In recent years lithium-ion batteries have gathered bad press. They offer disappointing battery life for modern portable devices and limited driving range of electric cars, compared to gasoline-powered vehicles. Lithium-ion batteries also have safety concerns, notably the danger of fire. This situation raises legitimate questions: What is coming next?
The 50 individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.
Coating engine components with hard carbon reduces friction to almost zero - a development that could save billions of liters of fuel worldwide every year. Now researchers have developed a new laser method to apply the coating on the production line.
Researchers have found a more eco-friendly way to derive lignin - a paper industry waste product - from wood and convert it into chemical building blocks. The resulting chemicals can be used in paint, insulation foam, and several other products.
Today, the European Commission is launching the European Smart specialisation platform on energy, which will support regions and Member States in using Cohesion Policy funding more effectively for promoting sustainable energy. The Platform will help regions to share their expertise on sustainable energy investments and especially on the deployment of innovative low-carbon technologies.
A new study analyzes the required climate policy actions and targets in order to limit future global temperature rise to less than 1.5 degrees C by 2100. This level is supported by more than 100 countries worldwide, including those most vulnerable to climate change, as a safer goal than the currently agreed international aim of 2 degrees C - an aim which would already imply substantial greenhouse-gas reductions. Hence the interest for scrutinizing the very low end of greenhouse-gas stabilization scenarios.
It is six times more expensive for society - and for you individually - if you travel by car instead of cycling. This has been shown in a Lund University study of Copenhagen, a city of cyclists. It is the first time a price has been put on car use as compared to cycling.
