The document outlines four key insights from successful NZE home builders in the US: the economic viability of NZE homes through integrated design, the need to shift customer communication toward comfort and income rather than technical science, the potential for prefabricated construction to mitigate labor shortages, and the reduced market risk associated with offering a highly differentiated, high-efficiency product.

The report highlights the economic and environmental advantages of transitioning transportation network company (TNC) drivers to electric vehicles. It demonstrates that high-mileage drivers can achieve significant annual savings in fuel and maintenance, which eventually offset the higher initial purchase price of EVs. Using Austin, Texas, as a case study, the document details specific utility incentives and compares EV acquisition methods—purchasing, renting, and leasing—to guide TNC drivers toward electrification.

Taiwan has introduced a renewable energy credit (T-REC) system to enable private and foreign companies to procure renewable energy, breaking the long-standing monopoly of the state-owned utility, Taipower. This initiative supports Taiwan's goal to phase out nuclear power by 2025 and increase renewable capacity to 1012.5 GW by 2030. The T-REC framework offers four procurement routes, ranging from direct power purchase agreements (PPAs) to the purchase of certificates alone. While the market is currently a 'sellers market' due to high feed-in tariff (FIT) rates, the system provides a mechanism for global companies to manage supply chain sustainability.

The policy brief outlines a 'toolbox' of six consensus policies—integrated frameworks, carbon pricing, smart subsidies, supportive innovation, energy efficiency, and electricity market design—intended to accelerate the clean energy transition. It argues that these policies can leverage private capital and existing technologies to align the world with the 2°C goal by 2030, potentially reducing annual emissions by more than double the required amount, while capturing an economic opportunity estimated to exceed $1 trillion per year worldwide.

The briefing contends that the current climate finance system is too reliant on international intermediaries and insufficient for achieving Paris Agreement goals. It proposes that national green investment banks (GIBs) provide a replicable model for developing countries to coordinate both foreign and domestic financial flows, reducing dependence on multilateral aid and enhancing national agency over low-carbon transitions.

The document argues that demand flexibility—shifting electricity use to match renewable supply—can increase renewable energy revenues, reduce curtailment, and lower carbon emissions more cost-effectively than investing in new gas-fired generation.

This fact sheet by the Rocky Mountain Institute (RMI) challenges four primary myths regarding net-zero energy (NZE) leased buildings, asserting that they can be more profitable for developers and more beneficial for employees than traditional buildings. Using the Boulder Commons project as a case study, RMI demonstrates that NZE buildings can achieve higher occupancy rates, rental premiums, and increased employee productivity. The document also outlines a four-step process for transitioning existing buildings to NZE operation and promotes the NZE Leasing Best Practice Guide to scale adoption in the commercial sector.

The briefing examines how commercial electricity rate designs, specifically noncoincident demand charges, incentivize customers to flatten their load profiles using battery storage. While this reduces individual bills, it often conflicts with the needs of grids with high renewable penetration, where flexible demand is required to match variable generation. The author suggests transitioning to peak-coincident demand charges, time-of-use rates, or real-time pricing to better align customer behavior with system-wide costs and grid stability.

RMI retracts definitive conclusions about the impact of transportation network companies (TNCs) on cities, citing significant data uncertainty regarding load factors and deadheading.

Boulder Commons is a 100,000 square foot multitenant project in Boulder, Colorado, that demonstrates the feasibility of net-zero energy (NZE) commercial real estate. The project achieved NZE through a combination of high-efficiency building systems and 575 kW of solar PV, including an innovative vertical installation on the southeast façade. The developer, Morgan Creek Ventures, implemented a specific NZE lease structure that includes plug load budgets for tenants and annual recommissioning to ensure performance. Financially, the project saw a 12% hard cost premium (excluding solar) but expects higher net cash flow due to increased tenant retention and a lower capitalization rate at the point of sale.

