SPATIAL AND TEMPORAL INTERACTIONS OF SOLAR AND WIND RESOURCES IN THE NEXT GENERATION UTILITY
The research demonstrates that creating optimized portfolios of geographically diverse wind and solar sites significantly reduces power output variability compared to individual sites. In the modeled U.S. Midwest region for 2004, combined wind and solar portfolios achieved an average variability reduction of 55% below the average of individual sites. The study finds that a small subset of available sites is often sufficient to achieve most of these variability reductions. To manage remaining variability, the authors propose integrating responsive loads, energy storage via electric vehicles, and intelligent grid communications.

Intermittent Renewables in the Next Generation Utility
The research demonstrates that geographically distributing wind farms reduces the variability of power output and drastically decreases the frequency of zero-production periods compared to individual sites. Using 2004 data from the U.S. Midwest and Texas, the analysis shows that optimizing portfolios based on negative covariance between sites improves capacity credit and system reliability. The authors argue that this approach, combined with demand-side resources like plug-in vehicles and real-time load response, is essential for the transition to a next-generation utility capable of integrating significantly higher levels of intermittent renewables.

Triple Safety: Lightweighting Automobiles to Improve Occupant, Highway, and Global Safety
The document examines the relationship between vehicle weight, fuel efficiency, and safety. It argues that lightweighting can significantly reduce global greenhouse gas emissions—potentially by up to 11% if combined with plug-in hybrid electric vehicles (PHEVs) and a clean grid—without compromising occupant safety. The author contends that vehicle size and design, rather than mass, are the primary drivers of crashworthiness. The paper reviews statistical literature to debunk the 'weight confers safety' argument and provides examples of aluminum, high-strength steel, and carbon fiber composites being used in safe, lightweight vehicles.

Valuation of Renewable and Distributed Resources: Implications for the Integrated Resource Planning Process
The document argues that traditional integrated resource planning (IRP) is too generation-centric and fails to account for the specific operational, financial, and grid-side benefits of distributed and renewable energy. It introduces the Energy Resource Investment Strategy (ERIS) methodology, which uses probabilistic load and fuel forecasting and portfolio theory to value these resources. Key technical discussions include the use of Effective Load Carrying Capability (ELCC) to measure reliability contributions, the role of geographical dispersion in reducing portfolio variability, and the financial advantages of modular, short-lead-time resources in mitigating the risk of overbuilding capacity.

The Energy Challenge: A New Agenda for Corporate Real Estate
The report identifies a significant gap between the perceived importance of energy efficiency and the actual implementation of management structures in corporate real estate. While executives view sustainability as a priority, fewer than half of surveyed companies have formal energy policies or quantitative targets. The document argues that most barriers are perceived and can be overcome through integrated design, senior leadership, and the adoption of comprehensive energy management systems. It highlights that 'low-hanging fruit'—such as retro-commissioning and schedule adjustments—are often overlooked in favor of more expensive system replacements. Through case studies of companies like Adobe, Toyota, and ABN AMRO, the report demonstrates that integrated solutions and real-time data tracking can lead to substantial cost savings and carbon reductions. It concludes with action plans for corporate stakeholders and service providers, urging the adoption of the 2030 Challenge targets to achieve carbon neutrality in the building sector.

Accelerating Progress Toward a Sustainable Hawai`i Island
The report evaluates Hawai`i County's goals across ten areas, including affordable housing, energy self-sufficiency, and environmental stewardship. It argues that the loss of local land control to outside investors is the island's most critical challenge, driving a housing crisis and eroding the social fabric (ohana). RMI recommends implementing land trusts, deed restrictions, and green building standards to ensure permanent affordability. The document emphasizes 'whole-system thinking' to address root causes rather than symptoms, suggesting that the county maximize its local economic multiplier by producing energy and food locally. A significant portion of the report is dedicated to proposing specific indicators to measure progress toward these goals to ensure transparency and durability.

Nuclear Power and Climate Change
The document is a series of exchange entries between Amory Lovins, Peter Bradford, and R. Stephen Berry. Lovins argues that nuclear power is a 'market loser' and that 'negawatts' (energy efficiency) and micropower are faster, cheaper, and more effective climate solutions. Bradford supports this view, highlighting the high financial risks, the need for massive taxpayer subsidies, and proliferation concerns. Conversely, Berry argues that energy efficiency alone cannot meet the growing energy demands of developing nations like China and India, and that nuclear power is a necessary, reliable, and potentially cost-competitive option if carbon costs are internalized.

Nuclear power: economics and climate-protection potential
The paper asserts that nuclear power is a 'market loser' compared to windpower, cogeneration, and energy efficiency. It claims that nuclear power's high costs and long lead times result in a high opportunity cost, where investments in nuclear power displace far more carbon-reducing capacity than they provide. The author argues that a diversified portfolio of decentralized resources is faster, cheaper, and larger in potential than nuclear power, and that government subsidies for nuclear energy retard overall climate protection efforts.

Follow-up to Oral Testimony ‘Hearing to Examine the Rise of Domestic Energy Prices’
The Rocky Mountain Institute (RMI) outlines immediate strategies to lower U.S. crude oil demand, arguing that a 5% to 9% reduction would remove 1.0 to 1.8 million barrels per day from the global market. Proposed measures include reducing speed limits for non-Class 8 vehicles to 60 MPH, increasing the federal Gross Vehicle Weight Rating (GVWR) for trucks to 110,000 lbs, and mandating Auxiliary Power Units (APUs) for new Class 8 tractors. RMI suggests these actions, combined with increased biofuel procurement and the adoption of 'total-flex' vehicle technology, would restore global excess capacity to 2.5 to 3.8 million barrels per day, thereby reducing price volatility.
