A decade ago, wind power was already basically cost-competitive with conventional power sources, utility-scale solar was significantly more expensive but starting to bloom, and electric vehicles were hardly a blip on the horizon and basically unknown to most of us. How did that change in the past 10 years

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

It's not often that we write reviews of a bike helmet on CleanTechnica. For most people, and for most helmets, there's nothing special. You find one that fits on your head and that meets the applicable safety standards, adjust it to fit, and go. Lumos decided to go above and beyond the normal with their new Matrix helmet. Not only does it protect your head, but it has features that can help prevent an accident from happening in the first place

While recently traveling, I was cozy and tucked in bed under full sheets and comforter with the thermostat set to 65 degrees when a pang of guilt about this unnecessary energy usage hit me. I grumpily got out of bed to adjust the temperature when it hit me. As an advocate for energy-efficiency and climate-change efforts, I never would have set the thermostat so low if I was at home, so why did I act differently while in a hotel room in a different city?

Zachary Shahan, Director & Chief Editor at CleanTechnica, recently interviewed Thomas Samuel, founder of Sunna Design, a 2018 Zayed Future Energy Prize (ZFEP) winner. Every prize is a sweet acknowledgment of leadership in sustainable development and deep humanitarian efforts. Sunna is a kind business that brings light to undeveloped countries. It brings not only streetlights but also "nano grids" where energy is nonexistent or scarce.
The interview is a fresh exchange between two young, inspired fathers who are successfully supporting sustainability goals in different ways

LED lights are famed for their efficiency and low heat signature which created a market for outdoor LED street light fixtures that, as the cost of LED drivers has come down over the last 5 years, offer very attractive paybacks and significant energy savings and lower maintenance over the life of the fixture. We sat down with Current's Chief Marketing Officer Bruce Stewart at Current by GE's Hendersonville, North Carolina, factory to see where the brand is headed

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

But there is also good quality news out there if you let independent journalists communicate what they know best, fields they master for the purpose of bringing more light to important matters
