David Wallace-Wells observes that few Silicon Valley titans are addressing climate change, despite the opportunity to leave a significant legacy. He points to Bill Gates-funded negative emissions technology, which could enable current industrial activity without global warming.

This technology would cost $3 trillion annually to operate worldwide. While substantial, this figure is less than the $5 trillion spent each year on global fossil fuel subsidies.

Wallace-Wells, author of [The Uninhabitable Earth: Life After Warming](https://amzn.to/2Of5N3y), shared these insights.

David Wessel's book, "Only the Rich Can Play," exposes the 2017 Opportunity Zone tax break. Intended to aid underserved communities, this initiative, passed with little scrutiny, primarily benefited wealthy areas like the Las Vegas Strip, allowing investors to avoid capital gains taxes.

Wessel's analysis details the program's failures and limited successes, offering lessons for better design. Join David Wessel (@davidmwessel) and Lenny Mendonca for an in-depth discussion on this system, which Wessel argues keeps the rich richer. This event was presented by The Commonwealth Club of California.

Northern Ireland is embarking on a cleaner energy future, utilizing abundant wind and solar resources. While engineers drive innovation, widespread public and community support is crucial. We need open dialogue to connect green energy projects with climate benefits, helping individuals make informed choices and embrace new infrastructure. This collective effort is vital to transform NI's power system for future generations.

Dr. David McGowan, a Senior Lead Engineer at SONI, is key to this transition. He led SONI’s Tomorrow’s Energy Scenarios, outlining decarbonization pathways for NI. Also a steering group member for ENTSOE, he contributes to long-term EU energy scenarios. This talk was given at a TEDx event. Learn more at ted.com/tedx.
