NET ENERGY METERING, ZERO NET ENERGY AND THE DISTRIBUTED ENERGY RESOURCE FUTURE
The report examines how the growth of distributed energy resources (DERs), particularly rooftop solar PV, disrupts traditional utility business models in California. It argues that existing volumetric rate structures and net energy metering (NEM) create economic misalignments and cost shifts from solar adopters to non-adopters. To resolve this, the authors propose three building blocks: improving the measurement of DER costs and benefits, implementing pricing models that reflect the actual value of energy based on time and location, and adapting utility business models toward either an 'incentive regulation' or 'network utility' approach.

Efficiency and Micropower for Reliable and Resilient Electricity Service: An Intriguing Case-Study from Cuba
Between 2004 and 2007, Cuba transitioned from a fragile, centralized power system plagued by frequent blackouts to a more resilient model. This was achieved through 'La Revolución Energética', which combined the mass replacement of inefficient appliances (lamps, refrigerators, air conditioners) with the installation of 1,854 diesel and fuel-oil-fired microgenerators. This decentralized architecture improved resilience against hurricanes and reduced oil consumption per kWh compared to central plants, while the country began shifting toward long-term renewable goals including wind, solar, and bagasse cogeneration.

Regional Energy Security Dynamics in Southern Africa
The report examines energy security in Southern Africa, focusing on the need to expand electricity generation capacity and diversify away from coal. It identifies the Southern African Power Pool (SAPP) as a key mechanism for regional cooperation to exploit vast hydropower potential in countries like the Democratic Republic of the Congo and Mozambique. However, the report notes that urgent short-term power shortages often lead countries, especially South Africa, to rely on quicker, coal-fired solutions, creating a 'lock-in' effect. It argues that for SAPP to succeed, the region must overcome significant regulatory risks, high upfront capital costs for hydropower, and a lack of cost-reflective pricing in national utilities.

Keeping the Lights On While Transforming Electric Utilities
The report challenges the traditional utility assumption that 'baseload' power plants are necessary for grid stability, noting that all generators, including coal and nuclear, experience outages. It proposes a new electricity paradigm integrating energy efficiency, demand response, renewables, and storage. The authors assert that variable renewables like wind and solar can reliably meet demand if utilities use existing plants differently, incorporate new storage technologies, and increase control over demand. Examples from Denmark, Germany, and a NREL study on the eastern U.S. are cited to demonstrate the feasibility of high renewable penetration.

Nuclear Nonsense
Amory B. Lovins critiques Stewart Brand's advocacy for nuclear power, asserting that nuclear energy is economically uncompetitive and slower to deploy than decentralized renewables and efficiency measures. Lovins argues that nuclear power's high capital costs and financial risks make it a poor investment for climate protection, noting that it saves significantly less carbon per dollar and is deployed much slower than alternatives. He refutes claims regarding the necessity of 'baseload' power, the land-use footprint of renewables, and the need for a diverse energy portfolio that includes nuclear power, concluding that the technology's failure to attract private equity in the U.S. demonstrates its lack of market viability.

Measuring Energy Subsidies Using the Price-Gap Approach
The document examines the 'price-gap' method of measuring energy subsidies, which calculates the difference between domestic and world reference prices. While the author acknowledges its simplicity and utility for international benchmarking, the paper argues that the method creates 'blind spots' by ignoring subsidies that do not alter market prices, such as credit subsidies, R&D funding, and risk transfers. This leads to a significant understatement of the total fiscal and environmental costs of fossil fuel supports. The author recommends a hybrid approach, combining annual price-gap tracking with comprehensive 'transfer-based' evaluations every five years for major energy nations.

Strong Federal Transmission Policy: A Key Component of a Clean Energy Future
The Union of Concerned Scientists asserts that the United States requires federal legislation to overcome barriers in the planning and siting of transmission lines, which currently hinder the deployment of renewable energy. The document advocates for 'Green Energy Superhighways' to connect remote renewable resource areas to population centers, while emphasizing that federal authority should act as a backstop when states cannot agree on facilities of national interest. It warns that without a federal cap-and-trade system, transmission expansion in the Northeastern United States could inadvertently increase carbon emissions by allowing coal-based power to flow from non-RGGI states to those with emission caps.

Local Clean Power: Renewable Electricity Opportunities in the Southeast United States
The Southeast United States has sufficient renewable energy resources to meet up to 30 percent of its electric power needs by 2025. The region can leverage biomass, solar, wind, and low-impact hydropower to reduce reliance on conventional power, though this requires overcoming regulatory barriers such as restrictive third-party power pricing and insufficient interconnection rules. The document argues that a national or state-level renewable electricity standard (RES) would drive job growth and economic investment with minimal impact on consumer electricity costs.

Nuclear Power: Climate Fix or Folly?
The report contends that nuclear power is economically unviable, citing soaring capital costs and a lack of private investment. It argues that decentralized 'micropower'—including wind, solar, and cogeneration—alongside end-use efficiency, provides a more cost-effective means of displacing CO2 emissions and enhancing energy security. The authors assert that nuclear power's slow deployment and high financial risk make it a liability for urgent climate action, suggesting that resources should instead be shifted toward distributed energy resources.

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.

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 Washington Clean Energy Initiative: Effects of I-937 on Consumers, Jobs and the Economy
The Union of Concerned Scientists analyzed the potential effects of Washington's Initiative 937 (I-937), which would require large electric utilities to source 15 percent of electricity from eligible renewable resources by 2020 and pursue cost-effective energy conservation. Under an expected case scenario, the report projects that by 2025, I-937 would result in $1.13 billion in cumulative savings on consumer electricity bills, the creation of 2,000 new jobs, and a reduction of 4.6 million metric tons of annual CO2 emissions. The analysis indicates that renewable energy and efficiency investments would be cost-competitive with conventional fossil fuel resources, providing long-term price stability and economic development, including $2.9 billion in new capital investment. Sensitivity analyses suggest that even under pessimistic conditions—such as higher wind costs or the expiration of federal tax credits—the initiative would generally still yield long-term savings and environmental benefits.

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.
