Concentrating solar power (CSP) has existed since 1866, but for the last couple of decades, photovoltaic (PV) has been the dominant solar technology. Now with technological advancements and energy storage, CSP is poised to make a significant comeback. 

In April, solar reached a new milestone, providing more than 2.3 percent of U.S. electrical supply, according to the latest issue of the U.S. Energy Information's (EIA) Electric Power Monthly, with data through April 30, 2017. Consequently, solar has now moved into third place among renewable sources — behind hydropower and wind but ahead of biomass and geothermal.

The New York State Legislature has sent to Gov. Andrew Cuomo companion bills that would lead to the development of an energy storage procurement target for the state.

The European Commission (EC) last week said that it has approved state aid for the conversion of a coal plant to biomass in Kalundborg, Denmark.

There are 185 sites in South Australia that are potentially suitable for off-river pumped hydro storage, according to the results of research at The Australian National University.
