According to our recently released 2018 Commercial Buildings Energy Consumption Survey (CBECS), the total floorspace in commercial buildings has increased but energy consumption has not, compared with our last survey (2012 CBECS). This difference indicates that the consumption per square foot (energy intensity) has decreased, which means that its efficiency has likely increased. The 2018 data showed […]

“At the start of the decade, the Solar Energy Industries Association (SEIA) announced a bold new vision, dubbing the 2020s the Solar+ Decade. SEIA’s goal is for solar energy to comprise 30% of the U.S. electricity mix by 2030. It’s been a turbulent start to the decade, but the story of this vision fundamentally shifted […]

A few days ago, I was driving home and my kids were standing near the driveway when I pulled my Bolt EUV into the driveway. From inside the car, I don’t hear much except the whine of the electric motors during takeoff from intersections or the regenerative braking when approaching a red light. But, one […]

One of the biggest obstacles to installing DC fast charging stations is getting it the big three-phase power it needs from the power company. This is not only expensive to put in, but makes for a huge bill every month (called demand charges). Demand charges are based on the maximum amount of power you use […]

Tesla’s AI Day livestream event is supposed to start in about 5 minutes. We’ve published some articles leading up to today’s event about what might be included, but there have been essentially no leaks about what will actually be covered. We’ll see! You can watch the livestream on Tesla’s website or via the embedded YouTube […]

Climate scientists described the gas leaks as a “reckless release” of greenhouse gas emissions that, if deliberate, “amounts to an environmental crime.”

Electric cars are the subject of political action in New York State and Georgia as leaders address the EV revolution.

One of the biggest challenges for electric boating is the water drag. Pushing a big boat to any real speed means expending a lot of energy, which cuts into range. Because batteries don’t hold as much energy per unit of weight and volume (low energy density) compared to fossil fuels, diesel and nastier bunker fuels […]

Yes, climate change. But, also: help!

As the world moves to electrify the transport sector, a lot of progress has been made in the passenger vehicle segment. In fact, the transition to electric mobility is happening a lot faster than a lot of people thought it would. For example, in Europe, 13% of new car sales were electric (21% plug-ins) last […]

Getting started with DC fast charging can be kind of intimidating. Charging at home? That’s easy. Just plug the thing in (assuming it’s been installed or you can use Level 1). But, when it comes to fueling up away from home, new EV buyers will often be used to the gas station experience, with an […]

In christening a new office of environmental justice, Environmental Protection Agency Administrator Michael Regan proclaimed Saturday that “underserved and overburdened communities are at the forefront of our work.” A stern test of that proclamation began just two days later. On Monday, the EPA held the first of three virtual listening sessions on the Biden administration’s proposal to strengthen its chemical disaster rule. […]
