The Tesla battery farm will be used to store energy and meet spikes in demand – like on hot summer afternoons when buildings start to crank up the air conditioning.

Develops a cost-benefit analysis to compare the impact of three separate policies to spur the additional production of ultralow-carbon fuels in California: a contract-for difference price guarantee, a per-gallon subsidy, and upfront capital grants.

The research report describes a study by Frank Gilliland and colleagues that was funded under HEI’s Accountability research program. The investigators collected air quality data and lung function and respiratory symptoms in three cohorts of children who participated in the Children’s Health Study in Southern California.

Companies worldwide are being warned that taking water preservation measures is now vital, and that those whole fail to act are likely to face mounting financial losses.

The goal of this work is to assess climate change and its impact on the predictability of seasonal (i.e., April–July) streamflow in major water supply watersheds in the Sierra Nevada.

Augmenting previous papers about the exceptional 2011–2015 California drought, we offer new perspectives on the “snow drought” that extended into Oregon in 2014 and Washington in 2015. Over 80% of measurement sites west of 115°W experienced record low snowpack in 2015, and we estimate a return period of 400–1000 years for California’s snowpack under the questionable assumption of stationarity. Hydrologic modeling supports the conclusion that 2015 was the most severe on record by a wide margin.

Cannabis agriculture is a multi-billion dollar industry in the United States that is changing rapidly with policy liberalization. Anecdotal observations fuel speculation about associated environmental impacts, and there is an urgent need for systematic empirical research. An example from Humboldt County California, a principal cannabis-producing region, involved digitizing 4428 grow sites in 60 watersheds with Google Earth imagery. Grows were clustered, suggesting disproportionate impacts in ecologically important locales.

Personal care products are a source of exposure to potentially endocrine-disrupting chemicals such as phthalates, parabens, triclosan, and benzophenone-3 (BP-3) for adolescent girls.
