World clean energy investment totalled $333.5 billion last year, up 3% from 2016 and the second highest annual figure ever, taking cumulative investment since 2010 to $2.5 trillion
The diesel generators can be switched off completely during the day. This is unnoticed by electricity consumers but has huge benefits for the electric utility company and the region - and a pioneer for more diesel-free zones worldwide.
Specialized PVD coatings and nitriding significantly increase the durability and lifespan of wind turbine components like roller bearings and planetary gears under metal-on-metal, high load conditions
There is no doubting the magnitude of opportunity facing the global solar industry now and in the coming years. However, the industry must reflect on past failures and put in place processes which ensure they are not repeated.
Peter Levring for Bloomberg Technology: Denmark obtained 43.4 percent of its electricity from wind last year, beating its own record. The government's goal is to derive 50 percent of the country's entire energy consumption from renewables by 2030.
Chelsea Gohd for Futurism: Solar-powered cars have been thought of by many as an impossible pipedream. But the innovators behind Lightyear One, a fully solar-powered vehicle to be released in 2019, just won an award for their design.
Clean Energy Collective (CEC), the nation's leading community solar developer and solutions provider, forecast what is on the horizon for community solar. CEC's experts offer the following 10 predictions for 2018.
Lorraine Chow for EcoWatch: The vision is so massive that the developers will have to construct a 2.3-square-mile artificial island in the North Sea to support the 10,000-turbine complex.
With ever-increasing panel efficiency, gross installation costs at under $4 a watt, and available tax credits to help defray the cost, there's never been a better time to consider this technology.
John Fitzgerald Weaver for Electrek: SmartWire is part of an industry wide remaking of 'busbars.' In order to squeeze greater efficiency from the same limited rooftop space, an evolution on the front side of the solar panel has been sped up.
David Grossman for Popular Mechanics: To build a photovoltaic highway, Chinese engineers are using three layers. The uppermost of these is transparent concrete with a feel similar to asphalt. Then come the solar panels, absorbing the sun's rays while protected from nature.
This article examines the hidden power-loss case study data from a utility scale array. The role of string-level monitoring in identifying hidden power losses and its use as a tool in maintaining a high-level PV array operational reliability will be discussed.
Futurism: The Byron Bay Railroad Company has created the first fully solar-powered train. While it doesn't travel long distances, it does prove that the Sun is a viable source of energy for passenger transportation.
Regardless of whether a tower company or an MNO is establishing a new tower site or upgrading an existing one, a hybrid power system is the clear answer to being able to balance customers' demands for network reach and reliability and operational demands
Alice Bell for The Guardian: A technique has been devised that allows electricity to flow directly from solar panels to electrified train tracks to the trains themselves making solar powered trains more feasible than ever before
