Below are some are several recent talks which cover the range of my recent research activities and interests. I apologize for their large size. My presentations tend to be "graphically dense." This was as small as I could get them. Each is a two-page-per slide PDF. Please contact me if you require a version in a different format.
Design and Implementation of Future Energy Systems
The Devil is in the Details - or Is It?
Whether solar, wind or biofuels, or the efficient use of energy, tomorrow's clean energy options will be most successful when they embrace the details of renewable resource and other dynamics, and put that information to productive use. These dynamics occur all along the value chain, encompassing technology development, deployment and use.
All Energy Is Local
From the late 1960s to the early 1980s, my dad was head of public relations for Boston Gas (now Keyspan, soon to be National Grid). He was part of the team that put the rainbow on the LNG tank in downtown Boston. Could such a tank be sited there today? (Uh, no.) There is lots of controvery over the siting of energy facilities— all across the world. Lots of LNG terminals proposed in the Northeast. However, if cannot even site a renewable energy facility in international waters (e.g. the Cape Wind wind 'park'), can we site anything at all?
Emissions Reductions from Wind, Solar and Energy Efficiency
Avoided Emissions from Renewables:
Calculating the avoided emissions from renewables such as wind and solar is tricky business, especially when the amount of renewables is small relative to the regional grid. The dynamics of fossil unit dispatch, the cost of natural gas versus coal, and changes in electricity demand, all play as important a role as the solar and wind resource in determining whether a kWh of PV or wind offset a clean or dirty fossil generator.
Technological Opportunities and Challenges
Next to power generation, the use of energy for transportation is one of the largest contributors to greenhouse gas emissions. Unlike electricity, it is highly distributed in space and time, with quite different dynamics associated with the development, deployment and use of new technologies.
This talk highlights many of the challenges a transition to a cleaner transportation system. This includes both personal transportation and freight. Although new vehicle technologies (hybrids, HCCI, hydrogen) and alternative fuels (CNG, biofuels, hydrogen) are important, they are only part of the story. Improved (smarter) power trains and lighter vehicles are also important. Also essential is the "demand for transportation (right)." City design and zoning, as well as investments in public transportation and road networks, all affect how far—and fast—people and packages go, affecting overall fuel consumption and pollutant emissions.
