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.

VIRTUAL POWER PLANT FLIPBOOK
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.

Upwith the Sun: Solar Energy and Agriculture
The document describes how solar energy can be integrated into farming through solar lighting, heating, photovoltaic (PV) electricity, crop drying, and solar greenhouses. It highlights that solar energy is a practical alternative to fossil fuels and grid electricity, particularly for remote operations, and provides specific examples of cost savings and reliability improvements in livestock and crop production.

corporate-climate-appendix-e-114ce2fff63980f2.pdf
The document contains interview transcripts with executives from Denbury Resources, Exxon Mobil, NRG Energy, TECO Energy, and Waste Management (ConocoPhillips participated but declined to be quoted). The interviews explore corporate stances on climate science, the physical risks of climate change to business operations, mitigation efforts, and the funding of political or policy-oriented organizations. Findings reveal a spectrum of responses: some companies acknowledge the risks and invest in clean energy or efficiency, while others avoid taking official positions on climate science or deny that physical climate impacts currently affect their operations.

biofuels: an important part of a low-carbon diet
The Union of Concerned Scientists advocates for a 'count carbs and make carbs count' approach to transportation fuels, emphasizing the need for life cycle emissions analysis to distinguish between high-carbon fuels like liquid coal and low-carbon alternatives like cellulosic ethanol. The report highlights that while some biofuels can significantly reduce emissions, others may increase them depending on feedstock and land use. It promotes the adoption of Low Carbon Fuel Standards, citing California's model, to drive the market toward sustainable, low-carbon fuels and avoid the high emissions associated with liquid coal and tar sands.

State Progress Toward Clean Power Plan Benchmarks in 2020
The report provides a state-by-state breakdown of progress toward 2020 Clean Power Plan benchmarks, noting that some states have exceeded 500% of their goals while others show 0% progress. It highlights the role of energy efficiency, renewable energy standards, and regional initiatives in achieving these targets.

Microsoft Word - southwest.doc
The Southwest is projected to warm by 4-6°F under lower-emissions and 7-10°F under higher-emissions scenarios by the end of the century. The region faces severe water scarcity, expanding deserts, and reduced runoff, particularly in the Colorado River system. Public health risks include increased heat-related deaths in Los Angeles and worsening air quality. Economic threats include reduced yields for California specialty crops, diminished ski resort profitability due to snowpack loss, and reduced aircraft freight capacity at high-altitude airports like Phoenix and Denver. Biodiversity is critically threatened, especially in the Madrean Pine-Oak Woodlands, while mountain ecosystems face range reductions and reproductive failures in wildflowers due to earlier snowmelt and spring frosts.

Bottom Line on Emerging Solar Metering Policies
The document outlines four types of solar metering arrangements designed to overcome the limitations of the traditional "one customer, one meter" model. Net metering provides benefits to a single customer via one meter. Virtual net metering (VNM) allows multiple customers with separate meters to share credits from a system, often in multi-tenant or municipal buildings, and is permitted in states including California, Colorado, and Massachusetts. Community solar enables joint ownership or sponsorship of systems for those unable to host arrays on-site, utilizing models such as utility-sponsored, special purpose entity, or non-profit "buy a brick" projects. Meter aggregation allows a single customer with multiple utility accounts to aggregate annual consumption across separate buildings, enabling the installation of larger systems and higher power sales back to the grid.

Monarch milkweed finder
The guide identifies milkweed as the essential food source for monarch caterpillars and the only plant where they lay eggs. It attributes the decline of migratory monarch populations to the loss of millions of acres of milkweed caused by agricultural expansion, urban growth, and the use of herbicides and GMO crops. To mitigate this, the document provides a regional directory of native milkweed species for the US and Canada, categorized by soil and climate requirements, and encourages planting a variety of nectar-producing plants to support adult butterflies during their migration between Mexico and northern North America.

No Food Left Behind
The report analyzes food loss in the US specialty crop sector, contrasting the high loss rates of the fresh market with the relatively lower rates of the vertically integrated processing market. It highlights how contract-based purchasing and mechanical harvesting in the processing sector reduce in-field waste, while the fresh market suffers from strict cosmetic standards and labor shortages. The document proposes using real-time measurement and alternative harvesting models, such as the Whole Crops Harvest pilot, to rescue surplus produce for secondary markets and donations.
