CORNERSTONE INTERVIEW Neal Lewis Vivian Leber Sustainability Institute at Molloy College “It’s not acceptable for Long Island to have only 3% renewables, while California has 35%.” Long Island is endowed with a number of savvy environmental advocacy groups. Neal Lewis, Executive Director of the Sustainability Institute at Molloy College, is surely an advocate who walks the walk (he drives a Prius and follows a vegan diet). But he also defies certain expectations. First, he was at odds with other Long Island environmentalists in being the sole supporter of building the proposed new and sizable Caithness II facility in Yaphank. The super-efficient primarily natural gas-run electricity generation plant based on advanced German technology was meant to ensure meeting the region’s power demand needs even on the hottest summer days, thus eliminating the need to employ dirty, fuel-guzzling older plants. (Nonetheless, Caithness II was shelved by LIPA in 2014, when PSEG determined that the additional power capacity would be costly and redundant, though the project yet may be revived after a new comprehensive Integrated Resource Plan (IRP) is completed.) Let’s Get to 50/50 Second, Lewis believes that Long Island should realistically strive to reach the level of 50% renewable energy use by 2025, with the other 50% from new highly efficient fossil-fuel generation, which would quickly result in steep greenhouse gas reductions. Many renewables advocates want to shoot for 100%, and during the conversion shun all efforts to replace or modernize the old dirty plants in order to get more bang for the buck from burning fossil-fuels more efficiently. “Should we wait decades on modernizing the system unil we get to 100%, or simultaneously move up from the current level of about 3% renewables, while immediately reducing emissions dramatically with new modern natural gas plants as part of an integrated plan?” He explains that such a combined-cycle plant as Caithness II, which captures energy twice, would reduce carbon dioxide emissions by 40% over single-cycle old plants. If Caithness is not built then there will be an additional 1.1 metric tons of CO2 released annually, which is equal to the CO2 reductions from 467 Megawatts (about 77 turbines) of offsh
