Pouring over the line items on your monthly electricity bill may not sound like an enticing way to spend an afternoon, but the way electricity bills are structured has a significant impact on equitable energy access and distribution.

Improved Desalination Process Also Removes Toxic Metals to Produce Clean Water
-Adapted from UC Berkeley news release by Bob Sanders
Desalination - the removal of salt - is only one step in the process of producing drinkable water, or water for agriculture or industry, from ocean water or wastewater. Either before or after the removal of salt, the water often has to be treated to remove boron, which is toxic to plants, and heavy metals like arsenic and mercury, which are toxic to humans. Often, the process leaves behind a toxic brine that can be difficult to dispose of.

Concerns about climate change are driving a growing number of states, utilities, and corporations to set the goal of zeroing out power-sector carbon emissions. To date 17 states plus Washington, D.C. and Puerto Rico have adopted laws or executive orders to achieve 100% carbon-free electricity in the next couple of decades. Additionally, 46 U.S. utilities have pledged to go carbon free no later than 2050. Altogether, these goals cover about half of the U.S. population and economy.
These are ambitious targets, but a new look at the past 15 years in the electricity sector shows that large reductions in emissions are possible.