The document argues that the energy transition provides opportunities for utilities to serve low-and moderate-income (LMI) customers through innovative models such as on-bill financing, community solar, and virtual power plants. It highlights the systemic inequities LMI customers face, including a median energy burden of 7.2% compared to 2.3% for others, and the historical siting of polluting power plants in these communities. The report details eight specific program models—ranging from utility-owned PV systems to integrated service bundles—and emphasizes the need for utilities to shift from simply informing customers to empowering them in decision-making processes. It concludes that these shifts align with a broader utility evolution from an expanded monopoly toward a transformed platform operator.

The report examines the Nigerian minigrid sector, highlighting a potential annual revenue opportunity of ₦2.8 trillion (US$8 billion). Based on audits of ten commercial projects, it identifies best practices such as optimal site selection, community engagement, and appliance financing. While the regulatory environment is generally supportive, the report identifies barriers including high hardware costs, limited affordable finance, and inconsistent customs processes, proposing a series of stakeholder-specific actions to accelerate market growth.

The briefing challenges three myths regarding the role of renewables and distributed energy resources (DERs) in Puerto Rico's grid recovery. It asserts that renewables and energy storage are now cost-competitive with fossil fuels, with energy storage costs dropping 70 percent between 2010 and 2016. The text highlights that renewable infrastructure proved more durable than transmission networks during the 2017 hurricanes, noting that 90 percent of utility-scale solar and wind capacity remained operational or ready. Furthermore, it argues that these technologies can be deployed quickly, citing examples of large-scale storage projects completed in months, and recommends a coordinated effort by the Puerto Rico government and utility to prioritize these projects for a more resilient energy future.

The Rocky Mountain Institute (RMI) criticizes the Federal Housing Administration's (FHA) decision to cease insuring mortgages on homes with property assessed clean energy (PACE) loans. RMI argues that the FHA's concerns regarding consumer protection and default risk are misguided, as data suggests energy-efficient homes have lower default rates than inefficient ones. The document asserts that PACE provides a critical financing mechanism for energy and water efficiency retrofits that traditional loans do not fulfill, and that removing it may push homeowners toward riskier high-interest credit options.

The document argues that emerging energy technologies—including solar PV, wind, battery storage, and microgrids—are now cost-competitive and more resilient than traditional fossil-fuel-based systems. It highlights that while the 2017 hurricanes caused the longest sustained outage in U.S. history, the resulting damage provides an opportunity to rebuild the grid using distributed resources that can be deployed quickly and reduce reliance on expensive imported fuels.

The document outlines four specific actions for cities to achieve carbon-free electricity: implementing LED smart streetlighting, creating electric districts by removing natural gas infrastructure, installing municipal solar photovoltaics, and leveraging renewable energy supply mechanisms like power purchase agreements.

The document outlines three primary actions for cities to reduce their carbon footprint through biological resource management: diverting organic waste from landfills to prevent methane emissions, expanding urban forestry to create carbon sinks and reduce cooling energy needs, and promoting plant-based diets to lower food-related emissions.

The document identifies that industry accounts for 7% of carbon emissions in major cities and proposes three primary actions to mitigate this: implementing clean industrial heat solutions, replacing inefficient motors with high-efficiency models, and establishing voluntary energy management and operator training programs. It emphasizes the need for cities to partner strategically with corporate residents due to limited jurisdictional control.

The transportation sector accounts for 36% of greenhouse gas emissions in large cities. To address this, the handbook outlines several strategic actions: electrifying municipal fleets, reducing internal combustion engine (ICE) vehicles through bans or restrictions, managing urban freight emissions, expanding EV charging infrastructure, creating car-free downtown zones, and enhancing public transit and mobility alternatives like bikeshare and pedestrian-friendly streets.

The Carbon-Free City Handbook: Financing emphasizes the role of cities in expanding capital access and innovative financing mechanisms for both public sector city-led projects and private sector initiatives.
