Assessing the Electric Productivity Gap and the U.S. Efficiency Opportunity
The report identifies a significant disparity in electric productivity (GDP per kWh) across U.S. states. After normalizing for climate and economic composition, RMI finds a remaining gap of 1.2 million GWh annually. Closing this gap could reduce projected 2020 electricity demand by 34% compared to business-as-usual scenarios while maintaining economic growth.

The Greening of Human Settlements
The author posits that a new industrial revolution is emerging, driven by the need to use nature more productively. By applying 'natural capitalism'—which values nature and people—and integrative design, developers can create high-performance, low-impact human settlements that are more profitable and desirable than traditional developments. Examples such as Village Homes in California and the city of Curitiba, Brazil, demonstrate that reducing resource depletion and pollution can lead to superior financial and social outcomes, including lower crime and higher market value.

Paying for Growth, Prospering from Development
The report distinguishes between 'growth' (increase in size) and 'development' (increase in quality), arguing that rapid community expansion often leads to higher taxes and degraded public services. It identifies a 'growth subsidy' where existing taxpayers fund infrastructure for newcomers, creating a cycle of dependency on further expansion. The authors propose sustainable development alternatives, such as import replacement and energy efficiency, to build local wealth without increasing community size.

Harnessing Corporate Power to Heal the Planet
The report proposes 'natural capitalism' as a new economic model where businesses profit by radically increasing resource productivity, eliminating waste, shifting from selling products to providing services, and investing in the restoration of natural capital. It argues that the current industrial model is logically flawed because it liquidates the ecosystem services upon which all life depends. By applying whole-systems thinking, the authors claim companies can achieve significant cost savings and competitive advantages, citing examples from firms like Southwire, Dow, and Interface. The text suggests that while governments can support this transition through tax policy, corporations possess the necessary agility and resources to lead the effort to heal the planet.

Natural Capitalism—Chapter 2: Reinventing the Wheels
The text proposes the 'Hypercar' as a solution to the inefficiencies and environmental damage of the traditional steel-based automobile industry. By combining ultralight composite materials, low-drag design, and hybrid-electric propulsion (specifically hydrogen fuel cells), Hypercars could drastically reduce fuel consumption and emissions. However, the author emphasizes that technological efficiency alone cannot solve traffic congestion or urban sprawl, necessitating a shift toward 'New Urbanist' design, market-based parking costs, and improved community planning to reduce the necessity of car travel.

THE ECONOMICS OF GRID DEFECTION
The report examines the economic viability of 'grid defection'—where customers use solar PV and battery storage to operate independently of the electric grid. It analyzes five U.S. geographies to determine when the levelized cost of electricity (LCOE) for these systems undercuts retail utility prices. The findings suggest that grid parity is already present in Hawaii and is imminent for millions of other U.S. customers, threatening to strand utility assets and trigger a 'utility death spiral' of rising prices and falling sales.

Truck Efficiency and GHG Reduction Opportunities in the Canadian Truck Fleet
The report argues that retrofittable efficiency technologies can offset fuel economy losses caused by 2002 and 2007 emissions regulations. It proposes two implementation scenarios for Canada's 294,000 Class-8 trucks: a 'full package' of all efficiency devices and a 'simple package' adopted by 50% of the fleet. The report emphasizes that government leadership, technical guidance, and financial incentives are essential to overcome industry obstacles and accelerate the adoption of these technologies.

IF CUSTOMERS SAVE ElECTRICITY, MUST RATES RISE?
The briefing examines the relationship between electricity efficiency and utility rates, arguing that 'fixed' costs are not static but decline through depreciation. It posits that as long as the rate of electricity saving does not exceed the combined rate of depreciation and demand growth, both rates and bills can decrease. The author contends that focusing on rates rather than total bills is economically inefficient, as efficiency measures reduce the need for costly new plant construction and allow utilities to retire expensive marginal plants first.

New Frontiers in Utility Valuation of Renewable Resources
The report argues that utilities often undervalue renewable resources by failing to account for their contribution to overall system reliability and the benefits of geographic diversification. It proposes using financial portfolio theory to minimize variability through dispersed siting and suggests that the costs of integrating intermittent renewables are relatively low compared to the risks of fossil fuel price volatility. The authors conclude that failure to apply these valuation techniques leads to unnecessary investment in conventional generation capacity.

Natural Capitalism on the U.S.-Mexican Border
The report proposes 'Natural Capitalism' as an alternative to the traditional border economy based on cheap labor and lax environmental controls. It outlines four shifts for businesses: increasing resource productivity, adopting biologically inspired closed-loop production, moving to a solutions-based service model, and reinvesting in natural capital. The document emphasizes that global supply chain pressures and consumer perceptions are forcing suppliers, including maquiladoras, to improve environmental performance to remain competitive. It further extends these principles to community development, distinguishing between 'expansion' (physical growth) and 'development' (betterment), and suggests strategies like import substitution, vendor matching, and waste-matching to increase local wealth without increasing environmental throughput.

Plug-In Hybrid Electric Vehicles and Environmentally Beneficial Load Building: Implications on California’s Revenue Adjustment Mechanism
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.

Drill Rigs and Battleships Are the Answer! (But What Was the Question?) Oil Efficiency, Economic Rationality, and Security
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.

Costing the Ultralite in Volume Production: Can Advanced Composite Bodies-in-White Be Affordable?
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.
