Is PV Water Heating The Answer to Net Metering Changes in Nevada?

pv solar hot water heating element

The historic cost declines of solar panels make Photovoltaic Domestic Water Heating an attractive possibility for widespread domestic water heating. As far back as 2012, Mark Holladay of Green Building Advisors predicted the decline of flat plate and vacuum tube solar collectors.  Now, thousands of homeowners in Nevada could find heating large, well-insulated water tanks can ensure their solar panels maintain value. Solar thermal …

WILL DESALINATION UNDERMINE CALIFORNIA’S RENEWABLE ENERGY TARGETS OR BE A GRID RESOURCE?

Screen-Shot-2015-10-26-at-10.07.05-PM

LARGE, INFLEXIBLE DESALINATION PLANTS COULD JEOPARDIZE CALIFORNIA’S RENEWABLE ENERGY TARGETS AND INCREASE THE COST OF BOTH WATER AND ENERGY.  BETTER DESIGNED DESALINATION PLANTS CAN BE A GRID RESOURCE ENABLING RENEWABLE MICROGRIDS. Maintaining a balance on the electric grid used to be simple for utilities, just follow demand with turbine generators.  The electric utilities had a monopoly on generation and were incentivized to build plenty of infrastructure, so there was more than …
