In July of 2017 (and previously), I put together a comparison of Tesla Model S sales and other large luxury car sales in the USA. A few people recently made me realize an update was in order. I didn't really have a clue how things would turn out this time around since I hardly follow the non-electric car market, but my hunch was that the Model S was still #1 in the large luxury car category

Solar chimneys are an ancient passive solar technology whereby natural heat convection processes are harnessed to provide ventilation, amongst other possibilities

Folding electric scooters? Sure, we've seen those before. But what about a folding electric scooter with connectivity? Let's introduce you to the UJET folding connected electric scooter

Solar energy has been exploited in direct capacities, for various purposes, well before solar photovoltaic cell and module technology became the most prominent example of "solar energy technology." Solar stills, solar cookers, sunlight concentrators, solar furnaces, solar fire starters, et cetera, have a long history of use and/or suggestion of use. For instance, there's fairly good evidence (though disputed by some academics) that solar fire-starters have been in use in Central Asia for a fair many thousands of years

As an addendum to our earlier article on passive solar house design basics, I thought that it would be worth providing an overview of some of the possibilities when it comes to the design of attached passive solar greenhouses and/or solariums

Sometimes, men just need to know that fighting climate change can also kick serious a**. And what better way than by forming an electric motorcycle gang

After the usual off-season (January and February), March came and electric car sales surged to 59,000 units in China, up 85% year over year (YoY). Quarter 1 2018 sales doubled compared to the same period last year, to over 122,000 units

The Netherlands had 1,834 registrations in March, up 123% compared to March 2017. Last month actually resulted in a 4.3% plug-in vehicle share of the auto market, thus helping the 2018 share climb to 3.3%. The Tesla Model S was once again the monthly best seller, thanks to 588 registrations, allowing it to beat its own record of 576 deliveries, which dated back from December

The Tesla "secret weapon" is not some new technological innovation, but rather it is a set of ideas proven effective by research and that can likely be found in a book titled something like: How to build a successful company for the future for idiots. No doubt, Musk has read extensive literature on the subject

I didn’t realize until late last year, October to be exact, that our local utility (spelled monopoly), Green Mountain Power (GMP), had to “open up” the area of our state for Tesla Energy to be even able to offer us a solar generation package. However, we timed our latest inquiry to Tesla Energy just right

The woman walks up to the door of the office with confidence and orders two new water filters and a single solar-powered lamp. The products were destined for a neighbor’s household after she saw the benefits they provided. The water in the Kupang neighborhood she lives in is chronically contaminated with silt and other particulates that the low-cost and easy-to-implement Nazava water filters remove time and time again

An electric car that runs on sunlight is bound to get the press going and commenters seething about whether the possibility is practical or not. But even if the technology is not 100% there yet, is it not reasonable to pay attention to the early startups that could potentially become tomorrow's established electric vehicle (EV) and autonomous vehicle (AV) leaders? In a rarefied field, Lightyear proposes the One, an EV that runs on sunshine ... somewhat

Average used plug-in electric vehicle resale prices rose by 41% in the UK during the first quarter of the year, the online used car service Autorola has reported

Tesla's production figures for the first quarter 2018 were released recently and provided great support to the company's mission to accelerate the adoption of electric cars. Elon Musk's company is under intense pressure as it strives to ramp up production of its first affordable car, the Model 3, which is seen as a game changer as it will appeal to a wide variety of customers, particularly with the forthcoming $35,000 base model.

Electric vehicle fever has definitely caught on in Germany, with March coming in as a record month to echo France's record month. Germany had over 6,700 electric car registrations last month, a 52% increase year over year (YoY). The plug-in vehicle share of the overall car market was 2%

France registered a record 5,402 plug-in cars in March, up 41% year over year (YoY). With all plug-in drivetrains working together (fully electric cars +40%, plug-in hybrids +45%), the plug-in market was pulled up to 10,892 units in 2018, up 17% Yo

The head of powertrain development at Volkswagen’s Porsche business, Joerg Kerner, has been arrested by authorities in Germany in relation to the Stuttgart public prosecutor office's investigation of the ongoing Volkswagen diesel vehicle emissions cheating scandal, unnamed sources quoted by Bild am Sonntag have revealed

The Sweden-based utility giant Vattenfall is now aiming to become the top operator of plug-in electric vehicle charging stations over the next 5 or so years, company execs have revealed

The UK’s electric vehicle (EV) charging infrastructure continues to grow strongly following a record quarter for EV registrations. A total of 12,825 new plug-in vehicles were sold between January and March 2018, a rise of 13.5% on the same period in 2017, with an additional 7,600 domestic chargepoints installed this year*
