Calculating the rising energy demand for cooling

Due to climate change, the average global temperature will rise in the coming decades. This should also significantly increase the number of so-called cooling degree days. These measure the number of hours above a certain ambient temperature threshold at which a building must be cooled to keep the indoor temperature at a comfortable level. The rising values may lead to an increased installation of AC systems in households. This could lead to a higher energy demand for cooling buildings, which is already expected to increase due to climate change and population growth.

Getting 'wind' of the future: Making wind turbines low-maintenance and more resilient

A key driver of energy research is the ever-growing demand for energy. Traditional fossil-fuel-based energy sources currently meet these demands and do it well, but they're non-renewable and cause major environmental pollution. In a world with looming climate and resource crisis threats, researchers have turned to renewable sources of energy as sustainable alternatives. Among renewables, wind energy, in particular, has gained considerable attention due to its low cost. As Dr. Afef Fekih, Computer Engineer at the University of Louisiana, U.S., with a specialization in wind turbine design, notes, "Wind energy has been described as 'the world's fastest-growing renewable energy source,' seeing a 30% annual growth on average over the last two decades."
