The paper argues that while PHEVs can reduce system-wide GHG emissions by shifting energy demand from transportation to the electric sector, California's current regulations penalize utilities for the resulting load growth and increased sector-specific emissions. It suggests three primary strategies to overcome these barriers: replacing decoupling (though not recommended by the authors), implementing independent metering to create a separate PHEV rate class, and allocating a portion of transportation-sector GHG reductions to the utility sector.

The report identifies nine key drivers—including energy cost savings, stakeholder demand, and smart building technology—that enable corporations to move beyond incremental sustainability gains toward higher energy performance and net-zero buildings.

This fact sheet outlines RMI's history of developing market-based solutions for energy efficiency and climate protection. Key achievements include the creation of the Hypercar concept to reduce oil dependence, the development of the Natural Capitalism framework for sustainable business, and the establishment of the LEED green building rating system. The organization has also worked extensively on military energy security, water efficiency, and the promotion of decentralized low-carbon power generation over nuclear energy.

The authors contend that energy efficiency is a far more cost-effective and reliable method for reducing oil dependence than drilling in frontier areas or investing in synthetic fuels. They provide data showing that from 1973 to 1986, efficiency gains significantly outperformed supply expansions in terms of effective energy supply. The paper highlights the transportation sector, particularly light-vehicle efficiency, as the most critical area for potential savings, suggesting that higher CAFE standards could save billions of barrels of oil. It also examines savings in buildings, industry, and utilities, arguing that these 'negabarrels' are cheaper to produce than extracting new oil. Finally, the authors link energy efficiency to broader national security goals, including the mitigation of climate change, the reduction of nuclear proliferation, and the decrease of geopolitical volatility in the Middle East.

The report critiques the U.S. reliance on military force and nuclear deterrence, arguing that such policies create instability and economic decay. It proposes a 'Security Without War' model centered on nonprovocative defense (NPD), where military forces are structured exclusively for defense to avoid provoking adversaries. The authors advocate for addressing the root causes of conflict through sustainable resource management, debt relief for the Third World, and the promotion of 'strong democracy'—characterized by minority protections and civil society—both domestically and abroad. The document also calls for the total international control and eventual disarmament of nuclear weapons, the strengthening of the United Nations and World Court, and the empowerment of municipal governments to conduct non-military foreign policies.

The paper investigates whether advanced composite bodies-in-white (BIW) can be affordable for mass production, using the GM Ultralite as a case study. It employs Technical Cost Modeling to compare a composite monocoque with a steel unibody across manufacturing, operation, and post-use phases. The analysis finds that while material costs for carbon fiber are high, they can be offset by significantly lower tooling and equipment costs, especially when using 'soft' composite tooling and rapid-curing technologies. The study concludes that composite BIWs can be cost-competitive with steel at carbon-fiber prices around $11/kg ($5/lb) with modest mass reductions, and are already more competitive in total lifecycle costs at production volumes below 75,000 units per year.

The document outlines four plausible scenarios for the year 2010 based on federal regulatory roles and financial environments. It advocates for a 'water soft path' paradigm shift, moving from centralized, demand-driven 'gray infrastructure' toward decentralized, efficient, and integrated 'green infrastructure.' The author identifies drivers for this transition, including end-use efficiency, waterless sanitation, stormwater harvesting, and technological spill-overs from the distributed energy revolution, such as fuel cells and hybrid-electric vehicles.

The executive summary of 'Winning the Oil Endgame' argues that displacing all oil used in the United States would be more profitable than continuing to purchase it. The proposed roadmap involves doubling oil efficiency—primarily through ultralight vehicle design—developing a domestic biofuels industry, and utilizing natural gas and hydrogen as substitutes. The authors suggest that an investment of $180 billion over a decade could result in an annual gross economic benefit of $130 billion by 2025. To accelerate this transition, the document recommends policies such as 'feebates' for vehicles, scrap-and-replace programs for low-income citizens, and federal loan guarantees for automotive retooling.

The SHIFT Calculator estimates induced travel—the increase in vehicle miles traveled (VMT) following road capacity expansions—using empirical elasticities. It applies a 1.0 ratio for interstate highways and 0.75 for other freeways and arterials, predicting that a 1% increase in lane mileage leads to a corresponding increase in VMT over 5 to 10 years. The tool also calculates cumulative greenhouse gas emissions through 2050 based on two scenarios: a business-as-usual case and one aligned with the US Nationally Determined Commitment (NDC), which assumes 100% electrification of new passenger vehicles by 2035.

The VPP Flipbook outlines how utilities can aggregate distributed energy resources (DERs)—such as batteries, electric vehicles, and smart thermostats—to provide grid services like capacity, energy, and resilience. It details a six-step development process and provides specific examples from utilities including PG&E, National Grid, and Green Mountain Power. The document emphasizes the importance of open-access structures, third-party partnerships, and the integration of VPPs into long-term resource planning to address load growth and decarbonization goals.
