The premise of these articles is that solar thermal is dead because “It’s now cheaper to use a photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. system to heat domestic hot water.” These two articles have been very widely circulated and remain very much with us today.

Have you ever wanted X-ray vision, or to see the hidden features of your home? The City of Vancouver has launched a new effort to make energy use more visible to its residents, complete with rainbow-colored images of their homes that show details invisible to the naked eye.
