The report argues that the 19th-century utility model, designed for centralized fossil-fuel generation, is ill-suited for the 21st-century transition to low-carbon energy. It identifies critical challenges across five business segments: generation, transmission, market operation, distribution, and customer management. A central thesis is that current investor-owned utility (IOU) and independent power producer (IPP) financial structures inflate the cost of renewables by imposing risk-return requirements tailored to fossil fuels. The author proposes shifting toward 'YieldCos', municipal financing, and crowdsourced investment to match the bond-like, long-term cash flow profiles of renewable projects, which could potentially reduce the levelized cost of energy (LCOE) by approximately 20%.

The text suggests that the impending grid parity of solar-plus-battery systems presents utilities with an opportunity to adapt their business models and regulatory frameworks to create a lower-cost electricity system for customers and society.

The Rajasthan Sun Technique CSP plant in India was made viable through a combination of subsidized power purchase agreements (PPAs), long-maturity debt from international public lenders, and a first-mover strategy by a financially strong private developer. While the project achieved low investment and production costs, the broader National Solar Mission (NSM) phase one faced significant deployment delays due to the 'winner's curse' in reverse auctions, overestimation of solar resources, and financing challenges. The project demonstrated high local content (61-71%) and the benefits of linear Fresnel technology, though it lacked energy storage. Key recommendations for scaling CSP in India include improving auction design, incentivizing storage, and mobilizing local private finance to reduce reliance on foreign public debt.

The Obama administration's FY 2015 budget proposal emphasizes a "all of the above" energy strategy and the 2013 Climate Action Plan. Key financial highlights include a $1 billion Climate Fund for community adaptation, a $56 billion resilient infrastructure package, and a 26 percent increase in Department of Transportation funding to address an $86 billion maintenance backlog. The budget proposes making renewable energy tax credits permanent and eliminating $4 billion in fossil fuel subsidies. Significant funding increases are directed toward the DOE's Office of Energy Efficiency and Renewable Energy ($2.3 billion) and various sustainable transportation and building initiatives, while the EPA's overall budget is reduced by 3.8 percent.

The document examines the risks of relying on natural gas for US electricity, noting that while it burns cleaner than coal, its expected replacement of nuclear power and its role in meeting rising electricity demand would prevent necessary emission cuts. It highlights that methane leaks from production and transport further erode climate benefits, and suggests that a transition to 80% renewable energy by 2050 is a viable, more cost-effective alternative.

The report analyzes the current state of concentrated solar power (CSP), noting that while it has potential to supply up to 10% of global energy demand by 2050, it remains expensive and heavily dependent on public support. The authors find that over 98% of total CSP investment to date has required public support. The document outlines a plan to evaluate the effectiveness of public finance through case studies in India and South Africa, expert dialogues, and a final lessons-learned paper. It details various public support mechanisms, including feed-in-tariffs, competitive tenders, reverse auctioning, and concessional loans, while highlighting the specific challenges and opportunities in emerging markets.

The report analyzes Germany's energy transition, focusing on the solar PV and wind energy sectors. It evaluates the impact of the Renewable Energy Sources Act (EEG) and its feed-in tariffs (FiT), comparing the economic, technological, and environmental outcomes of both sectors. While wind energy is found to be more competitive and innovative with lower relative subsidy costs, the solar PV sector has faced a severe crisis due to intense competition from Chinese suppliers. The document argues for a systemic approach to green industrial policy, suggesting reforms to the FiT to increase flexibility and competitiveness while addressing grid stability and institutional fragmentation.

The report examines the water-energy nexus, focusing on the trade-offs associated with hydropower and bioenergy. It highlights the role of hydropower in grid stability and the water-intensive nature of bioenergy feedstock, while emphasizing the need for integrated water management and strict sustainability criteria for private sector investments, particularly in developing countries.

King Island, Tasmania, is implementing the King Island Renewable Energy Integration Project (KIREIP) to transition from diesel-heavy power to a high-renewables system. By integrating wind, solar, energy storage, and smart grid technologies, the project aims to reduce annual diesel consumption from 4.5 million liters to 1.6 million liters, targeting a 65 percent renewable energy share. Key innovations include the use of diesel-powered rotary uninterruptible power supply (D-UPS) generators to enable periods of 100-percent-renewable penetration and the installation of Australia's largest battery system at the time. Additionally, the proposed TasWind project seeks to export large-scale wind energy to mainland Australia, though it faces local opposition regarding tourism and land use.

