The Path to Drawdown: Microgrid

Tackling climate change and staying below 1.5ºC of global temperature rise requires a massive scaling of emissions-free energy sources. Thankfully, renewable sources like solar and wind are quickly expanding their capacity worldwide. But to provide reliable clean energy to every household and organization in the world, we need a power grid that’s efficient and more resilient.

The power grid is the dynamic network of electricity generation, transmission, storage, and consumption that 85% of the world relies on. Microgrids, on the other hand, are localized groupings of distributed energy sources like solar and wind, combined with energy storage or backup generation and load management technology. Microgrids can operate as stand-alone entities or be plugged into the centralized grid as needed.

By enabling the integration of renewable energy sources into the grid, along with storage and demand management, microgrids can play a critical role in the advancement of a flexible and efficient electrical grid. More than 1 billion people -- around 17% of the global population -- still lack access to a centralized power grid. Microgrids can provide these people with energy access using low-carbon energy sources. In developed economies, the growth of microgrids is expected to strengthen the resilience of overall electricity grids.

What We Want to See Improve

Publish ESG Reports

CLSK’s 2020 Annual Report states (p. 8) that “no significant pollution or other types of hazardous emission result from the Company’s operations.” But because CLSK doesn’t track and publish environmental and sustainability metrics, we can’t evaluate these claims. Most importantly, we want to see the company tracking their GHG emissions so that investors can assess their climate impact.

Set Sustainability Targets

Once CleanSpark begins tracking sustainability metrics, they can start setting targets for the company to achieve in the next several years. These should be precise quantitative targets regarding reducing emissions and waste, with concrete timelines for achieving those targets. Ultimately, we want to see Cleanspark achieving zero scope 1, 2, and 3 GHG emissions in the near future.

Completely Base Bitcoin Mining to Renewable Energy

CleanSpark owns and operates CleanBlok, a bitcoin mining operation, and recently acquired ATL Data Centers LLC (p. 17), which runs thousands of Bitcoin mining units. While CleanBlok is advertised as being run on 95% carbon-free energy mix, we worry that bitcoin mining is still an energy-intensive activity. We urge CleanSpark to switch completely to renewable energy sources before expanding their bitcoin mining activity.
