Renewable Energy’s Footprint “Myth”
Many nuclear advocates argue that renewable electricity has far too big a land ‘footprint’ to be environmentally acceptable, while nuclear power is preferable because it uses orders of magnitude less land. If we assume that land-use is an important metric, a closer look reveals the opposite is true.
Factor Ten Engineering Design Principles
Designers often assume that radical efficiency is too expensive. Yet RMI’s Factor Ten Engineering initiative demonstrates that very large energy and resource savings can be very profitable across a wide range of applications. Factor Ten Engineering uses such innovations to transform design and engineering practice, via whole-system thinking and integrative…
Integrative Design: A Disruptive Source of Expanding Returns to Investments in Energy Efficiency
This paper summarizes the principle of integrative design. Integrative design rigorously applies orthodox engineering principles, but achieves radically more energy- and resource-efficient results by asking different questions that change the design logic. Examples described in this paper for buildings, industry, and vehicles show that optimizing whole systems for multiple benefits,…
Presentation of Achieving Low-Cost Solar PV: Industry Workshop Recommendations for Near-Term Balance-of-System Cost Reductions
This presentation provides a high-level overview of key technical and process best practices that emerged from RMI’s June 2010 “Solar PV Balance of System” design charrette in a graphical format. It includes the main charts and graphs that summarize the report analysis and recommendations. BoS costs—all the upfront costs associated…
Efficiency and Micropower for Reliable and Resilient Electricity Service: An Intriguing Case-Study from Cuba
Cuba’s decrepit electricity grid suffered 188 days of significant blackouts in 2004, 224 in 2005, 3 in 2006, and 0 in 2007. This dramatic improvement was due to a nationwide efficiency program, a crash program of switching to a majority of distributed generation, and reorganizing grid architecture around islandable netted…
