Researchers have made significant progress in understanding the fundamental microscopic mechanisms that can be used to customize materials for heat insulation. This breakthrough represents a significant step forward in the continuous endeavour to understand heat transport, improve energy efficiency and promote sustainability. Heat transport plays a vital role in numerous scientific and industrial fields, including […]

Electrifying long-haul cargo-carrying trucks was deemed financially unviable. However, recent findings from researchers at Chalmers University of Technology demonstrate that operating electric heavy goods vehicles can be more cost-effective than using diesel. The shift from fossil fuel-powered to electric vehicle fleets has primarily been noticeable in lighter vehicles like private cars and delivery vans. However […]

Even if we firmly go down the path of the low-carbon economy, the energy transition to renewables is only just beginning. We live now in a world that is still very much fossil fuel-based and the landscape of a fully renewable-powered future has not yet been shaped (and we might have to wait a few […]

“ Eat all your food, it can’t be wasted”. How many times have you heard that phrase from your parents? We did not know it, but they were right. Nowadays, a third of the food we generate is wasted. This generates both economic losses (~ $940 billion USD per year) and environmental problems (4.4 Gt […]

Renewable energy sources are crucial to react to the continuous increase of energy consumption and pollution by carbon dioxide emissions worldwide. Biofuels, where the energy content is derived from a biological source, are one of the alternatives to oil and natural gas. Still, some biofuels are controversial, like biodiesel, because they imply cultivating certain crops […]

Tides are more predictable than winds or sunshine. Then, why are not they already widely used as a source of renewable energy? The simple answer is that designing and building an ocean energy array is quite complex. This complexity has an associated variability in the cost of energy that makes projects difficult to evaluate from […]

From electric vehicles to storing wind and solar energy produced during off-peak hours, rechargeable lithium-ion (Li-ion) batteries are the best option that we currently have tu support our technological future. But if we want them to be truly environmentally-friendly and safe devices, they do need some changes. The Li-ion battery is a rechargeable cell. Typically […]

Nature is a source of inspiration for scientists. If the efficiency of natural processes efficiency has been honed by billions of years of evolution, it seems reasonable that the best way to achieve some process is to try and mimic what nature has already come up with. This is the case with photosynthesis, a process […]

Planes, ships, trucks and (most) cars run on different fractions of crude oil, composed of carbon chains of different length: Diesel (C 10 -C 22 ), kerosene (C 8 -C 16 ) and gasoline (C 5 -C 12 ). Despite their current supremacy, it is well known that fossil fuels will not be the energy […]

A tax on carbon emissions is an efficient way to make firms and consumers internalize the environmental costs due to climate change. However, there are many other aspects to consider in a transition from a fossil-fueled economy to a cleaner one. In a past article we presented the case for subsidies on research to develop […]
