The report identifies solar hybrid mini-grids as the fastest-growing segment of the decentralized energy market, noting that they could serve approximately 111 million households in sub-Saharan Africa, Asia, and small island states by 2030. While technical costs are decreasing due to solar and battery advancements, the market faces significant hurdles including limited consumer paying capacity, ambiguous rural electrification policies, and a heavy reliance on public grants over commercial financing. The document advocates for results-based financing (RBF), flexible tariff regulations, and clear legal protections for mini-grid assets against the arrival of the main grid to attract private investment.

The document analyzes the success of Public Service Company of Colorado (PSCo) in achieving low-cost renewable energy bids through a regulated competitive procurement process. It argues that utilities, as single buyers (monopsonies), have incentives to disadvantage suppliers to maintain market control and financial advantages. To mitigate this, the author proposes specific regulatory measures—such as public planning scrutiny, independent bid evaluators, and the filing of draft requests for proposals—that were implemented by the Colorado Public Utilities Commission (COPUC). The brief concludes that utility ownership and competitive bidding can coexist if the process is transparent and linked to approved resource plans, ensuring consumers benefit from current market prices for wind and solar.

The production of industrial metals accounts for over 10% of global greenhouse gas emissions, a figure likely to rise as declining ore grades increase the energy required for extraction. Using copper as a flagship example, the report demonstrates that mining operations can achieve 45% renewable electricity while improving financial performance and resilience. RMI's modeling across 25 sites in five countries shows that a 'one-size-fits-most' approach—combining large-scale solar with other renewable technologies or utility buyback programs—can maintain internal rates of return (IRR) while increasing net present value (NPV). The report identifies market, structural, organizational, and behavioral barriers to adoption and suggests financing mechanisms like Power Purchase Agreements (PPAs) to mitigate high upfront capital costs. To reach net-zero emissions by 2050, the report advocates for further electrification, energy productivity reforms, and new metallurgical processes.

The report outlines a 'Reinventing Fire' scenario for China to decouple economic growth from energy consumption and carbon emissions by 2050. By prioritizing demand reduction, electrification, and a shift to non-fossil energy, China could maintain GDP growth while reducing primary energy demand to 2010 levels. Key strategies include structural industrial shifts, passive building design, multimodal transportation optimization, and a three-stage transition of the power sector from coal to renewables. The analysis suggests this transition is cost-effective, with a potential net present value savings of 21 trillion RMB.

The Union of Concerned Scientists argues that energy storage can provide direct public health, economic, and resilience benefits to underserved communities if policymakers intentionally design targets, incentives, and utility planning processes to prioritize equity. The brief highlights the potential for storage to replace polluting 'peaker' plants, reduce demand charges for low-income residents, and maintain critical services during disasters, while warning that these outcomes require explicit policy mandates and stakeholder engagement.

The IRP 2019 identifies an immediate risk of power shortages in South Africa due to the declining energy availability factor (EAF) of Eskom's fleet and the decommissioning of old coal plants. To mitigate this, the plan recommends a medium-term power purchase programme, the life extension of the Koeberg nuclear plant to 2044, and the continued operation of plants despite minimum emission standard non-compliance. Long-term, the plan envisions a diversified energy mix shifting from coal toward renewables, gas, and nuclear, while emphasizing a 'just transition' to protect jobs and local economies. It specifically proposes 2,500 MW of new nuclear capacity and the integration of the Grand Inga Hydropower Project from the DRC.

The briefing advocates for net-zero energy districts, highlighting how urban-scale planning enables energy balancing across diverse building types, economies of scale for thermal systems, and reduced transportation emissions. It provides examples of smart developments in the US and India that integrate solar microgrids and battery storage to provide grid services and avoid infrastructure costs.

The policy brief contends that new natural gas capacity is a primary driver of increased grid emissions in the US and that avoiding 90% of proposed gas plants could save electricity customers over $29 billion. It advocates for a transition to 'clean energy portfolios'—combinations of wind, solar, batteries, demand flexibility, and energy efficiency—to support economy-wide decarbonization and meet international climate targets.

The document provides a detailed breakdown of 'green jobs', highlighting that the U.S. energy efficiency sector employs over 3 million people and the global renewable energy sector employed 11 million in 2018. It identifies China as the global leader in renewable energy employment and notes the emergence of climate adaptation and resilience as critical new areas of job growth, despite a lack of standardized tracking codes in the U.S. Bureau of Labor Statistics system.

The document provides a comprehensive overview of 'green jobs', highlighting that the U.S. energy efficiency sector employs over 3 million people and the global renewable energy sector employed 11 million people in 2018. It details specific employment figures for various technologies—such as solar, wind, and biofuels—and identifies China as the global leader in renewable energy employment. Additionally, it notes the emergence of climate adaptation and resilience jobs, though standardized data collection for these roles remains limited.

