Analysis of Grey and Natural Infrastructure for Lake Conservation Applying the Sustainable Asset Valuation (SAVi) to Lake Dal, in Srinagar, State of Jammu & Kashmir, India
The document assesses five scenarios for the conservation of Lake Dal, ranging from business-as-usual to hybrid infrastructure upgrades. Using the SAVi tool, it finds that a hybrid approach—combining upgraded sewage treatment with a 500 ha artificial wetland—yields the highest net benefits (INR 360 billion) and the best water quality improvements. Conversely, the 'business-as-usual' scenario predicts a continuous decline in water quality and severe revenue losses for tourism and fisheries by 2060. The analysis also indicates that constructing the Western Foreshore Road would reduce tourism and fishery revenues by over INR 72 billion compared to the hybrid scenario due to damage to lake integrity.

Green Cape 2040: Towards a smarter grid
The document warns that increasing residential solar PV adoption in the Western Cape will likely lead to significant municipal revenue losses, as high-income consumers reduce their reliance on the grid. Using the International Futures (IFs) model, the authors project that under a 'Current Path' scenario, the province could lose nearly 11% of municipal revenue cumulatively by 2040. To counter this, the brief proposes a sequential policy approach: short-term investment in Advanced Metering Infrastructure (AMI) to gather data, medium-term implementation of feed-in tariffs (FIT) and Time of Use (ToU) tariffs to reclaim revenue, and long-term strategic investment in a 'smart grid' and the local PV manufacturing industry. The 'Embrace and Enhance' scenario, which combines high levels of smart infrastructure investment with local manufacturing and ICT spillovers, is forecast to result in the lowest cumulative revenue losses, although it still does not fully offset the impact of decentralized energy production.

The Origins of the Nuclear Power Fiasco
The author describes the U.S. nuclear power industry as the "greatest collapse of any enterprise in industrial history," attributing this failure to a combination of institutional hubris, skewed economic data, and a federal policy focus on hardware over energy efficiency. The text details how the Atomic Energy Commission (AEC) and the Department of Energy (DOE) promoted myths regarding the cost-competitiveness of nuclear power compared to coal and ignored the potential of energy productivity improvements. It further examines the failure of the breeder reactor and reprocessing programs, arguing that the federal government continues to subsidize an uncompetitive technology while ignoring cheaper, more efficient alternatives.

Sustainable Zero Net Energy – Identifying the Essentials for Solutions
The document examines the transition toward zero net energy (ZNE) buildings and distributed energy resources (DERs), highlighting the misalignment between traditional utility business models and the bidirectional power flows of ZNE designs. It argues that current volumetric rate structures and net energy metering (NEM) can create economic inefficiencies and equity issues. To resolve this, the authors propose a framework involving more rigorous measurement of DER impacts, the use of price signals to align customer incentives with grid value, and the evolution of utility models toward either incentive-based regulation or a 'network utility' approach. The paper emphasizes the need for metrics that account for short-term grid interaction rather than just annual energy balances.

Climate Making Sense and Making Money
The report posits that climate change is an artifact of resource inefficiency and that mitigating it can be done at a profit. It highlights that energy efficiency, switching to low-carbon fuels, and improving forestry and farming practices can reduce greenhouse gas emissions while lowering costs for businesses and governments. The text argues against the necessity of nuclear power, citing its high cost and market failure, and instead promotes wind, solar, and combined-cycle gas turbines. It suggests that market-oriented policies, such as those established by the Kyoto Protocol and the Montreal Treaty, can incentivize carbon reductions through trading mechanisms. The document concludes that the transition to a low-carbon economy can be managed without net job losses, provided there is transitional support for displaced workers in the fossil fuel sector.

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.

Amory and Judy Lovins’ Response to Jeffrey Ball’s article in The Wall Street Journal, “The Homely Costs of Energy Conservation”
The document is a response by Amory and Judy Lovins to a Wall Street Journal article regarding their home's energy efficiency. The authors argue that their original 1982–84 house achieved 90% electricity savings and 99% heating energy savings with a minimal cost premium of $6,000, which was recovered in ten months. They distinguish this from a later 2007–09 renovation that was more costly because it focused on 'bleeding-edge' technology and aesthetics rather than basic efficiency. The authors promote 'integrative design'—where high insulation levels eliminate the need for expensive heating systems—as a method to reduce energy use by over 80% at comparable or lower capital costs. They cite examples such as 'passive houses' in Europe and specific projects in Bangkok and California to demonstrate that these economics apply across different climates and scales.

The Nuclear Illusion
The paper contends that nuclear power is experiencing a global collapse due to excessive capital costs and financial risks, making it unfinanceable in private markets. It asserts that 'negawatts' (energy efficiency) and 'micropower' (distributed renewables and cogeneration) are cheaper, faster to deploy, and more reliable alternatives. The authors argue that investing in nuclear power actually worsens climate change by diverting funds from more cost-effective carbon-reduction options. The document further claims that nuclear power fails to enhance energy security due to dependencies on foreign uranium and fuel-cycle technology, and increases proliferation risks.

Best Practices for Electrifying Rural Health Care Facilities with Decentralised Renewables
The report argues that decentralised renewable energy (DRE) is the most effective solution for electrifying rural health facilities, particularly during health crises like COVID-19. It proposes a delivery model combining 'smart grants' for upfront capital expenditures (CAPEX) with market-based compensation mechanisms, such as long-term Power Purchase Agreements (PPAs), to ensure both rapid deployment and long-term financial and technical sustainability. Through 16 case studies across Africa, Asia, and Latin America, the document demonstrates how DRE can improve maternal and child health outcomes, enable the storage of vaccines, and foster socio-economic development by integrating health facilities as central nodes for wider community electrification.
