How biofuels from plant fibers could combat global warming

Scientists, companies and government agencies are hard at work on decreasing greenhouse gas emissions that cause climate change. In recent years, biofuels produced from corn have emerged as a fuel source to power motor vehicles ...

New fuel cell demonstrates exceptional power density and stability

A team of researchers led by Northwestern University professor and fuel cell pioneer Sossina Haile has created a new fuel cell offering both exceptional power densities and long-term stability at optimal temperatures, a discovery ...

Axing fossil fuel subsidies scant help on climate: study

Getting rid of massive subsidies for oil, gas and coal will not significantly curb carbon pollution or speed the transition to a greener global economy, researchers said Wednesday, challenging widely held assumptions.

Diverse causes behind frequency fluctuations in power grids

The use of renewables like the sun and wind can cause fluctuations in power grids. But what impact do these fluctuations have on security of supply? To answer this question, scientists from Juelich and Goettingen worked together ...
