Since they are “pages” and not “posts,” a couple of new CleanTechnica pages I just published aren’t going to feed into our home page, email newsletters, or RSS feeds, so I’m just dropping a note here to let you know that I just published these two pages: Solar Energy Resources Wind … [continued]
Recently on CleanTechnica there have been a couple of excellent pieces on the challenges with hydrogen fuel cells for vehicles in general, but how would they be for urban transit buses specifically? It’s instructive to look at an apples-to-apples comparisons of diesel, electric trolley and hydrogen buses traveling 100 kilometres in the USA. Diesel is, on … [continued]
So… I forgot about this Nissan LEAF Shopper Survey a few times now, but we got 155 responses from Nissan LEAF shoppers (and the last one came in just about 1 day ago), so I think it’s time to finally share the results. The most basic part of the sales process is something I … [continued]
Originally published on EV Obsession. It’s hard to get European-wide numbers for electric car sales. In fact, it’s hard to get numbers for almost any country in Europe. A Norwegian electric vehicle association was publishing Norway’s numbers regularly for awhile, as was a German car association for Germany, but neither of them have … [continued]
There’s an enduring myth related to wind energy and nuclear energy that needs to be put to bed. That myth is that only nuclear can be scaled to sufficient capacity to reduce the impacts of global warming, and that wind energy is much less scalable so it should be ignored. … [continued]
Over the past several years, the Sheerwind Invelox ducted turbine has managed to rack up a couple of million in grants and other investments according to reports and has built two small prototypes. According to its press releases it has a New Zealand distributor and a couple of pilot projects targeted for Dubai and Minnesota. It … [continued]
Recently energy towers have been back in the hype cycle, specifically the misnamed Solar Wind Energy Tower. How do they stand up to scrutiny? Well, there are numerous good reasons why they don’t appear to make much sense, but there’s one overwhelming piece of evidence that appears at the bottom … [continued]
Critical. Re: Hydrogen and Fuel Cell Vehicles/Environment. This letter deals with the three fundamental flaws in the promotion of Hydrogen and Fuel Cell Vehicles that seeks to exploit public concern for the environment and to trigger a profoundly counterproductive use of public funds in paving the way for carbon-intensive fossil … [continued]
Altaeros and their airborne blimp wind generator have benefited from a reasonable amount of press over the past few weeks. They had asked CleanTechnica to provide coverage as well, but when pressed for more details on the technology, were unwilling to provide them. The airborne wind energy space was given overview … [continued]
Originally published on Energy & Policy Institute. Wind farms reduce greenhouse gas emissions in the overall electrical grid on close to a 1:1 basis. Typical grids produce 800 g of CO2 equivalent (CO2e) per KWh generated by their mixes of fossil, nuclear and renewable generation, and wind energy displaces virtually all of … [continued]
