Making Customer Battery Storage Work for a Cleaner, Less Expensive Grid
This briefing by RMI argues that current commercial electricity rate designs, specifically noncoincident demand charges, encourage inefficient battery storage use that can conflict with the needs of renewable-heavy power grids. The document advocates for a transition to time-varying rates and compensation for grid services to better align customer incentives with system-wide operational requirements.

Why We Still Need To Discuss Grid Defection
This statement by the Rocky Mountain Institute (RMI) defends its 2014 research on 'grid defection'—the economic viability of customers disconnecting from utilities in favor of on-site solar and battery systems—against interpretations of a subsequent study by the Rochester Institute of Technology (RIT). RMI argues that while full grid defection may currently only be economical in Hawaii, the downward trajectory of distributed energy resource (DER) costs creates a systemic risk of stranded utility assets and empowers customers to influence the pace of decarbonization and grid investment.

Greening the Pot Industry
This RMI briefing discusses the significant electricity demand generated by the legal marijuana industry in the United States and proposes strategies for utilities and regulators to manage this load. It suggests that energy efficiency investments, on-site renewables, and time-varying rates to shift consumption to periods of low net load can help integrate renewable energy and reduce operating costs for growers.

Pathways to 1.5°C
RMI's briefing outlines a market-driven pathway to limit global temperature increases to 1.5°C by the end of the century. The analysis suggests that a nearly 100 percent renewable energy system is feasible by the mid-2050s if the adoption of clean energy follows the disruptive S-curve patterns seen in previous industrial revolutions, such as the rise of the automobile.

Annual U.S. & Global Geothermal Power Production Report
The 2016 Annual U.S. & Global Geothermal Power Production Report details a global operating capacity of 13.3 GW across 24 countries, with a forecast to reach 18.4 GW by 2021. While the U.S. maintains a significant presence with 3.7 GW of nameplate capacity, the report highlights vast untapped global potential (only 6-7% utilized) and growth in regions like East Africa and Central/South America. It emphasizes the role of geothermal energy in meeting COP21 climate commitments and outlines the GEA's project tracking methodology.

Offshore Wind: Can the United States Catch up with Europe?
As of 2016, Europe dominated the global offshore wind market, with the UK, Germany, and Denmark leading in installed capacity. The United States, while possessing vast potential (over 4,000 GW), was in the early stages of deployment with its first commercial project at Block Island. The document highlights the technical advantages of offshore wind—such as stronger winds and proximity to coastal population centers—and notes the significant job creation potential in the EU sector.

THE ECONOMICS OF DEMAND FLEXIBILITY
This executive summary from the Rocky Mountain Institute (RMI) analyzes the economic potential of "demand flexibility" (DF)—the use of technology to shift electricity consumption to lower-cost times. The report argues that DF can significantly reduce both customer electric bills and overall grid investment costs by treating demand as a flexible resource ("flexiwatts") rather than a static load.

RATE DESIGN FOR THE DISTRIBUTION EDGE
This RMI research paper argues that traditional bundled, volumetric electricity rates are inadequate for a grid with increasing distributed energy resources (DERs). It proposes a transition toward more sophisticated pricing across three dimensions: attribute unbundling, temporal granularity (e.g., real-time pricing), and locational granularity (e.g., 'hot spot' credits). The authors recommend a staged implementation using default and opt-in rates, supported by third-party technologies to maintain a simple customer experience, and call for greater data transparency and improved valuation methodologies for regulators.

Should the Renewable Fuel Standard Be Reformed?
The Environmental and Energy Study Institute argues against reforming or repealing the Renewable Fuel Standard (RFS), asserting that the policy has successfully reduced petroleum dependence and stimulated the rural economy. While acknowledging challenges such as land use change and the 'blend wall,' the author contends that these issues should be addressed through the Farm Bill and EPA flexibility rather than statutory changes, which could jeopardize billions in private investment in next-generation biofuels.
