Can portable, personal cooling devices keep you cool in summer? And what are the potential energy/carbon benefits? I tested two quite different personal air conditioners.
New research shows fluid-filled roof panels that work like solar water heaters – except to extract heat from fluid, rather than adding it – can help make air conditioning up to 20% more efficient.
EVs are quickly becoming one of the largest flexible loads on the grid in some areas, with growth that parallels the increase in numbers of air conditioners years ago.
Gas was once considered a clean, green and cheap fuel. Now it is no longer clean, no longer green and certainly not cheap.