The document examines various energy storage technologies, ranging from established systems like pumped hydro and compressed air energy storage (CAES) to emerging solutions like flow batteries and flywheels. It highlights the critical role of U.S. federal initiatives, specifically Department of Energy (DOE) grants and Federal Energy Regulatory Commission (FERC) orders, in reducing financial risks and reforming market access to encourage utility-scale implementation. The brief also details specific U.S. projects and proposed legislation, such as the STORAGE Act, aimed at incentivizing storage to support grid stability and the integration of variable renewable energy.

The document examines various energy storage technologies, from established methods like pumped hydro to emerging battery and flywheel systems, highlighting their role in integrating renewable energy and stabilizing the grid.

Additionally, it profiles several large-scale U.S. projects and discusses proposed legislation, including the STORAGE Act, aimed at incentivizing storage deployment through tax credits.

The report examines the growth of wind and solar power in the U.S. and globally, asserting that the technical challenges of variable energy sources are manageable. It highlights successful integration by utilities like Xcel Energy and countries like Denmark and Germany. The document details various tools for maintaining reliability—including geographic dispersion, improved forecasting, transmission upgrades, and energy storage—and cites studies suggesting that renewables could provide 80% of U.S. electricity by 2050.

The 'Energy 101' Model Curriculum is a one-semester interdisciplinary framework developed by the Association of Public and Land-grant Universities (APLU) in cooperation with the U.S. Department of Energy (DOE). It aims to foster 'energy literate decision making' by combining the science of energy with economic, ethical, societal, and international factors. The curriculum is structured into five units: Introduction to Energy, Energy Basics, Energy Sources, Energy Technology and Practice, and Energy Policy and Decision-Making. It utilizes the National Training & Education Resource (NTER), an open-source cloud-based platform, to provide instructional materials and interactive graphics. The framework is currently being tested at the University of Maryland, with further implementations planned at Harford Community College and Cecil Community College.

The author proposes a two-track approach for President Obama's second term: immediate regulatory action via the EPA to reduce carbon dioxide from power plants and methane from the oil and gas industry, and a long-term strategy to revamp energy technology innovation. To achieve a target of 80 percent carbon dioxide reduction by 2050, the document suggests developing a portfolio of zero-carbon technologies, including carbon capture and storage, advanced nuclear energy, and synthetic hydrocarbon fuels, supported by more effective innovation policies and increased R&D funding.

The briefing distinguishes between two types of demand-response: 'capacity' and 'balancing'. Demand-response as capacity reduces the need for new power plants by moderating peak demand events, while demand-response as balancing uses automated technology to adjust electricity use in real-time to complement variable renewable energy output.

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.

The University of California, San Diego (UCSD) operates a microgrid that manages 42 megawatts of generating capacity, including solar photovoltaics, a cogeneration plant, and a landfill-gas fuel cell. This system allows the campus to optimize energy costs and 'island' from the main grid during emergencies, such as the September 2011 blackout affecting Southern California, Arizona, and Mexico.

The document highlights the inefficiency of the United States' building stock, which consumes 42 percent of the nation's total energy, and promotes five strategic solutions—technology adoption, integrative design, policy updates, low-cost financing, and valuing non-energy benefits—to achieve deep energy retrofits and support a cleaner electricity grid.

The document argues that while the industrial sector is the largest energy consumer in the U.S. and relies heavily on fossil fuels for heat, solar thermal technology remains largely unexploited. It details three temperature ranges for industrial heat—low (below 80C), medium (80C to 250C), and high (over 250C)—and explains that low and medium ranges are already commercially viable for industries such as food, beverage, and textiles. Key barriers to adoption include high upfront costs, the variability of solar output, and the need for effective energy storage and process integration. The report notes that global capacity is dominated by China and Europe, while the U.S. lacks large-scale incentives specifically for industrial solar heating. Case studies from Arizona, New York, and Germany demonstrate the feasibility of using flat plate, parabolic trough, and vacuum tube collectors for pre-heating, cooling, and production processes.

The Clean Air Task Force argues against the 'zero-sum' race metaphor between the US and China regarding clean energy, suggesting instead that China's capacity for large-scale demonstration and investment provides a 'test bed' that can benefit the US through 'reverse innovation' and capital flow. While acknowledging trade disputes and IP theft, the author suggests the US focus on high-end design and systems integration rather than low-end commodity manufacturing, which is increasingly automated or cost-prohibitive to ship.
