BlocPower, 2013 CTONE Alum, and founder Donnel Baird is profiled in The Washington Post’s “Climate Visionaries” series.

While the COVID-19 pandemic and climate concerns continue to affect our lives, Cleantech Open Northeast alumni are making headlines as they strive to tackle the world's biggest and most pressing environmental and energy challenges.  They have adapted to the challenging circumstances and are addressing challenges related to water, waste, agriculture, transportation, information and communications, chemicals and advanced materials, energy generation, energy distribution and storage, and energy efficiency. Yet, even as we begin to transition back to "normal," serious events such as the heat waves wreaking havoc across the country and the severe drought out West, underscore the importance of our alumni's work to create a more sustainable and resilient future.
