Rooftops on new buildings built in commercial zones in France must either be partially covered in plants or solar panels, under a law approved on Thursday.Green roofs have an isolating effect, helping reduce the amount of energy needed to heat a building in winter and cool it in summer.The argument for divesting from fossil fuels Read more about France decrees new rooftops must be covered in plants or solar panels[…]
That captures the most solar energy over the course of the day, which benefits the homeowner, but does so at hours that are not so helpful for the utility and the grid as a whole. Mount them to catch the sunlight from the west in the afternoon, and the panels’ production over all would fall, Read more about Why More Solar Panels Should Be Facing West, Not South[…]
As well as getting it from sunlight, it also grows on trees… A study, Sustainable Mallee Jet Fuel, commissioned by Airbus and undertaken at the Future Farm Industries Cooperative Research Centre, found that carbon emissions from jet fuel sourced entirely from mallee crops would emit 40 per cent less carbon than those using petroleum-based jet Read more about Jet fuel from trees![…]
With the first ever production of synthesized “solar” jet fuel, the EU-funded SOLAR-JET project has successfully demonstrated the entire production chain for renewable kerosene obtained directly from sunlight, water and carbon dioxide (CO2), therein potentially revolutionizing the future of aviation. This process has also the potential to produce any other type of fuel for transport Read more about Sunlight to jet fuel: European collaboration SOLAR-JET for the first time demonstrates the entire production path of “solar” kerosene[…]
Navy researchers at the U.S. Naval Research Laboratory (NRL), Materials Science and Technology Division, demonstrate proof-of-concept of novel NRL technologies developed for the recovery of carbon dioxide (CO2) and hydrogen (H2) from seawater and conversion to a liquid hydrocarbon fuel. The predicted cost of jet fuel using these technologies is in the range of $3-$6 Read more about Scale Model WWII Craft Takes Flight With Fuel From the Sea Concept – U.S. Naval Research Laboratory[…]

A hybrid conversion is a cutting-edge technology designed to transform your existing vehicle, or a new one via ship-thru installation, into a hybrid electric vehicle. XL Hybrids system is designed to work on the most popular Class 1-3 fleet vehicles, including cargo/utility/shuttle vans. By adding hybrid powertrains to your fleet, you can cut fuel costs, Read more about Convert your van into a hybrid for $8000,- and save around 20% fuel in urban environments[…]
