fuel consumption to limit global warming. In fact, major cities’ usage of fossil fuels constitutes 75% of global energy resource use and accounts for 70% of global greenhouse gas emissions, despite occupying only approximately 5% of the planet’s total land mass. Rapid urbanization also contributes to multiple types of serious environmental pollutants (e.g., air, soil, and water), which affect the people’s health and the quality of life.
