Cobalt is the most expensive raw material used for building lithium-ion batteries. Lithium-ion batteries are used in smartphones, laptops, and electric vehicles. In the past year, the price of refined cobalt has been above $20k. Also, in the past 5 years the demand for this element from the battery sector has tripled and is projected to double again by 2020.
The electricity industry is going through massive changes and this summer at PG&E I looked at heat pump water heaters as a way of addressing some of those challenges. I found that heat pumps have the opportunity to have positive net economic, environmental, and energy benefits under some scenarios.
This month’s Cleantech Forum in San Francisco convened a number of diverse, but similarly relevant panels and breakout sessions around the topics of clean energy and sustainability innovation. One panel topic in particular stood out to me as an often-overlooked piece of the sustainability puzzle: transitioning our exhaustive material flows into closed loops.
An overview of Smart Grid communication technologies. Part 1 describes AMI.
This year marks the 100th anniversary of meetings on the UC Berkeley campus which ultimately resulted in the establishment of the National Parks Service.

Over the past several decades, gas stations have remained largely immune to the disruption that has radically altered other industries. But as climate change continues to increase, the imperative for innovation at the pump will start to increase significantly.
The unrealistic cosmetic standards we expect from produce may not result in low veggie self-esteem, but they do have severe negative impacts on our food system and precious resources: about 20%-40% of food is wasted due to the aesthetic standards of food retailers.
