Electricity generated from renewables has grown rapidly in the past few decades. However, the continued growth of solar and wind is imperiled by the high costs of grid integration. While solar and wind energy enjoy low operating costs, they are intermittent and variable on multiple time scales. Thus they may not be available when needed. Storing electrical energy is costly and so is providing backup power. Thus grid integration costs rise with the growth of solar and wind generation. There is a strong positive correlation between installed wind and solar capacity versus the residential energy price in 21 member countries… [more]

Industry production systems underlying the Food, Energy, and Water (FEW) Nexus have traditionally treated pollution and waste as externalities that often end up in a landfill. Food waste is the single largest component of municipal solid waste reaching landfills today and is often the byproduct of many FEW Nexus inefficiencies. Inefficiencies that can be addressed through technologies such as anaerobic digesters. In the U.S., food harvesting, processing, and transportation accounts for 10 percent of our energy. However, 40 percent of food goes uneaten and Americans are not only wasting the equivalent of $165 billion each year on this organic compound,… [more]
