A Peak Inside the Unisphere, One of the World’s Largest Net-Zero Buildings

December 31st, 2019 | by Guest Contributor

It is hard to build a net-zero building — one that produces more energy than it consumes — in the middle of a city. For one thing, nearby skyscrapers might block sunlight from reaching rooftop solar panels. For another, urban office buildings are cramped for space, and it generally isn’t possible to set up wind turbines on site


Green New Deals For The World Are Green Good Deals

December 29th, 2019 | by Mark Z. Jacobson

The Earth is rapidly approaching 1.5°C global warming, air pollution kills over 7 million people worldwide each year, and diminishing fossil fuel resources portend social instability. Yet, recently, world leaders at the United Nations Madrid climate talks failed to agree on a path forward. The core of the problem is the belief by some leaders that solving global warming will be expensive and drain the economy of their country. However, new research indicates that this belief is incorrect


EV Ownership + Rooftop Solar Ownership — New Report & Charts

December 25th, 2019 | by Zachary Shahan

We were curious whether EV ownership/leasing correlated with rooftop solar panel ownership, and also whether driving an EV encouraged people to drive more efficiently or even conserve energy more at home, so we surveyed thousands of EV owners. Guess what the results were


Bolt EV: Drive Unit Deep Dive

December 25th, 2019 | by Jennifer Sensiba

While batteries get a lot of attention, drive units in electric vehicles don't get as much love. Why? Because many think they're simple and all the same. An electric motor turns a reduction gear of some kind, which turns the CV axles, which turn the wheels and makes us go. It's just a few moving parts, right


Electrify America’s Reliable Fast Charging, & The Need For Autopilot — 2 Day, 4 State BMW i3 Road Trip

December 24th, 2019 | by Cynthia Shahan

The travel log of my trip from the Appalachians to Florida was quite different from my 3 day trip up. I again drove a 2015 BMW i3 REX with 71 miles of electric range. On the 3 day trip up to the Appalachians, I avoided using gas at all, going out of my way to find and use Level 2 chargers between the fast chargers. That is, until the last half hour to the mountain cabin


Washington State Ferries — Second-Largest Ferry Network — Switching From Diesel To Batteries

December 24th, 2019 | by Cynthia Shahan

Washington State Ferries will be following Ellen's example near the Danish island of Ærø. Washington often leads and succeeds where other states hover, discuss, and are quite too slow to transition. Washington also runs the second-largest ferry system in the world, so switching from diesel to batteries in the early part of a trend toward electrification in shipping is vital to set better standards in marine shipping


7 Challenges for Global Energy Transformation — Rocky Mountain Institute Report

December 19th, 2019 | by Cynthia Shahan

"Seven Challenges for Energy Transformation 2019," a report by Rocky Mountain Institute, was launched during three connected international events in Delhi, Beijing, and New York that convened the world’s leading energy stakeholders and catalysts to kickstart a global effort to accelerate the energy transition and mitigate the climate crisis


Sprint To Go 100% Carbon Neutral, 100% Renewable Electricity

December 16th, 2019 | by Cynthia Shahan

Sprint has indicated that it intends to source 100% renewable electricity and divert 50% of operational waste from landfills by 2025. This is what we need to hear on a day to day basis, from more and more corporations. While 2020 would be better, 2025 is not that far off, especially when you consider development timelines and corporate planning and budgeting challenges


Europe’s Green Deal: EU Commission President Ursula von der Leyen Announces “Europe’s Man on the Moon Moment” (Videos)

December 15th, 2019 | by Cynthia Shahan

As some act to stall progress, the forward motion provided by European Commission President Ursula von der Leyen and all she represents is a remarkable step forward. Presenting a Green Deal plan for Europe at the European Parliament in Brussels, Belgium, she and her colleagues took a seed from US progressives and gave it the watering and care it needed in the fertile ground of Europe


2012 Tesla Model S Crushes 2020 EV Entrants

December 15th, 2019 | by Johnna Crider

The 2012 Tesla Model S, despite being nearly 8 years old, is crushing the new 2019 and 2020 EV entrants on range and efficiency. In a tweet by our favorite Earl of FrunkPuppy, he shares a screenshot from the US government's Fuel Economy website, which offers comparisons between vehicles on key metrics


Six Flags Discovery Kingdom To Be 80% Powered By Solar Carport

December 13th, 2019 | by Cynthia Shahan

Borrego Solar Systems and sPower worked with the Six Flags Discovery Kingdom this year to manifest the first theme park on the West Coast powered by solar energy. In this case, the solar will account for 80% of the park’s energy usage. One difference in this theme park's solar installation from other similar installations is that it will be powered by one of the most substantial solar carport installations in the country


Electric Car Drivers: Demands, Desires & Dreams — New CleanTechnica Report

CleanTechnica has a new report out today, one highlighting the results of several thousand surveys of electric vehicle drivers in the US, Canada, and Europe. This initial report covers findings from North America and the UK. A coming report will cover the findings from the Netherlands, Norway, Germany, & France, and another one will cover the results from surveying non-EV drivers