The paper argues that current wholesale electricity markets, designed for large fuel-burning plants with high production costs, are ill-equipped for a future dominated by wind, solar, and storage, which have near-zero production costs and different operational characteristics. It identifies a disconnect between federal wholesale rates and state retail rates as a barrier to demand-side flexibility. The authors propose ten principles for modern markets—including technology neutrality, grid reliability, and long-run efficiency—and outline two emerging pathways for reform: a "Robust Spot Market" approach focusing on decentralized bilateral contracting, and a "Long-Term Plus Short-Term Markets" approach utilizing a centralized forward market.

The document examines the risks that current short-term wholesale electricity markets, based on locational marginal prices (LMPs), may fail to provide sufficient price signals to sustain the investment needed for deep decarbonization. This is primarily due to the minimal short-run marginal costs of variable renewable energy (VRE) and the fact that VRE resources often cannot capture scarcity prices during production lulls. To mitigate this, the authors propose long-term markets that provide contractual certainty through power purchase agreements (PPAs) or similar mechanisms. The report compares three specific proposals (by Corneli, Gimon, and Pierpont), identifying six core commonalities: the use of long-term contracts, voluntary participation, coordination with short-term markets, incremental implementation, optimized policy guidance, and organic implementation pathways. The authors suggest that these long-term markets can better identify efficient portfolios of VRE, storage, and flexible load across broad regions, reducing the risk of overbuild or incompatible resource mixes.

The report explores how large utility customers, including cities and corporations, can achieve high renewable energy goals through various procurement models. It details options such as green tariffs, sleeved PPAs, and community solar, while addressing the critical role of Renewable Energy Certificates (RECs) in accounting and disclosure. The document emphasizes the need for collaboration between utilities, customers, and regulators to ensure that the transition to carbon-free energy is cost-effective, avoids cross-subsidization of non-participants, and maintains grid reliability.

The Green Economy Coalition responds to the UK Committee on Climate Change's (CCC) recommendation for the UK to reach net-zero emissions by 2050. While welcoming the target as a roadmap for other economies, the Coalition argues that net-zero by 2050 is a minimum starting point and may be too cautious regarding technology and societal change. The document emphasizes that decarbonization alone is insufficient, calling for a transition to a green economy that addresses biodiversity loss, ensures a just transition through deliberative democracy, and implements Green New Deal policies to prevent corporate monopolies over new green infrastructure.

The Union of Concerned Scientists and a coalition of stakeholders established six policy principles for energy storage to ensure the transition to clean energy benefits disadvantaged and frontline communities. These principles focus on reducing emissions, improving disaster resilience, promoting local economic development through job training, accelerating renewable energy deployment, protecting consumers from high costs, and ensuring transparent community participation in project planning.

RMI research indicates that clean energy portfolios are now cost-competitive with new natural gas power plants. Consequently, over $70 billion in planned gas-fired power plant construction and $30 billion in new interstate pipelines face significant stranded cost risks, as these assets may become uneconomic by 2035 and lead to increased gas delivery costs.

The document provides an overview of energy storage solutions, highlighting the transition from traditional pumped-storage hydropower to advanced battery technologies like lithium-ion. It details the technical trade-offs between different storage methods, the economic trends driving adoption, and the regulatory environment in the U.S. aimed at increasing grid flexibility and resilience.

India can integrate 390GW of wind and solar generation by 2030 at a lower total system cost than its current trajectory by increasing the flexibility of electricity supply and demand. The report identifies four primary flexibility needs: operating reserves, ramping, daily balancing, and seasonal balancing, all of which will grow as renewable energy penetration increases. A 'balanced portfolio' combining demand-side management, energy storage, and powerplant flexibility is found to be the most cost-effective approach, reducing energy waste by 82% to 97%, total system costs by 5% to 8%, and carbon emissions by 8% to 12% compared to a thermal-only approach. Regional analysis reveals that states like Tamil Nadu and Karnataka will face acute seasonal and ramping challenges, while Uttar Pradesh could act as a flexibility exporter due to its industrial base. The report concludes that urgent action on data, market design, and infrastructure is required to unlock these flexibility resources.

The document examines various energy storage solutions, including pumped-storage hydropower, batteries, and compressed air, highlighting their capacity to mitigate the intermittency of solar and wind power. It details the dominance of pumped-storage hydropower in the U.S. utility-scale market and the rapid growth of lithium-ion batteries. The text also outlines specific state-level storage targets in the U.S. and global projections for storage capacity needed to limit global warming to 2 degrees Celsius.

The report finds that while there is a general availability of skilled labour in Atlantis, many qualified residents commute to Cape Town, leaving local businesses to report skills shortages. It argues that the future of the A-SEZ lies in medium-sized, value-adding green businesses rather than mega-factories, as the utility-scale renewable energy market has been hindered by poor government implementation of the REIPPPP. The audit identifies a critical gap in 'soft skills' and STEM competencies, alongside systemic failures in the local education sector, particularly at West Coast College, which serves non-local students more than residents. Recommendations include a 'whole of society' approach to education, the establishment of a community ICT centre, and targeted bursaries for high-tech tooling training.
