PHEVs are like communism — good in theory, but in practice, they haven't lived up to their promise. Why? Most owners don't plug them in, according to a new study. As a bridge to full EVs and as a way to cut emissions, they've failed. It's time to pull the plug. techcrunch.com/2026/02/24/i...

Hell hath frozen over? techcrunch.com/2025/11/13/t...

Exowatt thinks it has a way to make concentrated solar power not just profitable, but one of the lowest cost sources of 24/7 power available. The startup wasn't looking for more money, but data center fever meant that investors came knocking anyway. techcrunch.com/2025/11/13/s...

In a sign of the times, data centers will attract more investment this year than new oil supplies. And over the next decade, the majority of power for new data centers will come from renewables, not natural gas. techcrunch.com/2025/11/12/d...

What if Americans' dislike of trains stems from the fact that robber barons built and ran the first ones here? Maybe we're not skeptical of government projects — which also build highways — but instead harbor a distrust of wealthy profiteers, one that is etched in our national consciousness.

Arbor was built on the idea that burning biomass could benefit the grid and remove carbon. But over the last year, it has turned its self-described "vegetarian rocket engine" into an omnivore capable of burning natural gas and capturing the carbon. techcrunch.com/2025/10/24/a...

Google will build a natural gas power plant and capturing the CO2 emissions. Sounds good, right? One hitch: carbon capture and sequestration (CCS) hasn't exactly lived up to expectations, and that's before we start talking about methane. techcrunch.com/2025/10/23/g...
